20-Year-Old Closed Landfill in Massachusetts Now Powering 400 Homes With Solar


Waste Management, in partnership with project owner Captona Partners, recently completed construction on a 2.5-MW solar farm at the closed MT Sullivan Landfill in Massachusetts.

Closed since 1998, the landfill now contains 7,938 solar panels on over 6 acres of land.  The 2.5-MW capacity generates enough energy to power 400 homes in the region.

“Solar farms require a lot of area, and closed landfills make excellent sites for them,” said Chris DeSantis, Area Vice President, Waste Management. “Waste Management has developed similar projects at other closed facilities across the country.  We are pleased to add MT Sullivan, which is now one of four closed landfill sites in Massachusetts that are generating renewable, solar energy.”

Two additional sites–Hudson/Stow Landfill in Hudson, Massachusetts (5 MW) and Berkley Landfill in Berkley, Massachusetts (3.6 MW)–were also developed by Captona Partners while the fourth site–Hunt Road LF in Amesbury, Massachusetts (4.5 MW)–was developed by Citizens Energy Corporation.

Collectively, the four solar farms generate enough energy to power approximately 3,000 Massachusetts homes.

“We are excited to create additional, long-term value for the closed landfill by supplying clean energy to the area’s residents and businesses,” said Roshni Mali, Director from Captona Partners, and project manager for the Hudson/Stow, Berkley, and Chicopee solar projects.
