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.

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.

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.

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.

2. Electrification Project
A) Design Services
Preliminary design reports, covering the modifications
to the existing streetcar trolley overhead wiring to
permit pantograph operation and the installation of
feeder cables, gap breaker stations and trolley wire
systems in the Market Street Subway and the Twin Peaks
and Sunset Tunnels, were reviewed with the consultant,
PBQ5D, Inc. and Gibbs § Hill, Inc., and were accepted,
with revisions to be incorporated into the final design.
The consultant began work on final design contract plans
and specifications.
Contract plans and specifications for Contract HH-521,
Market Street Subway Electrification, Embarcadero Station
to Duboce Portal, were completed and transmitted to UMTA
for approval. Bids were received on May 15, 1975. The
contract was awarded on May 27, 1975 to Amelco Electric,
San Francisco, California, who submitted the low bid of
$1,077,000. The contract was certified by the City
Controller on June 30, 1975. Work is scheduled to
commence early in July 1975.
A decision was made to combine the Twin Peaks Tunnel

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.

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.

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.

FISCAL YEAR 1974-75
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
W7orks, 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:

PLANS FOR THE NEAR FUTURE
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.

OPERATING AND MAINTENANCE - 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 HOLLOW JET VALVE 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.

The old Moccasin Powerhouse completed June, 1925.
The new Moccasin Powerhouse completed May 20, 1969,
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.

ENGINEERING 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.
During the year, plans and specifications were prepared for the
following work to facilitate and maintain Hetch Hetchy operations
[IH-454 - Reconstruct Moccasin Sewage Disposal System.
A package sewage treatment plant producing an odorless effluent
and sludge has been planned to replace the existing septic tank
system. This project is a carryover from last year due to the
slowness to acquire approval for the Federal "Clean Water Grant"
which we reapplied for last year. Conceptual approval has been
received. The EIR and the Project Report received approval from
the State Water Resources Control Board, and we are now awaiting
Federal EPA approval. The Hughes site for the effluent sprinkler
field was purchased during the year.
HH-477 - Moccasin Penstock Valve House.
A contract was let for the construction of a steel frame struc-
ture to enclose the butterfly valves at the head of Moccasin
Penstock. This structure will provide protection and security
for the valves.
HH- 511R - San Joaquin Pipeline No. 2, Repair Lining.
A contract was let for cleaning the interior of the pipe and
applying a coal-tar lining. This work was necessary because
the existing cement mortar lining, which protects the steel pipe
from corrosion, has been softened by action of the soft water
and the invert is being eroded away.
HH-512 - San Joaquin River Valve House, Repairs and Piping.
Under this contract, which was completed during the year, new
sump pumps and related piping were installed at the San Joaquin
River Valve House. Also, under this contract, a leaking manifold
at the valve house was repaired.

steam heating system and bring ihe electrical service at the
building up to code were completed and bids opened this year.
The existing heating system had become expensive to maintain
and operate because of its age and its use of fuel oil. The
replacement of the oil by electric heating necessitated increas-
ing the capacity of the building electrical system, and improv-
ing it to meet code requirements.
IIH-539 - Repair and Taint Concrete Trolley Poles (Van Ness
Avenue) .
A contract has been let to repair and paint concrete trolley
poles on Van Ness Avenue. This work is part of a program to

Street) .
Contract plans and specifications have been completed to
replace, repair and paint steel trolley poles on Mission Street.
The contract is scheduled to start in September 1976. This
work is part of a continuing program to rehabilitate all trolley
poles in the City.
HH - 5 5 4 - Construction of #47 Trolley Coach Loop at Army Street.
At the request of the Municipal Railway, a contract was let to
restore the terminal loop of the #47 trolley coach line to Army
Street. Several years ago the route was shorted to turn back
at 25th Street in order to facilitate the construction of the
freeway interchange at Army Street and Potrero Avenue. The
Department of Public Works funded the project.
HH- 5 56 - Claribel Lateral Timber Bridge.
A contract was let for the construction of a timber bridge to
replace an existing wood plank bridge across the Oakdale
Irrigation District's lateral that has collapsed. The bridge
provides access for maintenance and inspection along our right-
of-way.

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, 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.

This report is respectfully dedicated to
Hetch Hetchy employees, past and present,
whose devoted and conscientious efforts
have made possible these accomplishments
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 "NM 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,

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.

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
reverted to Dion R. Holm Powerhouse on June 3, 1977.

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 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.

Moccasin Sewage Treatment
Plant
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
August, 19 77.

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
entering the water supply.
HH-557 - Paint Steel Trolley Poles, Various Locations
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

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 thoroughfares , 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

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.

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, 496,305,458 kilowatthours of electrical
energy were consumed through 1,072 municipal accounts at an
expenditure of $6,966,586. Of the above, 152,161,432 kilowatt-
hours of energy were supplied to the San Francisco International
Airport for resale to tenants. Natural gas consumption was
17,174,388 therms through 560 accounts at a cost of $3,321,758.
There were several increases in gas rates last year which
increased the cost to municipal accounts by approximately
$629,868. The average cost per therm increased by approximately
28 percent.
A summary of consumption and expenditures for these commodities
is shown in Tables 12 and 13.
