Today’s renewable energy news includes announcements from Cero, Enso, Alpiq, SEIA, and others.
Cero and Enso Reach Financial Close on 78 MWp Solar-Plus-Storage Project in UK
Cero Generation and Enso Energy have achieved financial close on a 78 MWp solar photovoltaic project combined with battery energy storage in the UK, advancing hybrid renewable deployment in the country. The co-located solar and storage facility is designed to enhance grid flexibility, optimize power output, and support the UK’s clean energy transition. The project integrates utility-scale solar generation with battery storage to capture price arbitrage opportunities and provide balancing services. Financial close enables construction to move forward, reflecting investor confidence in solar-plus-storage assets backed by strong revenue models. Once operational, the site will deliver low-carbon electricity while improving system stability, reinforcing the UK’s strategy to scale flexible renewable energy infrastructure.
Alpiq Acquires 535 MW Pumped Hydro Storage Project in Spain
Alpiq has acquired a 535 MW pumped hydro energy storage project in Spain, strengthening its flexible generation and storage portfolio in the Iberian market. The large-scale pumped storage facility will play a crucial role in balancing intermittent renewable energy, particularly solar and wind, by storing excess electricity and dispatching it during peak demand periods. The acquisition aligns with Alpiq’s strategy to expand its renewable and storage assets across Europe, supporting grid stability and energy security. Spain’s rapidly growing renewable capacity increases the need for long-duration storage solutions such as pumped hydro. The 535 MW project underscores rising investment in energy storage infrastructure as utilities and developers accelerate efforts to integrate higher shares of clean power into national grids.
US Battery Storage Installations Reach 58 GWh in 2025, SEIA Reports
Battery storage installations in the United States reached 58 GWh in 2025, marking a record year for the rapidly expanding energy storage sector, according to the Solar Energy Industries Association (SEIA). The milestone reflects strong growth across utility-scale, commercial, and residential storage segments as grid operators seek greater flexibility and reliability. The surge in deployments highlights increasing integration of battery energy storage systems (BESS) alongside solar and wind projects to manage peak demand, balance intermittent generation, and enhance grid resilience. Policy incentives, falling technology costs, and rising renewable penetration continue to drive investment momentum. The 58 GWh figure underscores the accelerating role of battery storage in supporting the US clean energy transition and modernizing power infrastructure nationwide.
