AES Corp. (NYSE: AES) has reached the 100 MW mark for grid-scale storage resources with the commercial operation of its 40-MW resource in Moraine, Ohio. The project, at Dayton Power & Lightâs Tait Generation Station, provides fast-response frequency regulation services to PJM Interconnection to help stabilize the power grid.
The new storage facility is the largest of its kind in Ohio and helps meet the needs otherwise provided by power generation from inefficient or retiring power plants, the company stated in a release.
The 40-MW facility is the fifth facility by AES to run on its storage operating system, called sOS. The system is a fast-response control architecture that automates the operation of AES-delivered battery-based energy storage arrays.
The Tait battery array includes more than 800,000 battery cells and connects through the stationâs transformers, operated by DP&L and DPL Energy LLC, through an independent agreement with PJM.
