Rate Updates & Information

Keeping our commitments

When KCP&L and Westar merged in June 2018, the new company promised multiple benefits as a result of the merger. The company is continuing to deliver on its promises, and customers are noticing:

  • Customers received bill credits beginning in December thanks to initial merger savings and federal tax savings.
  • More merger credits are coming for some customers in February or March. Find the amounts in the chart below.
  • Rate case reviews completed in 2018 also reduced customer prices. 
  • Merger savings and efficiencies are on track with expected levels.
  • Since the merger was completed, in addition to maintaining the company's historic level of charitable giving, Evergy has made an additional $3.5 million in investments to support key community development projects in Topeka, Wichita and Pittsburg.
  • No involuntary layoffs as a result of the merger.
  • Employee presence and involvement in Topeka, Pittsburg, Wichita and other Kansas communities is evident on a daily basis. 
  • The company promised to complete a rate study, which was filed with the Kansas Corporation Commission (KCC) Jan. 14, 2019. 

Ultimately, we understand customers are tired of increases, and our rates are currently higher than some of our peers. We're happy to share that now that we've concluded rate increases necessary to recover investment costs, we're entering a period of rate stability and are ahead of the curve on environmental requirements, aligning our rates with the national average

We've committed to not change base rates until December of 2023, and beyond that, customers can expect fewer and smaller rate increases. 

Customers began receiving initial merger savings bill credits in December 2018 and can expect additional credits in the future. Below are approximate average amounts for residential credits:
