Voltalia Launches Construction of Artemisya Hybrid Energy Cluster in Uzbekistan

Tashkent, Uzbekistan (UzDaily.com) — International company Voltalia announced the start of construction of the strategic Artemisya hybrid energy cluster in Uzbekistan, which will include a 100 MW / 200 MWh energy storage system and a 100 MW wind installation. The project marks an important step in developing the country’s energy storage infrastructure.

In March 2025, Voltalia signed a power purchase agreement (PPA) with the government of Uzbekistan at a ceremony held at the Élysée Palace. This contract became a key milestone for implementing Artemisya — the first hybrid cluster in Central Asia combining solar and wind generation with energy storage. The partnership is based on a 25-year contract for the sale of electricity from solar and wind installations and a 15-year contract for the use of storage facilities: 126 MW of solar generation, 300 MW of wind generation, and 100 MW / 200 MWh of battery storage.

Construction of the first phase of the project — including the 100 MW / 200 MWh storage system and the first 100 MW wind unit — officially began on December 5, 2025, in the presence of the President of Uzbekistan following the signing of investment agreements. The facility is scheduled to be commissioned in 2027.

The Artemisya hybrid cluster, located in Bukhara Region, will enhance the flexibility and reliability of Uzbekistan’s power system, support the national goal of reaching eight gigawatts of renewable capacity by 2026 and twelve gigawatts by 2030, and significantly reduce CO₂ emissions through the use of clean energy.

Voltalia CEO Robert Klein emphasized: “The launch of this project demonstrates our commitment to supporting Uzbekistan’s transition to clean energy. With the Sarimay cluster commissioned last year and Artemisya, we are making a significant contribution to strengthening the country’s low-carbon generation. Hybrid solutions with storage play a key role in ensuring grid stability and integrating renewable energy.”
