Prairie Island Nuclear Generating Plant at Sunset

The twin concrete containment domes pictured here belong to the Prairie Island Nuclear Generating Plant, located along the Mississippi River just northwest of Red Wing, Minnesota. Operated by Xcel Energy, the facility houses two pressurized-water reactors that began commercial operation in the early 1970s. The domed structures serve as reinforced containment buildings, designed to house the reactor vessels and critical safety systems. Set against the river and surrounded by dense tree cover, the plant sits adjacent to the Prairie Island Indian Community, whose proximity has been central to public discussions about nuclear safety, spent-fuel storage, and long-term energy planning in Minnesota. The low evening light in this image highlights the muted textures of the domes and the teal-panel cladding of the turbine and support buildings, offering a clear view of one of the state’s most prominent pieces of energy infrastructure.
