A report in the Wall Street Journal shows South Dakota has joined a small list of states with hydropower as the main source of electric generation.
South Dakota Public Utilities Commissioner Chris Nelson says that is true, to a point…………

Nelson says much of the hydropower generated at dams on the Missouri River is exported……….

The Wall Street report said that in 2001 the state used 968 million megawatts of electricity produced by coal. In 2014 that has dropped to 777 million megawatts. At the same time, hydropower has increased from 730 million megawatts to 893 million megawatts.
Nelson says our power sources continue to change………

South Dakota was the only state outside the Pacific northwest that had hydro as the largest source of power production.
