A123 systems' advanced battery energy storage for renewable integration

This paper outlines A123's early ground breaking grid battery systems that are in commercial service today at multi-MW scale. Key characteristics of A123's Nanophosphate™ Li-ion battery are described. Then the current use of A123's MW-scale battery systems for Frequency Regulation is described. The paper then discusses how these characteristics and capabilities implemented in A123's current multi-MW scale battery systems will be extended and applied for renewable integration in two Government funded smart grid demonstration projects, 1) our Michigan funded Smart Grid Storage demo of PV integration with Detroit Edison and 2) our DoE funded Tehachapi Wind Integration project with Southern California Edison.
