Pasadena’s largest city-owned solar photovoltaic project to date was officially connected to the municipal electric grid on May 31, 2011.
Pasadena Water and Power and Martifer Solar Inc. completed the 564-kilowatt rooftop solar system at Windsor Reservoir in Northwest Pasadena. It is comprised of 2,772 solar modules and estimated to generate 869,158 kilowatt hours of energy annually, or the equivalent power used by 100-125 average Pasadena homes.
The Windsor Solar Project will offset 100 percent of the annual electricity consumed by pumping activity at Windsor Well (which will become active in early July.)
“PWP pursued the Windsor Solar Project because it is a responsible solution – environmentally and fiscally – for managing the city’s vital water system infrastructure,” said Eric Klinkner, assistant general manager and chief deputy at PWP.
Funding for the project was made possible through federal tax incentives, rebates through PWP’s Pasadena Solar Initiative, and a 20-year power purchase agreement (PPA) with Spear Point Energy Green Lake Capital. Under the PPA, Spear Point Energy is responsible for the installation, operation and maintenance of the solar system, while PWP’s Water Division agrees to purchase the system’s energy output from Spear Point at a cost-efficient rate.
“The terms of the power purchase agreement will save the Water Division about $17,000 in electric charges per year,” Klinkner said.
“The solar system at Windsor Reservoir is one of the largest in Pasadena and represents our public utility’s commitment to helping us achieve local and statewide environmental goals,” said Pasadena Mayor Bill Bogaard.
The project fulfills four percent of the Pasadena Solar Initiative goal of installing14,000 kilowatts of solar power in Pasadena by 2017, which is PWP’s share of meeting the statewide solar goal of 3,000,000 kilowatts under California Senate Bill 1.
To date, PWP’s Pasadena Solar Initiative has committed more than $13 million to help fund nearly 300 customer-owned solar installations in Pasadena, for an aggregate solar capacity of 3,000 kilowatts.The Lamanda Park Branch Library and the Lake Avenue Metro Gold Line Station, like the Water Division, are also customers of PWP and have installed solar PV systems with program funding.
