As of most recent estimates, the cost of a BESS by MW is between $200,000 and $420,000, varying by location, system size, and market conditions. This translates to around $150 - $420 per kWh, though in some markets, prices have dropped as low as $120 - $140 per kWh.
The Project would include two new Project substations and two underground transmission lines, one at 115 kilovolts and one at 345 kV, to connect the BESS with the nearby Eversource Substation #250 (Mystic Substation) located at 173 Alford Street, Boston.
Cost range overview: Installed BESS for residential-scale systems typically falls in the $7,000-$30,000 band, with per-kilowatt-hour prices commonly around $1,000-$1,500 depending on chemistry and vendor.
Deploying a battery energy storage system (BESS) offers a smart, future-ready solution to these challenges. Store electricity during off-peak hours and discharge during peak times to reduce your energy bill by 20–40% annually through energy arbitrage.
