Commitment and Compliance

All Basin Electric and subsidiary facilities are 100 percent environmentally compliant.

Through 2016, Basin Electric and subsidiaries had invested more than $1.6 billion in emissions control technology. More than $181 million was spend in 2015 alone to operate and maintain those controls.

Renewable energy

Recovered energy generation

Basin Electric is a recognized leader of wind energy development in the Upper Midwest. By year-end 2017, Basin Electric will have about 1,300 megawatts of renewable generation in its portfolio.

Crow Lake Wind, a $363-million wind project just east of Chamberlain, SD, was commissioned Feb. 27, 2011. Built by Basin Electric's subsidiary PrairieWinds SD 1, Inc., it is the largest wind project owned solely by a cooperative in the United States. Crow Lake Wind is also a first-of-its-kind community wind investment partnership, and its turbines are used to educate future wind technicians. The entire project consists of 108 General Electric 1.5-megawatt turbines – 100 owned and operated by PrairieWinds SD 1, Inc., one turbine sold to the Mitchell Technical Institute (MTI), Mitchell, SD, and the remaining seven are owned by a group of local community investors called the South Dakota Wind Partners.

PrairieWinds ND 1, Inc. was formed to develop a 115.5-MW wind project south of Minot, ND, called PrairieWinds 1. Power from PrairieWinds 1 flows to Basin Electric's customers through an interconnection with Western Area Power Administration's transmission system. These North Dakota wind projects provide benefits to rural communities including an increase to the state’s tax base resulting from the increase in revenues from property taxes, which are based on the value of the facility

Also, Basin Electric purchases the output of eight small power plants that generate electricity using waste heat produced by compressor stations along a natural gas pipeline.

Leland Olds Station

Leland Olds Station
  • In 2013, a $410-million project to add wet scrubbers to the Leland Olds Station near Stanton, ND, was placed into service. The scrubbers use limestone to remove sulfur dioxide emissions from the flue gas produced by the coal-based power plant’s two units.
  • More efficient turbines have been installed in Unit 2.
  • Some of the coal ash from the plant is recycled and sold for beneficial uses.
  • Variable speed drives have been installed on large motors. Their increased efficiency means less electricity will be used by plant systems.

Antelope Valley Station

Antelope Valley Station
  • At Antelope Valley Station near Beulah, ND, more than $319 million has been invested, to date, in capital pollution control asset investments.
  • Dry scrubbers use lime to capture and remove up to 90 percent of sulfur dioxide emissions from stack gases.
  • Baghouses capture and remove up to 99 percent of particulate matter. Each baghouse contains more than 8,000 35-foot tall bags.
  • The Antelope Valley Station is a zero-discharge facility, meaning water can only leave through evaporation.
  • Some of the coal ash is recycled and sold for beneficial uses.

Laramie River Station

Laramie River Station
  • More efficient turbines have been installed in the Laramie River Station’s three units near Wheatland, WY.
  • The plant is a zero-discharge facility, meaning water can only leave through evaporation.
  • Some of the coal ash is recycled and sold for beneficial uses.

Dry Fork Station

Dry Fork Station
  • The Dry Fork Station near Gillette, WY, is a zero-discharge facility, meaning water can only leave through evaporation.
  • The air cooled condenser reduces water use by reusing the water condensed from the steam cycle. 
  • Nitrogen oxides are reduced by low NOx burners, overfire air, and selective catalytic reduction.
  • A recirculating fluidized bed scrubber, using a dry lime hydration system followed by a fabric filter baghouse, controls air emissions. Those emissions include oxides of sulfur, hazardous air pollutants including mercury, hydrogen fluoride, hydrogen chloride, and particulate matter.
  • Mercury emissions are also controlled by injecting activated carbon and amended silicates.

Deer Creek Station

Deer Creek Station

The 300-megawatt Deer Creek Station in Brookings County, SD, employs efficient combined-cycle technology. The power plant features two turbines: a natural gas-fired turbine and a steam turbine that uses steam created by the waste heat from the gas turbine. This configuration is very efficient because it uses exhaust heat that would otherwise be released into the air.

Peaking plants

Culbertson Generation Station

Three Basin Electric generating units employ General Electric’s highly efficient LMS100® simple-cycle turbine technology.

Great Plains Synfuels Plant

Great Plains Synfuels Plant

Through subsidiary Dakota Gasification Company, the Great Plains Synfuels Plant near Beulah, ND, has been capturing carbon dioxide (CO2) since 2000.

As of Feb. 5, 2015, 30 million metric tons of CO2 has been successfully captured and delivered to customers.
