Today’s renewable energy news includes announcements on Amarenco, Grenergy, RWE, among others.
Amarenco Secures EUR 130m Equity Investment from Arjun Infrastructure Partners
Solar energy developer Amarenco has secured EUR 130 million (about USD 141 million) in equity investment from Arjun Infrastructure Partners to support the expansion of its renewable energy portfolio. The funding will help accelerate the development of solar and energy storage projects across Europe, particularly in Ireland, Spain, and Portugal. The investment strengthens Amarenco’s strategy to scale up clean energy generation while advancing innovative solutions such as agrivoltaics, which combine solar power with agricultural activities. By boosting capital for new projects, the partnership is expected to enhance renewable capacity, support energy transition goals, and deliver sustainable power for businesses and communities. The deal also highlights growing investor confidence in renewable infrastructure and long-term opportunities in the clean energy sector.
Grenergy Seeks Permits for 48.3-MW Battery Energy Storage Project in Spain
Spanish renewable energy company Grenergy has applied for permits to develop a 48.3-MW battery energy storage system (BESS) project in Spain as part of its strategy to strengthen grid flexibility and support renewable integration. The proposed project will help store excess electricity generated from renewable sources and release it during periods of high demand, improving energy reliability and efficiency. The development reflects growing investment in energy storage technologies across Europe, driven by the rapid expansion of solar and wind capacity. By advancing this project, Grenergy aims to enhance its clean energy portfolio while contributing to Spain’s energy transition goals. The battery system is expected to improve grid stability, optimize renewable power usage, and deliver long-term benefits for energy consumers.
RWE to Pilot Peak Energy’s Sodium-Ion Grid Battery in MISO Region
RWE has partnered with US-based Peak Energy to pilot a sodium-ion battery energy storage system in the Midcontinent Independent System Operator (MISO) region of the United States. The demonstration project will test Peak Energy’s sodium-ion technology for grid-scale storage, offering a potential alternative to lithium-ion batteries. Sodium-ion batteries use more abundant and lower-cost materials, which could reduce supply-chain risks and lower storage costs while maintaining strong performance for long-duration energy storage. The pilot will evaluate the technology’s efficiency, reliability, and commercial potential in real grid operations. If successful, the initiative could support wider adoption of innovative storage solutions, helping integrate more renewable energy into the grid while improving energy security and system flexibility.
