HiTHIUM has signed a strategic cooperation framework agreement with KNESS Group, an international renewable energy and energy solutions provider, to advance large-scale energy storage deployment in Eastern Europe, with a primary focus on the Ukraine market.
Under the agreement, the two companies plan to develop energy storage projects totaling 2 gigawatt-hours (GWh) over the next two years. The partnership will include multiple battery energy storage systems (BESS) with different durations, including 6.25 MWh and 5 MWh systems, with around 400 MWh scheduled for initial delivery in the first quarter of 2026.
The collaboration builds on previous project partnerships and aligns both companies on project planning, technology pathways, and delivery execution, laying the foundation for large-scale long-duration energy storage deployment in the region. The initiative comes amid accelerating renewable energy adoption in Eastern Europe, driving demand for grid stability, resilience, and backup power solutions.
HiTHIUM highlighted its ∞Power 6.25 MWh 2–4-hour BESS, emphasizing its high integration, safety, efficiency, and lifecycle economics, along with the company’s global manufacturing and delivery capabilities. The system is designed to support renewable integration and grid applications such as frequency regulation and power system stability.
Sam Wang, Sales Director at HiTHIUM, said long-duration energy storage is becoming critical infrastructure for regions with high renewable energy penetration, particularly in Ukraine. He added that combining HiTHIUM’s end-to-end capabilities with KNESS’s local market expertise will help deliver reliable and efficient energy storage solutions.
Andrii Khyzhniak, First Deputy General Director of KNESS Group, said the partnership reflects a shared commitment to accelerating energy storage deployment in Ukraine and strengthening the region’s power system security and sustainability.
The companies will further collaborate across project development, system integration, and delivery execution to expand the large-scale application of long-duration energy storage, supporting a safer, more efficient, and greener energy system in Eastern Europe.
