TotalEnergies signed an investment agreement to develop a more than 1-gigawatt wind farm with a 600 megawatt-hour battery storage system in Kazakhstan, the company said in a news release Dec. 4, representing an investment of about $1.4 billion.

Called Mirny, the wind farm in Kazakhstan’s Zhambyl region would be the largest wind project for Kazakhstan, supplying more than 1 million people with electricity and avoiding the emission of 3.5 million tons of CO2 annually, TotalEnergies said.

“At COP28, more than 110 nations committed to tripling renewable energy capacity by 2030. TotalEnergies supports this call,” TotalEnergies’ CEO Patrick Pouyanné said in the release. “With this innovative wind and battery project, our company is making a direct contribution to this ambition and to the energy transition in Kazakhstan.”

The investment agreement comes about six months after TotalEnergies signed a 25-year power purchase agreement with the Financial Settlement Center of Renewable Energy, a public entity owned by the government of Kazahkstan, to supply power to the grid.

Mirny will be developed by TotalEnergies in partnership with the National Wealth Fund Samruk-Kazyna and the Kazakhstan’s national oil company KazMunayGas, which will each own a 20% stake in the project, TotalEnergies said.
