On November 5, the Shanghai Electric Golmud Meiman Minhang 32MW/64MWh energy storage station in Golmud, Qinghai province officially went into operation. The project features battery systems installed in two cargo sheds in a warehouse style. The system stores renewable energy during periods of high wind or solar curtailment and transfers the stored electricity to the grid when needed. It can provide effective power smoothing and enhance the quality of renewable power generation.
The first phase of the project consists of a 32MW/64MWh energy storage system. Shanghai Electric Gotion New Energy Technology Co. has provided the lithium-ion battery system, while EPC has been provided by Shanghai Electric New Energy Co. The energy storage station is connected to the local Qinghai grid, reducing solar and wind curtailment for nearby renewable power plants. The project is part of the new “shared energy storage” model which allows it to be shared among multiple renewable energy station owners, thereby increasing investment returns, and serving as an innovative pilot for the promotion of greater renewable energy penetration.
