Power outages at Tampa Bay c-stores cluster in summer afternoons (thunderstorms), hurricane events, and the occasional grid trip. Cold-side equipment behaves differently during an outage than during a refrigeration failure — the box stays cold but loses control of cycle, then warms predictably as door cycles continue. The runbook is structured.
Confirm the outage is a power loss, not equipment failure. Check the breaker panel — sometimes a single condenser unit trips and looks like a partial outage. Call Duke Energy or TECO outage line to confirm grid status and get an ETA. Do not open any cold equipment unless absolutely necessary; closed boxes hold cold for hours, opened boxes don't.
For the beer cave: close the door, post a sign, lock if possible. The box holds 38°F for 4–6 hours closed. For the foodservice walk-in: same — closed door, sign, no entry. For glass-door merchandisers: leave doors closed. For frozen drink machines: power down at the disconnect (when power restores, surge protection matters). For ice machines: same.
If the outage is short (under 2 hours), TCS food in the foodservice walk-in is fine. Beer in the beer cave is fine. Frozen drink machines hold slush product 30–60 minutes; if outage extends past 60 minutes, dispense is past saleable but not yet wasted. Document the start time of the outage in the daily log.
If grid is restored within 4 hours, equipment recovers without intervention in most cases. Verify each cold equipment cycles back to setpoint within 90 minutes of power restore. Frozen drink machines need a fresh cleaning cycle before returning to dispense (CIP cycle is required by manufacturer spec after any power interruption longer than 60 minutes).
TCS food cold-holding compliance matters now. After 4 hours above 41°F, TCS product must be discarded under FDA Food Code §3-501.16 (verify with thermometer at the product, not the equipment). Document the discard with photographs and weight estimates for insurance.
For hurricane events with 24+ hour outages, generator runs become essential. Most c-stores don't have refrigeration on emergency power; the dispensing system has priority. Pre-position dry ice or rented refrigerated trailers for high-value product. See the hurricane prep article (cross-vertical to hotels) for the broader runbook.
Each condenser cycles back on (verify within 5 minutes). Each evaporator runs (verify air movement). Controllers show in-spec. Frozen drink machines are restarted only after a fresh CIP cycle. Ice machines restart and produce within 90 minutes; if not, escalate. Document the full recovery timeline.
Most c-store property insurance covers refrigeration product loss with documentation of the outage event.
4–6 hours typical, 6–10 hours if door stays closed and box was at setpoint when outage started.
When product temperature exceeds 41°F for more than 4 hours total, per FDA Food Code §3-501.16 / §3-501.19. Verify at the product, not the equipment.
For most c-stores, dispensing has priority on emergency power. Cold-side runs only if generator capacity allows. Pre-position dry ice or rented refrigerated trailers for extended outages.
