Power Through Every Storm. Instantly.
Whole-home standby generator installation across the OKC metro. Licensed installer for Generac, DuroMax, and Kohler, with every permit pulled and every install done to code.
Oklahoma weather doesn't give warnings.
Ice storms shut down the metro for a week at a time. Tornado season knocks out service to entire neighborhoods. Severe summer thunderstorms drop power lines across the OKC metro every year, and every year, OG&E restoration times stretch into days.
A whole-home standby generator changes that calculation entirely. The moment grid power drops, your generator kicks on automatically. No manual switches, no extension cords, no waiting in the dark.
For Oklahoma City homeowners, it’s no longer a luxury. It’s how you protect everything that runs on power: your food, your medical equipment, your HVAC, your security system, and your family’s comfort during the storms this state is known for.

For a standby generator to start and power your home after the grid goes down
What a whole-home standby generator actually does.
A standby generator is permanently installed outside your home, connected to your natural gas or propane supply, and wired through an automatic transfer switch directly into your electrical panel. When grid power drops, your generator detects the outage within seconds and starts supplying power: whether you’re home, away, or asleep.

How does Kelvin Electric charge for service calls and quotes?
A service call is $175, plus any parts, and we aim to fix the problem within the first hour. If it looks like the job will run past an hour or is more than a quick fix, we stop, explain what we found, and you decide what happens next. If we need to quote in person, the visit is $175, and it is credited toward the work if you choose to move forward.
How long does a generator installation take?
Most whole-home standby generator installations are completed in one to two days, depending on site complexity and permit processing time. Critical-circuit installs are often finished in a single day.
Do I need a permit for a generator in Oklahoma City?
Yes: generator installations in Oklahoma City require electrical permits and inspections. Kelvin Electric pulls every required permit as part of our standard installation process and coordinates the final inspection. You don't have to handle any of the paperwork.
What fuel does a standby generator use?
Most standby generators in Oklahoma City run on natural gas. Most OKC homes are already piped for it, making this the most convenient option. Propane is also widely supported, particularly for properties without natural gas service. We help you decide which fuel source makes the most sense during your consultation.
Will a standby generator power my whole house?
It depends on the size of the unit. We offer solutions ranging from critical-circuit coverage (essentials like HVAC, refrigeration, and lighting) to true whole-home standby power. During your quote visit, we calculate your home's load and help you decide what level of coverage makes sense for your needs and budget.
How much maintenance does a standby generator need?
Standby generators need routine maintenance to operate reliably: typically an annual service that includes oil changes, filter replacements, and a test cycle. Kelvin Electric offers ongoing maintenance plans so your generator is ready every storm season without you having to think about it.
Do you offer financing for generator installations?
Yes. We offer financing for qualified customers on larger projects, including generator installations. We're happy to walk through your options during the consultation so you can find an arrangement that fits your budget.
What size generator do I need for my home?
Sizing depends on your home's square footage, HVAC system, kitchen appliances, and which circuits you want backed up. As a rough guide: a small home with critical-circuit coverage might need a 12 to 14kW unit, while a larger home with whole-home coverage might need 22kW or higher. We calculate this precisely during your quote visit.
What areas do you serve for generator installation?
We install generators across the entire OKC metro, including Oklahoma City, Edmond, Norman, Moore, Yukon, Mustang, Midwest City, Del City, Bethany, Warr Acres, Nichols Hills, Arcadia, Piedmont, and The Village. Not sure if we cover your area? Just call: chances are we do.
