HIGHLIGHTS - 1974-75 



For Hetch Hetchy, fiscal year 1974-75 has been a record year in 
many ways. The heavy rainfall and snow on the Tuolumne River 
Watershed during the past two years have brought higher-than- 
normal inflows. With all project reservoirs assured of filling 
and spilling, our efforts were bent on channeling the maximum 
available water for electric power production and on minimizing 
spill after the reservoirs have been filled. The success of 
these efforts is shown by department's electric system output 
of 2,057,609,000 kilowatthours for 1974-75, a new record for 
total project hydroelectric generation for one fiscal year. 



1 - 



During the year, Hetch Hetchy furnished 588,989,569 kilowatthours 
to seven industrial customers located in Alameda, Santa Clara 
and Stanislaus Counties, for a revenue of $7.9 million. Both 
sales and revenue represent records unmatched in Hetch Hetchy' s 
history. The impact of the revenue becomes even more dramatic 
when it is shown that the same number of kilowatthours sold to 
these customers in fiscal year 1969-70 would have returned little 
more than half as much revenue. 

The record generation and the high industrial power rates combined 
have boosted the department's total revenue from sale of electric 
energy to a new high of $18.5 million in 1974-75, an increase of 
$4.5 million over the last fiscal year. Compared with the previous 
high of $15.0 million for fiscal year 1970-71, the increase is 
still a sizable $3.5 million. 

Surplus earnings enabled the department to make available $1.0 
million to the City's general fund in 1974-75, hopefully marking 
the beginning of many such contributions. 

Negotiations to extend the March 14, 1945 "Main Contract" between 
PGandE and City beyond the expiration date of July 31, 1975 were 
concluded with the execution of an amendment agreement dated 
June 24, 1975. This contract covers, among other things, the 
services which the Company performs in wheeling Hetch Hetchy 
energy to City's municipal consumers in and out of San Francisco. 
Through bargaining based on the cost-of-service principle and on 
the changes in conditions incident to wheeling of Hetch Hetchy 
power by Company over the last three decades, City negotiators 
were able to obtain for the City prospective annual net savings 
in the amount of $290,000.

HETCH HETCHY ORGANIZATION AND FUNCTIONS 

Under policies established by the San Francisco Public Utilities 
Commission, the HETCH HETCHY WATER AND POWER DEPARTMENT and the 
BUREAU OF LIGHT, HEAT AND POWER serve the City and County of 
San Francisco in the dual function of operating department and 
service bureau. 

Hetch Hetchy* is a municipally-owned system of storage reservoirs 
and aqueducts which collects water from the Tuolumne River water- 
shed and delivers it to the San Francisco Water Department. As 
a by-product of falling water, Hetch Hetchy operates and maintains 
hydroelectric generating stations and high voltage transmission 
lines for the production and distribution of electric energy. 

Through its Transit Power Division, Hetch Hetchy has funded, 
operated, maintained and provided improvements for the electric 
facilities of the San Francisco Municipal Railway since July 1, 
1969. 

All of Hetch Hetchy' s expenses, including those of the Transit 
Power Division, are supported by water and power revenues. 




NEW MOCCASIN POWERHOUSE AND PENSTOCK 



* Hetch Hetchy is an Indian name for the valley in the 
Sierra where the Department's first dam was built. 



The Bureau of Light, Heat and Power administers contracts for 
furnishing electric, gas and steam services to municipal depart- 
ments and handles monthly billings. It also administers contracts 
for furnishing street lighting services and for operation and 
maintenance of City-owned street lighting. Financing, design 
and construction of City-owned street lighting improvements are 
under the jurisdiction of the Department of Public Works, and 
plans for these improvements must be approved by the Public 
Utilities Commission through this Bureau. The Bureau is financed 
by appropriations from municipal departments and gas tax funds. 

For fiscal year 1974-75, the Department administered budgeted 
funds for all purposes as follows:

HETCH HETCHY WATER AND POWER SYSTEM 



REVENUES AND EXPENDITURES 



Revenue from Hetch Hetchy Water and Power operations is derived 
principally from two sources: 

1. Sale of electric power and energy to San Francisco Municipal 
departments, Modesto and Turlock Irrigation Districts in the 
San Joaquin Valley, and seven industrial customers: 



Kaiser Cement and Gypsum Corporation 

Kaiser Aluminum § Chemical Corporation 

Lockheed Missiles and Space Company, Inc. 

General Motors Corporation 

IBM Corporation 

Liquid Air, Inc. 

Norris Industries, Riverbank 



Santa Clara County 
Santa Clara County 
Santa Clara County 
Alameda County 
Santa Clara County 
Alameda County 
Stanislaus County 



2. Sale of water to the San Francisco Water Department. 

This past year, revenue from sale of water and standby service 
to the San Francisco Water Department was $6,500,000. 

Gross sale of electric energy amounted to $18,484,718 compared to 
$14,104,677 during the year 1973-74. This increase in electric 
revenue in part reflected the increase in actual sales during the 
year; 2,025,074,464 kilowatthours as compared to 1,823,491,146 
kilowatthours for 1973-74.

HETCH HETCHY EXPENDITURES 



FISCAL YEAR I 974 -75 



POWER SALES 



Power and energy delivered to all City Departments decreased 0.31 
over the previous year, totally the result of reduced consumption 
at the San Francisco International Airport. The Airport, usually 
the single biggest energy consumer of the City departments, 
contributed significantly to the overall result with a 4.4% 
reduction, while all other City Department showed increases varying 
from 0.71 for street lighting to as much as 8.9% for the San 
Francisco Water Department, principally for pumping load. 

Hetch Hetchy power is sold to City Departments at cost, representing 
a saving to taxpayers for 1974-75 of approximately $4 million 
compared to the cost if supplied by the local investor-owned 
utility at current rates which are more than 50% higher than those 
if effect some four years ago because of continued escalation in 
fuel prices. 

Power and energy delivered to 
Modesto Irrigation District, 
Hetch Hetchy 's largest power 
customer, and to Turlock 
Irrigation District, the third 
largest, decreased by 7.71 and 
27.61 respectively this year. 
The reason for the Districts' 
decrease is due largely to the 
fact that more than normal gen- 
eration was available from their 
own generating plants because 
of the increased water storage 
behind Don Pedro Dam resulting 
from three successive above- 
normal-precipitation years. The 
effect of Don Pedro storage on 
each of the two Districts is 
different. It has less effect 
on Modesto's purchase, since 
Modesto normally generates less 
than 20% of its total load require 
ments. Turlock's own generation 
in 1974-75 accounted for nearly 
70% of its total requirements, 
MOCCASIN SWITCHYARD which is about two-thirds of 
AND PENSTOCK Modesto's. 




Gross sale of electric energy amounted to $18,484,718 compared to 
$14,104,677 during 1973-74. This record increase in revenue can 
be attributed to three reasons: (1) As a result of higher-than- 
normal precipitation on the Tuolumne River watershed the past two 
years, total electrical generation of the Hetch Hetchy powerhouses 
increased from 1,992,850,000 kilowatthours in fiscal year 1973-74 
to 2,057,609,000 kilowatthours in fiscal year 1974-75, an increase 
of 3.25 percent. This establishes a new record for total project 
electrical generation for one fiscal year. (2) The withdrawal 
of 123,458,969 kilowatthours of electrical energy which was deposited 
the previous year under City's "banking" arrangement with the Pacific 
Gas and Electric Company and (3) The sale to industrial customers 
at the high PGandE rates of 567,294,414 kilowatthours of energy, 
an increase of 2 1/2 times as compared to 227,596,800 kilowatthours 
for 1973-74. 

Another favorable effect of the record generation is the decrease 
in expenditure for supplementary power and energy from $447,270 
to $99,734. 

In order to guarantee a market for the large quantity of excess 
energy which was deposited with the Company in 1973-74 and which 
would be withdrawn this year, the Pacific Gas and Electric Company 
assigned to the City, as a temporary accommodation, four additional 
industrial customer loads during the year, namely: Liquid Air, Inc. 
in Union City under an agreement dated August 12, 1974, Lockheed 
No. 2 in Sunnyvale, General Motors Corporation in Fremont and IBM 
Corporation in San Jose, all under individual agreements dated 
September 10, 1974. 

October 29, 1974 marked the beginning of negotiations with the 
Pacific Gas and Electric Company for extension of the March 14, 
1975 "Main Contract" between the Company and the City and County 
of San Francisco. This contract, which expires July 31, 1975, 
covers such items as the wheeling of Hetch Hetchy power to the 
City's municipal customers, and the furnishing of supplementary 
energy and standby service to the City. These negotiations 
entail extensive review and analysis of the cost of service to 
various municipal loads. In order to assist and advise the Hetch 
Hetchy staff in these negotiations, the Public Utilities Commission 
authorized the employment of an expert consultant, Mr. Roy A. Wehe. 
After seven months of fruitful exchanges, negotiations were sat- 
isfactorily concluded with the execution of an amendment agreement 
on June 24, 1975. These negotiations have resulted in prospective 
annual net savings to the City for wheeling charges in the amount 
of at least $290,000. 



