TotalEnergies SE (EU:TTE) has sanctioned and financed the Mirny onshore wind and battery storage development in southeast Kazakhstan, a $1.2 billion project combining a 1 GW wind farm—featuring 150 turbines—with a 600 MWh energy storage system provided by affiliate Saft.
The project is majority-owned by TotalEnergies, alongside partners Samruk Energy and KazMunayGas. Electricity generated will be sold under a 25-year agreement with the Kazakh government. Over its lifetime, Mirny is expected to produce enough renewable power to supply around one million people.
Supporting Grid Stability and Energy Transition
The integration of large-scale battery storage is designed to improve grid reliability and modernise Kazakhstan’s energy system. The project supports the country’s goal of increasing the share of renewables in electricity generation to 15% by 2030, as well as its long-term objective of achieving net-zero emissions by 2060.
Financing for the project is approximately 75% debt-based, backed by an international lending consortium that includes the European Bank for Reconstruction and Development and several major financial institutions. The development also strengthens TotalEnergies’ renewable energy footprint in Asia and aligns with its strategy of expanding stable, low-carbon electricity capacity in emerging markets.
