Overview
Kansas City Power and Light Company, commonly known as KCP&L, was an investor-owned electric utility whose roots lay in the first commercial electric-lighting ventures in Kansas City, Missouri. Its service territory ultimately covered the Kansas City metropolitan area and other communities in parts of Missouri and Kansas. The company supplied electricity to residential, commercial, industrial, and municipal customers, and over time developed a substantial generation, transmission, and distribution system. The enterprise traces its origins to November 1881, when Joseph S. Chick obtained rights to use the Thompson-Houston arc-lighting system in Jackson County, Missouri, and Wyandotte County, Kansas. The following month, a franchise for an electric works in Kansas City, Missouri, was granted to Lysander R. Moore and later assigned to Kawsmouth Electric Light Company. Kawsmouth constructed a generating plant in the West Bottoms and began serving its first 13 downtown customers on May 13, 1882. The business was reincorporated as Kansas City Electric Light Company in 1885. During the late nineteenth and early twentieth centuries, the Kansas City electricity market was fragmented and competitive. Companies were formed or separated to address different customer groups, including residential users, while electric utilities also became connected with the city’s street-railway system. J. Ogden Armour acquired control of important electricity and railway interests in 1900. Under Armour, the utility acquired competitors and built additional generation capacity, including a 1903 plant that supplied steam heat to downtown businesses. The close relationship with the trolley business contributed to financial weakness, and the company entered receivership in 1911. A 1917 reorganization separated the trolley operation and produced Kansas City Light & Power Company. President Joseph F. Porter emphasized modernization, efficiency, and expanded generating capacity. Construction of the Northeast Power station began that year. The company was reincorporated as Kansas City Power and Light Company in 1919, and after the 1922 acquisition of Carroll County Electric Company it adopted the ampersand form, Kansas City Power & Light Company. Armour sold his interest in 1923, and Continental Gas & Electric Corporation acquired control in 1924. That company later became associated with United Light and Power until the latter was dissolved in 1950. Under Porter’s 21-year leadership, KCP&L expanded its financial base and physical infrastructure. The company commissioned or developed major generating assets, including Hawthorn Station on the Missouri River, whose first unit was completed in 1951 and whose additional units were operating by 1956. KCP&L became independent in 1950 and acquired Eastern Kansas Utilities in 1952. It also participated in the consortium that developed Wolf Creek Nuclear Generating Station in Burlington, Kansas. In 2001, KCP&L became part of Great Plains Energy Incorporated. The utility moved its headquarters to One Kansas City Place in downtown Kansas City in 2009. A proposed 2016 combination with Westar Energy was rejected by Kansas regulators because of concerns about its effect on Kansas consumers. A revised transaction was announced in 2017 and received approval from the Missouri Public Service Commission and Kansas Corporation Commission in 2018. The resulting parent company was named Evergy, with KCP&L and Westar continuing initially as operating companies. On October 7, 2019, the operating companies adopted the Evergy name and branding in their communities, ending KCP&L’s independent public-facing identity.
History
Kansas City Power and Light Company developed from a series of nineteenth-century electric-lighting enterprises established in Kansas City, Missouri. In November 1881, Joseph S. Chick secured rights to use the Thompson-Houston arc-lighting system in Jackson County, Missouri, and Wyandotte County, Kansas. A municipal franchise was granted the next month to Lysander R. Moore and subsequently assigned to Kawsmouth Electric Light Company. Kawsmouth built a generating plant in Kansas City’s West Bottoms and began commercial illumination on May 13, 1882, initially serving 13 downtown customers. The company was reincorporated as Kansas City Electric Light Company in 1885. The emerging utility industry was marked by competition, consolidation, and changing relationships between electricity suppliers and street railways. A residential-focused business was spun off as Edison Electric Light & Power Company, while J. Ogden Armour acquired the principal electricity and railway interests in 1900. Armour’s organization purchased competitors, built a new generating plant in 1903, and supplied steam heat to downtown commercial properties. Its strong connection to the Metropolitan Street Railway Company later proved problematic. The company entered receivership in 1911 as the railway and utility interests struggled financially. In October 1917, the trolley business was separated and the reorganized electric company emerged as Kansas City Light & Power Company under President Joseph F. Porter. Porter made modernization a central priority, beginning construction of the Northeast Power station in 1917. The company was reincorporated as Kansas City Power and Light Company in June 1919. Following the acquisition of Carroll County Electric Company in July 1922, it used the Kansas City Power & Light name. Armour disposed of his interest in 1923, and Continental Gas & Electric Corporation acquired control in 1924. The utility was later associated with United Light and Power, which dissolved in 1950. Porter led the company for 21 years and oversaw a major expansion of its capital base and generating system. In 1931, the company commissioned the 32-story Kansas City Power and Light Building, a prominent downtown landmark associated with its corporate presence. KCP&L became independent in 1950 and expanded through the acquisition of Eastern Kansas Utilities in 1952. Its postwar generation program included Hawthorn Station on the Missouri River. Construction began in 1948, the first unit was completed in 1951, and two further units were operating by 1956. The company also joined other utilities in developing Wolf Creek Nuclear Generating Station near Burlington, Kansas. A corporate restructuring in 2001 made KCP&L part of Great Plains Energy Incorporated. The company relocated its offices to One Kansas City Place in downtown Kansas City in September 2009. Its proposed 2016 merger with Westar was rejected by Kansas regulators because the transaction was considered unfavorable to Kansas consumers. A revised plan announced in 2017 was approved by Missouri and Kansas regulators on May 24, 2018. The new parent company was called Evergy, while KCP&L and Westar initially remained operating companies. On October 7, 2019, the operating companies formally adopted Evergy branding, bringing the KCP&L brand’s independent public identity to an end.