9 - 



On May 27, 1975, the San Francisco Public Utilities Commission 
adopted a new set of rate schedules for the sale of Hetch Hetchy 
power to private consumers and the Municipal Departments of the 
City, replacing a similar set which had been in effect since 
July 1, 1958. At about the same time, a staff study to determine 
the cost to serve the City departments was also made. It was 
found that based on test year 1973-74, a zero discount applied to 
billings for energy supplied to the San Francisco International 
Airport for resale to its tenants and a 45.5% discount to billings 
for energy supplied to City Departments for Municipal purposes 
would permit the recovery of cost. It is estimated that beginning 
July 1, 1975, the change in rates together with the change in 
discounts for the City dppartments will increase Hetch Hetchy' s 
annual power revenue by one million dollars.

HETCH HETCHY POWER SYSTEM OUTPUT 



WATER PRODUCTION AND TRANSMISSION 

Precipitation recorded for the year at our measuring stations was 
1071 of the long term average. 

During the year, 80,321,370,000 gallons of water were diverted 
from the Tuolumne River watershed through the Hetch Hetchy Aqueduct 
to the San Francisco Water Department, representing 86% of the 
City's total customer consumption. In addition, 236,999,312 
gallons were delivered to the United States Atomic Energy Commission 
at Mocho Shaft of the City's Coast Range Tunnel for use at the 
Lawrence Radiation Laboratory at Livermore; 49,229,620 gallons 
were delivered to Groveland Community Service District in Tuolumne 
County from the Mountain Tunnel.

OPERATION AND MAINTENANCE - MOCCASIN DIVISION 

Holm Powerhouse Unit No. 2 Generator 

The No. 2 generator at Dion P. Holm Powerhouse was shut down by 
protective relays at 6:26 p.m. on Sunday, January 5, 1975, indi- 
cating a failure to ground in the stator winding. Immediate 
preliminary investigation established that the fault was confined 
to Phase C of the 3-phase winding. The following day it was 
determined that the fault was limited to a single coil in a slot 
location that was readily accessible. It was also determined 
that bypassing the defective coil and then restoring the circuit 
continuity would be a simple solution, one that would not affect 
the operation of the generator adversely. An Allis-Chalmers 
Corporation factory engineer was contacted and repair efforts 
were begun. The repairs were made by departmental forces under 
the supervision of the Allis-Chalmers representative and the 
unit was restored to service on the following Sunday, January 
12, 1975. The total outage of the unit was therefore limited to 
only one week by the fortunate location of the fault and swift, 
concentrated efforts by departmental personnel.

The Kirkwood Powerhouse Phase B transformer for Unit No. 1 that 
failed on January 3, 1974, was repaired, tested and returned 
to service on September 4, 1974. The substitute transformer 
which was rented from PGandE for the duration of the repair 
work was shipped back to PGandE. The use of the substitute 
transformer, which enabled the powerhouse to operate at full 
capacity from February, saved the City more than $150,000 per 
month during the period of repair, about six months.

OPERATION AND MAINTENANCE - TRANSIT POWER DIVISION 

The Transit Power Division is responsible for supplying the 600 
volt direct current power that is necessary to operate the street- 
cars and trolley coaches of the San Francisco Municipal Railway. 
The Division is composed of two sections: Motive Power and 
Overhead Lines. 

MOTIVE POWER SECTION 

This Section operates and maintains seven substations which con- 
vert electric power from 12,000 volts alternating current to 600 
volts direct current by means of motor-generators, synchronous 
converters, and mercury arc rectifiers. (See Appendix Table 3 
for statistical data.) Motive Power is also responsible for 
maintaining the electric motors and associated control equipment 
for operating the cable-winding machinery located in the Cable 
Car Powerhouse at Washington and Mason Streets. In addition, 
Motive Power is also responsible for periodic inspection, clean- 
ing, adjusting and repairing the streetcar and trolley coach 
recorders at Central Control of the Municipal Railway. The 
substations operate 24 hours per day, 7 days per week, 365 days 
per year. 

On December 30, 1974 the 700 horsepower motor which drives the 
Cable Car System, failed due to an internal electrical fault. 
Our powerhouse electricians disassembled the motor and found the 
fault in the wound rotor. A local motor repair shop (Reyna 
Electric) was able to repair the damaged winding without the 
delay and expense of rewinding the rotor. Our powerhouse elec- 
tricians reassembled the motor, tested it and returned it to 
service on January 15, 1975. 

The following day (January 16, 1975) the other motor (750 hp) 
which drives the Cable Car System failed to start. Our power- 
house electricians disassembled it and found it had a fault 
similar to that found in the 700 hp motor. Again, Reyna Electric 
was able to repair the fault without rewinding the rotor. Our 
powerhouse electricians reassembled the motor, tested it and 
made it available for service on February 19, 1975. 

While the rotors were being repaired, the stator coils and 
housing of both motors were cleaned, inspected, painted with 
insulating enamel and dried using heat lamps. 



- 17 



Because the Cable Car System frequently overloaded its driving 
motor and caused the protective overload sensor to disconnect 
the motor by tripping its circuit breaker, a recording ammeter 
was installed in the switchgear panel to monitor the load. The 
recorder subsquently showed that the cable system load was far 
exceeding the rating of the driving motors. 

OVERHEAD LINES SECTION 

The primary function of the Overhead Lines Section is to maintain 
the trolley wire overhead facilities and the electric distribution 
system (both overhead lines and underground cables) which conveys 
power to it. Secondary functions include the maintenance of the 
Municipal Railway Signal Systems and the electric light and power 
systems of all Municipal Railway buildings. 

During the fiscal year 1974-75, the Overhead Lines Section responded 
to 4,184 emergency calls. In addition to emergency calls, this 
section has a regular and extensive maintenance program for over- 
hauling all overhead and underground facilities. This section 
operates with three shifts per day, seven days a week. Monday 
through Friday, the normal workday shift is from 8:00 a.m. to 
3:00 p.m. with a two-man emergency crew on the "swing" or evening 
shift (3:30 p.m. - 10:30 p.m.) and the graveyard shift (1:00 a.m. 
- 8:00 a.m.). On Saturdays, Sundays and holidays there is a two- 
man emergency crew on each of three eight-hour shifts; midnight 
to 8:00 a.m., 8:00 a.m. to 4:00 p.m., and 4:00 p.m. to midnight. 

Overhead and underground facilities are systematically inspected, 
and worn or damaged parts are replaced before they can cause 
accidents or malfunction of equipment. 

A considerable amount of damage to overhead facilities was caused 
by trolley coaches dewiring and snagging their poles in the over- 
head facilities and tearing them down, or by breaking the spans 
with the flaying poles. Such damage is repaired at no cost to 
the Municipal Railway. Other parties who damage our facilites 
are billed for the cost of repairs. This includes damage to 
overhead facilities caused by high loads on trucks or careless 
operation of crane equipment and damage to underground feeder 
cables by contractors digging into our duct lines. During 1974-75, 
responsible parties were billed for 14 damage cases totalling 
$16,702.95. The overhead Lines Section also performed work for 
building owners and contractors under work orders amounting to 
19 jobs totalling $24,545.24. This work included moving trolley 
poles to accommodate driveways; relocating trolley poles and 
feeders to permit construction of new buildings; temporarily 



removing trolley wires and feeders to permit passage of high 
loads; and shifting of trolley wires and feeders for various 
excavations . 

The Overhead Lines Section engaged in many other activities of 
a related nature which it is especially equipped to perform. 
These additional duties include repairs, maintenance and construc- 
tion of electrical systems in Muni's car barns, offices and shops; 
welding and rebuilding of worn overhead lines special work; 
making and rebuilding parts for switches, warning block signals, 
car recorders, and strand alarms for the cable car system; 
installing mobile radio equipment; installing streetcar and bus 
stop signs and public information signs.

In response to a request from a neighborhood association to 
paint poles along Sutter Street to improve the street's appear- 
ance, contract plans and specifications for painting have been 
completed. The contract is scheduled to be let in September 
1975. Both City and PGandE facilities will be painted under 
this contract and an agreement has been negotiated with PGandE 
for payment of its share of the work. 

POWER IMPROVEMENT PROGRAM 

Work during fiscal year 1974-75 under the Federal Grant of $19.8 
million (total Project Cost of $29.65 million) approved by UMTA 
for the Power Improvement Program was as follows (for construc- 
tion work in progress during 1974-75 please refer to Table 18 
in the Appendix) : 

1. Grant Amendment 

An amendment increasing the total Project Cost to $57.7 
million and the Federal Grant to $42.1 million was submitted 
to UMTA for approval on February 24, 1975. Since the prep- 
aration of the original budget, certain operating criteria 
and power requirements of the new subway-surface light rail 
vehicles have changed or have become better defined. The 
effect on the power supply and distribution system was 
evaluated by an updating of the conceptual design approved 
by UMTA. The final report was received after approval of 
the Project grant and budget. Subsequent detailed engineer- 
ing design has developed more realistic cost estimates. 
Unprecedented inflationary trends in materials and construc- 
tion costs have resulted in greatly increased costs.

Building designs for the six new substations, except for 
Taraval, received Phase II approval by the San Francisco 
Art Commission. Final (Phase III) apparoval for three 
of these substations, Laguna Honda, Judah and Carl, 
also received from the San Francisco Art Commission. 

B) Substation Sites 

All substation sites have received approval of the City 
Planning Commision for conformance to the City Master 
Plan, with the exception of Taraval as noted hereinafter 
due to necessity of alternate sites. 

