TotalEnergies has approved a major renewable energy investment in Central Asia, taking the final investment decision and securing financing for the Mirny onshore wind and Battery Energy Storage System (BESS) project in Kazakhstan.
The US$1.2 billion development, located in the country’s southeast, is set to become one of Kazakhstan’s largest renewable energy initiatives, combining one gigawatt of wind capacity with 600 MWh of battery storage.
Once operational, the Mirny project is expected to generate approximately 100 TWh of renewable electricity over 25 years — enough to supply around one million people.
The electricity will be sold to the Government of Kazakhstan under a 25-year Power Purchase Agreement signed in 2023, providing long-term revenue certainty and supporting the country’s transition toward cleaner energy.
The project will reach full capacity in 2029 and represents a significant step toward Kazakhstan’s goal of increasing the share of renewables in electricity generation to 15 per cent by 2030.
In addition to expanding generation capacity, Mirny is designed to strengthen grid reliability through the integration of a large-scale battery energy storage system supplied by Saft, TotalEnergies’ wholly owned affiliate.
The storage component is expected to help stabilise intermittent wind generation and improve overall grid resilience.
Mirny will consist of approximately 150 wind turbines and is structured as a joint venture, with TotalEnergies holding a 60 per cent stake.
Kazakh partners Samruk Energy and KazMunayGas each hold 20 per cent, reflecting a collaborative approach between international and domestic energy players.
Financing for the project has been secured through a consortium of international lenders, including the European Bank for Reconstruction and Development (EBRD), Proparco, Development Bank of Kazakhstan (DBK), DEG, Société Générale, QNB Group, China Construction Bank, and Standard Chartered.
The partners signed a Common Terms Agreement, establishing the financial framework needed to move the project into construction.
TotalEnergies emphasised the strategic importance of the development both for Kazakhstan and its broader regional renewable energy ambitions.
“We are delighted to launch one of Kazakhstan’s largest renewable energy initiatives to date, thereby contributing to the country’s target of increasing the share of renewables in electricity generation to 15 per cent by 2030,” said Olivier Jouny, SVP Renewables at TotalEnergies.
“We look forward to advancing construction of the Mirny project alongside our partners and in cooperation with the Kazakhstani authorities.
“This 1 GW onshore wind farm will also contribute to the 9 GW renewables portfolio that we are combining with Masdar through a 50/50 joint venture across nine Asian countries, including Kazakhstan.”
As Kazakhstan seeks to diversify its energy mix and reduce reliance on fossil fuels, projects like Mirny are expected to play a central role in modernising infrastructure and attracting foreign investment into the renewable sector.
