Landfill Solar Project

South Portland's one-megawatt solar array at the City’s capped landfill (929 Highland Avenue) came online in October 2017. This is the largest municipal solar project in Maine to date. Portland-based ReVision Energy installed the 2,944 photovoltaic panels on the 34-acre former landfill, which is behind the City’s transfer station and new public services facility. The solar array is expected to generate 1.2 million kilowatt-hours of energy per year, roughly 12% of the electricity used by South Portland’s municipal and school buildings.
