AES Reaches More Than 100 MW of Grid-Scale Storage in the U.S.

The AES Corp. is now operating more than 100 MW of grid-scale storage resources with the commercial operation of its 40 MW resource in Ohio. Located at Dayton Power and Light’s Tait generating station in Moraine, Ohio, the project is providing fast-response frequency regulation services to PJM Interconnection to stabilize the grid that serves more than 60 million people.

"At AES we are dedicated to improving lives by providing safe, reliable and sustainable energy solutions," said Andres Gluski, President and CEO, AES. "We are pleased to increase our presence in Ohio with the addition of 40MW of Advanced Energy Storage at DP&L's Tait Generation Station."

The facility is the largest of its kind in Ohio and helps to meet the needs otherwise provided by power generation from inefficient or retiring power plants, reducing overall system emissions and water use while optimizing existing grid resources.

This is AES’ fifth facility to run on its Storage Operating System. This patented operating system, called sOS, is a fast-response control architecture that applies patented performance algorithms to automate the operation of AES-delivered battery-based energy storage arrays, optimizing performance and efficiency for customers, and extending the life of the battery.

The Tait battery array includes more than 800,000 battery cells and connects through DP&L Tait station’s transformers, operated by DP&L and DPL Energy, LLC, through an independent agreement with PJM. The project was deployed from AES’ inventory of battery modules allowing for engineering, construction, and commissioning to occur in less than nine months.

With the operation of this facility, AES has more than 174 MW of grid-scale, power plant equivalent flexibility resources in operation. AES storage resources are currently deployed in the United States and South America.
