en.Wedoany.com Reported - The retired Cottam coal-fired power plant in the UK is set for a major functional transformation. According to project plans, Holtec International of the United States and Électricité de France (EDF) will collaborate to build four SMR-300 small modular reactors at the site, converting this coal-fired plant, which once played a key role in the UK's energy system, into a low-carbon nuclear energy hub.
Each SMR-300 reactor is designed with a power generation capacity of approximately 300 megawatts, with the total installed capacity of the project expected to reach about 1.3 gigawatts upon completion. According to the plan, this power supply capacity can meet the electricity needs of a large number of households and will also provide new support for the UK's efforts to advance a low-carbon electricity structure.
The Cottam site was selected primarily due to its existing grid connection conditions, industrial infrastructure, and plant facilities being relatively well-developed. Compared to building nuclear facilities at a new location, repurposing a retired coal-fired power plant is expected to shorten construction timelines, reduce upfront investment, and alleviate the pressure of reconfiguring transmission and industrial land resources.
Small modular reactor technology is regarded as one of the key directions for nuclear energy development, characterized by modular manufacturing in factories followed by on-site installation. Compared to traditional large-scale nuclear power plants, SMRs offer advantages in construction flexibility, standardized production, and deployment speed, making them a potentially replicable solution for transitioning aging fossil fuel facilities.
The project still needs to complete licensing and planning approval procedures. If it proceeds smoothly, the Cottam project will become one of the world's largest cases of "coal-to-nuclear" conversion. The UK government's policy support for low-carbon energy development also gives this project significance not only for the country's energy transition but also as a potential reference model for other nations with retired coal-fired power assets.
