Feasibility Study of Economics and Performance of Solar Photovoltaics at the Snohomish County Cathcart Landfill Site in Snohomish County, Washington. A Study Prepared in Partnership with the Environmental Protection Agency for the RE-Powering America's La

摘要

The U.S. Environmental Protection Agency (EPA), in accordance with the RE-Powering America's Land Initiative, selected the Snohomish County Cathcart Landfill site in Snohomish County, Washington, for a feasibility study of renewable energy production. The National Renewable Energy Laboratory (NREL) provided technical assistance for this project. The purpose of this report is to assess the site for a possible photovoltaic (PV) system installation and estimate the cost, performance, and site impacts of different PV options. In addition, the report recommends financing options that could assist in the implementation of a PV system at the site. This study did not assess environmental conditions at the site. The Snohomish County Landfill is a municipal landfill that was built in 1980 and was a state-of-the-art facility when it was built. The landfill was closed in 1992 and was capped shortly thereafter. A leachate collection system and landfill gas extraction system were installed at the site. The main contaminants include metals, ammonia nitrogen, chlorine, and sodium. Snohomish County is interested in hosting a PV system on its capped landfill at the Cathcart Way Operations Center to generate clean, renewable energy.
