Today’s renewable energy news includes updates from Frontier Power, Helios Nordic Energy, battery energy storage market in Bulgaria, among others.
Frontier Power Acquires 480MWh Battery Storage Portfolio in Texas
Frontier Power has agreed to acquire a 480MWh battery energy storage portfolio in Texas from Broad Reach Power, strengthening its position in the rapidly expanding US energy storage market. The portfolio includes four utility-scale battery energy storage system (BESS) projects located within the ERCOT power market, one of the fastest-growing renewable energy regions in the United States. The investment highlights growing demand for advanced battery storage infrastructure designed to improve grid reliability, renewable energy integration, and electricity market flexibility. The projects will support energy shifting, peak demand management, and grid stabilisation while enabling greater adoption of wind and solar generation across Texas. Frontier Power emphasized innovation in energy management technologies and scalable battery storage solutions to meet evolving clean energy requirements. The customer-focused acquisition supports long-term energy resilience, operational efficiency, and sustainable electricity delivery while reinforcing Texas’ transition toward a more flexible, low-carbon, and renewable-powered energy system.
Helios Nordic Energy Sells 125MW Finnish Battery Storage Project
Helios Nordic Energy has sold a 125MW/250MWh battery energy storage system (BESS) project in Finland to an undisclosed buyer, further strengthening the Nordic region’s rapidly expanding energy storage market. The transaction increases the company’s total divested BESS capacity in Finland to more than 550MW/1,100MWh over the past six months, highlighting strong investor confidence in large-scale storage infrastructure. The investment supports Finland’s renewable energy transition by improving grid stability, enhancing electricity flexibility, and enabling greater integration of wind and solar power into the national energy system. Helios Nordic emphasized that advanced battery storage technologies are becoming increasingly important for balancing intermittent renewable generation and supporting long-term energy reliability. The customer-focused strategy reflects growing demand for scalable and sustainable energy storage solutions across Europe. Helios Nordic continues expanding its Nordic renewable development pipeline, focusing on solar parks, battery storage, and data centre infrastructure to support decarbonisation and resilient clean energy networks.
Bulgaria Emerges as Europe’s Fast-Growing Energy Storage Hub
Bulgaria is rapidly becoming one of Europe’s leading battery energy storage markets, with installed battery capacity surpassing 3.3GW in 2026. The country’s strong growth has been driven by large-scale investments, streamlined permitting procedures, and government-backed funding under the National Recovery and Resilience Plan (NRRP). The expansion highlights major innovation in battery energy storage systems (BESS), enabling renewable energy producers to store excess solar power during the day and deliver electricity during peak evening demand. Bulgaria added nearly 2.5GWh of new battery capacity in 2025 alone, making it one of the EU’s fastest-growing storage markets. Recent projects, including large-scale standalone batteries and hybrid solar-plus-storage facilities, are improving grid flexibility, energy reliability, and renewable integration across the region. The customer-focused investments are strengthening energy security, supporting decarbonisation goals, lowering dependence on fossil fuels, and positioning Bulgaria as a strategic clean energy and storage hub in Southeast Europe.
