Capped Rhode Island Landfill Adds 5.74 MW of Solar Power to Grid

Why It Matters

The project proves that underutilized landfill sites can be economically viable renewable energy hubs, boosting regional clean‑energy capacity and municipal revenues.

Key Takeaways

• 5.74 MW solar installed on capped Coventry Landfill
• Project yields approx. $4.4 M town revenue during lease
• Converts underutilized CERCLA site into clean‑energy asset
• Strengthens Ameresco‑Luminace partnership in New England
• Supports local job creation and energy resiliency

Pulse Analysis

Landfill‑to‑solar conversions are gaining traction as utilities and developers seek low‑cost, low‑impact sites for new capacity. The Coventry Landfill, already sealed under CERCLA regulations, offered a ready‑made, non‑contiguous parcel that avoided the permitting hurdles of greenfield development. By layering photovoltaic panels atop the cap, Ameresco and Luminace demonstrated how environmental remediation can dovetail with renewable‑energy goals, delivering power without additional land disturbance.

Beyond the environmental upside, the project delivers a tangible fiscal boost to the Town of Coventry. The $4.4 million estimate includes lease payments, property taxes and reimbursements for cap maintenance, creating a steady revenue stream that can fund municipal services or further sustainability initiatives. Construction and ongoing operations have also generated short‑term jobs and will require local maintenance staff, reinforcing the economic multiplier effect often cited in community‑scale solar projects.

Strategically, the venture deepens the Ameresco‑Luminace alliance, positioning both firms as leaders in New England’s burgeoning solar market. Their collaboration leverages Ameresco’s project‑development expertise with Luminace’s asset‑ownership platform, accelerating deployment across the region’s limited developable land. As states push for higher renewable targets, similar brownfield projects are likely to become a cornerstone of capacity planning, offering a replicable model that balances energy security, environmental stewardship, and local economic growth.
