FarmFrench energy giant TotalEnergies, together with its partners, has formally taken the Final Investment Decision (FID) for the Mirny wind and energy storage project in Kazakhstan. With a total investment of approximately $1.2 billion, the project will build Central Asia’s largest integrated wind-plus-storage clean energy power station. It is reported that all 150 wind turbines required for the project will be supplied by Chinese enterprises.

Located in the Zhambyl Region of Kazakhstan, the Mirny project is planned with 1 GW of installed wind power capacity and supporting 300 MW/600 MWh battery energy storage system, making it a landmark large-scale new energy project in the region.

The project is led by Shanghai Electric Group as the general EPC contractor, jointly constructed with Shanghai Institute of Mechanical and Electrical Engineering and Kazakhstan’s local firm GCD Partner LLP. Construction is scheduled to start in 2026, with full-capacity grid connection and commissioning in 2029.

Media reports reveal that the project plans to procure 150 wind turbines, all to be delivered by Chinese wind turbine OEMs. Envision Energy will supply 124 units of 6.5 MW turbines, while Sany Renewable Energy will provide 26 units of 7.7 MW turbines. The large-scale supporting energy storage system will be supplied by Saft, a subsidiary of TotalEnergies.

Upon completion, the scheme will rank among Central Asia’s largest wind farms. It will generate 4 billion kWh of clean electricity annually, power around one million local residents, and cut carbon dioxide emissions by about 3.5 million tons per year.
