Prudent Energy Announces Installation of a MW Class VRB(TM) Energy Storage System for CEPRI

BEIJING, March 2, 2011 /PRNewswire-Asia/ -- Prudent Energy announced today it has finalized the installation of a 1MWh Vanadium Redox Battery (VRB™) energy storage system, sized at a rated power 500kW and a peak power of 750kW pulse capability for the China Electric Power Research Institute (CEPRI) in Zhangbei, Hebei province in northern China.

This project is part of the National Wind Power Integration Research and Test Center of China (NWIC) owned by State Grid Corporation of China, using 30 wind turbines with at least 78 MW of generating capacity, and 640 kW of solar photovoltaic (PV) capacity and 2.5MW of energy storage. Once completed, the testing center will be the largest such facility in the world and will represent a significant step forward for China's renewable energy development that includes clean energy storage.

The testing center will allow State Grid Corporation of China (the world's largest utility) to develop a combination of concepts for future grid operations ranging from renewable energy grid integration, to intelligent monitoring, communications and control ("smart grid"). Prudent Energy's VRB-ESS™ will be put to use at the NWIC to develop control algorithms for the effective integration of wind and solar power on the grid, leading the world in such efforts.

Prudent Energy is responsible for the design, engineering and commissioning of the VRB™ energy storage system, which is ready for handover this week. By pre-assembling individual modules of 175kW each and testing them prior to delivery, Prudent Energy was able to shorten on-site installation and commissioning time, while cutting cost and eliminating project risks.

"This project demonstrates how Prudent Energy's VRB™ energy storage technology helps to integrate renewable energy into power networks to ensure grid stability.  Rapid and deep cycling VRB energy storage technology has many advantages to qualify it as an essential component of the future grid," said Johnson Chiang, CEO of Prudent Energy.