Independent appraisals by two outside real estate appraisal 
firms were completed for all new substation sites. 

Jurisdiction of the Laguna Honda Substation site was 
transferred from the City Health Department to Hetch 
Hetchy by the Board of Supervisors on December 12, 1974. 

Following concurrence by UMTA on the purchase price for 
Judah Substation site, the Public Utilities Commission 
adopted a resolution which approved the acquisition and 
recommended to the Board of Supervisors that they approve 
the acquisition. The Board of Supervisors approved the 
acquisition. The site was vacated as of June 13, 1975; 
keys to the existing building were delivered to Hetch 
Hetchy by the Real Estate Department. 

- 26 - 



Negotiations for the Taraval Substation site, a privately 
owned vacant lot, brought out the possibility of Eminent 
Domain action to acquire the property. UMTA has concurred 
with the price offered and the use of Eminent Domain 
action. Authority to proceed with Eminent Domain pro- 
cedure for acquisition of this approved Taraval Substation 
site near 32nd and Taraval was withheld by the San 
Francisco Board of Supervisors' Finance Committee at 
their meetings on January 15 and January 29, 1975. At 
their direction, alternative sites have been found on 
Taraval Street near 40th Avenue and 42nd Avenue. 

Environmental Impact Data on the alternative sites, to 
supplement that on file, was forwarded to UMTA, as 
requested, prior to approval by UMTA of proceeding with 
real estate appriaisals as the first step in acquisition 
of one of the sites. 

A supplementary Environmental Impact Statement on the 
alternative Taraval sites was filed with and evaluated 
by the San Francisco City Planning Department, in 
accordance with the California Environmental Quality 
Act of 1970, with the finding that the project could 
have no significant effect on the environment. A 
negative declaration was prepared, posted, and advertised, 
and it received no notice of appeals within the required 
time limits. An EIR will not be required. 

City Planning Department was requested to review the two 
alternative Taraval Substation sites for conformance with 
the City Master Plan. 

Acquisition of either of the two alternative Taraval 
Substation sites was approved by UMTA on March 16, 1975. 
Community approval of both sites was received from the 
Taraval - Parkside Merchants Association and the Parkside 
District Improvement Club. The two sites are being 
reviewed by City Planning for Master Plan Conformance. 
Real Estate Department is proceeding with the ordering 
of independent appraisals of the sites. 

Negotiations with Pacific Gas and Electric Company for 
an easement for the Randolph Substation site, and for 
the relocation of PGandE energized underground electric 
distribution facilities within the easement, was completed. 
A rear yard variance to provide space for the Randolph 
Substation Building was granted by San Francisco Planning 
Department. A work order to PGandE for relocating their 
electric distribution facilities from the proposed 

- 27 - 



Randolph Substation site was transmitted to UMTA for 
approval on April 9, 1975. The work order was approved 
by UMTA on June 2, 1975, and was certified by the City 
Controller on June 17, 1975. The work order will become 
effective after PGandE grants the easement for the sub- 
station to the City. Legislation necessary for the 
acquisition of the easement is underway. 

Meetings were held with San Francisco Redevelopment 
Agency, City Real Estate Department and Hetch Hetchy to 
develop the terms for use of the Fillmore Substation 
site to be obtained from the Redevelopment Agency. 

C) Equipment Purchase 

Work commenced on fabrication of substation equipment. 
Meetings were held with ITE Imperial Corporation to 
review technical specifications and to coordiante 
delivery of equipment with future contracts for con- 
struction of substation buildings and installation of 
equipment. Shop drawings, wiring diagrams and other 
equipment data are continuing to be submitted for 
approval and are reviewed by Hetch Hetchy and our con- 
sultant, Bechtel. Equipment modifications, required 
by detailed design criteria and increased Project 
requirements, are being processed. 

4. Control and Communication Project 

The negotiated agreement between Systems Control, Inc. and 
the City was approved by UMTA on September 6, 19 74. The 
agreement was certified by the City Controller on December 
30, 1974 and work began on January 15, 19 75. Following a 
meeting held on January 22, 1975 with Hetch Hetchy to 
establish project schedule, identify key design criteria 
and to cover interfaces of this project with other portions 
of the Power Improvement Program, the consultant began

BUREAU OF LIGHT, HEAT AND POWER 



STREET LIGHTING 

General 

The lighting of public streets within the City of San Francisco 
is provided by facilities which are, on a City-wide basis, 42.5% 
owned by the City; 55.6% owned by the Pacific Gas and Electric 
Company; and a small percentage, 1.91, jointly owned. In the 
underground areas, where the economic advantage of City owner- 
ship is greatest, 81.1% of the lights are City-owned. Five 
years ago, the corresponding figure was 70.6%. 

In fiscal 1933-34, the cost for street lighting was $1.25 per 
capita; last year, with approximately thirty times as much light 
on the streets and public thoroughfares , the cost per capita was 
approximately $1.83 .

Maintenance and repair of City-owned installations was performed 
under two contracts. One provided for group replacement of lamps 
in accordance with schedules developed by the Bureau. A second 
contract covered work required for repair of damaged and defective 
equipment, painting and miscellaneous maintenance. 

Under contract, the Pacific Gas and Electric Company furnished 
street lighting service as directed, including the furnishing, 
maintenance and operation of Company-owned facilities. Certain 
services were provided also for City-owned facilities, including 
switching and control, replacement of individual lamps and globes, 
and emergency work required during other than normal working 
hours. Electric energy for all City and Company-owned street 
light operation was supplied by the Hetch Hetchy power system. 

Engineering 

The Bureau review, recommends changes, approvals or rejections 
of, and correlates all street lighting installations, including 
that dome by the Department of Public Works, the Pacific Gas and 
Electric Company, the Bay Area Rapid Transit District, the 
State of California, subdividers, etc. 

During the fiscal year 1974-75, 13 street lighting contract, 
involving a total of 641 new street lights, were approved by 
the Public Utilities Commission. Plans were submitted for 
approval only after careful checking to determine that illu- 
mination will exceed the minimum requirements established by 
the American National Standards Institute; and that all materials 
used, and manner of installation, meet with the applicable local, 
State and Federal rules, regulations and statutes governing the 
installation of electrical works. 

Operation and Maintenance 

As of June 30, 1975, a total of 37,061 City-owned and Company- 
owned street lights were in service in public streets, parks, 
viaducts, overcrossings , tunnels and underpasses. A summary 
of the number and type of units in service at the end of the 
fiscal year is shown in Appendix Table. 

A total of $1,281,316 was expended for operation, maintenance, 
and repair of the street lighting system. Of the total cost, 
$12,614 was paid by the State for its share of the operation and 
maintenance of street lighting at inersections on City streets, 
which are part of the State Highway system. During the fiscal 



38 - 



year, there were 119 accidents involving damage to City-owned 
street lighting property. Investigation was made, as soon as 
possible, to remove hazards to the public and obstructions to 
traffic. Total cost of repairs to damaged City-owned street 
lighting property was $60,732. Every effort was made to secure 
reimbursement for damages incurred from responsible parties. 
Previous experience indicates that approximately three-fourths 
of the repair costs will be recovered. 

Complaints 

During the year, 50 complaints requiring field investigation 
were received and acted upon. These complaints concerned 
inadequate illumination, objectionable glare in windows, and 
requests for temporary and permanent relocation of street 
lighting poles. 

Improvements 

During the fiscal year 1974-75, a total of 304 new City-owned 
street lights were placed in service at a cost of $420,433. 
Improvements were financed by State Gasoline Tax and the 1972 
Street Lighting Bond Issue as indicated in Appendix Tables 16 
and 17. 

UTILITY SERVICES TO MUNICIPAL DEPARTMENTS 

General 

Electric energy supplied to municipal departments is generated 
on the Hetch Hetchy power system and delivered to various service 
points by transmission and distribution facilities of Pacific 
Gas and Electric Company under a wheeling contract. Natural 
gas and steam supplied to municipal departments are furnished 
by the Pacific Gas and Electric Company under a service contract. 

Municipal Consumption of Electricity, Gas and Steam 

During the fiscal year, 478,595,675 kilowatthours of electrical 
energy were consumed through 1,003 municipal accounts at an 
expenditure of $4,905,273. Of the above, 147,431,772 kilowatt- 
hours of energy were supplied to the San Francisco International 
Airport for resale to tenants. Natural gas consumption was 
17,984,305 therms through 556 accounts at a cost of $1,855,530. 
One account consumed 610,200 pounds of steam at a cost of $1,475. 

There were six increases in gas rates last year which increased 
the cost to municipal accounts by approximately $474,246. 

A summary of consumption and expenditures for these commodities 
is shown in Tables 12 and 13.

HETCH HETCHY WATER AND POWER DEPARTMENT 
ORAL L. MOORE - General Manager 



This report is respectfully dedicated to 
Hetch Hetchy employees, past and present, 
whose devoted nnd conscientious efforts have 
made possible these accomplishments for 
San Francisco. 



The picture on the front cover of 0' Shaughnessy Dam 
was taken on June 7, 1923, before the dam was raised 
an additional 85.5 feet. 



In the 75th year since the first lands were acquired for the 
Hetch Iletchy Water and Power system, and in the midst of a very 
dry year, it is fitting to recognize the foresight, industry 
and dedication of the people who conceived, huilt and operate 
that system. One and three-quarter million San Francisco Bay 
Area residents receive a supply of first quality water from 
Hetch Iletchy. How did it all come about? 

