Installation and Ongoing O&M, Landfill-Mounted 275 kW Thin Film Solar Photovoltaic System

Sovereign provided operation of a solar PV system at a closed landfill in Gloucester County, NJ on behalf of the property owner and former operator of a 125-acre, 2.8 million barrel capacity former terminal. Our team provided construction management and solar energy services for the construction and installation of a 275 kW ground mounted solar array, the largest at that time on the east coast, consisting of a 5,880-panel photovoltaic (PV) panels that powers the site's groundwater treatment system. The system uses solar energy to operate six recovery wells including pump motors, aerators, and blowers; that transfer extracted groundwater into a biologically activated carbon treatment system, at a rate of approximately 300 gallons per minute (gpm).

The PV solar system supplies 350,000 kilowatt hours (kWh) of electricity each year, meeting 20-25% of the groundwater system's energy demand. Since the system is grid tied, additional energy can be provided for remaining electrical requirements from the grid. Use of the PV system prevents 571,000 pounds of CO2, 1,600 pounds of SO2, and 1,100 pounds of NOx emissions from reaching the atmosphere each year. Of 15 sites studied in an EPA-funded paper, "Green Remediation and the Use of Renewable Energy Sources for Remediation Projects," the site was the largest producer of renewable energy supplied completely and directly to a remediation system
