Use of refined coal grows

The U.S. power sector is increasingly shifting to refined coal and now makes up nearly one-fifth of coal-based generation. Use increased from 17 percent in 2016 to 19 percent through the end of the third quarter of 2017, according to the U.S. Energy Information Administration. Refined coal has been processed to remove certain pollutants from […]

Electric system weathers arctic temps

The new year brought with it frigid temperatures contributing to very high winter demand for electricity across the Midwest, including on the Great River Energy system. “If you provide electricity in Minnesota, you need to be prepared for this type of weather – and the market conditions that often follow,” said Great River Energy Vice […]

Energy market benefits members

The electricity that toasts your breakfast and cools your milk could be produced at a wind turbine in Minnesota, a power plant in North Dakota or a hydroelectric dam in Manitoba. And, over the course of a day, you might receive electricity from all three. Great River Energy is a member of the Midcontinent Independent […]

A new way forward in environmental standards

Bees, butterflies, eagles and moose. These are the majestic, native animals of Minnesota, and just like Great River Energy’s member cooperatives, they live in our local communities.

Coal ash recycling rates hit record high

Coal ash recycling across the United States has reached a record high according to the American Coal Ash Association (ACAA). Out of the 107.4 million tons of coal combustion products (CCPs) created, 60.2 million tons were recycled – 56 percent. For the last several years, Great River Energy’s Coal Creek Station power plant has recycled […]

Grant awarded to determine greenhouse feasibility

The North Dakota Ag Products Utilization Commission (APUC) recently awarded Great River Energy and North American Coal (NAC) a $75,000 grant to assist with determining the feasibility of co-locating a commercial greenhouse at Coal Creek Energy Park. “The availability of excess heat and carbon dioxide at a common location presents a unique opportunity for a […]

Today’s electricity comes from many sources

Electric cooperatives have supplied reliable electricity to Minnesotans for nearly 80 years. The way electricity is generated has change a lot over that time, with new fuels and technologies contributing to greater efficiency and lower emissions. The Midwest’s most efficient coal and nuclear power plants remain critical to reliable energy, but several new types of […]

Talent meets technology

Operators use advanced systems, skills to manage electric grid In a dark, windowless room at a Great River Energy location, a mosaic of 50-inch monitors displays information about the electric grid that supplies power to consumers around Minnesota and Wisconsin. Operators monitor the grid 24 hours a day, 365 days a year, working twelve hour […]
