NineDot Energy develops and operates community battery storage systems across the New York City metro area. The company also builds projects that connect to the local grid, aiming to support reliability while reducing reliance on fossil-fuel peaker plants.
The company completed its largest battery storage project so far in Hunts Point, The Bronx. NineDot held a ribbon-cutting event on September 23, joined by state and city officials, community organizations, and local advocates.
The site will supply close to 20 MW of power to the Hunts Point grid. NineDot says that output can cover roughly 20,000 homes during periods of peak demand. The company expects the system to be fully operational before next summer, when grid stress from heat waves typically peaks.
Hunts Point has dealt with heavy industrial traffic for decades. More than 10,000 diesel trucks pass through the area each day. Two high-emission peaker plants also operate nearby.
The new battery system occupies land once used by a fuel oil trucking company. Bronx Borough President Vanessa Gibson attended the event. She noted that NineDot cut the ribbon on its first Bronx site more than four years earlier, with this project marking a return to the same kind of milestone at a larger scale.
NineDot pointed to its performance during a heat wave in early July 2026 as an example of the technology's role during high-demand periods. Across nine of its battery projects, the company exported close to 34 MW during peak hours that week, supporting both Con Edison's local distribution system and the state transmission grid. NineDot compared that output to the equivalent of removing roughly 50,000 window air conditioners from the grid, or powering about 34,000 households for four hours a day during peak demand.