The Metropolitan Bay Area of 1 ( J01 consisted of a San Francisco 
of 350,000 population, and a collection of small, quiet towns 
around the Bay. Booming growth, a high level of civic pride, 
and the belief of every citizen that San Francisco was to be 
the leading metropolis of the Pacific Coast were the keynotes 
of the times. 

Some dissatisfaction with the commercial supplier, the Spring 
Valley Water Company, prevailed, occasioned by high rates, 
periodic shortages and recurring water quality problems. That 
dissatisfaction had prompted language in the Charter enacted 
in 1900, setting as a goal the acquisition and construction of 
a municipally owned water supply system. What was needed was 
a plentiful, high-quality water source that would meet the 
area's need for at least 100 years. Looking east to the Sierra 
Nevada, the planners found such a source in Yosemite National 
Park. But the water was 150 miles away! 

The "City that knows how" was determined that the water system 
would be built, and the first land was purchased, and water 
rights established, in 1901. The ensuing struggle for permis- 
sion to build a dam in Hetch Iletchy valley went on for years. 
When the United States Congress confirmed the City's right to 
proceed in 1913, construction commenced on the largest such 
project on the Pacific Coast up to that time. After 21 years, 
and the expenditure of some $100 million, the first water 
arrived at Crystal Springs Reservoir via the Hetch Iletchy 
aqueduct in 1934. The drama surrounding the leadership, poli- 
tics, and the engineering and construction effort involved in 
the project would be worthy of an epic novel, as expansion of 
the system to meet water and power demand continues down to the 
present . 

The large and complex system was designed to be built in incre- 
ments as demand increased. The master plan concept of a full 
gravity aqueduct system to Crystal Springs, established in 1912, 
has been followed as the system has grown through the years to 
the present capacity of 300 million gallons daily. As a by- 
product of the falling water, hydroelectric generating capa- 
bility of 340 megawatts has been constructed; a major economic 
asset for San Francisco. Additional elements of the system are 
planned for construction as the demand increases. 



1 - 



Today, the benefits of the Hetch Iletchy project are so matter- 
of-factly accepted that the public has granted the system its 
highest accolade: cheap, pure and plentiful water is taken for 
granted! 



- 2 




The last concrete in the original 0' Shaughnessy Dam 
construction was poured in April, 1923, bringing the 
total to 398,000 cubic yards. The height of the dam 
was 226.5 feet above the original streambed and 344.5 
feet from the bottom of the foundation. It was 298 
feet thick at the base and 15 feet at the top. At the 
time it was constructed, it was the second highest dam 
in the United States, Arrowrock in Idaho winning by 
ten feet. Between 1934 and 1938 it was raised an 
additional 85.5 feet. 



HIGHLIGHTS 

Financially, the outcome of Hctch Hctchy's Water and Power 
system operation for 1975-70 was influenced by two major events 
which occurred during the year - one man-made and the other 
the result of a natural occurrence. 

Breakdown of wage negotiations for the upcoming fiscal year 
between City's crafts workers and the Board of Supervisors 
resulted in a 38-day strike by City employees including electri- 
cians, plumbers, carpenters, laborers, street cleaners, etc. 
who are members of the crafts union. The strike began March 
31, 1976 and ended on May 8, 1976. The public transit system 
was quickly brought to a halt when the Municipal Railway drivers 
joined the strike at the very outset. The importance of the 
Hetch Hetchy Water and Tower system operation to the success or 
failure of the strike was not to be overlooked. It, too, was 
forced to shut down with all hydroelectric generators stopping 
production at 1400 hours on April 2, followed by complete 
cessation of water delivery to the San Francisco Water Depart- 
ment for domestic purposes. 

The drought brought on by the lack of precipitation in the 
winter of 1975-76, resulting in the smallest snow melt runoff 
from the Hetch Hetchy, Cherry and Eleanor Watersheds in the 59 
years of record, has left the three reservoirs at less than 
60% full at the end of the report year. In order to conserve 
as much water as possible for domestic use in the Bay Area, the 
average daily power draft at Kirkwood and Moccasin Powerhouses 
beginning June 1, 1976, was reduced to 300 million gallons per 
day to coincide with the Hetch Hetchy Aqueduct capacity and the 
anticipated San Francisco Water Department demand for the next 
several months. In addition, the power draft at Holm Powerhouse 
was reduced to 200 cubic feet per second in order to conserve 
water at Lake Lloyd so that, if later conditions require, such 
water can be directed into the Hetch Hetchy Aqueduct. 



HETCH HETCHY ORGANIZATION AND FUNCTIONS 

Under policies established by the San Francisco Public Utilities 
Commission, the HETCI1 HETCHY WATER AND POWER DEPARTMENT and the 
BUREAU OP LIGHT, HEAT AND POWER serve the City and County of 
San Francisco in the dual function of operating department and 
service bureau. 

Iletch lletchy is a municipally-owned system of storage reservoirs 
and aqueducts which collects water from the Tuolumne River 
watershed and delivers it to the San Prancisco Water Department. 
As a by-product of falling water, Hetch Hetchy operates and 
maintains hydroelectric generating stations and high voltage 
transmission lines for the production and distribution of elec- 
tric energy. 

Through its Transit Power Division, Hetch Hetchy has funded, 
operated, maintained and provided improvements for the electric 
facilities of the San Prancisco Municipal Railway since July 1, 
1969. 

In order to handle this additional responsibility, Hetch Hetchy 
assumed control of the equipment and personnel of the Overhead 
Lines and Motive Power Sections of the Municipal Railway. 

All of Hetch Hetchy' s expenses, including those of the Transit 
Power Division, are supported by water and power revenues. 

The Bureau of Light, Heat and Power administers contracts for 
furnishing electric, gas and steam services to municipal depart- 
ments and handles monthly billings. It also administers con- 
tracts for furnishing street lighting services and for operation 
and maintenance of City-owned street lighting. Financing, 
design and construction of City-owned street lighting improve- 
ments are under the jurisdiction of the Department of Public 
W 7 orks, and plans for these improvements must be approved by the 
Public Utilities Commission through this Bureau. The Bureau is 
financed by appropriations from municipal departments and gas 
tax funds. 

For fiscal year 1975-76, the Department administered budgeted 
funds for all purposes as follows:

P LANS FOR THE NEAR F UTURE 

Plans for future Hotel) lletehy construction are included in the 
City's current Capital Improvement Plan. 

Projects which will be added next year will include the 
following : 

Cherry Eleanor Pumping Station 

We have studied the possibility of installing pumps at the 
Cherry end of the Cherry Eleanor Tunnel. This study determined 
that it was economically feasible to capture, for electrical 
generation, water which presently spills at Lake Eleanor during 
the runoff season. Preliminary design work will commence this 
year, while the necessary permits and approvals are being 
obtained. 

Moccasin Powerhouse Bypass 

Studies are planned to make improvements on Rattlesnake Creek 
and Rig Jackass Creek to permit the discharge of water from 
Priest Reservoir into the Hetch Hetchy Aqueduct for use in 
times of emergency when Moccasin Powerhouse is not operative. 



HETCH HETCHY WATER AND POWER SYSTEM 



REVENUE AND EXPENDITURES 



Revenue from Hetch Hetchy Water and Power operations is derived 
principally from two sources: 

1. Sale of electric power and energy to San Francisco Municipal 
departments, Modesto and Turlock Irrigation Districts in 
the San Joaquin Valley, and seven industrial customers. 

Kaiser Cement {j Gypsum Corporation Santa Clara County 

Kaiser Aluminum § Chemical Corporation Santa Clara County 

Lockheed Missiles and Space Company, Santa Clara County 

Inc. 

General Motors Corporation Alameda County 

IBM Corporation Santa Clara County 

Liquid Air, Inc. Alameda County 

Norris Industries, Riverbank Stanislaus County 

2. Sale of water to the San Francisco Water Department. 

POWER SALES 

Gross sale of electric energy amounted to $20,224,183, up from 
$18,484,718 during 1974-75. Although this revenue appears to 
be a new record, it does not have the same significance as the 
record revenue of last year. The reasons are not so obvious 
without knowing the following: 

(1) Much of the increase is due to the very large amount 
of supplementary power and energy which City had to 
purchase for resale and which was resold to the 
customers at substantially the same high price at 
which it was purchased. 

(2) The offset to last year's record revenue in terms of 
expenditure for supplementary power and energy was 
only $99,734, whereas this year the offset is 
$4,389,319. Therefore, from the standpoint of net 
earnings, the department finds itself in a much less 
profitable financial position than that of last year. 

Power and energy delivered to all City Departments increased 
1.91 over the previous year, mainly the result of increased 
consumption at the San Francisco General Hospital where addi- 
tional power for construction of the new facilities nearly 
doubled the total requirements of 11,091,942 kilowatthours for 
1974-75. Consumption at the Airport, usually the single largest 
energy consumer among the City departments, has remained sub- 
stantially the same as 1974-75. The requirements for the San 
Francisco Water Department have again increased 9.3%, reflecting 



more [lumping required by the drought condition. The Municipal 
Railway showed a decrease of 12.2% in annual consumption over 
the previous year, largely as a result of the Muni shutdown 
during the City employees' strike. 

