Project; the project only included Chicago Park and Dutch Flat. Smaller plants were created in the 1980s to take advantage of existing water releases including the Rollins powerhouse. The Rollins power plant generates a capacity of about 12.15 megawatts alone. With all of the NID power plants put together the plants generate 82.2 megawatts or on average about 375 million kilowatt hours of energy in a year.
