TotalEnergies Approves $1.2 Billion Mirny Wind and Storage Project to Advance Renewable Energy in Kazakhstan

(IN BRIEF) TotalEnergies has taken the Final Investment Decision for the Mirny wind and battery storage project in Kazakhstan, marking a major step in the country’s renewable energy development. The project combines 1 GW of wind capacity with a 600 MWh battery system, enabling the generation of approximately 100 TWh of electricity over 25 years—enough to supply around one million people. Backed by a $1.2 billion investment and supported by a consortium of international lenders, the initiative will enhance grid stability and contribute to Kazakhstan’s renewable energy targets. With TotalEnergies holding a majority stake alongside local partners, the project highlights the growing role of large-scale renewable and storage solutions in supporting energy transition and long-term sustainability.

(PRESS RELEASE) PARIS, 24-Apr-2026 — /EuropaWire/ — TotalEnergies has reached a major milestone in its renewable energy expansion by taking the Final Investment Decision and securing financing for the Mirny wind and battery energy storage project in Kazakhstan. The large-scale development, located in the southeast of the country, combines significant wind generation capacity with advanced storage technology to deliver reliable renewable power.

The Mirny project will integrate a 1 GW onshore wind farm, comprising approximately 150 turbines, with a 600 MWh battery energy storage system supplied by Saft, a wholly owned affiliate of TotalEnergies. The hybrid design is expected to strengthen grid stability while ensuring a consistent supply of renewable electricity.

Once fully operational, the project is projected to generate around 100 TWh of electricity over a 25-year period, sufficient to meet the needs of roughly one million people. The electricity will be sold to the Government of Kazakhstan under a long-term Power Purchase Agreement signed in 2023. Full commissioning of the facility is scheduled for 2029.

With an overall investment of approximately $1.2 billion, the project is financed largely through external funding, covering about 75% of total costs. TotalEnergies holds a 60% stake in the project, alongside partners Samruk Energy and KazMunayGas, each holding 20%.

To support the development, the project sponsors have secured a Common Terms Agreement with a consortium of international lenders. The financing group includes major institutions such as European Bank for Reconstruction and Development, Proparco, Development Bank of Kazakhstan, DEG, Société Générale, QNB Group, China Construction Bank, and Standard Chartered.

The Mirny project represents one of Kazakhstan’s most significant renewable energy developments to date and supports the country’s objective of increasing the share of renewables in its electricity mix to 15% by 2030. The inclusion of grid-scale battery storage marks a notable advancement in the country’s energy infrastructure, enhancing flexibility and reliability.

TotalEnergies has maintained a presence in Kazakhstan since 1993, combining its traditional hydrocarbon activities with growing investments in renewable energy. The company is also a stakeholder in the North Caspian Project and has developed solar assets in the country, while continuing to expand its renewable portfolio across Asia.

Globally, TotalEnergies is pursuing a strategy that blends renewable generation with flexible power solutions, including storage and gas-fired assets, to provide reliable and low-carbon electricity. As of early 2026, the company has more than 34 GW of installed renewable capacity and is targeting over 100 TWh of net electricity production by 2030.

About TotalEnergies in Kazakhstan

TotalEnergies has been present in Kazakhstan since 1993, deploying a multi-energy strategy that integrates hydrocarbon production with renewable development. The Company is a major shareholder (16.81%) in the North Caspian Project, ensuring the country’s economic stability, while simultaneously leading the renewable sector with 128 MW of operational solar assets. This commitment is further reinforced by the development of the 1 GW Mirny wind and BESS project, a technological benchmark featuring Kazakhstan’s first grid-scale battery system (600 MWh), designed to directly support the nation’s 2060 net zero ambition.
