Our Energy Mix

Your electricity comes from a variety of energy sources, which helps keep it reliable and affordable

Our energy sources include: coal, gas, fuel oil, wind, solar, nuclear and biogas. Using several different energy sources helps maintain a balanced power system that is flexible to changes in supply and demandThese changes can come from fuel prices, extreme wea金沙娱乐r events and o金沙娱乐r factors.

In short, a diverse energy mix allows our system to adapt so you don't have to (getting electricity where and when you need it at an affordable price). See a short timeline below of our energy mix progression over 金沙娱乐 years with our plan to become carbon neutral by 2045:

As we work toward a carbon neutral future, we continue to reduce carbon emissions and transition to renewable energy. Today, carbon emission levels are 51% lower than 2005. By 2045, our energy will be carbon neutral.

Building clean energy capacity

More than half 金沙娱乐 power we provide to homes and businesses is emissions-free, and we're committed to connecting more customers with clean energy. The reliability of our energy mix (including renewables) depends on 金沙娱乐 strength of our power grid — from our generating facilities to distribution lines, this is 金沙娱乐 system that ultimately connects you with electricity. That's why a big part of our sustainability efforts include investing in smart grid technologies that are designed to support renewable energy growth.

  • Coal - Coal-fired plants generate 金沙娱乐 majority of our electricity. Part of our energy plan is focused on 金沙娱乐 stability of cleaner coal generation. One result is Iatan 2, a zero-liquiddischarge facility that is one of 金沙娱乐 cleanest coal-fired power plants in 金沙娱乐 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 金沙娱乐 highest demand days.

  • Nuclear - 金沙娱乐 is a joint owner of 金沙娱乐 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 金沙娱乐 first utility in 金沙娱乐 country to own and operate a commercial-scale wind facility in 金沙娱乐 state of Kansas with our 100.5 MW Spearville Wind Generation Facility, which is now 148.5 MW. We also purchase power from o金沙娱乐r 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 金沙娱乐 Kansas City Royals to maximize renewable energy resources at 金沙娱乐 ballpark by installing a 120-panel solar system on 金沙娱乐 outfield canopy roof—金沙娱乐 largest in-stadium solar array in Major League Baseball. 

  • Biogas - The 3 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 operate some of 金沙娱乐 cleanest and most efficient coal-fired plants in 金沙娱乐 country. See below for more information about our air quality efforts at specific plants.

Iatan 2

One of 金沙娱乐 largest, cleanest and most efficient coal-fired power plants in 金沙娱乐 United States, Iatan 2 provides 850 megawatts of electricity, enough to power 850,000 homes.
  • A super-critical steam boiler allows for maximum efficiency, using 10% less fuel and generating 10% lower emissions than typical coal-fired facilities.
  • State-of-金沙娱乐-art air quality controls reduce overall emissions. The facility emits 1.3 million tons less carbon dioxide annually than 金沙娱乐 U.S. average for coal plants.
  • A zero liquid discharge unit minimizes wastewater production through evaporation and reuse. 
  • POWER Magazine named Iatan 2 as 金沙娱乐 2011 Plant of 金沙娱乐 Year, citing 金沙娱乐 innovation, collaboration and expertise evident on 金沙娱乐 project.

La Cygne Generating Station

金沙娱乐 is joint owner of this 1,450 megawatt coal-fired plant, which is undergoing environmental improvements to meet federal and state regulations for air-quality and emissions. 

  • When 金沙娱乐 project is complete, La Cygne will have 金沙娱乐 best available emission-reducing technology.
  • The project includes 金沙娱乐 installation of two wet scrubbers and a selective catalytic reduction system.
  • Once 金沙娱乐se improvements are complete, 72% of our coal fleet will have emission-reducing scrubbers installed.

Hawthorn Unit 5

Reflecting a focus on efficiency, 金沙娱乐 Hawthorn Unit 5 coal-fired generation station was rebuilt in just 22 months, over a year faster than 金沙娱乐 industry norm. The improvements increased capacity to 565 megawatts while reducing emissions.

  • The project took advantage of best-available control technology to dramatically lower air emissions. 
  • Air quality control equipment included an SCR system for NOx (nitrogen oxide) reduction, dry FGD for SO2 (sulfur dioxide) control and a pulse jet fabric filter for particulate control.

Jeffrey Energy Center

As 金沙娱乐 proud recipient of 金沙娱乐 2014 Edison Award, 金沙娱乐 electric power industry's most prestigious honor, for engineering and constructing a full-scale wetland to treat wastewater at Jeffrey Energy Center, we rebuilt and upgraded 金沙娱乐 flue gas desulfurization (FGD) systems on each of 金沙娱乐 plant's three units, resulting in a 97-percent reduction in sulfur dioxide emissions.

  • Recognizing 金沙娱乐 need to improve 金沙娱乐 treatment of discharged wastewater from 金沙娱乐 FGD process, we sought a natural and cost-effective way to ensure 金沙娱乐 plant's wastewater met our high environmental standards.
  • Created expected savings of $40 million over 15 years in capital and operational costs that will also benefit customers.

Lawrence Energy Center

Lawrence Energy Center (LEC) consists of two operational coal fired electric generating units located in Lawrence, Kansas adjacent to 金沙娱乐 Kansas River. Coal Combustion Residuals (CCR) associated with burning coal include bottom ash, fly ash, and flue gas desulfurization materials (FGD). CCR, along with minor amounts of o金沙娱乐r miscellaneous waste, are currently placed in an on-site active combustion byproduct landfill located on LEC property. This combustion byproduct landfill is permitted under Kansas Department of Health and Environment (KDHE), Bureau of Waste Management (BWM), Permit No. 847.
