China has announced the completion of what it says is surely the world’s largest battery energy storage station.
Built adjacent to a 140 MW wind- and solar energy project in Zhangbei, Hebei Province, the $500 million storage station consists of battery array that will provide up to 36 MW of storage.
In a written statement, BYD, the China-based technology giant that worked with the State Grid Corporation of China (SGCC) on the project, said the combination of wind, solar and storage technology will increase the energy efficiency realized by the facility by as much as 10 percent.
SGCC said it chose BYD’s Iron-Phosphate battery technology because of its superior service life (over 20 years) and also used BYD’s “peak shaving & load leveling” charge and discharge methodologies.
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 $500 million.
“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.”
He Long, Vice President of BYD, said, “BYD is honored to cooperate with China and SGCC to build this large energy storage station and to make a contribution in the utilization of renewable energy resources.”
