Sunterra RE Expands Bulgarian Solar Parks with 1.3GWh Battery Storage Capacity
Bulgarian renewable energy company Sunterra RE has completed the second phase of its battery energy storage expansion program, adding nearly 397MW/1.3GWh of battery energy storage systems (BESS) across three major solar parks in Galabovo, Kaloyanovo, and Karlovo. The facilities use advanced lithium iron phosphate (LFP) battery technology capable of delivering up to four hours of storage with approximately 90 percent efficiency, supporting long-term operation over a 25-year lifespan. The innovative solar-plus-storage projects are designed to store excess renewable electricity and deliver it during peak demand periods, improving grid flexibility, stability, and overall energy efficiency. Customer-focused benefits include enhanced energy security, reduced renewable energy curtailment, more reliable clean power supply, and improved electricity system resilience. The self-financed expansion strengthens Bulgaria’s rapidly growing battery storage market while supporting the country’s broader clean energy transition and decarbonisation goals. Sunterra RE said the projects form part of its long-term strategy to scale renewable energy storage infrastructure and optimize solar energy utilization across the region.
OX2 Approves Largest Solar Project and First Battery Storage Investment in Poland
Swedish renewable energy developer OX2 has taken final investment decisions (FID) for two major clean energy projects in Poland, including its largest solar farm to date and its first battery energy storage system (BESS) in the country. The projects include the 165MWp Lion solar farm in Lubuskie Voivodeship and a 50MW/120MWh battery storage facility in Osiek Jasielski, backed by long-term financing from NORD/LB and CaixaBank. The Lion solar project is expected to generate around 184GWh of clean electricity annually, enough to power approximately 51,000 households. The investment highlights innovation through the integration of large-scale solar generation with battery storage technology, improving grid flexibility and renewable energy reliability. Customer-focused benefits include enhanced energy security, more stable electricity supply, reduced carbon emissions, and improved integration of renewable power into Poland’s electricity system. The battery facility has secured a 17-year capacity market agreement, supporting long-term operational stability while helping balance growing renewable energy demand. The projects reinforce OX2’s expanding role in Poland’s clean energy transition and sustainable infrastructure development.
RWE Withdraws Ohio Solar and Battery Storage Project to Reassess Development Plans
RWE Clean Energy has withdrawn plans for the proposed 116.5MW Hillclimber Solar project with a co-located 40MW battery energy storage system (BESS) in Champaign County, Ohio. The company officially requested the Ohio Power Siting Board to dismiss its environmental compatibility application while reserving the option to resubmit the project in the future. Although no specific reason was disclosed, reports indicate RWE is evaluating the best path forward for the development. The project was designed to generate enough renewable electricity to power more than 18,000 homes annually, while the integrated battery storage system would improve grid flexibility and renewable energy utilization. The initiative highlighted innovation in solar-plus-storage infrastructure, combining clean power generation with energy storage to enhance reliability and support peak demand management. Customer-focused benefits included increased energy security, reduced carbon emissions, and improved access to sustainable electricity. Despite the withdrawal, RWE continues to expand its renewable energy and battery storage portfolio globally, reinforcing its long-term commitment to clean energy development and grid modernization.
