en.Wedoany.com Reported - Portuguese energy group EDP (Energias de Portugal) recently announced that its Punta de Talca BESS project in the city of Ovalle, Chile, has been commissioned. This is EDP's first battery energy storage complex in South America, with an installed capacity of 240 megawatt-hours and an average annual storage capacity of 60 gigawatt-hours. The project aims to increase the share of renewable energy in Chile's power mix and is expected to supply electricity to over 30,000 local households.
The project, with an investment of approximately $44 million, integrates a battery energy storage system with the Punta de Talca wind farm, which has been operational since 2024. The wind farm has an installed capacity of 83 megawatts. The configuration of this hybrid plant is designed to reduce wind power curtailment: storing excess electricity during periods of low demand and releasing it during peak demand hours. This not only optimizes the plant's revenue but also helps enhance the stability of Chile's power system and reduce reliance on fossil fuels.
João Brito Martins, CEO of EDP South America, stated that this project is a strategic milestone for EDP in the region, reinforcing the role of energy storage in building a more resilient and sustainable power system. He believes that the operation of the Chilean complex demonstrates how combining renewable energy with batteries can improve operational efficiency and reduce energy waste. Brito Martins also noted that such solutions will play an increasingly important role in the evolution of regional power systems and sees significant development potential in the Brazilian market in the coming years.
Since entering the South American market approximately three decades ago, EDP has established Brazil as its main market and a strategic platform for regional growth. The company operates in nearly all Brazilian states, covering the entire value chain including power generation, transmission, distribution, and energy commercialization.
In the same week, EDP also announced the completion of the Flatland Energy Storage project. Located in Arizona, USA, the project was developed in partnership between EDP Renewables North America (EDPR NA) and the utility company Salt River Project (SRP). The Flatland project is EDP Group's largest battery energy storage system (BESS) to date, with a capacity of 200 megawatts/800 megawatt-hours, capable of meeting the electricity needs of approximately 44,500 households during peak demand periods, supporting the state's continued growth in energy demand.
Miguel Stilwell d'Andrade, CEO of EDP Group, stated that power systems are becoming increasingly complex, with energy demand continuing to grow, making investment in more resilient systems ever more important. As EDP Group's largest energy storage project, Flatland plays a key role in strengthening grid stability and resilience. Bobby Olsen, Vice President and Chief Power System Executive at SRP, also noted that the project is part of SRP's diversified strategy to provide reliable, affordable, and sustainable electricity to its customers, and the company will continue to invest in battery storage as part of its expanding portfolio. EDP stated that it is committed to expanding energy storage as one of the core pillars of the energy transition, with operational and under-construction storage capacity exceeding 460 megawatts across the United States, Europe, South America, and the Asia-Pacific region.
