Grid stability battery systems for renewable energy success

A123 Systems (A123) has deployed over 20 MW's of Nanophosphate™ battery-based systems that are currently providing Ancillary Services in wholesale electric markets. Ancillary Services include Frequency Regulation and Spinning Reserves. This paper outlines A123's early ground breaking grid battery systems. It describes their characteristics and the applications that these energy storage systems are used for today. The paper then discusses how these characteristics and capabilities implemented in A123's current multi-MW scale battery systems can be extended and applied to support increased delivery of clean renewable energy while maintaining reliable and secure grid performance.
