Before winter, walk through the house as if utility power had just disappeared and would not return until the day after tomorrow.

Use 48 hours as a stress test, not a prediction.

Massachusetts emergency guidance notes that outages can last from a short interruption to days or longer depending on the damage. We use 48 hours as a practical planning exercise: long enough to expose dependencies, short enough to walk through without imagining an extreme scenario.

Walk through what stops working.

  1. Heat: Does the heating system itself need electricity for controls, pumps, blowers or ignition? What is the safe fallback?
  2. Water: Municipal water may continue, but a private well normally needs power. If you have a sump, ejector or treatment system, include that too.
  3. Food and refrigeration: What needs to stay cold, and what does your actual backup system power?
  4. Communications: Routers, ONTs, cordless phones, chargers and cellular coverage all have their own power dependencies.
  5. Access and security: Garage doors, gates, cameras, alarms, smart locks and intercoms may behave differently when utility power disappears.
  6. Medical and household essentials: Identify anything that cannot simply wait two days.

A generator is a tool, not the whole plan.

Backup generation only helps if the transfer equipment, fuel, loads and operating procedure are understood. Massachusetts fire-safety guidance also emphasizes working carbon-monoxide alarms and safe outdoor generator operation. Those details matter more than the nameplate wattage.

Try the question this way: If the utility failed at 6 p.m. on a cold Friday, what would the household notice immediately, what would fail overnight, and what would become a problem by Sunday?

Test the handoff, too.

If one person normally handles the generator, boiler, well, alarm or network, ask whether someone else could operate the household safely if that person were away. The equipment may be fine; the single point of failure may be knowledge.
