Marion County commissioners open working session on batteries and data centers, flag water, safety and economic trade-offs

Summary
The planning commission opened a working session on a 12-month moratorium for battery/energy storage systems and a 90-day moratorium for data centers; commissioners sought fire, environmental and utility input and set a one-hour follow-up work session in two weeks to draft recommended regulations.
The Marion County Planning Commission used a scheduled working session to put facts and concerns on the table about battery energy storage systems and data centers before recommending regulations to the county commission.
The chair opened the session by stating the moratorium durations: “The moratoriums for batteries for 12 months. The data center moratorium is for 90 days.” Commissioners said the goal is to produce a set of regulations and recommendations to the county commission by the end of the commission’s May meeting.
On battery and energy storage systems, commissioners debated numeric thresholds to separate residential backup systems from commercial-scale installations. The draft language referenced a prior resolution (2026-09) and thresholds described in it: “in excess of 10 megawatts” and “discharge in excess of 2 megawatts.” Members repeatedly emphasized protecting residential solar-plus-storage users from being unintentionally regulated out of ordinary backup systems.
Safety and environmental concerns predominated for energy storage: fire suppression methods, thermal runaway risks, containment and disposal of battery components, and training for local fire departments. One commissioner summarized the immediate concerns as “fire suppression, environmental.” Commission staff said they would contact county fire chiefs and state environmental authorities (KDHE) and seek any tier‑2 reporting materials from facilities that must file them.
The commission then heard an extended primer on data centers from a member with technology-industry experience. He outlined data center types (edge, colocation, hyperscaler, enterprise), discussed cooling approaches (air cooling, liquid/immersion and closed-loop systems) and warned that some cooling systems can use millions of gallons of water. He said a state statute and incentives (citing Senate Bill 98 in Kansas) can create sales-tax exemptions and that large projects sometimes enter long power-purchase agreements that commit infrastructure planning to multi‑year terms.
Members voiced mixed views about siting: several favored locating data centers in incorporated industrial parks rather than rural farmland to limit noise, traffic, security risks and impacts to agricultural land. Commissioners asked whether minimum setbacks (one discussed benchmark: 1,000 feet, with Barber County referenced for a 2,000-foot example) should be required, how to prevent abandonment or decommissioned shells, and what local benefits (such as equipment donations to schools) might be negotiated even when long tax abatements are offered.
The commission agreed to a limited one‑hour work session in two weeks focused on data centers and directed staff to circulate a focused agenda and relevant regulatory examples. Staff confirmed special meetings require public notice (about 10 days) and that a virtual link will be included on the agenda.
Next steps recorded in the session included staff follow-up with KDHE and county fire chiefs on containment and suppression, research on closed-loop versus open-loop water systems, and compiling examples of county regulations elsewhere for the commission to review.
