Keep refrigeration safe in an outage

Businesses in foothills and wind-exposed areas faced this directly in Xcel’s December 2025 and March 2026 wildfire shutoffs, which lasted a day or more in places. Rural co-op territory adds weather outages on long lines. A cooler that stays closed buys a few hours; a multi-day shutoff doesn’t.

Refrigeration compressors cycle on and off, and each start draws a surge. We size inverter capacity for simultaneous starts, then size energy for the hours or days you want to cover. Critical loads — coolers, freezers, controls, a point-of-sale system, a few lights — go on a backed-up subpanel.

Backing up only critical loads, rather than the whole building, is usually what makes this affordable.

A standby generator runs as long as there’s fuel and is often cheaper up front for large loads. A battery switches over instantly without the brief gap many generator transfer switches create, runs silently, and does useful work every day by shaving demand peaks. Some businesses pair a battery with a smaller generator for extended events.

Commercial storage remains eligible for the federal §48E credit through construction starting in 2033, subject to rules on foreign-entity sourcing, and can be depreciated. The daily demand-charge savings are part of the return. We model all three with an explicit “ask your CPA” on the tax pieces.