Power and energy delivered to Modesto Irrigation District, 
Hetcli Metchy's largest power customer, and to Turlock Irrigation 
District, the third largest, increased by 17.71 and 13.6% 
respectively this year. These increases in purchases clearly 
reflect the dry year operation of the Districts' own plant where 
power is derived from water stored behind Don Pedro Dam. 

The hope of exceeding the record generation of 1974-75 was 
effectively shattered by the drought and the strike. Instead, 
the opposite was achieved with the lowest production recorded 
in seven years of operation of the present project. By 
comparison, the 1975-76 total output of 1,640,671,000 kilowatt- 
hours is 201 less than the record output of 2,057,609,000 
kilowatthours for 1974-75. 

Hetch Hetchy power is sold to City Departments at cost, repre- 
senting a saving to taxpayers for 1975-76 of approximately $3.2 
million compared to the cost if supplied by the local investor- 
owned utility. 

One of the benefits resulting from the June 24, 1975 Amendment 
Agreement witli the Pacific Cas and Electric Company for wheeling 
Hetch Hetchy power to City's municipal customers was the reduc- 
tion in energy which City has to supply to compensate the 
Company for losses incurred in transmission and distribution. 
The data for 1975-76 indicates that 33,248,681 kilowatthours 
was delivered to the Company for this purpose, almost 41,000,000 
kilowatthours less than that required under the old agreements. 
This reduction in losses when sold to industrial customers at 
prices effective during the year returned to the City additional 
revenue in excess of $650,000. 

In last year's annual report, it was estimated that the new 
electric power rates which were scheduled to go into effect 
July, 1975 would increase Hetch Hetchy' s power revenue for 1975- 
76 from sales to the municipal customers (including resale to 
Airport tenants) by one million dollars. Comparison of results 
for 1974-75 and 1975-76 has confirmed the accuracy of this 
prognostication. Another revision of the rates is scheduled 
for action by the Public Utilities Commission in July 1976. 
Adoption of the proposed rates will boost revenue from sales to 
private consumers and municipal users another $900,000 in the 
upcoming fiscal year. 

August 1975 marked the first month of higher rates for Hetch 
Hetchy power sold to the Modesto and Turlock Irrigation Districts 
under signed agreements with them dated May 22, 1973 and 
November 6, 1972 respectively.

OPERA TING AND MA INTENANCE - MOCCASIN DIVISION 

HOLM POWERHOUSE UNIT NO. 2 GENERATOR 

At approximately 0842 hours on Sunday, January 25, 1976, the 
13,800 volt stator winding of Generator No. 2 at Dion R. Holm 
Powerhouse failed. Preliminary investigation indicated that 
approximately 8 of the 216 coils had been damaged. However, 
detailed examination following removal of the rotor assembly 
disclosed that a total of 16 coils would have to be replaced. 
Several of these coils were still functional, but dc high 
voltage testing showed that they would probably fail in a short 
time and were therefore deemed unacceptable for continued use. 
Portions of insulation on 4 field poles were also damaged by 
hot metal splatters from the stator windings when the failure 
occurred, requiring re- insulat ion of the affected area. All 
repair work was performed by departmental personnel, with 
supervision provided by the field engineers from All is-Chalmers , 
the generator manufacturer. The repairs were completed and the 
generating unit returned to service by the middle of March. 

A board of inquiry consisting of the senior electrical engi- 
neer inc. staff members was formed to investigate the failure for 
cause and to recommend corrective measures. A final report is 
expected to include analyses and possible solutions to this 
maintenance problem whereby the reliability of the equipment 
can be improved. 

CHERRY DAM HOLLO W JET V ALVE REPAIRS 

The Machine Shop repaired one of the two 60 -inch valves used to 
release water from Lake Lloyd. The valve was leaking badly and 
water had gotten into the operating mechanism. If allowed to 
remain in place, it would have been necessary to replace the 
valve in a short period of time. It was necessary to build up 
and machine the body and plug seats, replace a brass bushing, 
a leather packing and two thrust bearings. Other miscellaneous 
repairs were made to broken or defective parts. The Mechanical 
Engineering Section provided engineering and procurement assis- 
tance to the Machine Shop, including inspection of work done to 
the plug seat by a local shop. At the end of the fiscal year, 
repairs were nearing completion and the valve will be available 
for use during the next runoff season. 

EARNER JOHNSON RE LI EF VALVE NO. 2 AT SAN JOAQUIN VALVE HOUSE 

The relief valve on Pipeline No. 2 at the San Joaquin Valve 
House was removed from service during pipe cleaning and painting 
(HH-511R). The machine shop used this time to completely 
rebuild the valve including braising and remachining the seats.

OPERATION AND MAINTENANCE - TRANSIT POWER DIVISION 

The Transit Tower Division is responsible for supplying the 600 
volt direct current power that is necessary to operate the 
streetcars and trolley coaches of the San Francisco Municipal 
Ra i Lway . 

The Transit Power Division is composed of two sections - the 
Motive Power Section and the Overhead Lines Section. 

Motive Power Section 



The Motive Power Section operates and maintains seven sub- 
stations which convert electric power from 12,000 volts 
alternating current to 600 volts direct current by means of 
motor-generators, synchronous converters, and mercury arc 
rectifiers. (See Appendix Table 3 for statistical data.) 
Motive Power is also responsible for maintaining the electric 
motors and associated control equipment for operating the 
cable-winding machinery located in the Cable Car Powerhouse at 
Washington and Mason Streets. In addition, Motive Power does 
periodic inspection, cleaning, adjusting and repairing the 
streetcar and trolley coach recorders at Central Control of the 
Municipal Railway. The substations operate 24 hours per day, 
36 5 days per year. 

In anticipation of the need to assume responsibility for eigh- 
teen new substations, this section perused and commented on the 
wiring and control schemes proposed for these stations. 

A new mimic board showing the new stations in schematic form 
was constructed and installed at the Bryant Substation. As new 
automatic stations are completed and become operational, they 
will be monitored and controlled from this remote location. 
Since Outer Mission and West Portal Stations are presently 
unmanned, controls for these stations were designed and 
installed on this new mimic board. This new status display 
and control board will continually be augmented with new 
automatic station controls until such time as it shall be super- 
seded by a more sophisticated and flexible Supervisory Control 
System. 

Overhead Lines Section 

The primary function of the Overhead Lines Section is to main- 
tain in satisfactory operating condition the trolley wire over- 
head facilities and the electric distribution system which 
conveys power to it. This electric distribution system consists 
of both overhead lines and underground cables. 



17 



Secondary functions include the maintenance of the Municipal 
Railway Signal Systems and the electric light and power systems 
of all Municipal Railway buildings. 

During the fiscal year 1975-76, the Overhead Lines Section 
responded to 3606 emergency calls. In addition to emergency 
calls, this section had a regular and extensive maintenance 
program for overhauling all overhead and underground facilities. 
This section operated with three shifts per day, seven days a 
week. Monday through Friday, the normal workday shift was from 
8:00 a.m. to 3:30 p.m. with a two-man emergency crew on the 
"swing" or evening shift (3:30 p.m. -10:30 p.m.) and the grave- 
yard shift (1:00 a.m. -8:00 a.m.). 

On Saturdays, Sundays and holidays a two-man emergency crew was 
available on each of the three eight-hour shifts; midnight to 
8:00 a.m., 8:00 a.m. to 4:00 p.m., and 4:00 p.m. to midnight. 
Overhead and underground facilities were systematically 
inspected, and worn or damaged parts were replaced before they 
could cause accidents or malfunction of equipment. 

A considerable amount of damage to overhead facilities was 
caused by trolley coaches de-wiring and snagging their poles in 
the overhead facilities and tearing them down, or by breaking 
the spans with the flaying poles. Such damage was repaired at 
no cost to the Municipal Railway. Other parties who damaged 
our facilities were billed for the cost of repairs. This 
included damage to overhead facilities caused by high loads on 
trucks or careless operation of crane equipment and damage to 
underground feeder cables by contractors digging into our duct 
lines. During 1975-76, responsible parties were billed for 7 
damage cases totalling $3,728.53. The Overhead Lines Section 
also performed work for building owners and contractors under 
work orders amounting to IS jobs totalling $44,183.13. This 
work included moving trolley poles to accommodate driveways; 
relocating trolley poles and feeders to permit construction of 
new buildings; temporarily removing trolley wires and feeders 
to permit passage of high loads: and shifting of trolley wires 
and feeders for various excavations. 

The Overhead Lines Section engaged in many other activities of 
a related nature which it is especially equipped to perform. 
These additional duties included repairs, maintenance and 
construction of electrical systems in Muni's car barns, offices 
and shops; welding and rebuilding of worn overhead lines special 
work; making and rebuilding parts for switches, warning block 
signals, car recorders, and strand alarms for the cable car 
system; installing mobile radio equipment; installing streetcar 
and bus stop signs and public information signs. 

In March 1976 the section curtailed operations for a six week 
period during a labor dispute involving city Craft workers.

ENG INEERING DIVISION 

The Engineering Division of Hetch Hetchy Water and Power provides 
engineering services for the Hetch Hetchy Project and the Transit 
Power Division. These services include the preparation of 
studies, reports, cost estimates, and plans and specifications 
for new construction, for replacement of structures and for items 
of major maintenance. Surveying, inspection of construction, 
contract administration and payment recommendations are provided 
for all construction work under Hetch Hetchy Water and Power. 
Work of unusual magnitude or which requires special knowledge 
and expertise is done by engineering consulting firms which have 
the necessary manpower and qualifications. The Engineering 
Division is organized into five main sections: Structural and 
Civil, Electrical, Mechanical, Architectural, and Construction.

