For Ohio, the Tait project brings a multi-million dollar investment in a cutting-edge technology that can displace power generation from inefficient or retiring plants, reduce overall system emissions, and create construction jobs and tax revenue in the Dayton region.
With this storage array in particular, AES is leveraging the mobility and scalability inherent in battery-based grid resources to quickly deploy resources that rapidly meet the needs of any given market. 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.
“We’ve designed our business model in a way that allows us to quickly evaluate and respond to changing market needs,” said Chris Shelton, President, AES Energy Storage. “We can make decisions on where we locate battery storage to optimize service across markets. Physically moving an asset to where it’s needed most hasn’t been possible with traditional power generation and load resources, so it’s exciting to be able to do this with energy storage assets.”
The DP&L Tait station’s generating turbines, operated by DP&L and DPL Energy, LLC, are used during times of peak electricity demand in the summer. The new project will connect through the station but will have an independent agreement with PJM. Unlike conventional resources, the Tait battery facility does not require water to operate and will not produce direct emissions.
The new array will bring AES’ total energy storage fleet to 174 MW of power plant equivalent flexibility resource, serving customers in the United States and South America
