Braintree Landfill Solar: 1 MW Solar PV Facility on a Landfill in Braintree, Massachusetts

Braintree Landfill Solar is a 1 megawatt (MW) solar photovoltaic (PV) facility located in Braintree, Massachusetts, United States. The plant is owned and operated by Ameresco Inc and is currently operational, converting a former landfill site into a renewable energy asset. The facility uses solar PV technology to generate electricity, with a capacity of 1 MW, which is typical for a small-scale community solar project. Under the US regulatory framework, such projects benefit from the Inflation Reduction Act (IRA) and Massachusetts' Renewable Portfolio Standard (RPS), which incentivize solar development on underutilized land like landfills. By siting solar panels on a closed landfill, the project avoids land-use conflicts and contributes to local renewable energy goals. It supports grid integration of distributed solar and helps reduce greenhouse gas emissions, aligning with state and federal clean energy targets.

The facility is built on a capped landfill in Braintree, Massachusetts, a suburban area near Boston. This dual-use approach mitigates land-use impact by repurposing otherwise unusable land for clean energy generation. Solar PV on landfills avoids ecological disruption of greenfields and can help reduce local air pollution by displacing fossil fuel generation.
