Platte County approved a special use permit and rezone for a 150 MW, 4‑hour Battery Energy Storage System (BESS) proposed by Chugwater Energy Center/NextEra, subject to extensive fire, hazardous materials, and emergency response conditions. The permit requires compliance with IFC 1207 and NFPA 855, UL 9540/9540A testing documentation, a final Emergency Response Plan developed with local emergency responders, a Hazardous Materials Management and Spill Response Plan, groundwater reporting, and immediate contamination notification. These requirements mean Platte County emergency services will need BESS-specific pre‑incident planning, SOPs, training, and possibly specialized equipment once final plans are submitted and construction nears.NextEra has already agreed in the meeting to provide annual safety training for firefighters, but the county and local fire districts may still need third‑party support for plan development, tabletop and full‑scale exercises, documentation, and ongoing compliance updates as codes or technology change.

IFC 1207 sign‑off can be by the State Fire Marshal or a Platte County‑approved third‑party risk manager, indicating potential consulting procurement.
