State regulators in New Jersey have selected a large battery storage project in Bergen County to participate in a program aimed at strengthening grid reliability as electricity demand rises across the region.

The New Jersey Board of Public Utilities chose the project as part of the Garden State Energy Storage Program, an initiative launched in 2025 to support the deployment of 2,000 megawatts of energy storage capacity by 2030.

Elevate Renewables is developing the Garden State Reliability Project, a 150-megawatt / 600-megawatt-hour battery storage facility at the Bergen Generating Station in Ridgefield, New Jersey.

The existing power plant, a 1.2-gigawatt natural-gas facility, has served Bergen County, New Jersey for decades, and Alpha Generation manages it. Both companies receive backing from infrastructure investor ArcLight Capital Partners.

Battery storage systems store electricity when supply is plentiful and release it during periods of higher demand. Market participants increasingly use this technology to address short-term supply constraints in regions such as the PJM Interconnection, which operates the regional grid serving parts of the Mid-Atlantic and Midwest.

$200M Investment Supports Grid and Jobs

Developers say the Garden State project could provide enough electricity during peak demand periods to supply more than 100,000 homes. Elevate estimates the development represents roughly $200 million in private investment. And could create about 50 union construction jobs at peak activity.

The project would be built on the site of an existing power plant, allowing developers to use established transmission infrastructure while avoiding development on undeveloped land.

Elevate has been expanding its battery storage portfolio in the PJM region. In January the company acquired the Prospect Power Storage project in Rockingham County, Virginia, a 150-MW / 600-MWh battery facility currently under construction near Northern Virginia’s data-center corridor. The project is expected to begin operations in mid-2026.

Across the United States, states are increasingly building large‑scale battery storage systems to strengthen their power grids and manage rising electricity demand. In Texas, local officials have given the green light to Spearmint Energy’s 300‑megawatt Red Egret Battery Storage Project, a utility‑scale system designed to improve grid flexibility and stability, with construction expected to begin soon. Developers and utilities nationwide view battery storage as a key tool for addressing peak load challenges.
