Grid, Utilities & State Context

Grid Operator
SPP (Southwest Power Pool)
Utilities
Evergy Kansas Central
State Permitting Process
No statewide siting preemption for utility-scale solar. County-level conditional use permits (CUPs) required. Significant local opposition emerging: Sedgwick Co. moratorium 2023-2024; Butler Co. banned solar in Flint Hills 2023; Harvey Co. banned large utility solar. Some counties have quarter-mile or half-mile setback buffers (Kearney Co.; Gage Co.).
State Incentives
No Kansas RPS (Renewable Portfolio Standard). Kansas Corporation Commission (KCC) approves utility-scale cost recovery. Kansas Sky Energy Center (Douglas County, 159 MW) approved by KCC July 7 2025 ($228M, Evergy). SPP (Southwest Power Pool) grid. No property tax exemption for solar. Evergy (formerly Westar + KCP&L) serves eastern KS; Sunflower Electric serves western KS.

Development Activity

Active/Completed Projects
Prairie Sky Solar (KEPCO) | 1 MW | Butler County | Kansas Electric Power Cooperative (KEPCO) + Butler Electric Cooperative | operational Pony Meadows Solar | Butler County | Butler Electric Cooperative | operational 1 MW each — two solar farms on Butler Electric system (Butler EC news). Butler County limits solar farm size and BANS solar in Flint Hills ecoregion (August 2023 regulations).
Denied/Withdrawn Projects
Butler County Commission approved new restrictive solar regulations August 2023: banned solar in Flint Hills ecoregion; limited farm size; expanded urban growth area restrictions. Chicago-based OneEnergy Renewables project stalled by regulations (KMUW Nov 2023). Dawson family's solar lease contract canceled after new regulations passed.
