A123 Systems to Provide 11-MW Grid Battery System for Auwahi Wind Project

LCG, December 27, 2011--A123 Systems announced Thursday that it will supply an 11-MW Grid Battery System (GBS) to Sempra Generation. The GBS will complement Sempra's Auwahi Wind project in Maui, Hawaii and help to regulate and smooth intermittent wind power generation, thereby providing grid stability for Maui Electric company.

A spokesperson for A123 stated, "We believe that wind-rich locations like Hawaii represent a significant opportunity for energy storage, especially as project developers and utilities continue to understand that storage has the capability to help maximize production and reduce the challenges associated with the variability of wind power generation. We consider Sempra Generation's selection of our GBS energy storage solution for the Auwahi Wind project to be strong validation of our technology, and we look forward to showcasing the benefits of our energy storage systems for wind power integration when the Auwahi project is operational."

The Auwahi Wind project includes eight wind turbines, with a combined electric generating capacity of 21 MW. The storage system will use A123's proprietary Nanophosphate lithium ion batteries and built-in power electronics to deliver up to 11 MW of power in milliseconds. The project also includes A123's Smart Grid Domain Controller to manage voltage regulation requirements for the project. Construction is expected to begin early next year, with commercial operation to commence by the end of 2012.

Last June the Hawaii Public Utilities Commission approved a 20-year contract for Maui Electric Company to purchase electricity from Sempra Generation's Auwahi Wind project. Hawaii has a clean energy goal of obtaining 40 percent of its electricity from renewable sources by 2030.
