Voltalia has announced the start of construction work on the first phase of the Artemisya hybrid complex located in the Bukhara region of Uzbekistan. This development combines 100 megawatts of wind power capacity with an energy storage system of 100 megawatts / 200 megawatt-hours. It is the first infrastructure of its kind in Central Asia, integrating multiple renewable sources and a large-scale storage facility.
A project built around long-term agreements
The first phase of this project follows the signing, on December 5, 2025, of investment agreements in the presence of the President of the Republic of Uzbekistan. In March 2025, Voltalia signed a Power Purchase Agreement (PPA) with the Uzbek government during a ceremony held at the Élysée Palace. The agreement provides for a 25-year supply duration for the solar and wind capacities, and 15 years for the storage.
Eventually, the Artemisya complex will include 126 megawatts of solar, 300 megawatts of wind, and 100 megawatts / 200 megawatt-hours of battery storage. The current phase concerns only the 100 megawatt wind section and the storage infrastructure.
National targets and commissioning timeline
The Uzbek government aims to reach eight gigawatts of renewable energy capacity by 2026 and twelve gigawatts by 2030. The Artemisya complex aligns with this strategy, aiming to enhance the flexibility of the national grid while securing power supply.
Full commissioning of the complex is scheduled for 2027, following the completion of the various construction phases. This project adds to the Sarimay power plants, also developed by Voltalia, whose initial units entered service last November.
Deployment of a regional-scale hybrid model
The uniqueness of the Artemisya project lies in its integration of solar, wind, and storage technologies within a single infrastructure. This hybrid approach is designed to ensure greater grid stability and optimise the management of production variability. According to Voltalia, this configuration could be replicated in other countries seeking to diversify their energy sources while securing their grids.
Robert Klein, Chief Executive Officer of Voltalia, stated: “The launch of this project demonstrates our commitment to supporting Uzbekistan in its energy transition. With the Sarimay complexes and Artemisya, we are significantly strengthening the country’s low-carbon power capacity.”
