Backup Power for Bay Area and North Valley Businesses
PG&E PSPS shutoffs, transformer failures, and storm outages can take a Bay Area or Butte County facility offline for hours or days. Every minute of downtime costs revenue, inventory, or compliance posture.
A right-sized commercial standby generator keeps payroll, HVAC, refrigeration, security, POS, and life-safety systems running while the grid is down. We design, install, and maintain systems that match your load and your local code.
Jackson Electric installs and services Generac, Kohler, Winco, CAT, and Cummins commercial standby systems. Same-day emergency generator service is often available for businesses across San Jose and Chico, CA.
Industries We Power Through Outages
From walk-in coolers to dental chairs to security systems, every minute of downtime hits the bottom line. We size and install commercial generators for businesses across our commercial services portfolio.
Restaurants and Food Service
Walk-in coolers, freezers, fryers, POS, and exhaust hoods stay online. Avoid spoiled inventory and missed covers when the grid drops.
Healthcare and Dental Offices
Operatory chairs, sterilizers, refrigerated meds, HVAC, and patient records stay powered through PSPS events. Compliance and patient safety protected.
Retail and Dispensaries
Lighting, security cameras, climate-controlled product, and POS keep operating. Storefronts stay open for sales, dispensaries stay compliant on inventory tracking.
Light Manufacturing and Machine Shops
CNCs, presses, dust collection, and finishing booths can run on essential-load coverage so production schedules survive a grid event.
Multi-Tenant and HOAs
Lobbies, elevators, common-area lighting, gates, garage doors, and life-safety systems stay online for residents during PSPS or extended outages.
Gas Stations and Convenience Stores
Pumps, walk-in coolers, lighting, and POS keep operating so the station stays open and revenue keeps flowing through a grid outage.
Generator Types and Fuel Options
Choosing the right fuel and configuration is a real decision. Each option has trade-offs in fuel logistics, runtime, footprint, and total cost. We walk you through them on every assessment.
Natural Gas
The most common pick when utility gas is available. No on-site fuel storage, no refill logistics, unlimited runtime as long as the gas line stays pressurized. Ideal for most San Jose and urban Chico commercial sites.
Diesel
Highest energy density per gallon, common at 100kW and above. The right pick for manufacturing, larger multi-tenant, and any facility where a long runtime on stored fuel is required. Fuel polishing and storage maintenance matter.
Propane (LPG)
The right answer for rural Chico and Butte County sites without natural gas service. Propane stores cleanly for years and works well for small to mid-size commercial loads.
Bi-Fuel
Combines diesel and natural gas for extended runtime on critical loads. Ideal where utility gas may be interrupted but extended runtime on stored fuel is also required. Common on data closets, healthcare, and large multi-tenant sites.
How We Size Your Generator and Transfer Switch
Sizing depends on the loads you actually need to keep running. We perform a free on-site load assessment and walk through two questions with you: which loads must stay live during an outage, and how do those loads start (motor starting, HVAC inrush, refrigeration compressors). The answer drives generator kW, fuel choice, and transfer switch configuration.
Whole-Facility vs Essential-Load Coverage
Whole-facility coverage backs up your entire service. Essential-load coverage backs up a subpanel that holds only the circuits you cannot afford to lose. Essential-load is often the right call when budget or footprint is tight, and a commercial panel upgrade is sometimes paired with a generator install when service capacity has been reached.
Automatic Transfer Switch (ATS) Options
An automatic transfer switch senses utility loss and switches the panel to generator power in seconds without anyone touching a breaker. We install service-entrance ATS for whole-facility coverage and branch-level ATS for essential-load designs. Open-transition is standard. Closed-transition transfer is available where seamless switching is required.
Brands We Install and Service

Our Commercial Generator Installation Process
Every commercial standby project follows the same disciplined sequence so there are no surprises on permit, schedule, or cutover day.
1. Free Load Assessment
A licensed electrician walks the facility, identifies essential loads, measures starting and running amps, and confirms gas or fuel availability.
2. Sizing and Written Proposal
We deliver a written proposal with generator make and model, fuel option, transfer switch configuration, site prep scope, and a clear price.
3. Permits and AHJ Coordination
We pull electrical, mechanical, and gas permits and coordinate with your local AHJ in San Jose, Santa Clara County, Chico, or Butte County.
4. Site Prep, Install, and ATS Wiring
Concrete pad, gas line, and conduit runs are prepared. Generator is set, ATS is wired in, and the system is integrated with your existing service or essential-load subpanel.
5. Commissioning and Operator Training
Final inspection, load bank test, and commissioning. We walk your operations team through start, transfer, and routine checks. The unit is ready for the next outage.
Commercial Generator Installation in San Jose, CA
San Jose runs on dense commercial corridors from Santana Row to East San Jose, North San Jose tech, and Almaden. PG&E PSPS events, transformer faults, and storm outages all hit the South Bay every year. Our San Jose office handles permit coordination through City of San Jose and Santa Clara County for commercial standby installs across restaurants, dental, retail, multi-tenant, and small manufacturing facilities. Call our San Jose team at (408) 266-5351 for a free on-site assessment.
Commercial Generator Installation in Chico, CA
Chico, Paradise, Magalia, and Oroville all sit inside PSPS country. Wildfire risk and rural transmission make backup power a serious operating decision for North Valley businesses. Many rural Butte County sites do not have natural gas service, so propane standby is often the right answer. Our Chico team coordinates Butte County and City of Chico permits for commercial generator installs and provides emergency repair when an existing unit fails to start during an outage. Same-day service is often available. Call Chico at (530) 907-7961 for a free on-site assessment.
Why Bay Area and North Valley Businesses Choose Jackson Electric
Operational Continuity
Keep critical systems running through PG&E PSPS events, transformer failures, and storm outages so payroll, HVAC, refrigeration, security, and POS never go offline.
Lower Total Outage Cost
A right-sized standby generator pays back fast on a single outage by protecting inventory, billable hours, and tenant retention. Restaurants alone can lose thousands per day in spoilage and missed covers.
Code-Compliant on Day One
We pull the permits, coordinate with your local AHJ, and commission to applicable California Building Code and NEC requirements. Final load bank test and commissioning included on every install.
