China's first 100,000-kilowatt battery energy storage power station 18 in Zhenjiang, Jiangsu Province, was officially put into operation, which is equivalent to the urban power grid installed a large "rechargeable battery", opened a new stage of commercial operation of large-scale battery energy storage power stations in China.

This one container, is a storage battery, add up to a total of 101,000 kilowatts, the power stored here, equivalent to a 200,000 kilowatts of medium-sized power plant an hour of electricity, can meet the electricity needs of 170,000 households at the same time.

This large-scale urban power grid "charging treasure", only two months was built, can be charged in the low point of energy storage, power peak release of power, sudden failure to provide backup power. Can be such a large-scale energy storage battery centralized and efficient operation, in China for the first time, breaking through many scientific and technological challenges.

Jiangsu power grid spokesman, director of the Department of Development Wang Xu: It should be said that this is the country's first breakthrough in the 100,000 kilowatts of energy storage power station projects, unified access to the grid's "cloud energy storage" scheduling system of new technologies to achieve a decentralized construction, centralized scheduling control, for the safe and stable operation of our power grids to make enough support.

Large-scale storage of electricity for flexible and stable call has been the direction of the power system efforts. Previously, the more mature energy storage is pumped storage power station, but because of the long construction period, site requirements and other constraints, it is difficult to large-scale promotion. After years of exploration and practice, China's battery energy storage technology has made substantial progress, and now the cost has dropped significantly.

Secretary General of the National Technical Committee for Standardization of Electric Power Energy Storage Lai Xiaokang: It is expected that in the future, theli-ion batteryThe cost will also be reduced to $0.25 per kWh each time. And.New lithium-ion batteriesHas met the commercial operation of the required high temperature resistance, non-explosion and other safety needs, which are to open the construction of large-scale battery energy storage power plant, provides technical support.
