Notes

  • Where the number comes from. The national price for an 18 kW standby generator installed is $11,500 installed — standby generator pricing published for 2026, unit plus installation. Labor is about 45% of that. Electricians near Tri-Cities, WA average $94,470 a year against a U.S. mean of $71,490 — a factor of 1.321 — so the labor half is scaled by that and the material half is not. Source: BLS does not publish a metro figure for electricians near Tri-Cities, WA, so this is the Washington state average, SOC 47-2111.
  • This one falls back to a wider average. BLS did not publish a metro-level wage for this trade near Tri-Cities, WA, so the figure above is a state average. It is still the right order of magnitude, but a local bid carries more weight here than it would in a large metro where the survey has more responses.
  • What is in the price: the generator, a concrete or composite pad, the transfer switch, electrical connection, gas piping from an existing supply, permit and commissioning.
  • What is not: a propane tank and its burial, a gas meter upsize where the utility requires one, trenching over long distances, and the annual service contract. These are the lines that turn a $13,163 quote into a $16,454 invoice, so ask about each one before signing.
  • Use this as a bid check, not a quote. It prices an average job in average condition. Difficult access, the state of what is being replaced, the season, and a crew booked out three months all move the real number, and none of them are in a national average for the job.

$13,163 is the typical number, and three bids on the same scope normally land between $9,730 and $17,742.

Why the city changes the number

About 45% of this job is labor — $5,924 of the $13,163 above. Labor is the only part that moves locally; a bundle of material costs what it costs wherever it is nailed down.

Electricians near Tri-Cities average $94,470 a year, against a U.S. mean of $71,490. That is a factor of 1.321, so the labor half is scaled by it and the material half is not.

What the quote should include

The lines that turn a quote into an invoice

Ask about each of them before you sign. On a job this size they are the difference between $13,163 and something a quarter higher.

Use it as a bid check, not a quote

This prices an average job in average condition. Access, the state of what is being replaced, the season, and a crew booked out three months all move the real number, and none of them are in a national average.

If a bid lands outside $9,730 – $17,742, that is not automatically wrong — but it is the question worth asking out loud.
