Kansas is powered by many sources but primary sources of energy are oil, coal, natural gas and nuclear. Kansas has substantial renewable energy resources, especially wind power. Competitive and Uninterrupted Electric Power Kansas’ competitive electricity rates are partially due to our proximity to the low-sulfur coalfields of Wyoming, resulting in low transportation costs. The majority of electric power generated in Kansas comes from such coal. A modern generation and distribution network also keeps Kansas’ electric rates competitive. Three investor-owned companies produce more than one-half of the electric power for the state; one in Kansas (Westar) and two in Missouri (Kansas City Power & Light and Empire Electric). The remainder is supplied by three in-state, member-owned Generation and Transmission (G&T) cooperatives and 65 municipal generating systems. Sixty of the 65 municipal generating systems interconnect with investor-owned systems. A support network of 30 distribution cooperatives and 119 municipalities enhances the electrical system. This system connects with a multi-state power transmission grid, including most of the electric systems east of the Rocky Mountains. Kansas has not experienced a major power shortage in many years. Should one occur, the reserve power capacity of the three major investor-owned companies alone far exceeds the national generating capacity. Electric Energy Companies list.
