Today’s renewable energy news includes updates from Greenvolt Power, CIP, ENGIE, Renewable America, among others.
Greenvolt Power Connects 200-MW Battery Storage Facility to Poland’s Grid
Greenvolt Power, part of the Greenvolt Group, has successfully connected a 200-MW battery energy storage system (BESS) to Poland’s transmission grid in Nowa Wieś Ełcka, marking a major milestone for the country’s energy transition. The facility is designed to enhance grid stability, improve system flexibility, and support the growing integration of renewable energy sources across Poland. A key innovation of the project is its large-scale storage capability, developed in partnership with BYD Energy Storage. The battery system forms part of a broader 400-MW/1.6-GWh energy storage program being deployed in Poland, positioning it among the country’s most significant storage investments. The project delivers substantial benefits by storing excess renewable electricity and supplying power when demand increases, helping reduce grid congestion and renewable energy curtailment. It also strengthens energy security, improves reliability, and supports Poland’s decarbonization objectives. The connection of the Nowa Wieś Ełcka facility demonstrates the growing role of utility-scale battery storage in modernizing electricity networks and enabling a more resilient, sustainable, and renewable-powered energy system.
CIP Brings 220-MW/1,100-MWh Arena Battery Project Online in Chile
Copenhagen Infrastructure Partners (CIP) has achieved commercial operation of its Arena Battery Energy Storage System (BESS) in Chile’s Atacama Desert, bringing a 220-MW/1,100-MWh standalone battery project online. The facility, developed through CIP’s Growth Markets Fund II, is now supplying electricity to the Chilean grid and ranks among the country’s largest standalone battery storage projects. A key innovation of the project is its ability to store excess solar power generated during the day and discharge it during evening peak demand, helping address one of Chile’s biggest renewable energy challenges—solar curtailment and grid congestion in the north of the country. The battery system improves grid balancing, increases renewable energy utilization, and reduces dependence on carbon-intensive power generation. The project was completed on time and below budget and has also been approved under Article 6 of the Paris Agreement, enabling the generation of internationally recognized carbon credits. In addition, the facility supports Chile’s decarbonization strategy by enhancing energy security and enabling greater integration of large-scale solar resources into the national power system. The Arena BESS milestone further strengthens Chile’s position as one of Latin America’s leading energy storage markets and demonstrates the growing role of utility-scale batteries in accelerating the global clean energy transition.
ENGIE Acquires 250-MW/1,000-MWh Battery Storage Project in Poland
ENGIE, through its subsidiary Engie Zielona Energia, has agreed to acquire a 250-MW/1,000-MWh battery energy storage system (BESS) project from R.Power in Poland. The project, located in Tursko Wielkie in the Świętokrzyskie region, is at a ready-to-build stage, with construction expected to begin in early 2027. The battery facility will be one of the largest energy storage projects in Poland and will be strategically connected to the Połaniec power station, enabling more efficient management of electricity flows and reducing pressure on regional transmission infrastructure. Connection conditions have already been secured, while final environmental and administrative approvals are being completed. A key benefit of the project is its ability to store surplus renewable electricity and release it during periods of high demand, improving grid stability, flexibility, and reliability. The system will support the integration of growing solar and wind capacity while helping balance supply and demand in real time. The acquisition aligns with ENGIE’s long-term strategy to expand modern energy infrastructure in Poland and strengthen the country’s transition toward a cleaner, more resilient, and renewable-powered energy system.
