What Size Standby Generator Does My Albany Home Need?
If you’ve started looking into backup power, you’ve probably asked yourself:
“What size generator do I really need for my house?”
It’s one of the most common questions we hear from homeowners in Albany, Delmar, and across the Capital Region. Choosing the right size standby generator is critical — too small, and you’ll overload the unit; too large, and you’ll overspend unnecessarily. Far too many contractors will look at a house and say, “you need “___X___” size generator. This is a horrible practice the culprit for many of the service calls we take. From a practical aspect as well as for National Electric Code compliance, the generator needs to be sized to the appropriate electric load of the house and what the generator is wired in to power. Two houses can look exactly the same from the outside and have the same square footage, but have vastly different electrical load requirements due to the appliances inside; air conditioners, heat pumps appliances, mini splits, clothes dryers, stoves/ovens, fish/animal habitats, etc.
How Generator Sizing Works
Standby generators are rated in kilowatts (kW), which measure how much electricity they can produce. The size you need depends on the electrical load of your home.
- Essential Circuits Only (10–14 kW): Covers some lights, heat, refrigerator, sump pump, furnace, and a few outlets.
- Most of the Home (18–22 kW): Powers essentials plus well pump, garage doors, central AC, and kitchen appliances. This is the most common size range for homes in Albany County.
- Whole-Home Coverage (24–28 kW+): Powers everything, including multiple HVAC systems, electric ranges, hot tubs, EV chargers or larger homes over 3,000 sq. ft.
Factors That Determine Your Generator Size
- Home Square Footage
Larger homes typically need larger systems — but square footage alone isn’t enough. - Appliances & Heating Systems
Electric stoves, central AC, grinder pumps and well pumps all add significant load. - Lifestyle Needs
Some families only want basics like heat and refrigeration, while others want seamless whole-home coverage. - Future Growth
Planning a home addition or finishing a basement, pool or hot tub, EV charger? It may be worth sizing up now.
