Certain Energy, a UK long-duration energy storage company formerly known as RFC Power, has raised £10 million in a Series A funding. It was led by the British Business Bank, with participation from Centrica, Ceres Power and Temasek Trust’s C3H. The company will use the funding to commercialize its manganese-based flow battery technology, scale toward volume production. Plans also include development of a grid-connected MWh-scale system in India. It will also expand its UK research facility and build a supply chain for future projects. Certain Energy launched in 2017 as a spin-off from Imperial College.
Indian EPC group Larsen & Toubro (L&T) has secured a major order to develop three battery energy storage system (BESS) projects in the Middle East. The projects will have a combined storage capacity of 6 GWh, with each system designed for four hours of storage and discharge. L&T will also handle grid interconnections, including pooling substations and underground cables. The BESS projects will use liquid-cooling technology and are intended to support grid stability and renewable energy integration. L&T has not disclosed the client or project locations.
Eos Energy Enterprises, a US-based manufacturer of zinc-based long-duration energy storage systems, plans to consolidate its battery manufacturing operations at its Thorn Hill facility in Warrendale, Pennsylvania. The move will shift battery manufacturing from its Turtle Creek site, while Cube assembly, testing and shipping will continue there. Eos expects the consolidation to reduce conversion costs by 10% to 15%, with savings beginning in 2027. Once both production lines are operating, Thorn Hill is expected to have about 4 GWh of annual nameplate capacity. The transition is expected to start in Q4 2026 and finish in early 2027.
European Energy, a Danish renewable energy developer and operator, brought 167 MW/545 MWh of battery energy storage systems (BESS) into operation within first eight months of 2026. This capacity is located across Denmark, Lithuania and Latvia. The initial rollout has focused on co-located batteries at existing renewable energy projects, with further BESS deployments planned in Europe and Australia. The company said the batteries can improve project economics, create additional revenue opportunities and support grid balancing. It plans to use the data and experience to next generation of projects.
India’s ACME Solar Holdings has secured INR 1,571 crore in long-term project funding from India Infrastructure Finance Company Ltd. (IIFCL) for a 300 MW assured peak power project in Rajasthan. The project has a total capex of INR 2,123 crore and will integrate 1,350 MWh of battery energy storage with solar generation. The company also commissioned 15 MW/240.752 MWh of BESS in Rajasthan on August 27, 2026 taking the commissioned capacity of its subsidiary ACME Suryodaya to 300 MW/1,354.224 MWh. Separately, ACME Solar’s subsidiary has signed a PPA with Northeast Frontier Railway for a 130 MW round-the-clock (RTC) renewable energy project at INR 4.35/kWh for 25 years, with supply scheduled to begin in February 2029.
Rongjie Energy, a Chinese battery cell manufacturer, has signed a 4 GWh framework agreement with India’s Lineage Power. Under the contract, Rongjie will supply LFP battery cells to Lineage in 2027. The agreement covers 314 Ah and 588 Ah cells for utility-scale and commercial and industrial (C&I) energy storage applications. It follows an earlier 3 GWh cooperation agreement between the two companies signed in June 2026.
Renewable energy company Greenvolt Group has secured a €218 million financing package from UniCredit for its Ełk and Turośń battery energy storage projects in Poland. The package includes €153 million in bridge facilities and €65 million in guarantees. The two projects have a combined capacity of 400 MW/1.6 GWh, with each rated at 200 MW/800 MWh. Turośń Kościelna was inaugurated in July this year while Ełk is expected to begin commercial operations in Q4 2026. Greenvolt says these are two of Poland’s largest BESS projects.
