In 2010, about 457 million people were online in China. At the end of 2011, there were 56 million new users. Having those large numbers of users, it is a must to have enough energy to power it all. It is no surprise that China now holds the world’s largest battery energy storage station located in ZHANGBEI, China. On September 20th, 2011 the company BYD announced the official opening of "China's Largest and First Environmentally-friendly Battery Storage Station.”
What makes China’s battery storage environmentally-friendly station different from the renewable generation systems is the gargantuan storage capacity. Renewable energy is not a continuous power source. The fact that energy comes in bursts, storage is essential in regulating the alternative energy sources. The station consists of a 140 Mega-Watts of renewable energy generation, 36 Mega-Watt-Hours (MWh) of energy storage, and a smart power transmission system. BYD outputs 1GW of solar a year, this new station will do wonders for regulation. It has shown to be a stable solution for transferring enormous amounts of renewable electricity safely to the grind on a scale.
All the credit to the design of the station goes to State Grid Corporation (SGCC). BYD played a big role by providing energy storage batteries in amounts that are larger than a football field. The batteries provide by BYD improves the renewable energy efficiency by 5%-10%. The total investment that was put into this station is worth over $500 million USD. The exact reason we do not see the same facility built elsewhere.
