Standby Power for Seattle Homes

Generator Installation in Seattle, WA

Konsker Electric installs whole-home standby generators for Seattle, WA homes, licensed and bonded through Washington State L&I with a BBB A+ rating and more than 20 years in the metro. When the power goes out in a windstorm and you want backup that turns on by itself, we size the generator to your Seattle home's real critical loads with a load calculation per NEC Article 220, set the pad, wire the automatic transfer switch at your service, coordinate the gas-meter sizing with Puget Sound Energy, and pull the Seattle DCI electrical permit so the system passes inspection on the first visit. You get a flat-rate quote in writing before any work begins, so the number you see is the number you pay.

A note on what makes Seattle different from the rest of the metro: inside city limits the electrical permit goes through Seattle DCI, not Washington State L&I, and the electric utility is Seattle City Light rather than Puget Sound Energy. The gas that fuels most standby units still comes from PSE. Getting those two authorities right on the paperwork is exactly the kind of detail that keeps an install from stalling at inspection.

What It Costs

Standby Generator Installation Cost in Seattle

Whole-home standby generator projects are estimate-driven, not flat-priced. We do not publish a single sticker number because the honest answer depends on the variables below, and quoting a number before the load assessment would be guessing. After a site walk you get a flat-rate quote in writing, and that is the number you pay.

One factor sets the floor more than any other: whether your existing Seattle City Light service can carry the new load. Newer construction in Ballard and the mixed-use infill along the light-rail corridor usually runs a 200-amp service with headroom, while the pre-1960 bungalows and boxes in Wallingford, Queen Anne, and the Central District often still run a 100-amp service and need a Seattle panel upgrade first. We tell you which camp your home is in before you commit.

Whole-Home Standby Generator Sizing

Load Calculation, Not a Brochure Number

The right unit is sized to your home's critical loads, not to a spec sheet. Here is what actually matters for Seattle's tree-canopy neighborhoods and wet winters.

Outage frequency, not just length

Seattle City Light overhead feeders through the tree-canopy neighborhoods of Broadview, Laurelhurst, Magnolia, and Wedgwood take limb-on-line hits during Puget Sound windstorms. Size for the loads you cannot lose for two to three days, not for a one-hour blip.

Load-managed over oversized

A load-managed transfer switch lets a right-sized 18 kW to 24 kW unit carry a heat pump, refrigeration, and a sump or crawlspace pump through Seattle's wet winter without nuisance trips. Oversizing just burns fuel and budget.

Natural gas where PSE serves it

Most Seattle homes already have a Puget Sound Energy gas service, so a natural-gas standby never needs refueling. We coordinate the meter sizing with PSE directly so the meter can carry the added generator load.

When a whole-home standby is the wrong call

If you lose power once or twice a year for an hour or two and all you really care about is keeping the fridge and a few lights alive, a whole-home standby is more system than you need. A portable generator with a properly wired interlock kit, or a smaller managed essential-circuits transfer switch, will cover you for a fraction of the cost. We will tell you that on the site walk instead of selling you the biggest unit on the truck. The standby makes sense when you have a well pump, a medical device, a work-from-home setup you cannot lose, or a wooded lot where outages run for days, not hours.

We install Generac, Kohler, and Briggs and Stratton standby generators across Seattle, and we coordinate the interconnection and meter work with the same generator crew that handles our commercial standby systems. The difference for a home is in the load math, not the brand badge.

Permits & Utility Coordination

Seattle DCI, Seattle City Light, and PSE, Handled for You

Inside Seattle city limits the paperwork touches three authorities, and getting all three right is what keeps a generator install on schedule. As an electrical contractor licensed through Washington State L&I, we pull the Seattle DCI electrical permit, coordinate any service work with Seattle City Light, and handle the Puget Sound Energy gas-meter sizing. We do not leave the utility calls to you.

