REDP co-developed a 6 MW landfill-based PV facility for a Massachusetts municipality located on Cape Cod.  The project, which REDP developed with a major national EPC partner, will generate sufficient electricity to offset all of the electrical needs of the Town, its water department, and the regional school district at a substantial reduction in cost from current retail electricity rates.

The project is situated on a closed municipal landfill in an industrial zone far from residential areas, an ideal site for PV development. The project was designed using a ballasted racking system to preserve and protect the engineered landfill cap, and includes an innovative perimeter fence designed to allow the continued migration of local endangered turtles (protected under Massachusetts regulations) on to the landfill cap during nesting season.  The project includes over 21,000 PV modules arranged in rows over approximately 25 acres of the closed landfill.  The row spacing, module height and ballasted racking methodology were all designed to minimize or avoid landfill cap impacts, and to ensure that the grassed surface of the landfill continues to serve its dual function as a stormwater management system and as valuable habitat.

The project is interconnected to the local NSTAR distribution grid in a net metering configuration, and the electricity output is net metered for the benefit of the Town.  The project is eligible to participate in the Massachusetts Solar Renewable Portfolio Standard (SREC I), and is expected to generate over 7.2 million kilowatt hours of electricity annually, enough to satisfy the electricity needs of over 1,000 homes.

REDP was awarded the project after a competitive solicitation by the Town, and subsequently negotiated the terms of a land lease and power purchase agreement.  REDP secured all required permits for the project, including land use approval from the Town; interconnection approval from NSTAR; approval from the MA Natural Heritage and Endangered Species Program; approval from the MA Department of Environmental Protection; and SRPS eligibility from the Massachusetts Department of Energy Resources.
