Voltalia Begins Construction of 330MW Hybrid Cluster in Uzbekistan
Event summary
- Voltalia has commenced construction on the Artemisya hybrid cluster in Uzbekistan, encompassing 100MW/200MWh of storage and 100MW of wind capacity.
- The project is underpinned by a 25-year electricity sales contract for solar and wind, and a 15-year contract for storage, signed in March 2025.
- The total Artemisya cluster capacity will be 126MW of solar, 300MW of wind, and 100MW/200MWh of battery storage.
- Construction is scheduled for completion and commissioning in 2027, following investment agreements signed on December 5, 2025.
The big picture
Voltalia's Artemisya project highlights the growing trend of hybrid renewable energy solutions in emerging markets, particularly those seeking to modernize their power grids and meet ambitious decarbonization goals. Uzbekistan's commitment to 12GW of renewable capacity by 2030 positions it as a key market for international renewable energy players. This 330MW project represents a significant contribution to Uzbekistan’s energy mix and demonstrates the increasing importance of energy storage in enabling greater renewable energy penetration.
What we're watching
- Execution Risk
- The successful integration of solar, wind, and storage technologies within a hybrid cluster presents technical challenges, and delays could impact the project's profitability and Voltalia's reputation.
- Regulatory Landscape
- Uzbekistan’s commitment to renewable energy targets and the stability of the 25-year PPA will be crucial for Voltalia’s long-term investment returns, and any policy shifts could create uncertainty.
- Grid Integration
- The extent to which Artemisya’s flexibility enhances Uzbekistan’s power system reliability and enables greater renewable energy penetration will determine the project’s strategic value and potential for future expansion.
