The plant, CTG’s first independent energy storage power station, will ensure the reliable green power supply in Qingyun County, Shandong Province. It is CTG’s first independent energy storage power station, using the world’s most advanced 1500-volt liquid-cooled lithium iron phosphate energy storage technology with a design loss of only 15%.

The project is designed to have a total capacity of 300 MW/600 MWh (i.e., a maximum charge-discharge power of 300 MW and a total storage capacity of 600 MWh). The storage capacity is equivalent to one hour’s output from a power plant with an installed capacity of 600,000 kilowatts.

The project comprises three phases. In the first phase, a 100 MW/200 MWh energy storage system and a 220 KV booster station will be constructed. This setup can store 200,000 kWh of clean electricity in a single charge, significantly enhancing the overall utilization of renewable energy resources and bolstering the safe and stable operation of the power grid. It successfully initiated emergency start-ups and achieved peak power generation during crucial events, including the Beijing Winter Olympics, Winter Paralympics, summer peak electricity consumption, and peak winter periods, fulfilling its primary role as an energy supply guarantee for power storage projects.
