China’s revolutionary new storage battery for renewable energy

China’s State Grid and BYD Launch World’s Largest Battery Energy Storage Station, Market Watch .  ZHANGBEI, China, Dec 30, 2011 (BUSINESS WIRE) — BYD and the State Grid Corporation of China (SGCC) have finished construction on what may be the world’s largest battery energy storage station.

This large utility-scale project, located in Zhangbei, Hebei Province, combines 140 Mega-Watts of renewable energy generation (both wind & solar), 36 Mega-Watt-Hours (MWh) of energy storage and a smart power transmission system. While there are renewable generation systems of this scale in service today, there are no battery systems of this size.

The State Grid system is demonstrating a stable solution for transferring vast amounts of
renewable electricity safely to the grid on an unprecedented scale. Although BYD manufactures 1GW of solar panels annually, their role in this project was primarily providing energy storage batteries in arrays larger than a football field…. This new project with the
State Grid has outpaced other grid projects in China and, though independently designed by SGCC, is part of the national “Golden Sun” program. The first phase investment with 100MW of Wind, 40MW of Solar and 36MWh of Battery is worth over $500M USD (~3.3 Billion RMB).

“The large-scale implementation of clean and green energy, such as
wind and solar power, can only be realized when the technical
difficulties of this new energy application in the utility system are
resolved,” said Xiu Binglin, Deputy Director of the National Energy
Administration. “This State Grid project demonstrates a solution and
will be the model of development for China’s new energy resources.”

BYD’s battery energy storage system provides a solution for the
realization of energy storage in the smart grid that improves
renewable energy efficiency by 5%-10%….
