Spark Shark Electric in Moore, Oklahoma installs whole-home Generac standby generators for OKC-metro homeowners. Oklahoma weather doesn't ask permission — ice storms, line-of-thunderstorms, tornadic systems, and prolonged grid outages. A whole-home standby generator powered by natural gas or LP starts within seconds of a power loss and runs your house until the grid comes back. We size it, install the automatic transfer switch, pull the permits, and commission the system end-to-end.
What we install
- Whole-home Generac standby generators: natural gas or LP, sized to your load (commonly 14kW–26kW for OKC-metro homes).
- Automatic transfer switches (ATS) sense the outage and start the generator within seconds.
- Sub-panels for managed loads: optional, for homes where running everything at once would oversize the unit.
- Wi-Fi monitoring: see status and run history from your phone.
- Annual maintenance: oil change, filter, exercise-mode test, transfer-switch verification.
Why a standby generator in Oklahoma
- Ice storms routinely take down lines across the OKC metro for days at a time.
- Severe and tornadic storms cause localized outages that aren't always priority restoration zones.
- Summer heat advisories put grid load at peak, and outages during a heat event are a medical risk for anyone with health vulnerabilities or small children at home.
- Whole-home backup keeps HVAC, refrigeration, well pumps, sump pumps, internet, and medical equipment running without anyone touching anything.
How we size a generator
- We look at your service size, the breakers you actually use, and which loads matter when the power's out.
- Critical loads (HVAC, fridge/freezer, kitchen, lighting, internet) come first.
- Optional loads (electric vehicle charging, pool equipment, large workshops) are layered in or load-managed.
- We don't oversell. A too-large generator costs more, uses more fuel, and runs less efficiently.
How the install runs
- Day one: generator pad set, gas line tied in by a licensed plumber (we coordinate), ATS wired into your panel.
- Day two: commissioning (load-bank test, ATS dry-run, automatic transfer test, manual override test).
- Same day as commissioning: walkthrough on monitoring, exercise schedule, and what to expect during the next outage.
- Permit pulled on every install. Inspection scheduled.
Generators are part of a complete residential electrical system
- A generator install often pairs with a panel upgrade. Spark Shark Electric handles both, and we'll cross-quote the panel and the generator in a single written estimate so you can plan the project once.
- Annual maintenance keeps the unit ready for the day it actually has to run. We offer maintenance plans on units we install.
Common questions
How long can a standby generator run?
On natural gas, indefinitely — as long as utility gas keeps flowing, the generator runs. On LP, runtime depends on tank size; a 500-gallon tank typically supports 5–10 days of full-load operation.
Do I need a permit?
Yes. Generator installs require both an electrical permit and (typically) a gas permit. Both are pulled by us as part of the job.
How loud is it?
Modern enclosed standby generators are roughly 65–70 dB at 23 feet, about as loud as a window A/C unit. Setback distances from windows are dictated by code; we handle siting.
How much does a whole-home generator install cost in Moore or OKC?
It depends on generator size, gas-line work, ATS complexity, panel modifications, and any pad/site prep needed. After a free site visit, we give you a written flat-rate quote, with no hidden fees and no add-ons after the fact.
Do I need to upgrade my electrical panel before installing a generator?
Sometimes. Older or undersized panels often need a service upgrade to support a whole-home generator. We assess your panel during the site visit and bundle any required work into one written quote.
