Eolian has started construction on the Flint Grid, a 200 MW / 1.06 GWh battery energy storage system near Columbus, Ohio, marking the largest battery project to clear the PJM 2027/28 capacity auction and the first grid-scale battery storage permitted by the Ohio Power Siting Board.

This Wire brief sits within Fusion42's coverage of Clean Energy.

◆ ◆ The Wire takeaway

Battery storage is shifting from pilot projects to grid-scale infrastructure in PJM, freeing up capacity critical for data centre expansion near Columbus. You should explore partnerships leveraging battery storage to access constrained markets where grid upgrades lag.
