Today’s renewable energy news includes announcements from OX2, Electrica, Trina Storage, among others.
OX2 to Add 50 MW of Battery Storage to Swedish Wind Farm
OX2 has announced plans to co-locate a 50-MW battery energy storage system (BESS) with its Fageråsen wind farm in Malung-Sälen, Sweden, further enhancing the flexibility and value of the renewable energy project. The battery installation will complement the 189-MW onshore wind farm, which is currently under construction and is expected to generate approximately 550 GWh of renewable electricity annually. The co-located battery system will enable excess wind-generated electricity to be stored and discharged during periods of high demand, improving grid stability, balancing services, and renewable energy utilization. By integrating storage with wind generation, OX2 aims to increase the project’s power contribution, reduce curtailment, and create a more resilient energy supply. This approach reflects the growing trend of combining renewable generation with battery storage to maximize operational efficiency and revenue stability. The project supports Sweden’s clean energy transition by strengthening the flexibility of the electricity network and facilitating greater integration of renewable power. Once operational, the combined wind and storage facility will contribute to energy security, lower carbon emissions, and help meet increasing electricity demand in southern Sweden. The development also aligns with OX2’s strategy of expanding its renewable energy portfolio through hybrid projects that combine generation and storage technologies.
Electrica Secures Grid Approvals for 700-MWh Battery Storage Portfolio in Romania
Romanian utility Electrica has obtained technical grid connection approvals for 17 battery energy storage system (BESS) projects with a combined storage capacity of approximately 700 MWh, marking a major milestone in the company’s energy transition strategy. The approvals confirm the technical conditions required for grid connection and allow the projects to advance into the design, permitting, and construction phases. The battery portfolio forms part of Electrica’s 2030 Strategy, which targets the development of 1 GW of power generation capacity and at least 900 MWh of energy storage. The company aims to commission all 17 battery projects by the end of 2027, strengthening Romania’s energy infrastructure and supporting the integration of renewable energy sources. A key benefit of the storage programme is its ability to improve grid flexibility, reliability, and energy security while enabling higher levels of solar and wind power integration. Battery storage will help balance electricity supply and demand, optimize network operations, and reduce renewable energy curtailment. The latest approvals build on Electrica’s growing storage portfolio, which includes the 22-MWh Vulturu BESS and the 69.93-MWh Fântânele project, reinforcing the company’s role in Romania’s transition to a cleaner, more resilient, and low-carbon energy system.
Trina Storage Enters Global Top 5 BESS Integrators, Earns Wood Mackenzie Grade A Rating
Trina Storage has been ranked among the world’s Top 5 battery energy storage system (BESS) integrators and awarded Grade A BESS Integrator status in Wood Mackenzie’s Global Battery Energy Storage System Integrator Comprehensive Ranking 2026. The recognition reflects the company’s strengths in manufacturing, vertical integration, R&D, supply chain stability, technology maturity, financial performance, safety and ESG. A key factor behind the ranking is Trina Storage’s Cell-to-AC integration capability, combining battery technology, AC-side conversion and system integration to improve project execution and lifecycle value. The company also highlighted its advanced AC validation platform, international certifications and integrated delivery model demonstrated through its Gamma project, featuring the Elementa + Electra solution. The latest ranking reinforces Trina Storage’s growing position in the rapidly expanding global utility-scale energy storage market.
