GSA Northwest Arctic Region Completes Second PV System

April 1, 2002

Partnering with DOE, the General Services Administration's (GSA) Northwest Arctic Region installed and commissioned a 10-kilowatt photovoltaic (PV) system at the Federal Building and U.S. Post Office in Wenatchee, Washington. DOE provided funding for the study and the design of the project, and GSA funded the purchase and installation of the solar panels and ancillary equipment. The GSA Wenatchee PV project supports the Planet GSA program, the Million Solar Roofs Initiative, and Executive Order 13123.

GSA's Wenatchee PV system features an array of 132 polycrystalline solar panels manufactured by BP Solar and a Xantrex Technologies 3-phase voltage inverter. The 2x4-foot solar panels each generate approximately 70 to 75�watts each of electricity. "This project demonstrates GSA's commitment to the environment. Clean energy and cost effective alternatives such as PV are more important than ever," said Robin Graf, GSA, Assistant Regional Administrator for Public Buildings Service.

Another feature of the project is GSA's participation in the Chelan County Public Utility District's Sustainable Natural Alternative Power (SNAP) generation program. Under the District's SNAP program, GSA will receive up to $1.20 credit towards its electricity account for every kilowatt of capacity generated by its PV system for the next 10�years.

Graf noted, "In addition to the economic benefit of the project, the environmental benefits are enormous." The system will generate more than 400 megawatthours of electricity over the next 25 years and reduce emissions by 390,650 lbs. of carbon dioxide; 357 lbs. of sulfur dioxide; and 100�lbs. of nitrogen oxide. GSA will collaborate with Bonneville Power Authority (BPA) to monitor and publish the performance of the system.

The GSA Wenatchee PV project is GSA Northwest Arctic Region's second PV project. In 2000, GSA partnered with BPA, DOE Seattle Regional Office, WesternSUN, and others, to install a 2-kilowatt PV system on the rooftop of GSA's Building Blocks Daycare Center. The daycare center located next to GSA's Regional Headquarters in Auburn, Washington, will generate 60 megawatthours of electricity over the next 25 years.
