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
No confirmed utility-scale solar projects on public record as of Mar 2026.
Denied/Withdrawn Projects
No confirmed KCC or county-level CUP denial on record for Sumner County as of Mar 2026. Kansas KCC approves utility-scale cost recovery; county BOCC handles CUP applications. No statewide solar siting preemption — county retains full authority to deny CUPs. Key KS denials statewide: Harvey County permanent ban; Pottawatomie moratorium (Resolution 2023-60, Nov 27 2023, ~Nov 2026); Shawnee County 1-yr moratorium 2025.
