Standby Generator & Backup Power Programs
A whole-home standby generator ties a licensed electrician, a gas fitter, a permitted pad, and an automatic transfer switch into your main panel. There is no federal tax credit for fuel-powered generators, but utility backup-power rebates, medical-baseline programs, and battery alternatives can offset a real share of the cost.

Why a Standby Generator Is a Multi-Trade Install
Roughly 40% of a whole-home install is the unit; the rest is the transfer switch and electrical, the gas line, the pad, and permits. It usually needs a licensed electrician and a gas fitter, plus electrical and mechanical inspections before it can run.
- An automatic transfer switch must be wired into the main panel by a licensed electrician
- Natural gas or propane supply often needs a larger line or a meter upgrade to feed the unit
- Fuel-powered generators do not qualify for the federal clean-energy tax credit
- Utility and resilience programs, and battery alternatives, are where the incentives are
Where Backup Power Support Comes From
Generator incentives are mostly local and situational — tied to outage risk, medical need, or income — rather than a single national program.
- Utility backup-power rebates in outage-prone and high-fire-risk areas
- Higher amounts for Medical Baseline and income-qualified households
- Portable generator and power-station rebates for smaller backup needs
- Battery storage — an alternative — qualifies for the 30% federal credit and SGIP
Available Incentive Programs
Backup power support is largely utility- and location-driven. These are the categories to check for your area.
Backup Power & PSPS Rebates
Utility rebates for generators and backup systems in areas exposed to Public Safety Power Shutoffs or frequent outages. Amounts and eligibility depend on your utility, your fire-risk tier, and the type of equipment.
Medical Baseline & Critical Care Backup
Programs for households that depend on electrically powered medical equipment, offering larger backup power rebates and priority support. Enrollment in a utility's Medical Baseline allowance is usually the entry point.
Income-Qualified & High-Fire-Risk Enhancements
Enhanced rebate tiers for income-qualified customers and homes in designated Tier 2 or Tier 3 high fire-threat areas, which can cover a substantially larger share of backup power equipment.
Portable Generator & Power Station Rebates
Rebates toward portable generators and battery power stations for smaller backup needs — refrigeration, medical devices, phones, and routers — typically for customers in high fire-risk or outage-prone areas.
Battery Storage as an Incentivized Alternative
Where a generator gets no federal credit, a home battery does — the 30% federal Investment Tax Credit, plus state storage rebates like California's SGIP, which reaches the highest amounts for medically vulnerable and equity-eligible households.
Local Resilience & Preparedness Programs
City, county, and regional programs — sometimes disaster-preparedness grants, sometimes utility partnerships — that support backup power for vulnerable residents. Availability is highly local.
What a Standby Generator Installation Involves
A permanently installed standby generator is electrical work, gas work, and site work together — performed by licensed trades, permitted, and inspected before it can be commissioned.
Sizing & Load Calculation
A licensed electrician runs a load calculation to decide what the generator needs to carry — the whole house, or a set of essential circuits — and sizes the unit accordingly, commonly 14 to 26 kW for a home. Undersizing leaves loads stranded during an outage; oversizing adds cost and fuel demand.
Automatic Transfer Switch
The ATS is wired between the utility service and the main panel. It senses an outage, disconnects from the grid, starts the generator, and transfers the load — then reverses when utility power returns. The grid disconnect is what protects line workers from backfeed, and it is why this is licensed-electrician work with a permit.
Pad, Placement & Clearances
The unit sits on a poured concrete or composite pad, set to the manufacturer's and code clearances from the house, windows, doors, vents, and the gas meter. Placement also has to account for exhaust direction and noise ordinances. This is often the step that dictates where on the property the generator can go.
Fuel Supply
Natural gas or propane. A licensed gas fitter ties into the meter or tank, and the line frequently has to be upsized — or the gas meter upgraded — to deliver the volume a running generator demands without starving other appliances. Propane installs add tank sizing and placement.
Electrical Tie-In & Grounding
Conductors between the generator, the ATS, and the panel; a dedicated control circuit; and grounding and bonding per NEC Article 250 and the generator sections of the code. If the existing panel is undersized or full, this is where a panel or service upgrade gets folded in.
Permits & Inspections
A standby install typically pulls an electrical permit and a mechanical or gas permit, and sometimes a building permit for the pad. The local authority having jurisdiction inspects the electrical tie-in, the gas connection, and the setback and clearances before the system is approved to operate.
Portable, Standby, or Battery — and Commissioning
A portable generator with a manual transfer switch or interlock is a smaller, lower-cost path a licensed electrician can still set up safely and legally — never through a regular outlet. A home battery covers shorter outages silently, with no fuel or exhaust, and carries the incentives a fuel generator does not. Whichever route, a permanent standby unit is commissioned after inspection: the installer confirms the automatic start, the transfer timing, and the exercise schedule, and sets the maintenance interval.

Frequently Asked Questions
Is there a federal tax credit for a home generator?
Not for fuel-powered standby or portable generators — they don't qualify for the federal clean-energy credit. A home battery storage system does: it's eligible for the 30% federal Investment Tax Credit, and often for state storage rebates as well. If incentives are a priority, comparing a battery against a generator is worth doing early.
Do I need a permit to install a standby generator?
Yes. A permanently installed standby generator typically requires an electrical permit and a mechanical or gas permit, and sometimes a building permit for the pad. The local authority having jurisdiction inspects the electrical tie-in, the gas connection, and the clearances before it can be commissioned. Portable generators used with a proper transfer switch or interlock still need that switch installed under permit.
What size generator does a house need?
It depends on whether you want whole-house coverage or a set of essential circuits, and on your largest loads — air conditioning, well pump, electric range, heat pump. A licensed electrician's load calculation sizes it, commonly landing between 14 and 26 kilowatts for a home. Sizing to essential circuits only can significantly reduce the unit and fuel cost.
Natural gas or propane?
Natural gas runs off your existing utility supply with no tank, but the line or meter often has to be upsized to feed the generator. Propane needs a tank sized and placed on the property but works where there's no gas main. A licensed gas fitter evaluates supply volume either way — a generator that starves other appliances of gas isn't a working install.
What does the transfer switch do, and can I skip it?
No. The transfer switch disconnects the house from the grid before the generator powers it, which is what keeps generator power from backfeeding onto utility lines and endangering line workers. An automatic transfer switch does this on its own during an outage; a manual switch or interlock kit does it by hand. All of them are installed by a licensed electrician under permit. Running a generator through a regular outlet is unsafe and not permitted anywhere in the U.S.
Can utility programs help pay for it?
Often, if you're in an outage-prone or high fire-risk area, or enrolled in a Medical Baseline program. Utilities in those regions offer backup power rebates — larger amounts for medically vulnerable and income-qualified customers — plus smaller rebates toward portable generators and battery power stations. Availability is tied closely to your utility and address.
Portable, standby, or battery — which makes sense?
A portable generator with a transfer switch is the lowest-cost path for essential circuits during shorter outages. A standby generator starts automatically and can run the whole house for extended outages, at the highest install cost and with fuel and maintenance. A home battery covers shorter outages silently with no fuel or exhaust and carries incentives a generator doesn't, but has limited runtime unless paired with solar. GridAssociation can help weigh them against the programs available where you live.
