Construction of the Rochi Energy Storage Project in Angren District of Uzbekistan is now underway.
Invested and built by China Gezhouba Group Overseas Investment Co., Ltd., a subsidiary of China Energy Engineering Group Co., Ltd (Energy China), the project is the largest electrochemical energy storage project invested by a Chinese enterprise overseas.
It is also the first foreign-invested grid-side electrochemical energy storage project in Uzbekistan and the first overseas energy storage investment project of Energy China.
With a planned total investment of $140 million, the project covers an area of about six hectares (90 mu).
Based on lithium iron phosphate battery cells, the electrochemical energy storage project is equipped with a 150 MW/300 MWh energy storage system and is connected to the 220-kilovolt Rochi transformer substation through a newly-built 220-kV boosting station and a 6.1-kilometer 220-kV double-circuit transmission line.
The project is scheduled to be put into commercial operation in December 2024.
During the construction period, it is expected to provide more than 300 jobs for local people.
Once operational, it is expected to provide a power regulation capacity of 2.19 billion kilowatt-hours, ensuring a more stable, secure, and sufficient power supply of the country and boosting economic growth in affected areas and improving local livelihood.
