Huadian (Haixi) New Energy Co., a subsidiary of China Huadian Group, has efficiently accomplished the full-capacity grid connection of the Togdjog Shared Energy Storage Station in a chilly, high-altitude area of China. This milestone marks the beginning of operations for China’s largest electrochemical storage facility.
The Delingha challenge, Haixi prefecture, Qinghai province, is situated at an altitude of greater than 3,000 meters. The challenge boasts an influence output of 270 MW and a complete storage capability of 1,080 MWh. It is split into eight storage areas and 56 storage items. At full operation, it’s anticipated to offer roughly 300 GWh of fresh vitality yearly.
The facility options out of doors prefabricated lithium iron phosphate (LiFePO4) battery storage methods, supplied by Chinese storage system provider Sungrow. The firm has put in 51 items of its Power Titan liquid-cooled storage system. In addition, an experimental zinc-bromine stream battery storage system has been put in, though its capability has but to be decided.
Zinc-bromine stream batteries, a extra mature expertise within the stream battery class, provide an vitality density three to 5 instances better than lead-acid batteries and attain 10-20% of the price of lithium-based storage batteries. The set up goals to check the efficiency of zinc-bromine battery storage methods at excessive altitude, massive wind-solar-storage vitality bases.
The new Togdjog Shared Energy Storage Station will complement Huadian’s 1 GW solar-storage challenge base and three MW hydrogen manufacturing challenge in Delingha, making it not solely the biggest electrochemical storage challenge in China but in addition the biggest sensible shared vitality storage station constructed and operational. in chilly and excessive areas.
