Eolian Begins Construction on 200 MW, 1.06 GWh Flint Grid Battery in Ohio

The project cleared PJM capacity auctions after winning Ohio Power Siting Board approval, signaling new routes for battery revenue and local grid relief.

Announced 30 July, the news comes one day after independent power producer (IPP) Eolian began construction on the Flint Grid battery storage project in Licking County (New Albany is primarily located in Franklin County, with a small portion extending into Licking County)—a 200MW/1.06GWh facility located next to New Albany data centre and industrial loads.

Overview

  • Construction started the week of July 29 on Flint Grid, a 200 MW battery energy storage system with roughly 1.06 GWh of capacity sited in Jersey Township near New Albany data‑centre and industrial loads.
  • Eolian says the system will deliver about five hours of energy and expects commercial operation before PJM’s 2027–28 capacity year, making it the largest BESS to clear that auction.
  • The Ohio Power Siting Board granted the project a permit and PJM accredited Flint Grid in the 2027/28 Residual Capacity Auction, giving the developer a key revenue and market‑qualification milestone.
  • A separate nearby deal announced July 30 named Veolia operator of a 350 MW microgrid with 430 MWh of storage for an AI data‑centre campus, illustrating developers’ turn to on‑site generation to speed delivery and reliability.
  • Eolian has not confirmed final supplier, battery chemistry, or total cost beyond saying the build will require hundreds of millions of dollars, a disclosure gap that matters for project lifespan, financing and local grid planning.
