The Gushanliang 1000 MW/4000 MWh standalone energy storage station, now the world's largest single-unit-capacity electrochemical energy storage facility, was recently connected to the power grid in Ordos. This milestone will help ensure the stable operation of the new-type power system and enhance regional energy security.

The project was invested and constructed by Inner Mongolia Zhongdian Energy Storage Technology Co, with a total investment of 3 billion yuan ($425.99 million). Construction began on June 28, and full capacity grid connection was achieved by December, completing in just over five months – a record-setting pace known as the "Dalad Banner Speed" for large-scale electrochemical storage projects.

Once operational, the station will supply approximately 1.2 billion kilowatt-hours of clean electricity to the grid annually, replacing 365,200 metric tons of standard coal and reducing carbon dioxide emissions by nearly 1 million tons. This will play a major role in advancing Dalad Banner's green development and help it to achieve the national "dual carbon" goals.

The Gushangliang 1,000 MW/4,000 MWh station is part of a larger complex comprising seven sub-projects under the broader Gushanliang Energy Storage Power Station initiative. Three additional sub-projects are rapidly advancing, expected to connect to the grid by the end of December. At that point, the total storage capacity will reach 2,300 MW/9,200 MWh, effectively addressing the instability of green power generation, and ensuring green power can be stored when abundant and supplied when needed.