BUREAU OF LIGHT, HEAT AND POWER 

S TREET LIGHTING 

General 

The lighting of public streets within the City of San Francisco 
is provided by facilities which are, on a City-wide basis, 43.5% 
owned by the City; 54. 7 o owned by the Pacific Gas and Electric 
Company; and a small percentage, 1.81, jointly owned. In the 
underground areas, where the economic advantage of City ownership 
is greatest, 81.31 of the lights are City-owned. Five years ago, 
the corresponding figure was 7 4.4%. 

In fiscal year 1933-34, the cost for street lighting was $1.25 
per capita; last year, with approximately thirty times as much 
light on the streets and public thoroughfares, the cost per 
capita was approximately $1.85. ~ 

Maintenance and repair of City-owned installations was performed 
under two contracts. One provided for group replacement of 
lamps in accordance with schedules developed by the Bureau. A 
second contract covered work required for repair of damaged and 
defective equipment, painting and miscellaneous maintenance. 

Under contract, the Pacific Gas and Electric Company furnished 
street lighting service as directed, including the furnishing, 
maintenance and operation of Company-owned facilities. Certain 
services were provided also for City-owned facilities, including 
switching and control, replacement of individual lamps and 
globes, and emergency work required during other than normal 
working hours. 

Electric energy for all City and Company-owned streetlight opera- 
tion was supplied by the Hetch Hetchy power system. 

Engineering 

The Bureau reviews, recommends changes, approvals or rejections 
of, and correlates all street lighting installations, including 
that done by the Department of Public Works, the Pacific Gas and 
Electric Company, the State of California, subdividers, etc. 

During the fiscal year 1975-76, 19 street lighting contracts, 
involving a total of 819 new streetlights, were approved by the 
Public Utilities Commission. Plans were submitted only after 
careful checking to determine that illumination will exceed the 
minimum requirements established by the American National 
Standards Institute; and that all materials used, and manner of 
installation, meet with the applicable local, state and federal 
rules, regulations and statutes governing the installation of 
electrical works.

BUREAU OF LIGHT, HEAT & POWER 
REVENUES AND EXPENDITURES 



FISCAL YEAR 1975-1976 



Operation and Maintenance 

As of June 30, 1976, a total of 37,378 City-owned and Company- 
owned streetlights were in service to the public streets, parks, 
viaducts, overcrossings , tunnels and underpasses. A summary of 
the number and type of units in service at the end of the fiscal 
year is shown in Appendix Table. 

A total of $1,326,226 was expended for operation, maintenance, 
and repair of the street lighting system. Of the total cost, 
$12,649 was paid by the State for its share of the operation and 
maintenance of street lighting at intersections on City streets, 
which are part of the State Highway system. 

During the fiscal year, there were 114 accidents involving damage 
to City-owned street lighting property. Investigation was made, 
as soon as possible, to remove hazards to the public and obstruc- 
tions to traffic. Total cost of repairs to damaged City-owned 
street lighting property was $73,125. Every effort was made to 
secure reimbursement for damages incurred from responsible 
parties. Previous experience indicates that approximately three- 
fourths of the repair costs will be recovered. 

Complaints 

During the year, 48 complaints requiring field investigation 
were received and acted upon. These complaints concerned 
inadequate illumination, objectionable glare in windows, and 
requests for temporary and permanent relocation of street 
lighting poles. 

Improvements 

During the fiscal year 1975-76, a total of 868 new City-owned 
streetlights were placed in service at a cost of $724,798. 
Improvements were financed by State Gasoline Tax and the 1964 
and 1972 Street Lighting Bond Issues as indicated in Appendix 
Tables 16 and 17.

UTILITY SERVICES TO MUNICIPAL DEPARTMENTS 

General 

Electric energy supplied to municiapl departments is generated 
on the Hetch Hetchy power system and delivered to various service 
points by transmission and distribution facilities of Pacific 
Gas and Electric Company under a wheeling contract. Natural gas 
supplied to municipal departments is furnished by the Pacific 
Gas and Electric Company under a service contract. 

Municipal Consumption of Electricity and Gas 

During the fiscal year, 486,936,786 kilowatthours of electrical 
energy were consumed through 1,054 municipal accounts at an 
expenditure of $6,077,738. Of the above, 147,463,469 kilowatt- 
hours of energy were supplied to the San Francisco International 
Airport for resale to tenants. Natural gas consumption was 
17,787,179 therms through 556 accounts at a cost of $2,691,890. 

There were several increases in gas rates last year which 
increased the cost to municipal accounts by approximately 
$805,652. The average cost per therm increased by approximately 
421. 

A summary of consumption and expenditures for these commodities 
is shewn in Tables 12 and 13.

for San Francisco. 




O'SHAUGHNESSY DAM AND HETCH HETCHY RESERVOIR 
showing the effects of the drought in February, 1977 



HIGHLIGHTS 

From the parched Redwood forests of the north state to the blazing 
deserts of the south, the one single aspect that dominated all of 
the water and power systems in California during the fiscal year 
is an unprecedented drought and its devastating impact. For the 
Hetch Hetchy Water and Power System, whose hydroelectric genera- 
tion is totally dependent on water, and whose viability as a going 
concern is principally dependent on power revenue, the year has 
been a particularly difficult one financially. 

The drought had its beginning in the winter of 1975-76 when lack 
of precipitation and meager snowmelt resulted in only 605,388 
acre-feet of runoff into Hetch Hetchy Reservoirs during the spring 
of 1976, or 53 percent of normal. The second dry year, 1976-77, 
resulted in even less runoff during the past spring, totaling only 
333,504 acre-feet, or 29 percent of normal. These record low 
inflows in successive years have left the three reservoirs in our 
mountain watersheds at less than 45 percent of capacity at the 
end of the report year. 



- 1 



Anticipating that the drought might continue into a second year, 
the Lower Cherry Aqueduct was reconditioned in the fall of 1976 
in the event that water supply to the Hetch Hetchy Aqueduct would 
need to be supplemented with water from Cherry Reservoir. This 
turned out to be a farsighted move when drought conditions dic- 
tated shutting down Dion R. Holm Powerhouse and diverting this 
water into the aqueduct to the Bay Area in October 1976. 

To further conserve water in our reservoirs against future public 
need, a request was submitted to the Secretary of the Interior, 
in March 1977, for permission to reduce fish releases from 
O'Shaughnessy Dam. So far, the Secretary has not advised us of 
any decision in the matter. 

Based on the precipitation record for the water year commencing 
October 1, 1976, and the result of snow surveys conducted on our 
mountain watersheds, the San Francisco Public Utilities Commission 
instituted a mandatory 25 percent reduction in system water 
consumption. The reduction was put into effect May 1, 1977, in 
order to insure the ability of the Hetch Hetchy systems to meet 
the needs of the San Francisco Water Department and its service 
area during the continuing drought. 

Comparing the amount of electric energy generated this year against 
that of previous years, the adverse impact of the drought is 
apparent. As generation was reduced to about 35 percent of normal, 
the resulting revenue available for supplying the cash flow for 
operating and maintaining the department was also reduced in 
roughly the same proportion. This necessitated rescinding many of 
the capital improvement projects scheduled for the year. 

In spite of the above, work progressed on the federally assisted 
Power Improvement Program for the rehabilitation of the Municipal 
Railway transit power system. As of the end of the fiscal year, 
approximately $26.5 million has been expended or encumbered. The 
professional services contracts for engineering design are 90 per- 
cent completed. Twenty-seven contracts for construction work and 
material purchases have been completed and twenty-two are currently 
in progress. Electrification of the Market Street Subway and Twin 
Peaks Tunnel is nearly completed. Ten of the eighteen substations 
are under construction, with three completed and in service. 
Thirty miles of the eventual fifty miles of underground duct lines 
are completed or under construction. Approximately 35 percent of 
the underground feeder cable has been installed, and an additional 
20 percent is on order for delivery to current installation 
contractors. The conversion of the streetcar overhead trolley 
system for pantograph operation is progressing with all work on 
the "K" Line under construction; the "N M Line ready for bid; and 
the "J", "L" and "M" Lines in the final design stages.

HETCH HETCHY ORGANIZATION AND FUNCTIONS 

Under policies established by the San Francisco Public Utilities 
Commission, the HETCH HETCHY WATER AND POWER DEPARTMENT and the 
BUREAU OF LIGHT, HEAT AND POWER serve the City and County of 
San Francisco in the dual function of operating department and 
service bureau. 

Hetch Hetchy is a municipally-owned system of storage reservoirs 
and aqueducts which collects water from the Tuolumne River water- 
shed and delivers it to the San Francisco Water Department. As 
a by-product of falling water, Hetch Hetchy operates and maintains 
hydroelectric generating stations and high voltage transmission 
lines for the production and distribution of electric energy. 

Through its Transit Power Division, Hetch Hetchy has funded, 
operated, maintained and provided improvements for the electric 
facilities of the San Francisco Municipal Railway since July 1, 
1969. 

