All-in BESS projects now cost just $125/kWh as of October 2025 2. With a $65/MWh LCOS, shifting half of daily solar generation overnight adds just $33/MWh to the cost of solar.
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.
As of recent data, the average cost of a BESS is approximately $400-$600 per kWh. Here's a simple breakdown: This estimation shows that while the battery itself is a significant cost, the other components collectively add up, making the total price tag substantial.
