The project, built by Envision Energy in conjunction with Kazakhstan Utility Systems LLP, has a total investment of $40 million and is expected to be commissioned in the third quarter of 2026, with a designed annual capacity of 2GW of wind turbines (250 units) and 1GWh of energy storage systems (about 100 sets).
