Power
Generating clean energy for vital services.
Annual Report for the Fiscal Year Ending June 30, 2011
Since 1918, we have harnessed the kinetic energy of gravity-driven water as clean,
renewable hydroelectric power. Each year, the Hetch Hetchy Power System generates
approximately 1.7 billion kilowatt hours of green energy for vital services and facilities,
including San Francisco International Airport, San Francisco General Hospital, and the
Municipal Transportation Agency.
Revenue from energy sales allow us to lead the way with critical environmental initiatives
throughout the City. These initiatives are improving the energy-efficiency of City buildings,
increasing in-City renewable energy generation, and supporting San Francisco residents
as they pursue solar installations at home.
2010-11 Milestones
Concert Hall Upgraded for Symphony Centennial
Davies Symphony Hall’s heating, ventilation and
air-conditioning system were retrofitted this year
in time for the landmark San Francisco Symphony
Centennial. This project and other energy-efficiency
upgrades of municipal facilities are saving the City
more than 39,000 megawatt hours of electricity and
almost $4 million in energy costs each year.
EPA Green Power Leadership Award
We were one of two organizations nationwide to
receive a 2010 Green Power Leadership Award from
the U.S. Environmental Protection Agency (EPA)
for our commitment to reducing greenhouse
gas emissions.
Investing in Solar Power for Homes and Businesses
Over 400 San Francisco residents, small businesses
and nonprofit organizations installed solar rooftops
with the help of our solar incentive program,
GoSolarSF. In all, we issued $4.2 million in financial
incentives, funded exclusively by energy sales from
the Hetch Hetchy Power System. The new solar
arrays will help reduce greenhouse gas emissions
and generate more than 1.4 megawatts of clean,
locally-generated renewable energy.
New Energy-Efficient Lighting Coming to
City Streets
New light-emitting diode (LED) street lights have
replaced conventional lighting along four streets
in the South of Market area as part of the SOMA
Alleyway Improvement Project. The decorative,
contemporary fixtures are a prelude to ou ȁ
