Former US landfill turned into 7 MW solar farm, cutting costs, emissions

Baltimore County, Maryland, has transformed a 213-acre former landfill site into a 7-megawatt solar farm featuring nearly 15,000 ground-mounted photovoltaic panels across four arrays. This installation is expected to generate approximately 8.2 million kilowatt-hours of clean electricity annually, meeting about 11% of the county government’s power needs. The project operates under a 25-year Power Purchase Agreement with TotalEnergies, which owns and manages the system, providing the county with a fixed electricity rate of 14 cents per kilowatt-hour. This arrangement offers long-term cost stability, reducing energy expenses for taxpayers while advancing Maryland’s sustainability and climate goals. Environmentally, the solar farm will significantly cut greenhouse gas emissions, equivalent to burning over 621,000 gallons of gasoline each year or offsetting emissions from driving more than 14 million miles in a gasoline-powered vehicle. The project exemplifies innovative land reuse by converting an idle landfill into a productive renewable energy resource, aligning economic efficiency
