Evergy is an investor owned electric utility headquartered in Kansas City, Missouri, United States. The company was formed from a merger of Westar Energy of Topeka and Great Plains Energy of Kansas City, Missouri, parent company of Kansas City Power & Light. Evergy is the largest electric company in Kansas, serving 690,000 residential, commercial and industrial customers[1] in the eastern third of the state. Evergy generates more than 27,000,000 megawatt-hours of electricity per year at its 12 power plants in Kansas and Missouri. Evergy service territory covers 10,130 square miles (26,200 km2) in east and east-central Kansas. Evergy owns more than 6,300 miles (10,100 km) of transmission lines and about 28,100 miles of distribution lines.


Westar was the product of a 1992 merger between the two major electric companies in eastern Kansas, Kansas Gas and Electric (KG&E) of Wichita and Kansas Power and Light (KPL) of Topeka.

KG&E was founded in 1909 when the American Power and Light Company took over electric companies in Wichita, Pittsburg and Frontenac. Within a decade, it served over 48,000 people in 50 cities and towns. It also provided natural gas to several of the larger cities in its service territory.[2]

KPL was founded in 1924, and quickly expanded across northeastern Kansas. In 1983, it merged with The Gas Service Company, a natural gas utility serving customers in Kansas, Missouri, Nebraska and Oklahoma.[2]

In 1992, KPL merged with KG&E to become Western Resources, with KPL and KG&E as operating companies. The merger created one of the largest utilities in the Midwest, serving 560,000 electric customers and 1.06 million natural gas customers in three states. In 1996, Western Resources sold its natural gas business to ONEOK as Kansas Gas Service; this company is now part of ONE Gas. In return, Western Resources acquired a 45 percent stake in ONEOK; it sold this stake in 2003.[2]

In 2002, Western Resources officially changed its name to Westar Energy, and all of its subsidiaries began doing business under that name.[2]

In 2016, Great Plains Energy and Westar announced merger plans,[3] but this proposed merger was rejected by Kansas Corporation Commission utility regulators as unfavorable to Kansas consumers.[4] A new merger plan with Great Plains was announced in 2017.[5] As of May 24, 2018, this merger has been approved by both the Missouri Public Service Commission and the Kansas Corporation Commission, with the combined company to be named Evergy.[6] KCP&L and Westar became the two operating companies of Evergy.

Generation portfolio[edit]


In 1999, Western Resources restated its consolidated financial statements for 1999, 1998 and 1997 and for each of the periods of 2000, related to the Westinghouse Security Systems (WSS)acquisition.[7]

On January 14, 2003, Westar Energy Inc was charged for transactions involved power sales from one Cleco Corporation affiliate to Westar and then back to another or the same Cleco affiliate,[8] and paid $30,000,000 USD for settlement.

On Nov 1, 2002, Westar Energy announced to restate results for its first and second quarter, to account for additional impairment at its Protection One Inc.(POI) unit.[9]

On March 25, 2004, Westar Energy said to restate its 2003 annual financial results, after realizing that it might have understated its cash flow from operations for the year.[10]
