摘 要：The U.S. Environmental Protection Agency (EPA), in accordance with the RE-Powering America's Land initiative, selected the Sky Park Landfill site in Eau Claire, Wisconsin, 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 Sky Park Landfill is a 26-acre site located on the southwest side of Eau Claire, Wisconsin, near Highway 37 and I-94. The site operated as a municipal waste facility from 1948 until closure in 1965. The present site is capped and unused, except for a small area used for excess snow and storm damage vegetation storage. A majority of the site has dense vegetation, including trees, which would need to be removed should the entire site be developed for a solar array. The site is located in an industrial district with adjacent manufacturing, offices, and municipal facilities. The feasibility of a PV system is highly impacted by the available area for an array, solar resource, distance to transmission lines, and distance to major roads. In addition, the operating status, ground conditions, and restrictions associated with redevelopment of a closed and capped landfill site can impact the feasibility of a PV system. Based on an assessment of these technical factors, the Sky Park Landfill is suitable for deployment of a large-scale PV system, should a reasonable power purchase agreement (PPA) be secured for the electricity produced.
