In January 2014, AES entered its sixth year of commercial service from advanced battery arrays.
Working with electric grid operators and utilities in the U.S. and Chile, AES has deployed and now operates and maintains a fleet of 174 MW of battery-based controllable resources. These resources play critical roles in grid reliability for customers by providing active grid balancing and reserves.
Whether in response to variations in wind output or to help support the unplanned outage of a transmission line, electric utility customers have been depending on AES designed grid battery arrays to monitor grid conditions and to dispatch accordingly 24x7 for more than five years.
Building on the commercial service record celebrated today, AES now offers utilities complete battery-based alternatives for resource adequacy and advanced reserves. Our most recent offering is a 4th-generation design incorporating learning from more than five years of deployment, operations, and maintenance experience.
In the development of its four successive designs of grid storage solutions, AES has had the opportunity to work with the following system operators and utilities: PJM Interconnection, New York ISO, ERCOT, California ISO, CDEC-SING, Indianapolis Power & Light, Dayton Power & Light, PECO, Southern California Edison, Centerpoint, and NYSEG.
