This is an energy storage project with a capacity of 54MWh installed in a large industrial customer's facility in Jiangsu. The project includes a 110kV dedicated substation for the customer, with a total transformer capacity of over 60,000KVA. The energy storage system consists of 20 sets of 2.7MWh containerized batteries, with a total investment of approximately 89 million yuan. The project is connected to the grid at 10kV, and the peak-valley price differential is the main source of benefits. Since its operation in 2020, there have been no safety accidents and it has been running stably and reliably.
