Windsor Reservoir Solar Project | Pasadena, California
In 2011, PWP installed a 0.564 MW rooftop photovoltaic solar project atop the PWP Water Division's Windsor Reservoir. The project generates approximately 872 MWh annually and the renewable energy generated is purchased by the Power Division through bill credits to the Water Division thereby reducing PWP's customers' water bills. These savings benefit PWP's water customers through reduced operating costs of the Water Division.


Milford Wind Corridor Phase | Milford, Utah
The City entered into a power sales agreement with the Southern California Public Power Authority (SCPPA) for 2.5% (approximately 5 MW) of the output (including capacity, energy and associated environmental attributes) of Milford Wind Corridor Phase I Project, a 203.5 MW nameplate capacity wind farm comprised of 97 wind turbines located near Milford, Utah. The facility went into commercial operation in 2009.



High Winds Generation Facility | Solano County, California
In 2003, the City Council approved a 25-year power sales agreement with SCPPA for the purchase of wind-powered electrical energy associated with a 6 MW (or approximately 17,500 MWh per year) share of the PPM Energy, Inc. (now Iberdrola Renewables ("Iberdrola")) High Winds wind generation facility. The High Winds Project is a 145.6 MW wind generation facility located in Solano County, California.




Azusa Hydroelectric Plant | Azusa, California
The Azusa Hydroelectric Plant is a 3 MW hydroelectric plant located in the San Gabriel River Basin. Energy is accumulated and delivered to the City by Southern California Edison through an agreement which provides for deliveries at rates up to 15 MWh. The Azusa Hydroelectric Plant has historically delivered approximately 3 GWh of energy to the City annually for the past 15 years. Generation in recent years has decreased to minimal volumes due to regional drought conditions. In August 2013, PWP completed the seismic retrofit of the penstock and by-pass pipe making these structures compliant with current seismic code.


Hoover Uprating Hydroelectric Project Interest | Black Canyon, Nevada
The City has two cost-based power purchase agreements with the United States Department of Energy Western Area Power Administration for a combined total of up to 20 MW capacity from the generating units at the hydroelectric power plant of the Boulder Canyon Project at Hoover Dam (the "Hoover Project"), located approximately 25 miles from Las Vegas on the Nevada/Arizona border. The City's capacity entitlement is comprised of an 11 MW renewal contract and a contract for 9 MW resulting from the uprating of the Hoover Project. The actual capacity available from the Hoover Project varies, depending on hydrologic conditions, maintenance scheduling and other outages. Under normal hydrologic conditions, the City receives approximately 60 GWh of annual energy deliveries.


Puente Hills Landfill Gas-to-Energy | Whittier, California
In 2014, the City Council approved a 14-year power sales agreement with SCPPA for approximately 30% of the output from the Puente Hills landfill gas-to-energy project, starting January 1, 2017. The Puente Hills project is an existing 43 MW project located near Whittier, California.




Chiquita Canyon Landfill Gas-to-Energy | Valencia, California
In 2004, the City Council approved a 20-year power sales agreement with SCPPA for the purchase of 8.3 MW of landfill gas-generated electrical energy from the Ameresco, LLC, Chiquita Canyon Landfill Gas to Electricity generation project located in Valencia, California. The project began operation in 2010.


Heber South Geothermal Project | Imperial Valley, California
In 2005, the City Council approved a 25-year power sales agreement with SCPPA for the purchase of 2.1 MW of geothermal-generated electrical energy from the Ormat geothermal generating project, producing approximately 17,500 MWh per year. The Ormat geothermal project is located in the service area of the Imperial Irrigation District and the energy is delivered to the California Independent System Operator over the IID transmission system.


Powerex Renewable Energy Contract | Washington State and British Columbia
In 2016, the City Council approved a four-year contract with Canadian firm Powerex Corp. for the purchase of 17,500 MWh per year of Category 1 and 35,000 MWh per year of Category 2 bundled renewable energy and Renewable Energy Credits beginning January 1, 2017. The products will be supplied from Powerex's existing fleet of California Renewable Portfolio Standard-certified renewable resources in British Columbia and Washington State.

SCPPA Palo Verde Nuclear Generating Station | Tonopah, Arizona
The City has contracted with SCPPA for a 9.9 MW (4.4%) entitlement of 225 MW SCPPA Palo Verde Nuclear Generating Station. This resource provides the City with approximately 65-75 GWh of baseload energy annually.
