AES plans to bring an additional 40 MW of energy storage resources to PJM Interconnection, which controls the power grid for 60 million people in the Northeast and Midwest regions of the U.S.
To be located at Dayton Power and Light’s (DP&L) Tait generating station, just south of Dayton, Ohio, the AES battery array will provide frequency regulation service to the PJM market and bring new energy technology to Ohio that is safe, reliable, does not bear direct emissions and does not require water. This facility is the first of its kind in the state.
This announcement comes on the heels of AES’ recent 400,000 MWh service milestone within PJM at its Laurel Mountain facility. When the Tait storage array comes online, which is expected to occur in September 2013, it will bring the company’s storage resources in PJM to more than 100 MW, all operating on AES’ patented control system, sOS.
This will be the third project within PJM to run on the software and the fifth overall. The PJM-specific module of sOS employs AES market expertise and PJM-specific operating experience to most efficiently control the array within the market’s unique dispatch model. This extensible AES sOS platform has been proven in multiple commercial settings and with multiple underlying battery technologies.
The 40 MW storage resource will consist of 24 MW from AES inventory with the remaining 16 MW coming from an existing AES facility, which the company is relocating to Ohio.