In order to handle this additional responsibility, Hetch Hetchy 
assumed control of the equipment and personnel of the Overhead 
Lines and Motive Power Sections of the Municipal Railway. 

All of Hetch Hetchy' s expenses, including those of the Transit 
Power Division, are supported by water and power revenues. 

The Bureau of Light, Heat and Power administers contracts for 
furnishing electric, gas and steam services to municipal depart- 
ments and handles monthly billings. It also administers contracts 
for furnishing street lighting services and for operation and 
maintenance of City-owned street lighting. Financing, design and 
construction of City-owned street lighting improvements are under 
the jurisdiction of the Department of Public Works, and plans for 
these improvements must be approved by the Public Utilities 
Commission through this Bureau. The Bureau is financed by appro- 
priations from municipal departments and gas tax funds. 

For fiscal year 1976-77, the Department administered budgeted 
funds for all purposes as follows:

HETCH HETCHY WATER AND POWER SYSTEM 



REVENUE AND EXPENDITURES 



Revenue from Hetch Hetchy Water and Power operations is derived 
principally from two sources: 

1. Sale of water to the San Francisco Water Department 

2. Sale of electric power and energy to San Francisco Municipal 
departments, Modesto and Turlock Irrigation Districts in the 
San Joaquin Valley, and seven industrial customers: 

Kaiser Cement § Gypsum Corporation Santa Clara County 

Kaiser Aluminum § Chemical Corporation Santa Clara County 

Lockheed Missiles and Space Company, Inc. Santa Clara County 

General Motors Corporation Alameda County 

IBM Corporation Santa Clara County 

Liquid Air, Inc. Alameda County 

Norris Industries, Riverbank Stanislaus County 

WATER SALES 

This past year, revenue from the sale of water and standby service 
to the San Francisco Water Department was $8 million. 

POWER SALES 

Gross sale of electric energy was $43,341,973, up from $19,693,525 
during 1975-76. This doubling of revenue is deceiving, since the 
increase does not represent extra return on project investments 
for the following reasons: 

1. The increase is principally due to the record-breaking amount 
of supplementary power and energy which City had to purchase 
for resale, on account of the drought, and which was resold 

to the customers at substantially the same high price at which 
it was purchased. 

2. The offset to this year's so-called record revenue, in terms of 
expenditure for supplementary power and energy, is $33,921,500 
instead of the $2,100,000 budgeted, leaving only $9,420,473 in 
net revenue from gross, a far cry from the record net of over 
$18 million for 1974-75. 

Power and energy delivered to City Departments increased 2.0 per- 
cent over the previous year, about the same rate as in 1975-76. 
The City department mainly responsible for this increase is the 
San Francisco International Airport. Consumption at the Airport, 
the single largest energy consumer among the City Departments,

AND EXPENDITURES

has increased by 3.2 percent, indicative of a resurgence of 
construction and expansion activities. Requirements for the 
Municipal Railway appear to have increased by 9.5 percent over 
the previous year. This is not a valid comparison, of course, 
because of last year's low consumption due to shutdown of the 
public transportation system during the 38-day employees' strike. 

Power and energy delivered to Modesto Irrigation District, Hetch 
Hetchy's largest power customer, and to Turlock Irrigation District, 
the third largest, increased by 17.2 percent and 37.9 percent 
respectively this year. These increases are directly related to 
the drought. The storage in Don Pedro Reservoir, upon which the 
two Districts are dependent for generation and irrigation needs, 
has been going down steadily and the Districts have been extremely 
careful in using this precious and meager resource. Since Hetch 
Hetchy is in the same predicament, 86 percent of the power deliv- 
ered to the Districts by Hetch Hetchy had to be supplied from 
supplementary power and energy purchased from the Pacific Gas and 
Electric Company. 

Total generation of 710,002,000 kilowatthours for the report year 
from the project's three plants (the lowest production since 1969) 
amounts to 43 percent of the output of 1,640,471,000 kilowatthours 
in 1975-76. The financial strength of the Department resulting 
from this decline in electric energy generation has been severely 
impaired. If current conditions continue, additional shortfall 
in operating revenue in the upcoming fiscal year can be anticipated. 

Hetch Hetchy power is sold at cost to City Departments for munici- 
pal purposes, representing a saving to taxpayers for 1976-77 of 
approximately $4 million, compared to the cost if supplied by the 
local investor-owned utility at rates which include a "fuel cost 
adjustment" to account for the additional costs brought on by the 
unending price increases in oil, gas and coal fuel used for 
electric generation. Beginning September 1976, revised rates for 
Hetch Hetchy power, approved by the Commission on July 13, 1976, 
became effective for private consumers and municipal users. The 
higher rates boosted power revenue from these sources by nearly 
$1 million in the fiscal year. This is just another step in our 
continuing effort to base our power rates on the value of power 
in the market place, in order to maximize the return of the power 
that is produced from the Hetch Hetchy system. In a fiscal year 
where generation is at a record low, this increase helped to 
somewhat ease the economic dislocation brought on by the reduced 
generation. 

SYSTEM PLANNING 

As part of our efforts to increase rainfall in our mountain water- 
sheds, in light of the lessons learned from the drought, the

REVENUE FROM SALE OF ELECTRIC ENERGY 



Department has been investigating the feasibility of a weather 
modification program. The goal is to increase precipitation by 
cloud seeding of appropriate storms in the area. Preliminary 
data indicate that our effort should be directed to the Cherry 
Watershed. As an initial step to bring this program to fruition, 
plans are under way to hire expert consultants for the preparation 
of an Environmental Impact Report. 

On October 22, 1976, the City and County of San Francisco, through 
the Public Utilities Commission, together with the Modesto and 
Turlock Irrigation Districts, submitted an "Amended Application 
for Preliminary Permit, Clavey-Wards Ferry Project" to the Federal 
Power Commission. The application was made in order that the City 
and the Irrigation Districts might secure and maintain priority 
for a license under the Federal Power Act. The proposed project 
consists of three small dams and related facilities designed to 
harness the unused power potential of the Tuolumne. They would be 
situated on the upper reaches of the river below the City's Dion R. 
Holm and Robert C. Kirkwood Powerhouses and upstream from Don 
Pedro Dam. It is estimated that the project has a capability of 
generating 400 megawatts of power as well as a new water supply of 
11,900 acre-feet. However, actual development will depend on the 
outcome of a study by federal agencies for possible inclusion of 
this portion of the river in the federal wild and scenic river 
system. 

OPERATION AND MAINTENANCE 

On Sunday, November 7, 1976, at approximately 0822 hours, the 
13,800 volt metal-clad switchgear unit through which power is 
supplied to the 2,500 kVA Ridge Line transformer from Generator 
No. 2 at Dion R. Holm Powerhouse failed during routine testing 
of a protective device. The failure resulted in destruction of 
the circuit breaker element and related appurtenances. However, 
service to the Ridge Line was promptly restored by connecting it 
to the Mather Line, which is supplied from Robert C. Kirkwood 
Powerhouse. Necessary replacements were purchased from General 
Electric and installed by Department personnel with final adjust- 
ment and testing performed by field engineers from General 
Electric. All work was completed and service to the Ridge Line

OPERATION AND MAINTENANCE - TRANSIT POWER DIVISIO N 

The Transit Power Division is responsible for supplying the 600 
volt direct current power that is necessary to operate the street- 
cars and trolley coaches of the San Francisco Municipal Railway. 

The Transit Power Division is composed of two sections - the 
Motive Power Section and the Overhead Lines Section. 

Motive Power Section 

The Motive Power Section operates and maintains ten substations 
which convert electric power from 12,000 volts alternating current 
to 600 volts direct current by means of motor-generators, synchro- 
nous converters, mercury arc rectifiers and silicon rectifiers. 
(See Appendix Table 3 for statistical data.) Motive Power is 
also responsible for maintaining the electric motors and associated 
control equipment for operating the cable-winding machinery located 
in the Cable Car Powerhouse at Washington and Mason Streets. In 
addition, Motive Power periodically inspects, cleans, adjusts and 
repairs the streetcar and trolley coach headway recorders at 
Central Control of the Municipal Railway. The substations operate 
24 hours per day, 365 days per year. 

In anticipation of the need to assume responsibility for eighteen 
new substations being built by the Power Improvement Program 
(reported elsewhere in this report) , this section perused and 
commented on the wiring and control schemes proposed for these 
stations. The first of the new electrical substations, Civic 
Center Station, was placed in revenue service in December of 1976. 
A commissioning ceremony was held by Mayor George Moscone who 
dedicated this first station to the service of the citizens of 
San Francisco. 

A new mimic board showing the new stations in schematic form was 
constructed and installed at the Bryant Substation. As each new 
automatic station is completed and becomes operational, it will 
be monitored and controlled from this remote location via telephone 
lines. Since Civic Center, Church, Judah, Outer Mission and West 
Portal Stations are presently unmanned, controls for these stations 
were designed and installed on this new mimic board. This new 
status display and control board will continually be augmented 
with additional automatic station controls until such time as it 
shall be superseded by a more sophisticated and flexible Supervisory 
Control System. 

Overhead Lines Section 

The primary function of the Overhead Lines Section is to maintain 
in satisfactory operating condition the trolley wire overhead 
facilities and the electric distribution system which conveys 
power to it. This electric distribution system consists of both 
overhead lines and underground cables. 



