    hydropower plant• The primary producer of hydroelectric power in North Dakota is the Garrison Dam.

    • The Garrison Dam produces, on average, 2.2 billion kilowatt-hours of electricity annually. In 2011, due to additional water release from flooding of the Missouri River, the dam’s generators produced 2.6 billion kilowatt-hours.

    • Garrison Dam has five hydroelectric power turbines with a total rated capacity of 583 megawatts.

    • Electric power generated from the Garrison Dam is marketed by the Western Area Power Administration.

    • Completed in 1954, Garrison Dam is the fifth largest earthen dam in the United States. The dam is 2.5 miles long. It cost about $300 million to build the dam.

  2. Wave Energy study update

    Leave a Comment

    Forbes did a great article on ocean-wave energy generating technology. What I found the most interesting was the new government-sponsored study results on the energy potential. The study found that oceans surrounding the US could potentially supply some 1,170 terawatt-hours annually. The author states that more energy “crashes annually onto the West Coast, for instance, than California uses in a year.” According to the article, 5 megawatts are currently being produced worldwide by wave energy.
