The Sedgwick County Board of County Commissioners voted unanimously March 11 to impose a one‑year interim development control (an interim moratorium) on certain battery energy storage system (BES) zoning applications while staff studies safety, land‑use and regulatory options.
Deputy County Counselor Kirk Sponsel told the board the measure targets applications where a BES is the primary use or where it is an ancillary system with anticipated energy storage capacity of 600 kilowatts or more — a threshold chosen from American Planning Association guidance to separate residential installations from larger commercial or standalone systems. The pause is set for one year, until May 12, 2027, or sooner if the board adopts permanent regulations.
Sponsel said the county has observed growing interest in a range of battery systems and wants time to evaluate hazards, fire‑safety controls, environmental impacts and planning standards before approving new projects. "Given the broad range of these types of systems, there could be significant impacts on safety, natural resources and human services," he said.
Commissioners asked about interactions with ongoing data‑center pauses and with solar applications that might include storage. County counsel and staff clarified that completed applications filed before a moratorium's effective publication are typically processed under the rules in place when they were submitted. If an application combines solar and storage and the storage component meets the moratorium threshold, the moratorium would prevent acceptance of the new application after the moratorium takes effect.
The board adopted the interim development control by unanimous roll‑call vote (5–0). Sponsors said staff will use the year to draft comprehensive regulations and report back to the board, including recommended safety standards and zoning criteria.
What happens next: County planning staff will research best practices, engage emergency‑services and planning partners, and return with draft regulatory language for the commission to consider before the moratorium expires.