Electrical permit filed with Seattle DCI, the permitting authority inside Seattle city limits
Seattle City Light coordination for any disconnect, reconnect, or service upgrade the project needs
Puget Sound Energy interconnection and gas-meter sizing coordinated directly, since a standby unit adds load the meter may not be sized for
Whole-home Type 2 surge protection at the service per NEC 230.67, standard on every generator install
Full-load commissioning test and Seattle inspection sign-off before the system is handed over

Whether your home is a Laurelhurst waterfront property, a Magnolia bluff house, or a Wallingford bungalow that needs a panel upgrade first, this is work we do across the city. We also provide whole-home generator backup for Seattle outages through the same 24/7 emergency crew, and generator installation across the Seattle metro for the surrounding suburbs. Prefer to talk it through now? Call (206) 260-1981.

Many older Seattle homes need a 200-amp service before the generator. We do both in one project.

Common Questions

Seattle Generator Installation FAQ

Does a standby generator need a permit in Seattle?

Yes. A whole-home standby generator is an electrical permit job inside Seattle city limits, and that permit runs through Seattle DCI (the Department of Construction and Inspections), not Washington State L&I, because Seattle is its own electrical authority. As an electrical contractor licensed through Washington State L&I, we pull the Seattle DCI electrical permit, schedule the city inspection, and coordinate the Seattle City Light and Puget Sound Energy work. The automatic transfer switch, the service bonding, and the disconnect all have to pass Seattle inspection before the system is energized, so this is not a job that should go in unpermitted. Seattle also enforces its own local amendments on top of the 2023 NEC, which is one more reason to have the permit handled by someone who works inside the city every week.

How long does generator installation take in Seattle?

The on-site electrical work for a typical Seattle whole-home standby install runs one to two days once everything is staged: pad set and cured, generator placed, automatic transfer switch wired in at the service, and the natural-gas line tied to the Puget Sound Energy meter. The longer part of the calendar is the lead time before that install day. That window covers the Seattle DCI permit, the PSE gas-meter sizing coordination, and generator availability on the model you choose. If your existing service also needs a panel upgrade first, a Seattle City Light service application can add several weeks to that front-end timeline. We give you the realistic full schedule in the written quote, not just the one or two day install window.

How do I size a whole-home standby generator for a Seattle house?

Sizing starts with a load calculation per NEC Article 220, not with a brochure number. We meter your service and add up the circuits you actually cannot lose during a multi-day outage: the heat pump or furnace blower, refrigeration, the sump or crawlspace pump, well pump where present, and home-office power. Most Seattle single-family homes land in the 18 kW to 24 kW range on a Generac, Kohler, or Briggs and Stratton air-cooled standby running on natural gas, with a load-managed automatic transfer switch so a right-sized unit carries the heavy loads without nuisance trips. Older Wallingford, Ballard, and Queen Anne homes that still run a 100-amp service usually need a service upgrade before the generator, which is a separate line item we flag up front.

What is the best standby generator for Seattle windstorm outages?

For the tree-canopy neighborhoods of Seattle (Broadview, Laurelhurst, Magnolia, and the wooded stretches of West Seattle and Wedgwood), the right unit is the one sized to your home's critical loads and fed by fuel you never have to refill. Seattle City Light overhead feeders in these leafy neighborhoods take limb-on-line hits during the November and December windstorms that blow through the Puget Sound lowlands, and those outages routinely run a full day or longer. A natural-gas standby in the 18 kW to 24 kW range with a load-managed transfer switch keeps a Seattle home warm and dry through that without a fuel run to the gas station. The brand matters less than the load math and the fuel source.

How much does standby generator installation cost in Seattle?

Whole-home standby generator projects are estimate-driven, not flat-priced, because the honest number depends on the generator size, the distance from the panel to the pad, the gas-line run length, and whether your existing Seattle City Light service and PSE gas meter can carry the added load without an upgrade. We give every Seattle homeowner a flat-rate quote in writing after a load assessment and a site walk, so the number you see is the number you pay. There are no surprise change orders mid-install.
