Our Energy Mix

We supplement with energy generated from other sources to create a diverse energy mix.

Nearly half of the power we provide to homes and businesses are now emissions-free while continually exploring ways to broaden our sustainable strategy and comply with renewable energy mandates. Our diverse energy mix results in affordable, reliable electricity generation.

Some of our other energy sources include: gas, fuel oil, wind, solar, nuclear, biogas and hydro. Utilizing these other energy sources results in a balanced portfolio that's responsive to fuel prices, environmental issues, regulatory initiatives and other factors.

Our generating facilities provide approximately 6,400 megawatts (MW) of capacity for our customers. They allow us to follow environmental regulations while reliably meeting customer needs at an affordable price. Find more details on our current energy mix within our Evergy Inc. investor filings
  • Coal - Coal-fired plants generate the majority of our electricity. Part of our energy plan is focused on the stability of cleaner coal generation. One result is Iatan 2, a zero-liquiddischarge facility that is one of the cleanest coal-fired power plants in the United States. The La Cygne Generating Station has also undergone significant environmental improvements to meet federal and state regulations for air quality and emissions. Roughly 75% of our coal fleet has emission-reducing scrubbers.

  • Natural Gas - Our natural gas peaker plants help us meet energy needs on the highest demand days.

  • Nuclear - Evergy is a joint owner of the Wolf Creek Generating Station, a nuclear power plant in Burlington, Kan. Utility companies often rely on nuclear power as a cost-effective way to provide reliable energy for base load generation. 

  • Wind - We were the first utility in the country to own and operate a commercial-scale wind facility in the state of Kansas with our 100.5 MW Spearville Wind Generation Facility, which is now 148.5 MW. We also purchase power from other wind energy providers. 

  • Solar - Solar panels atop Paseo Academy have a capacity of 100 kilowatts while teaching local children about our energy future. The effort is part of our SmartGrid Demonstration Project. We’ve also partnered with the Kansas City Royals to maximize renewable energy resources at the ballpark by installing a 120-panel solar system on the outfield canopy roof—the largest in-stadium solar array in Major League Baseball. 

  • Biogas - The three million tons of decomposing waste in St. Joseph, Mo.’s landfill continually produce methane, which our Landfill Gas-to-Energy Plant converts into enough electricity to power up to 1,000 homes annually. We also purchase electricity from the Hampton Feedlot in Triplett, Mo., where up to 2,500 cattle produce manure that is converted into energy. 

  • Hydro - We've signed a 10-year agreement to buy renewable energy from Central Nebraska Public Power and Irrigation District's three hydroelectric plants. This is the first addition of hydro power to our energy mix.
