The plant's single Combustion Engineering pressurized water reactor generated 484 megawatts of electricity. This was the smallest rated capacity among all operating commercial power reactors in North America, and as a single-unit plant, this also qualified it as the smallest rated capacity nuclear power plant. OPPD's two Nebraska City coal-fired plants at 682 (opened 2009) and 649 (opened 1979) MW are both significantly larger.
