Large-scale Battery Deployment in Generation Platform

ongoing

The project will deploy a large-scale Battery Energy Storage System (BESS) adjacent to the Ribatejo Combined Cycle Gas Turbine (CCGT) at Carregado, Portugal. Designed to store and deliver over 3 000 TJ of renewable electricity over ten years, BESS is projected to save approximately 500 000 tons of CO2 emissions throughout its lifetime. By optimising energy storage capacity and reducing reliance on fossil fuels, the project will enhance the overall efficiency and environmental sustainability of the Portuguese power generation system. The project will store excess energy during low-demand periods and release it during peak-demand periods, thereby maximising the use of renewable energy sources and contributing to grid stability and reliability. With 150 MW of power and 360 MWh of energy storage capacity, this project will be one of the largest BESS systems deployed in Europe integrated with a CCGT for grid connectivity. It will be capable of supplying electricity to approximately 100,000 households. The project will ensure efficient operation and real-time energy management by leveraging advanced technology. The project leverages advanced Lithium Iron Phosphate (Li-ion LFP) technology, capable of two discharge cycles per day, and incorporates a state-of-the-art Energy Management System (EMS) for real-time monitoring and control. These innovations ensure efficient operation, optimal energy dispatch, and real-time energy management. As recognised by the European Green Deal, energy storage systems are essential to ensure the deployment of renewable energy sources (RES), manage intermittency and achieve climate neutrality by 2050. Moreover, in line with the REPowerEU Plan, RES energy storage solutions will pave the way for a cleaner, more flexible, and secure energy future for Europe by accelerating the shift away from conventional energy sources, such as coal and gas. In this context, this project is fully aligned with European policy objectives, directly contributing to emission reductions and supporting the transition towards a zero-emissions energy grid while reducing Europe’s dependency on fossil fuels. BigBATT will enhance Europe’s access to secure, sustainable, and net-zero technologies by providing a scalable, flexible, and innovative solution. The strategic location near the CCGT facility will enable seamless integration of the BESS into the existing infrastructure, efficiently connecting the batteries to the grid.This integration will foster the development of a competitive, structured supply chain, create jobs, and provide clean energy to the Lisbon region. Moreover, the project will drive cost reductions through manufacturing innovations - such as leveraging Lithium Iron Phosphate (LiFePO4) technology - and by collaborating with suppliers. It will also enhance efficiency and address resource constraints, contributing significantly to the transition towards a climate-neutral economy.
