Temporary Power in Napa
Temp poles, spot coolers and site internet for Napa winery, hospitality and home projects, set up by our crew from San Rafael.
Getting to Napa jobs on Highway 37
Napa is in Napa County, east of Marin. Our crews come from San Rafael, usually on Highway 37 along the top of San Pablo Bay, so Napa is part of our extended service area. Traffic on 37 can crawl at commute hours, and we set install times with that in mind. A site walk booked a few days ahead lets us pair it with other trips east.
Work in and around Napa is a mix of winery buildings, hotels and restaurants, and houses. A production building or tasting room may need three-phase service for pumps, chillers and lifts, while a remodel in an older neighborhood often runs fine on a 100A pole. Hospitality jobs tend to have fixed opening dates, so the PG&E timeline needs attention early.
In Napa the wires and the meter belong to PG&E. Many local accounts get their generation from MCE, and that name shows up on the bill, but PG&E is still where the temporary service application is sent. We file it as soon as the electrical permit number comes through and keep checking until a meter date is on the calendar.

Common orders on Napa sites
Three-phase for winery buildings
Crush pads, barrel rooms and production spaces run motors that want three-phase power. Temp services for winery and tasting room work cover the pole, meter base, panel, permit and inspection.
Cooling for hot afternoons
Napa summers get hot, and an office trailer or a closed-up interior can be hard to work in by 2pm. Spot coolers for a hot Napa interior keep crews comfortable, and ducted units hold a steady temperature while drywall mud or flooring adhesive cures.
Signal on rural parcels
Winery parcels outside town can be a long way from good cell coverage. Satellite or bonded cellular service on rural parcels keeps plan sets, inspection requests and video calls moving from the trailer.
What Napa temp power runs
On a Napa house or small commercial space, a 100A to 200A single-phase pole most often prices out at $1,800 to $4,500 with the install. Winery and hotel jobs on a 400A three-phase service tend to fall between $6,000 and $14,000, sometimes more. Budget about $250 to $700 per week for each spot cooler, and expect PG&E to send its fees on a separate bill.

Napa permit, flood and retrofit notes
Inside city limits, the electrical permit goes to the City of Napa building division. Parcels in the unincorporated county, which includes many winery properties, go through Napa County Planning, Building and Environmental Services, known as PBES. We confirm which office has the parcel before anything is filed.
Some Napa lots sit in the flood plain near the Napa River. On those we keep the panel and receptacles high and route cable away from low spots, and you should check the flood map for your parcel. Older buildings in town have seen retrofit work since the 2014 South Napa earthquake, so if your job includes structural changes, ask the building division what applies before the temp service plan is final.
Napa job questions
How long until a Napa site has power?
The install is one day once the permit is issued. The permit and PG&E scheduling usually take a few weeks. If the opening date is close, a generator can run the site until the meter is set.
Can you come out to Napa on short notice?
Crews leave from San Rafael, so same-day visits are harder to promise than in Marin. Call early and we will fit you into the next trip east during our Monday to Saturday, 7am to 7pm hours.
Do winery jobs in the county need a different permit?
They go to Napa County PBES instead of the city. The temp service itself is built the same way, but the application and the inspection come from the county.
