SHANGHAI, March 4, 2026/ CNW/– The Huai’an Salt Cavern Compressed Air Energy Storage (CAES) presentation task (the “Task”) in China’s Jiangsu Province, which is the world’s biggest CAES station, has actually just recently been totally commissioned. Shanghai Electric (SEHK:2727, SSE:601727) provided core devices for the Task, consisting of air turbine systems, generators, electrical motors, and molten salt tank.
The System 2 has actually effectively accomplished grid connection and full-load power generation at the very first effort, offering important engineering practice in assistance of China’s new-type power system advancement.
The Task includes 2 300 MW non‑supplementary combustion CAES systems, amounting to 600 MW of set up capability and 2,400 MWh of storage, with around 71% conversion performance. Air is compressed and kept in salt caverns throughout low‑demand durations, then launched to drive turbines for power generation at peak times, supporting grid stability through peak shaving and frequency guideline.
Using about 980,000 cubic meters of salt caverns situated 1,150 to 1,500 meters underground in Huai’an, the Task uses “molten salt + pressurized thermal water” non‑supplementary combustion high‑temperature adiabatic compression innovation. This allows compressed heat to be kept and recycled throughout the procedure without nonrenewable fuel source combustion, providing considerable low‑carbon advantages.
The very first 300 MW system reached full-load operation in December 2025, followed by System 2’s current commissioning. With an overall financial investment of $520 million, the totally functional station is anticipated to create 792 million kWh of electrical energy every year, that suffices to power around 600,000 families. It will conserve around 250,000 lots of basic coal and cut CO two emissions by 600,000 lots each year, providing a quantifiable effect on the area’s energy shift.
Shanghai Electric Power Generation Group provided core devices for the Task covering both power generation and thermal storage systems. The broad scope showcases Shanghai Electric’s incorporated engineering abilities in turbine equipment, power devices, and thermal storage, providing a reputable and replicable devices option for long-duration energy storage tasks worldwide.
As the world approaches carbon neutrality, long-duration energy storage innovations like CAES are crucial to boosting grid durability and making it possible for high‑penetration sustainable combination. Leveraging system combination knowledge from the Task, Shanghai Electric is advancing high‑end devices production and incorporated services to support the international energy shift and power system modernization.
