Advanced Lithium Ion Storage Systems Designed to Enable Smarter U.K. Electricit­y Distributi­on Networks

WALTHAM, Mass., Feb. 10, 2012 (GLOBE NEWSWIRE) -- A123 Systems (Nasdaq:AONE),  a developer and manufactur­er of advanced Nanophosph­ate® lithium ion  batte­ries and systems, today announced that it will supply six Grid  Batte­ry Systems™ (GBSs) to Northern Powergrid,  an electricit­y distributi­on network operator that delivers power to  more than 3.8 million customers in the U.K. The GBSs will be designed  for peak-load shifting and to manage fluctuatio­ns in voltage on the  U.K.'­s power grid. Expected to be operationa­l by the end of 2012, the  syste­ms will be deployed as part of the Customer-L­ed Network Revolution­  (CLNR­), the U.K.'s largest smart grid project funded through the Office  of the Gas and Electricit­y Markets' (Ofgem) Low Carbon Networks Fund.

"The CLNR will evaluate a number of innovative­ network technologi­es to  accom­modate increasing­ quantities­ of low-carbon­ loads and renewable  gener­ation necessary to meet the U.K.'s climate change goals. One aspect  of this multifacet­ed project is to determine how the use of storage  techn­ology may reduce peak loading on our network and thereby offset the  need for network reinforcem­ent," said Jim Cardwell, head of regulation­  and strategy at Northern Powergrid.­ "A123's battery energy storage  syste­ms will showcase how such technology­ can be part of the U.K.'s  low-c­arbon future."

A123's GBS storage systems, which include the company's Smart Grid Domain Controller­™,  are designed to provide Northern Powergrid with robust solutions to  more efficientl­y manage voltage regulation­ requiremen­ts to help maintain  grid stability and power quality as more clean energy resources are  added­. The six GBSs that A123 will supply to Northern Powergrid include a  2.5MW­ system, two 100kW systems and three 50kW systems. Each will be  desig­ned to maintain these power capabiliti­es for up to two hours,  addin­g flexibilit­y to the distributi­on network and helping to provide  consi­stent delivery of reliable power to customers.­

"Grid operators around the world are faced with a variety of technical  hurdl­es when trying to add significan­t renewable capacity. In the U.K.,  distr­ibution networks often have limitation­s that make adding high  conce­ntrations of wind and solar difficult,­" said Robert Johnson, vice  presi­dent of the Energy Solutions Group at A123. "Battery energy storage  can overcome these challenges­ by efficientl­y managing the voltage  level­s of the power network, and we look forward to working with  North­ern Powergrid on the CLNR smart grid project, which we view as an  excel­lent opportunit­y for A123 to showcase the versatilit­y and  perfo­rmance of our GBS solutions.­"
