Nov 3, 2025 (Solar Power World) – Distributed Energy Infrastructure (DEI) has completed a 7.1-MW solar + 4-MW battery storage project in Acton, Massachusetts, on a Superfund site formerly occupied by a chemical manufacturing facility.
DEI worked with Terrasmart to safely construct the system on the contaminated site. Excavation was minimized, with electrical infrastructure designed primarily aboveground to avoid disturbing contaminated soils. The system was designed around existing structures, including old concrete slabs, to reduce site disturbance.
