Commercial Generator Installation Redding, CA
Addy Solar & Electric provides commercial generator installation in Redding, CA for businesses and facilities that cannot afford to lose power. We install standby generator systems that activate automatically during grid outages, keeping your operations running without interruption.
How Commercial Standby Generators Work
A commercial standby generator is a permanently installed unit connected to your building through an automatic transfer switch. It runs on natural gas, propane, or diesel and monitors the grid 24/7. When power fails, it starts within seconds and keeps your facility running without manual input.
When utility power returns, the system switches back and shuts down automatically. It also performs regular self-tests to stay ready for the next outage.
- Automatic startup within seconds of a power outage
- Runs on natural gas, propane, or diesel for continuous operation
- Powers your entire facility or selected critical systems
- Automatic transfer switch handles all grid transitions
- Weekly self-test cycle keeps the system ready at all times

The Cost of Downtime vs. The Cost of a Generator
A power outage does not just turn off the lights. It stops production, kills point-of-sale systems, shuts down refrigeration, disables security, and sends customers and employees home. For most businesses, the cost of one extended outage exceeds the cost of a generator.
Lost Revenue During Outages
Every hour without power is an hour without sales, production, or service delivery. For a restaurant, retail store, or service business, that can mean thousands of dollars in lost revenue per outage.Â
A standby generator eliminates that exposure entirely by keeping your doors open and your systems running.
Spoiled Inventory & Damaged Equipment
Businesses that depend on refrigeration, climate control, or continuous process equipment face real financial losses when the power goes out.Â
Spoiled food, compromised pharmaceuticals, interrupted manufacturing runs, and damaged server hardware can cost far more than the outage itself.Â
A generator protects your inventory and equipment around the clock.
Safety & Liability Risks
A dark building is a liability. Emergency lighting has a limited battery life. Exit signs go dark. Security cameras and access control systems stop working.Â
For businesses with employees or public access, a prolonged outage creates real safety and legal exposure. A generator keeps your safety systems operational throughout the event.
Business Continuity & Reputation
Customers and clients expect you to be available. If an outage shuts you down while competitors across town stay open, that is a reputation hit you may not recover from.Â
A standby generator makes your business the one that stays open when others cannot.
Choosing the Right Commercial Generator
facilities. Choosing the right one depends on your electrical load, fuel access, and how much of your operation you want to keep running during an outage.
Generator Sizing For Your Facility
Undersizing a commercial generator means critical systems get dropped during an outage. Oversizing wastes money on equipment capacity you never use.Â
We perform a detailed load analysis of your facility, accounting for startup surge loads from HVAC compressors and motors, to recommend a generator that matches your actual demand.
Fuel Type Options
Natural gas generators connect to your existing gas line and provide unlimited runtime as long as gas service is maintained.Â
Propane requires a dedicated storage tank but works in areas without gas service. Diesel is common for larger industrial applications and offers high power density.Â
We recommend the fuel type based on your location, facility size, and runtime requirements.
Full Facility vs. Critical Load Coverage
Not every business needs to power the entire building during an outage. A critical load setup powers only the systems that matter most, like server rooms, refrigeration, security, and essential lighting.Â
This uses a smaller and less expensive generator while still protecting the parts of your operation that cannot go down.
Placement, Noise, & Permitting
Commercial generators need to meet setback requirements, noise ordinances, and local building codes.Â
Placement depends on fuel connections, electrical routing, ventilation, and access for maintenance.Â
We handle site planning, permitting, and compliance so the installation meets all local requirements without delays.
How We Install Your Commercial Generator
01
Load Analysis
We analyze your facility’s electrical load, identify critical systems, and calculate total demand including startup surge. This determines the right generator size and configuration for your business.
02
Equipment & Site Prep
We order the generator, prepare the concrete pad or mounting location, and pull all required permits. Fuel line connections and electrical routing are planned in advance.
03
Installation & Wiring
We set the unit, run the fuel line, install the automatic transfer switch, and connect the generator to your building’s electrical system. All work is done by our licensed electricians.
03
Commission & Test
We run a full load test to simulate an outage and verify automatic startup, power transfer, and shutdown. We configure the weekly self-test schedule and walk your team through the controls and monitoring.

Transfer switch installation, panel work, and all wiring are handled by our licensed C10 electricians. One team, one contract, one point of accountability for the entire project.
Frequently Asked Questions
How much does a commercial generator cost?
Commercial generator installations typically range from $50,000 to $100,000 or more depending on generator size, fuel type, electrical complexity, and site preparation.Â
A small office might need a 20-30 kW unit on the lower end. A large facility with full building coverage will be on the higher end.
We provide a detailed quote after completing a load analysis of your facility. Request more info to schedule a site visit.
How quickly does a standby generator start during an outage?
Most commercial standby generators start and transfer power within 10 to 30 seconds of detecting a grid failure.Â
The automatic transfer switch handles the entire process without any manual intervention. For facilities that need even faster response, uninterruptible power supply (UPS) systems can bridge the gap during startup.
We configure the transfer switch and startup sequence during commissioning to match your facility’s needs.
What fuel type is best for a commercial generator?
Natural gas is the most convenient for facilities with an existing gas connection because it provides unlimited runtime.Â
Propane works well in areas without gas service and requires a dedicated storage tank. Diesel is preferred for larger industrial generators due to its high energy density and fuel availability.
We recommend the best fuel option based on your location, facility size, and expected backup duration.
Does a commercial generator require regular maintenance?
Yes. Commercial generators need regular maintenance including oil changes, filter replacements, coolant checks, and load bank testing.Â
Most manufacturers recommend service every 6 to 12 months depending on usage. The generator also runs a weekly self-test to keep the engine and battery ready.
Addy Solar & Electric offers maintenance support to keep your generator ready when you need it.
Can a generator work alongside solar and battery systems?
Yes. We design backup power systems that layer solar, battery, and generator together.Â
Solar charges the battery during the day, the battery handles short outages and peak shaving, and the generator kicks in for extended events when the battery runs low.Â
This gives you the most complete and cost-effective backup strategy available.
We handle all three systems under one contract so everything is designed and wired to work together seamlessly.
