Duke Energy brings new grid battery on line at former Allen coal plant

Core Viewpoint - Duke Energy is advancing its energy transition by implementing battery energy storage systems (BESS) to enhance reliability and support economic growth in the Carolinas [4][6]. Group 1: Battery Energy Storage Systems - Duke Energy has launched a 50-megawatt BESS at the former Allen coal plant, completed under budget at approximately $100 million, and began serving customers in November [2][9]. - A second, larger BESS of 167 megawatts is set to begin construction in May, utilizing the site of a demolished emissions control system [2][7]. - Both BESS projects qualify for federal investment tax credits, which will cover 40% of the costs, including an additional 10% for reinvestment in an energy community [3][5]. Group 2: Future Plans and Investments - Duke Energy's 2025 Carolinas Resource Plan anticipates adding 6,550 megawatts of battery storage by 2035, sufficient to power over 5 million homes during peak energy use [5]. - The company plans to construct a 115-megawatt BESS at the Riverbend site, with construction expected to start in late 2026 and operational by late 2027 [7]. - A proposed third BESS at Allen is planned to be operational by the end of 2028, along with a regional operations and training facility for batteries and renewables [8]. Group 3: Economic and Community Impact - The initiatives aim to repurpose existing energy infrastructure while leveraging federal funding to reduce costs for customers [4][6]. - Duke Energy's long-term strategy includes maintaining a diverse energy mix, incorporating solar, storage, nuclear, and natural gas to meet rising electricity demand [6][12]. - The company emphasizes its commitment to the local community, with former employees from the Allen plant now working on the new battery projects [8].
