New York’s Energy Storage Site Could Power up to 20,000 Homes

NineDot Energy opened a large battery storage site in the Bronx, New York. Company leaders joined elected officials and community groups to cut the ribbon on a project replacing a former fuel oil trucking facility.

By the time next summer’s heat waves arrive, this setup will be fully ready. It will deliver almost 20 megawatts of power to the community, enough energy to power about 20,000 homes during the busiest times for the grid.

Addressing the Environmental Issues

For decades, Hunts Point residents have dealt with serious environmental issues. For example, local leaders say that more than 10,000 diesel trucks pass through the area daily. Additionally, two high-emissions “peaker” power plants operate nearby. These plants only run when the grid needs extra power, but they produce heavy pollution.

This new site stores energy and releases it during peak hours. This means older gas-fired plants won’t have to run as much, and eventually, they can be retired. It also provides reliable energy as the local produce market, fish market, and truck fleets switch to electric power.

“We’re honored to bring this battery storage site to the Hunts Point community,” said Adam Cohen, NineDot’s Chief Technology Officer and Co-founder. “Hunts Point has historically been overburdened by high-emitting fossil fuels, and this battery storage facility marks an inflection point in improving the local environment and grid reliability.”

Storing Energy for Years to Come

During the extreme heat wave from July 1 to 4, 2026, NineDot’s community batteries helped ease the strain on the electric grid. Across nine projects, they sent nearly 34 megawatts of power to Con Edison’s system when it was needed most. That is like taking 50,000 window air conditioners off the grid, or powering 34,000 homes for four hours a day.

NineDot currently has 11 operating projects across Staten Island and the Bronx, making it the largest battery fleet in Con Edison’s city territory. The company plans to hit 400 megawatts of battery storage by the end of 2026, with over 60 more projects already in the works.
