On December 30th, 2011 BYD Company Ltd. (Shenzhen, China) and the State Grid Corporation of China (Beijing, China) announced that they have completed construction on 36 MWh of energy storage to accompany 100 MW of wind and 40 MW of solar photovoltaic (PV) generation in Zhangbei, Hebei Province, China.

The companies estimate that there are no energy storage systems to accompany renewable energy generation of this scale in operation anywhere in the world. The USD 500 million project uses iron-phosphate battery technology, as well as BYD charge and discharge technology.

"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 China National Energy Administration Deputy Director Xiu Binglin.

"This State Grid project demonstrates a solution and will be the model of development for China’s new energy resources."

Solution to improve RE efficiency by 5-10%

BYD estimates that their solution for energy storage with a smart grid improves renewable energy efficiency by 5% - 10%.

The company has embarked on a number of similar MW-scale projects with China Southern Power Grid Company Ltd. (Guangzhou, China).
