Voltalia has commenced construction of the Artemisya hybrid energy cluster in Uzbekistan, covering battery storage and the first phase of wind capacity. The initial phase includes a 100 MW/200 MWh battery energy storage system (BESS) project and a 100 MW wind project. The project is located in the Bukhara region in the country. The entire Artemisya cluster is planned to comprise 126 MW of solar capacity, 300 MW of wind capacity, and 100 MW/200 MWh of battery storage.
The company entered into a power purchase agreement with the Government of Uzbekistan for the Artemisya project in March 2025. The contractual framework includes a 25-year electricity sale agreement for solar and wind generation and a 15-year contract for battery storage. Once construction activities are completed, commissioning is scheduled for 2027. Construction of the first phase was launched after the signing of investment agreements in December 2025. Uzbekistan has a renewable energy target of reaching 8,000 MW by 2026 and 12,000 MW by 2030.
In November 2025, Masdar signed a battery storage service agreement with JSC Uzenergosotish to develop a standalone battery energy storage system project in Uzbekistan. The 300 MW/600 MWh Zarafshan BESS project in Navoiy will be connected to the Murunau substation and forms the first phase of a broader national battery storage programme.
REGlobal’s Views: Uzbekistan’s renewable energy market is growing rapidly and has attracted many other global clean energy majors like ACWA Power and Masdar apart from Voltalia. The country is witnessing an expansion of not just solar and wind power portfolios but also energy storage to ensure grid stability. For instance, Voltalia itself is implementing another very large 500-megawatts/1-gigawatt-hours storage project called Turan Storage in the country.
