Slide 4 What is coal-based electricity? Slide 5 Part of power plant that turns water into steam. Slide 6 What is a boiler? Slide 7 It sprays the exhaust gases from the boiler with limestone or lime- water to remove sulfur dioxide to comply with environmental regulations. Slide 8 What is a scrubber? Slide 9 The result of steam passing through a turbine generator. Slide 10 What is electricity? Slide 11 The largest coal-fired electrical generating power plant in North Dakota. Slide 12 What is Coal Creek Station? Slide 13 30 million tons mined each year in North Dakota. Slide 14 What is lignite? Slide 15 This material is stored in stockpiles for reclamation. Slide 16 What is subsoil and/or topsoil? Slide 17 The primary machine used to remove overburden. Slide 18 What is a dragline? Slide 19 Process to restore land to pre- mined conditions. Slide 20 What is reclamation? Slide 21 Agency that regulates surface coal mining in North Dakota. Slide 22 What is the Public Service Commission? Slide 23 Association whose primary objective is to maintain a viable lignite coal industry and enhance development of the regions lignite coal resources. Slide 24 What is the Lignite Energy Council? Slide 25 Generated from lignite and is used by over 2 million consumers and businesses in the Upper Midwest. Slide 26 What is electricity? Slide 27 Source of 82% of electricity produced in North Dakota. Slide 28 Source of 95% of electricity produced in North Dakota. What is lignite or lignite-fired power plants? Slide 29 Fraction of lignite comprised of moisture. Slide 30 What is 1/3? Slide 31 Lignite supply (in years) that is currently accessible in Western North Dakota. Slide 32 What is 800?
