Hecate Grid’s Swiftsure Powers 500,000 Homes in NY11

Swiftsure is a grid-connected battery energy storage system under development in Staten Island, New York. Capable of storing up to 650-megawatts (MW) of power, Swiftsure will safely deliver clean, reliable energy to Staten Islanders.

The proposed project will provide up to 650 MW of clean power that meets New Yorkers’ energy needs without burning fossil fuels. Hecate Grid’s batteries charge from the grid when power demand is low and discharge energy back onto the grid when demand is high, helping to balance and stabilize the grid, keeping the lights on and AC running during extreme events.

Reliable Power for Staten Island: Swiftsure will be capable of storing enough energy to power 500,000 homes - more than the total number of residences on Staten Island. Our project will make sure that New York’s transition to a clean energy future doesn’t leave Staten Islanders behind, and provide the peak energy supply the borough needs to keep the lights on and the ACs running during heat waves.

Good, Local Jobs: Hecate Grid is committed to using union labor to build the Swiftsure facility, which will generate approximately 100 good-paying construction jobs. A Quiet, Clean, Safe Neighbor: Swiftsure is replacing a vacant lot currently used for parking and storage with a secure facility with minimal foot and vehicle traffic. The site will contribute to improved local air quality by replacing power normally generated by fossil fuel plants, and will use cutting edge, FDNY-approved fire safety technology.
