Independent power producer Eolian has broken ground on the Flint Grid Project, a 200-megawatt battery energy storage system in Jersey Township, Licking County, Ohio, marking a significant milestone for grid-scale storage development in the region.

Project Scale and Configuration

The Flint Grid Project carries a total energy capacity of 1.06 gigawatt-hours, configured as a five-hour system — equivalent to a 5.3-hour discharge duration at full output. That combination of power capacity and energy storage volume positions it as the largest battery energy storage system built within the PJM Interconnection, the grid operator serving a large portion of the eastern United States. The project's scale reflects a growing trend toward longer-duration storage assets capable of providing sustained grid support rather than short bursts of peak shaving.

Regulatory and Siting Significance

Beyond its physical size, the Flint Grid Project carries a distinct regulatory distinction: it is the first grid-scale battery storage facility to receive a permit from the Ohio Power Siting Board. That approval represents a procedural landmark for the state, establishing a precedent for how large-scale storage projects navigate Ohio's siting review process. The permitting pathway cleared for Flint Grid could inform future applications as battery storage deployment accelerates across the Midwest.

Location and Load Context

The project is situated in Jersey Township within Licking County, northeast of Columbus. Notably, the site is adjacent to the New Albany data center corridor, an area that has seen substantial growth in high-density industrial and commercial load. Positioning a large storage asset near that kind of concentrated demand offers potential advantages for local grid reliability and load management, though the sources do not specify contractual arrangements between the project and any individual data center operators. The proximity to significant load centers in the Columbus metropolitan area underscores the strategic siting logic behind the project's location.

Broader Implications for PJM Storage

The Flint Grid Project's construction start arrives as grid operators and utilities across PJM continue to assess how battery storage can support reliability amid shifting generation mixes. A system of this capacity — capable of delivering 200 megawatts for more than five hours — can provide a range of grid services, including energy arbitrage, frequency regulation, and capacity contributions during peak demand periods. Eolian's project adds meaningfully to the storage pipeline within PJM at a time when the interconnection queue contains a growing volume of storage-only and hybrid applications. The project's completion would mark one of the more consequential storage additions to the mid-Atlantic and Midwest grid in the current development cycle.
