Evergy is planning to add new renewable and dispatchable generation, according to the utility’s triennial Integrated Resource Plan filed with the Missouri Public Service Commission this week.

Over the next 20 years, Evergy projects it would need to add 5,100 MW of renewable energy from wind and solar and 5,200 MW of firm, dispatchable generation – including 2,500 MW of natural gas generation across 2029-2032.

Evergy notes its service area, representing Kansas and Missouri, is experiencing record-setting demand driven by economic development. The utility’s 2024 plan includes 1,900 MW of additional generation over what was expected in its 2023 update filing. The IRP also calls for the retirement of more than 4,500 MW of coal-fired generation and the continued growth of demand-side programs over that period. 

In the short-term, Evergy plans to add 143 MW of new natural gas generation in 2024 and 600 MW of solar energy in 2027 and 450 MW in 2028.   

Right now, nearly half of the energy that serves Evergy customers comes from carbon-free sources, including the Wolf Creek nuclear plant. The company said it has reduced carbon emissions by more than 50 percent since 2005. The utility’s goal is to reduce carbon emissions by 70 percent by 2030 compared to 2005 levels, and to achieve net-zero carbon emissions by 2045.
