Towers EC installs standby generators across Napa: downtown and Old Town homes, the estates up in the hills, and the wineries and tasting rooms that cannot afford to lose refrigeration or production. Master Electrician CA Lic. 847255. Every install permitted through the City of Napa or Napa County, sized to the real load, and tested before we leave.
Napa sits squarely inside PG&E’s Public Safety Power Shutoff footprint. When you call Towers EC, you get Steve Torres, who built server rooms that could not go dark for a second and now brings that same standard to backup power for your home or business.

- Transfer switch installed right: no back-feed onto the utility line, labeled and tested.
- Permitted and inspected: City of Napa or Napa County, documented for insurance and resale.
- Lifetime warranty on install labor: if our installation fails, we come back. No charge.
How A Napa Standby Install Comes Together
A generator is only as good as the load calculation, the transfer switch, and the install behind it. We treat all three as the job, not the box on the pad. Full generator details.
List The Loads That Matter
Well pump, refrigeration, the wine-cellar cooler, medical equipment, the home office, or a winery’s production and point-of-sale. We start from what you actually need running through a shutoff.
Size For The Real Demand
We size the unit to carry that load with margin, accounting for the starting surge of motors like the well pump and AC compressor. Undersized is worse than no plan.
Install, Permit, Test
Set the pad, run gas or propane and electrical, install and label the transfer switch, then commission under load and pass the City of Napa or Napa County inspection.
Frequently Asked Questions About Napa Generator Installation
Does Towers EC serve Napa, CA?
Yes. Based in Vacaville, we install generators throughout Napa and Napa County: downtown, Old Town, Browns Valley, Alta Heights, the hillside estates, and the wineries. Napa sits inside PG&E’s Public Safety Power Shutoff footprint, so backup power is not a luxury here, it is planning. Call (707) 803-6332 or email storres@towersec.net.
Will a standby generator keep my Napa home running during a PSPS shutoff?
Yes. That is exactly what these systems are built for. When the wind is high and fire risk climbs, PG&E de-energizes lines across the valley, and Napa is inside that footprint every fire season. A properly sized standby generator with an automatic transfer switch detects the outage, starts, and switches your home over within seconds, all on its own. When utility power returns, it switches back and shuts down. Through the entire shutoff, your home keeps running.
What size generator do I need for my Napa home or winery?
It depends on what you actually need to keep running, not on a number off a box. We start by listing the loads that matter: heat or AC, the refrigerator and freezer, the well pump on hillside properties, a wine-cellar cooler, medical equipment, or in a winery or restaurant the refrigeration and point-of-sale systems. Then we size the unit to carry that load with margin, because a generator undersized for the real demand is worse than no plan at all. We scope the whole thing for free and give you a straight number.
Why does the transfer switch matter so much?
The transfer switch is the safety heart of the install. It isolates your home or building from the utility line when the generator is running, so power cannot back-feed onto the grid and injure a PG&E lineworker restoring service. A generator wired without a proper transfer switch is a serious hazard and will not pass inspection. We install the switch correctly, label it, and test the whole system under load before we leave.
Do you pull permits for generator work in Napa?
Yes. We pull the permit through the City of Napa building department, or Napa County for properties outside city limits, connect the natural gas or propane feed, and pass the inspection before the job is called done. That inspection record matters for your insurance and at resale. Installation labor also carries a lifetime warranty. Call (707) 803-6332.

Backup Power, Sized And Wired For Napa’s Fire Season
A generator is only as good as the load calculation, the transfer switch, and the install behind it. We treat all three as the job, not just the box on the pad.
Outages in and around Napa come from a few directions, and the biggest one is deliberate. During high-wind, high-fire-risk events, PG&E runs Public Safety Power Shutoffs across the valley to keep lines from sparking, and Napa sits inside that footprint every season. Add summer heat straining the grid and winter storms taking down lines, and an extended outage stops being rare. For a hillside home with a well pump, a household with medical equipment or a freezer full of food, or a winery with refrigeration and production that cannot pause, an extended shutoff is a real loss. That is what a properly installed standby generator is for. It watches the utility line, starts on its own when the power drops, carries the loads you told it to carry, and shuts down when the grid comes back, all without anyone running outside in the dark to flip a switch.
Sizing Is The Whole Game
The most common mistake we fix on generator jobs is a unit that was sized off a guess. Too small and it cannot carry the real load, so it overloads and shuts down exactly when you need it. We start by listing what you actually need to keep running, then size the generator and the transfer setup to carry that load with margin, accounting for the starting surge of motors like the well pump, the AC compressor, and refrigeration. For a home that might be a focused list of essential circuits. For a Napa winery or restaurant it might be the whole panel, plus the walk-in cooler and the production line. Either way, you get a number we can stand behind, not a sales pitch for the biggest unit on the lot.
Fuel, Placement, And Installed To Code
A few practical things decide how a Napa install goes. Fuel comes first: if the property has a natural gas line, a standby unit can tie into it and run without a tank to refill; where there is no gas service, common on the hillside and vineyard lots, propane is the answer, with a tank sized for the length of outage you want to cover, and a fire-season shutoff can run a couple of days. Placement is next, meeting code clearances from windows and the meter, keeping noise away from bedrooms and neighbors, and giving a clean run for the gas and electrical. Then we set the pad, run the connections, install and label the transfer switch so the system cannot back-feed the utility line, and commission the generator under actual load. We pull the permit through the City of Napa or Napa County so the install is documented and signed off. The homeowners and winery owners who are glad they have a generator almost always installed it in a calm month, not during an outage.
Standby Or Manual Transfer
Not every Napa property needs a full automatic standby system, and part of the free scope is telling you which fit is honest for your situation. A whole-home or whole-winery standby unit with an automatic transfer switch is the right answer where an outage cannot be allowed to interrupt the operation: a home with a well and a cellar, a restaurant with a walk-in, a winery with production. It starts on its own and carries the load without anyone present, which matters when a shutoff hits while you are away. For a smaller home, or a budget that is not ready for a full standby install, a manual transfer setup lets you connect a portable generator safely to the circuits that matter through a properly installed and labeled transfer switch, so you still never back-feed the utility line. Both are legitimate. What is never legitimate is a generator plugged in without a transfer switch, and that is the one setup I will not do. On a hillside estate the automatic standby almost always wins because the loads and the stakes are high; on a modest downtown home the manual option can be the sensible first step.
Whichever route fits, the honest first step is the same: a free on-site scope and a real load calculation, so the number and the plan are in writing before anything is ordered. Installation labor carries a lifetime warranty. If our installation fails, we come back at no charge. Call (707) 803-6332 for a free on-site scope, or send the details through our contact page.
