Missouri West Rate Case in 2024

Rates maintain a price advantage compared with neighboring states.

Evergy filed a request on Feb. 2, 2024 with the Missouri Public Service Commission to recover investments made to support generation capacity and improve the grid in order to provide reliable power. 

Evergy’s request includes investments related to power resources that will help ensure Evergy Missouri West has sufficient generation capacity for customers and to reduce Missouri West’s exposure to market price volatility for electricity purchased from the market.

Reliability improvements include:

  • Replacing aging infrastructure
  • Improving the ability to withstand more severe weather
  • Adding technologies that better outage performance and improve our predictive maintenance capabilities
  • Creating more power (or generation capacity) for customers, which also helps us...
    • Reduce exposure to big swings in pricing for electricity purchased from the market
    • This includes the cost to purchase Dogwood Energy Center to meet the growing needs of Missouri West customers

"We are investing strategically to ensure customers have reliable, affordable energy,” said Evergy President and Chief Executive Officer David Campbell. “Our focus continues to be on more efficiently running the business, which despite this period of record inflation has resulted in a reduced increase ask for our customers. While most area states have seen electricity costs increase about 11% over the past six years, Evergy’s prices have remained regionally competitive and even declined in some areas."

Where and what is changing?

The Evergy Missouri West service area serves more than 340,000 customers and includes St. Joseph, Liberty, Platte City, Harrisonville, and Warrensburg, among other cities. The majority of the Kansas City Metropolitan region is not in the Missouri West service area. Most Kansas City Metropolitan customers are in the Missouri Metro service area. Evergy is not asking for any changes to base rates in its Missouri Metro service area.

As part of the rate case filing, Evergy is requesting to increase base rates for Evergy Missouri West customers by about 13.42% (roughly $17 a month). The prices customers pay for electric service are calculated based on actual costs the company incurred and investments the company has made.

To justify any price increase, Evergy must show the costs were warranted and prudent. This request also includes a 0.57% increase to account for increased fuel costs.
Evergy has not requested structural changes to the time-based rate plans that were implemented in 2023.
