Planned at the Bergen Generating Station in Ridgefield, the 150-megawatt, 600-megawatt-hour system—also referred to as Two Rivers Storage—will be integrated into an existing natural gas facility. Co-locating storage with established infrastructure allows developers to bypass some of the land-use and permitting hurdles tied to greenfield projects while accelerating timelines.
New Jersey’s grid is facing mounting pressure from several directions: increasing electricity demand, the phase-out of older generation assets, and tightening conditions in PJM Interconnection’s capacity market. Recent auctions have reflected these constraints, with prices trending upward as available supply narrows.
Battery storage is being positioned as a practical response. Compared to traditional generation, storage assets can be deployed more quickly and placed in locations that directly address congestion. The Garden State Reliability Project is expected to supply enough power for more than 100,000 homes during peak periods, offering a buffer when demand surges.
State policy is aligning around this approach. Launched in 2025, the GSESP targets 2,000 megawatts of storage by 2030, with the goal of improving system flexibility while keeping long-term costs in check. Regulators increasingly see storage as a tool to stabilize both reliability and pricing in a tightening market.
The project will operate within PJM’s competitive market, where storage must balance reliability with economic performance. Batteries typically charge during periods of lower demand and discharge when prices rise, helping to smooth volatility and increase available capacity.
This capability is becoming more relevant as ratepayers face upward pressure from constrained supply. Additional flexible capacity can reduce reliance on higher-cost peaking resources and moderate price spikes, though outcomes will depend on how effectively storage integrates into market operations.
Backed by ArcLight Capital Partners, the roughly $200 million investment highlights the role of private capital in scaling grid infrastructure. It also reflects a growing alignment between policy frameworks and market incentives aimed at accelerating storage deployment.
Siting the project at the 1.2-gigawatt Bergen Generating Station underscores a broader industry trend: leveraging existing assets to move faster. Established interconnections and infrastructure can shorten development cycles and limit environmental disruption, while co-location may improve operational efficiency.
Beyond grid impacts, the project is expected to generate local economic activity, including construction employment and incremental tax revenue. More broadly, investments in grid reliability are increasingly tied to economic competitiveness, particularly as energy-intensive sectors continue to expand.
As New Jersey works toward its storage targets, the Garden State Reliability Project offers an early example of how policy, infrastructure strategy, and market forces are intersecting. Its performance will likely serve as a reference point for future storage deployments across the region.
