Council hears conceptual pitch for battery storage at airport site; members ask for clearer public benefit

Lee's Summit — A conceptual presentation by SMT Energy on Jan. 5 introduced a proposed battery energy storage system (BESS) on roughly 5 acres near the municipal airport and an adjacent Evergy substation. The developer requested a Chapter 100 pilot abatement on personal property (10 years, 75%) to reduce up‑front equipment costs; staff counsel summarized the request and municipal fiscal impact in conservative tables.

SMT described the project as a grid‑stability asset that stores low‑value electricity and resurfaces it during peak demand, helping to smooth prices and provide short‑term capacity. Project capital was described as just under $10 million, with approximately $3 million in construction spend and the largest share of cost in batteries. Developer representatives said the request amounted to roughly a 5% assistance to the capital stack and that the abatement would reduce a financing barrier for projects of this type in the Midwest.

Council questioned who benefits most from the project — Evergy as an off‑taker or end‑use consumers through price stability — and whether the modest city tax impact justified public assistance. Multiple council members said Evergy may capture the direct operational benefit and that the city should seek quantifiable consumer or local economic benefits before granting tax incentives. Councilors also flagged opportunity cost for the 4–5 acre site, downstream infrastructure limits (no sewer), and potential fire and evacuation risks associated with lithium‑ion battery incidents. Fire Chief Jim Eden explained that lithium‑ion BESS fires can involve thermal runaway, long‑duration incidents, toxic smoke, and potential evacuation zones; best practices and certification were discussed but not seen as eliminating all risk.

Staff noted the project is conceptual and that the next steps would include a system impact/interconnection study with Evergy, a permitting path and more detailed fiscal analyses including pilot schedule mechanics. Council feedback was mixed: some members cited modest positive fiscal figures for the city and low ongoing service demand, while others urged caution and recommended seeking state or regional support for incentives given the cross‑jurisdictional nature of electrical grids.

Why it matters: BESS projects are emerging infrastructure that can support grid reliability and decarbonization goals, but they raise novel local policy questions about safety, fiscal incentives for primarily private‑sector energy arbitrage, and municipal opportunity cost. The council asked SMT and staff for more detailed, measurable evidence of consumer benefit, a clearer interconnection analysis, and safety/evacuation planning before moving an incentive forward.

Next steps: SMT will continue interconnection analysis with Evergy and refine the financial/pilot schedule. Council asked for additional technical, fiscal and safety details before considering a Chapter 100 incentive.
