Portable now, or straight to automatic standby
Backup power comes in three tiers. A portable generator feeding a panel inlet with an interlock is the budget setup: you wheel the unit out, plug in one cord, and power the circuits you chose in advance. A manual transfer switch does the same job through a dedicated essentials panel. An automatic standby generator is the set-and-forget tier: it lives outside on a pad, watches the grid, and takes over on its own. For the fringe neighborhoods where longer outages are the pattern, that automatic response is worth real money; for closer-in homes, a portable setup often covers the actual risk.
The electrical work for a portable setup, the inlet or transfer switch, wiring, and permit, runs $800 to $2,500, with the portable unit itself typically $500 to $2,500 wherever you buy it. Standby systems run $6,000 to $15,000 and up installed. The full breakdown lives in our generator cost guide.
