What Drives the Cost

What Sets the Price

These six things decide the size of the job.

Portable or Standby

An inlet box and interlock for a portable generator is the smallest job. A standby generator with an automatic transfer switch is the largest.

Generator Size

A generator for heat, the fridge, pumps and lights is smaller than one that runs the whole house with electric heat.

Transfer Switch

An interlock kit costs the least. A manual transfer switch costs more, and an automatic switch for the whole house costs the most.

Fuel

Natural gas uses the line you have. Propane needs a tank. A long gas run adds to the project.

Placement

A standby generator sits outside on a pad, clear of windows, doors and vents. A spot far from the panel and the gas meter means longer runs.

Your Panel

A full or outdated panel may need work first. Load management lets a smaller generator carry a house with big loads.

FAQ

Common Questions

Four things set the price: the size of the generator, how much of the house it backs up, the distance to the panel and the fuel line, and whether the panel needs work. We check your panel, fuel options and power needs first. The exact price comes upfront, and you approve it before any work starts.

A portable generator connected through an interlock kit and an inlet box. It is the lowest-cost legal hookup, and it can power any circuit in the panel within the size of the generator.

It depends on what you want powered. Critical circuits need a smaller generator than a whole home. We run a load calculation and recommend a size.

Yes. Whole-home backup needs a larger generator and a transfer switch rated for the full service. Backing up chosen circuits, or adding load management, keeps the generator smaller.

Natural gas, when the house already has a line. Propane adds a tank outside. Either way the fuel connection needs a mechanical permit, which we handle.

Yes. An electrical permit, plus a mechanical permit for the gas connection. We handle the permits and inspections.

Usually not. A full or outdated panel may need work first, and we tell you during the home assessment.
