Voltalia constructing hybrid renewables-plus-storage ‘cluster’ in Uzbekistan

Voltalia has officially started construction of a large-scale hybrid renewable energy and battery storage cluster in Uzbekistan, marking a significant milestone in the country’s clean energy transition. Known as the Artemisya project, the development integrates wind power, solar PV, and battery energy storage within a single, coordinated energy complex designed to enhance grid stability and security of supply.

The Artemisya hybrid cluster is being developed in the Bukhara region, western Uzbekistan. This area offers strong wind resources and high solar irradiation, making it well-suited for diversified renewable generation. Its proximity to key transmission infrastructure also enables efficient grid integration and system support at a national level.


Project Configuration and Technical Scope

Artemisya stands out as one of the most advanced hybrid energy projects currently under development in Central Asia, combining multiple technologies to deliver dispatchable, low-carbon power.

Battery Energy Storage System (BESS)

  • Installed capacity: 100 MW / 200 MWh

  • Designed to provide grid balancing, peak shaving, and frequency support

  • Enables higher penetration of variable renewable energy by mitigating intermittency

Wind Power – Phase 1

  • Installed capacity: 100 MW

  • Further wind capacity planned in subsequent phases

  • Expected to benefit from favorable regional wind conditions and strong capacity factors

Solar PV (Planned Phase)

  • Total planned capacity: 126 MW

  • Will complement wind generation by strengthening daytime production and smoothing the overall generation profile when combined with storage


Project Timeline

  • Construction start: End of 2025

  • First phase commissioning: Targeted for 2027

  • The project is structured for phased delivery, allowing progressive integration of generation and storage assets.


Commercial Structure and Power Offtake

Voltalia has secured long-term revenue visibility through a Power Purchase Agreement (PPA) signed with Uzbekistan’s state electricity offtaker, Uzenergosotish.

  • Renewable generation PPA duration: 25 years

  • Storage services contract: 15 years

This contractual framework underpins the bankability of the project and reflects Uzbekistan’s growing experience with utility-scale renewable procurement.


Contribution to Uzbekistan’s Energy Transition

The Artemisya project aligns closely with Uzbekistan’s national energy strategy, which targets:

  • Approximately 8 GW of renewable capacity by 2026, and

  • Around 12 GW by 2030.

By integrating wind, solar, and battery storage, Artemisya supports not only capacity growth but also system flexibility, a critical requirement as the share of variable renewables increases.


Regional and Corporate Context

Artemisya builds on Voltalia’s expanding footprint in Uzbekistan, following earlier solar developments such as the Sarimay PV plant and additional co-located wind and storage projects in the pipeline. Together, these investments highlight Voltalia’s long-term commitment to the Uzbek market and its broader Central Asian strategy.


Conclusion

The Artemisya hybrid renewables-plus-storage cluster represents a next-generation energy model for Uzbekistan and the wider Central Asian region. By coupling large-scale wind and solar generation with utility-grade battery storage, the project delivers cleaner power while strengthening grid reliability. As hybrid projects become increasingly central to energy transition strategies worldwide, Artemisya is positioned to serve as a benchmark for future developments in emerging renewable markets.
