TotalEnergies has taken the Final Investment Decision and secured financing for the Mirny onshore wind and battery energy storage (BESS) project in southeast Kazakhstan, marking one of the largest renewable energy initiatives in the country. The 1 GW wind farm, with 150 turbines and a 600 MWh battery system supplied by TotalEnergies’ affiliate Saft, is expected to generate around 100 TWh of electricity over 25 years.
The project’s output will be sold under a 25‑year power purchase agreement (PPA) signed in 2023 with the Kazakh government, with total investment of $1.2 billion and about 75% externally financed. TotalEnergies holds a 60% stake, alongside partners Samruk Energy and KazMunayGas (20% each). The inclusion of grid‑scale storage will enhance grid stability and serves as a technological benchmark for the country’s power system.
TotalEnergies and its partners have signed a Common Terms Agreement (CTA) with an international lending consortium including the EBRD, Proparco, DBK, DEG, Société Générale, QNB Group, China Construction Bank and Standard Chartered, establishing the financing framework for the project. The company said the Mirny site will form part of a broader 9 GW renewables portfolio being developed with Masdar across nine Asian countries, including Kazakhstan.
The Mirny project underscores TotalEnergies’ long‑standing presence in Kazakhstan since 1993, combining hydrocarbon operations with a growing renewables footprint that already includes 128 MW of operational solar capacity and adds what will be the nation’s first large‑scale battery system ahead of its 2060 net‑zero target.
