# Eolian Builds Ohio Grid Battery

Eolian is constructing the Flint Grid battery project in Jersey Township, Ohio, near Columbus. Designed to deliver 200 MW for more than five hours—over 1 GWh—the project is described as the largest battery project built within the 13-state PJM grid. It reflects growing demand for grid-scale storage near data-center and industrial loads, but the signal identifies no solicitation, contract value, or procurement contact.

- Suppliers of battery systems, grid interconnection, and related construction services can use the project as an indicator of demand for large-scale storage in the PJM market.
- Because Flint Grid is already under construction and no procurement opportunity is specified, businesses should distinguish this project from an open bid and assess future opportunities across the broader PJM storage pipeline.