-11- 



Secondary functions include the maintenance of the Municipal 
Railway Signal Systems and the electric light and power installa- 
tions at all Municipal Railway buildings. 

During fiscal year 1976-77, the Overhead Lines Section responded 
to 3,943 emergency calls, an increase of 8 percent over the prior 
year. In addition to emergency calls, this section performed a 
regular and extensive ongoing maintenance program. All overhead 
and underground facilities were systematically inspected and all 
worn or damaged parts that could cause accidents or equipment 
malfunctions were replaced. This section also operates an 
emergency crew 24 hours a day year round, including all holidays. 
The main work crew normally worked on the day shift but occasion- 
ally was assigned to night work to overhaul facilities during the 
hours Muni trolleys and streetcars do not run. 

A considerable amount of damage to overhead facilities was caused 
by trolley coaches de-wiring and snagging their poles in the 
overhead facilities and tearing them down, or by breaking the spans 
with the flaying poles. Such damage was repaired at no cost to 
the Municipal Railway. Other parties who damaged our facilities 
were billed for the cost of repairs. This included damage to 
overhead facilities caused by high loads on trucks or careless 
operation of crane equipment and damage to underground feeder 
cables by contractors digging into our duct lines. During 1976-77, 
responsible parties were billed for 9 damage cases totaling 
$17,246.41. The Overhead Lines Section also performed work for 
4 building owners and contractors under work orders amounting to 
$2,994.82. This work included moving trolley poles to accommodate 
driveways; relocating trolley poles and feeders to permit construc- 
tion of new buildings; temporarily removing trolley wires and 
feeders to permit passage of high loads; and shifting of trolley 
wires and feeders for various excavations. 

The Overhead Lines Section engaged in many other activities of a 
related nature which it is especially equipped to perform. These 
additional duties included repairs, maintenance and construction 
of electrical systems in Muni's car barns, offices and shops; 
welding and rebuilding of worn overhead lines special work; making 
and rebuilding parts for switches, warning block signals, car 
recorders, and strand alarms for the cable car system; installing 
mobile radio equipment; installing streetcar and bus stop signs 
and public information signs.

A package sewage treatment plant 
has been planned to replace the 
existing septic tank system. This 
process is a carryover from last 
year due to the lengthy process 
required to obtain approval for a 
federal "Clean Water Grant". State 
and federal permission to begin 
preparation of final plans and 
specifications was given in Septem- 
ber, 1976. Approval of the final 
plans and specifications was ob- 
tained in March, 1977. The con- 
struction contract has subsequently 
been awarded with work to begin in

HH-514 - Moccasin Administration Building, Replace Heating System 

Under this contract, completed during the year, the old heating 
system, using costly fuel oil, was replaced by a new electrical 
heating/ventilating system. In addition, extensive electrical 
improvements were made to bring the existing electrical system up 
to code requirements, and extensive plumbing and architectural 
improvements were also made. 

HH-549 - Bryant Substation and Power Control Center 

The Power Control Center (part of the Power Improvement Program 
described elsewhere in this report) was originally to be installed 
in the existing Bryant Substation building. When engineering 
investigations of this 1904 building revealed that it did not meet 
seismic standards, it was determined to construct a new building 
to house both the Control Center and the new substation. The 
Control Center portion of the building will accommodate the facili- 
ties for remote supervisory control of the eighteen new automatic 
substations that will provide electric power for the Municipal 
Railway. The design of the substation portion of the building 
was performed by our consultants under the Power Improvement 
Program. The design of the Power Control Center portion of the 
building has nearly been completed by Hetch Hetchy personnel. 
The design of the facility has received approval of the Art 
Commission and a City Planning Commission Environmental Impact 
Report determination of no significant effect on the environment. 

HH - 5 5 5 - Red Mountain Bar Surge Shaft Cover 

A construction contract was let to cover the surge shaft with a 
steel frame and steel sheets to provide a barrier against debris

A construction contract was let to prepare and paint trolley poles 
in numerous locations throughout the City. This work is part of 
a continuing program to rehabilitate all of the trolley poles in 
the City that are not to be replaced under the Power Improvement 
Program or other federal grant. 

HH - 5 6 5 - Lower Cherry Aqueduct Rehabilitation 

In anticipation of a continued drought, an emergency construction 
contract was let to rehabilitate the Lower Cherry Aqueduct in 
order to supplement the water supply to Hetch Hetchy Aqueduct with 
water from Lake Lloyd and Lake Eleanor. This three mile long 
aqueduct was originally constructed in 1917, had not been used 
since 1960, and was in poor condition. The contract has been 
completed and diversion of water began in November 1976 with a 
capability of supplying approximately 130 mgd into the Hetch 
Hetchy Aqueduct at Early Intake.

The City Planning Commission issued a negative declaration 
of environmental impact and approved the project as con- 
forming to the Master Plan. 

C) Equipment Purchase 

The substation equipment manufacturer, ITE-Gould, completed 
production on the $5,896,000 purchase contract. 

Review of shop drawings submitted by ITE-Gould was 
completed. 

Negotiations were conducted with ITE-Gould for a contract 
modification to provide additional equipment for Laguna 
Honda Substation. The second rectifier, transformer and 
related switchgear to be purchased will provide power 
reliability in the Twin Peaks Tunnel. This addition to 
the Project was approved by UMTA in the Grant Amendment. 

Deliveries of equipment under the purchase contract were 
virtually completed. Equipment for Laguna Honda, Judah 
and Downtown Substations were received by the Contractors, 
Herrero Brothers, Inc. (Laguna Honda and Judah) and DeNarde 
Construction Co. (Downtown) and is being installed. This 
completed delivery to the site for five substations. For 
the remaining substations, all items of the equipment, 
except for minor shortages, are on hand at the local ware- 
house for later pickup by the installation contractors. 

Meetings were held with factory representatives from ITE- 
Gould to resolve outstanding minor problems that have 
developed during installation and initial operation of 
the new substation equipment. 

The Service Engineer, assigned by ITE-Gould to assist 
during installation and testing of the new equipment, 
continued to provide assistance at Downtown, Civic Center, 
Church, Laguna Honda and Judah Substations. 

Work continued on the preparation of plans and specifica- 
tions for the purchase of additional substation equipment 
for Stations E, F, J and N.

BUREAU OF LIGHT, HEAT AND POWER 



STREET LIGHTING 



General 

The lighting of public streets within the City of San Francisco 
is provided by facilities which are, on a City-wide basis, 44.0 
percent owned by the City; 54.2 percent owned by the Pacific Gas 
and Electric Company; and a small percentage, 1.8 percent, jointly 
owned. In the underground areas, where the economic advantage of 
City ownership is greatest, 82.4 percent of the lights are City- 
owned. Five years ago, the corresponding figure was 78.3 percent. 

In fiscal year 1933-34, the cost for street lighting was $1.25 per 
capita; last year, with approximately thirty times as much light 
on the streets and public t horoughfares , the cost per capita was 
approximately $2.18. 

Maintenance and repair of City-owned installations was performed 
under two contracts. One provided for group replacement of lamps 
in accordance with schedules developed by the Bureau. A second 
contract covered work required for repair of damages and defective 
equipment, painting and miscellaneous maintenance. 



Under contract, the 
and Electric Company 
street lighting serv

Engineering 

The Bureau reviews, recommends changes, approvals or rejections 
of, and correlates all street lighting installations, including 
that done by the Department of Public Works, the Pacific Gas and 
Electric Company, the State of California, subdividers, etc. 

During the fiscal year 1976-77, 14 street lighting contracts, 
involving a total of 664 new streetlights, were approved by the 
Public Utilities Commission. Plans were submitted for approval 
. only after careful checking to determine that illumination will 
exceed the minimum requirements established by the American 
National Standards Institute; and that all materials used, and 
manner of installation, meet with the applicable local, state and 
federal rules, regulations and statutes governing the installation 
of electrical works. 

Operation and Maintenance 

As of June 30, 1977, a total of 37,446 City-owned and Company- 
owned streetlights were in service to the public streets, parks, 
viaducts, overcrossings , tunnels and underpasses. A summary of 
the number and type of units in service, at the end of the fiscal 
year, is shown in Appendix Table 14. 

A total of $1,524,286 was expended for operation, maintenance, 
and repair of the street lighting system. Of the total cost, 
$18,773 was paid by the State for its share of the operation and 
maintenance of street lighting at intersections on City streets, 
which are part of the State Highway system. 

During the fiscal year, there were 127 accidents involving damage 
to City-owned street lighting property. Investigation was made, 
as soon as possible, to remove hazards to the public and obstruc- 
tions to traffic. Total cost of repairs to damaged City-owned 
street lighting property was $104,000. Every effort was made to 
secure reimbursement for damages incurred from responsible parties. 
Previous experience indicates that more than half of the repair 
costs will be recovered. 

Complaints 

During the year, 40 complaints requiring field investigation were 
received and acted upon. These complaints concerned inadequate 
illumination, objectionable glare in windows, and requests for 
temporary and permanent relocation of street lighting poles. 

Improvements 

During the fiscal year 1976-77, a total of 691 new City-owned 
streetlights were placed in service at a cost of $1,184,878. 
Improvements were financed by State Gasoline Tax and the 1964 
and 1972 Street Lighting Bond Issue as indicated in Appendix 
Tables 16 and 17.
