EE 438 - North Central States Power Technology Tour

The summer senior technical elective course (1 cr) is numbered EE 438. The CPSS has sponsored this biannual North Central States Power Technology Tour for over 30 years. The most recent tour was offered in August of 2017. This is a very popular course, having met its maximum capacity every year it has been offered (maximum enrollment is 10 students).

EE 438 Course Objectives

Introduce students to the variety of technologies associated with the electrical power industry. Tour various sites and learn about the generation, transmission, and distribution of power. Tour sites are associated with the power community, from large power producers (such as federally operated dams, IOU's, and electric power cooperatives) to end-users of electrical power (such as mining operations, paper mills, and foundries).

Oahe Dam (Hydroelectric Power)

The Oahe Dam is a large dam along the Missouri River, just north of Pierre, SD. It creates Lake Oahe, the fourth largest artificial reservoir in the United States, which stretches 231 miles (372 km) up the course of the Missouri to Bismarck, ND. The dam's power plant provides electricity for much of the north-central United States. The project provides flood control, electric power, irrigation, and navigation benefits, estimated by the Corps of Engineers at $150,000,000 per year.

Coteau Freedom Mine (Coal Mine)

The North American Coal Corporation's Freedom Mine in Beulah, ND - established in 1983 - delivers more than 16 million tons of coal per year, making it the largest lignite mine in the United States in deliveries. The operation utilizes two Bucyrus-Erie® 2570 draglines for overburden removal and reclaims about 600 acres of land annually.

Cass County Electric Cooperative Control Center

Cass County Electric Cooperative is a not-for-profit, member owned electric distribution system, serving more than 35,000 consumers in a 10-county area in southeastern North Dakota.


Hibtac Mining Company

Cliffs directly or indirectly owns and operates interests in five U.S. Iron Ore mines located in Michigan and Minnesota. These U.S. Iron Ore mines produce from deposits located within the Biwabik and Negaunee Iron Formation, classified as Lake Superior type iron-formations formed under similar sedimentary conditions in shallow marine basins approximately two billion years ago. Magnetite and hematite are the predominant iron oxide ore minerals present, with lesser amounts of goethite and limonite. Quartz is the predominant waste mineral present, with lesser amounts of other chiefly iron bearing silicate and carbonate minerals.

Forbes 500 kV Transmission Substation

Xcel Energy operates an SVC in its 500kV power transmission network between Winnipeg and Minnesota.  This device is located at Forbes substation in Minnesota.  The purpose is to increase the power interchange capability on existing transmission lines.  This solution was chosen instead of building a new line as it was found superior with respect to increased advantage utilization as well as reduced environmental impact.  With the SVC in operation, the power transmission capability was increased in about 200MW.

Arrowhead DC Terminal

Square Butte is the designation of a high voltage direct current transmission line in the USA between the Milton R. Young Power Plant near Center, ND, and the Arrowhead converter station near Hermantown, MN. It was built by Minnkota Power Cooperative and Minnesota Power and went in service in 1977. Recently, an agreement was executed between the two companies whereby Minnkota gets the rights to all the power currently transmitted over the line (and will build a new line to carry said power later) while Minnesota Power takes full ownership of the line to transmit power from new sources in the Center area.

Midwest Energy

The Superior Midwest Energy Terminal (SMET) was commissioned in 1976 to provide for the low sulfur western coal needs of the DTE Electric Company power plants located in southeastern Michigan. This state-of-the-art transshipment facility incorporates the economic advantages of both unit train receipt and "superlaker" Great Lakes vessel shipment. The terminal facility has sufficient capacity and design flexibility to accommodate the coal transshipment needs of additional electric utilities and industrial firms throughout the Great Lakes region. We are a full service energy terminal, and, as such, can provide directly for coal deliveries from the mine to the end user.
