Carlisle Energy Services Inc. (CES) announced in an Aug. 24 press release that its Spectro PowerCap exposed geomembrane solar cover (EGSC) system in Madison County, N.Y., is completed.
The release said it is expected to be interconnected and fully operational within a month. Consulting engineer of record, Barton & Loguidice, submitted, and the New York Department of Environmental Conservation permitted, the installation as a 20- to 30-year long-term interim cover.
The eight-acre demonstration system features Carlisle’s GeoTPO geomembrane, with a south-facing 40kWp, DC-integrated solar photovoltaic array powered by Uni-Solar, according to the release.
The Madison County landfill is the first municipal landfill in the country to apply this technology in a closure project, the press release stated. Future plans for the site, referred to as the Madison County Agriculture and Renewable Energy Park, include a one-megawatt landfill gas system that captures the heat generated by the turbine engines to dry lumber on-site and to heat the building.
Other on-site green energy programs are under consideration, such as the possibility of adding a windmill, hydroponic greenhouses, and an additional solar array.
“The photovoltaic landfill cover will play an integral role in Madison County’s growing renewable energy initiative, and we are proud to demonstrate the technical and commercial feasibility of Carlisle’s unique landfill closure system,” said James Zecca, Madison County’s Solid Waste Department director.
Carlisle’s cover system features a three-ply, scrim-reinforced geomembrane that serves as both the closure system and platform for integrated solar photovoltaics. The press release said it was developed for exposed geomembrane cap applications as both a long-term and final landfill closure solution.
