Shopping for a standby generator starts with one question: what's this actually going to cost me? The honest answer is that the generator unit is only about 40% of the total — the transfer switch, gas hookup, electrical work, permits, and labor make up the rest. Two homes buying the "same" 22kW Generac can see quotes thousands apart depending on gas line length, panel condition, and placement.
That's exactly why every Generac installation we do starts with a free on-site assessment and a written quote. But if you want real numbers before you call anyone, this guide lays out typical Baltimore County pricing for 2026.
Typical 2026 ranges for Baltimore County. "Installed" includes the automatic transfer switch, gas hookup, pad, permits, and labor.
| Generator size | Best for | Unit only | Installed, all-in |
|---|---|---|---|
| 10–14 kW Essential circuits | $2,800–$4,500 | $9,000–$11,500 | |
| 18 kW Larger essentials / small whole-home | $4,000–$5,200 | $10,500–$13,000 | |
| 22–24 kW Whole-home (most popular) | $4,800–$6,000 | $11,500–$14,500 | |
| 26 kW Large whole-home | $5,500–$6,800 | $13,000–$15,500 |
Liquid-cooled Generac Protector units (30kW+, for estates and large homes) typically run $16,000+ installed. Your exact number comes from the free assessment — get yours here.
Six factors explain nearly all the variation between quotes:
The unit itself is the biggest line item. A 26kW costs roughly twice what a 14kW does — but oversizing wastes money, which is why the free load calculation matters.
Whole-home automatic transfer switches cost more than essential-circuit (managed) panels. Most Baltimore County installs use a 200-amp service-rated switch.
If your meter is far from the generator pad, trenching and piping add cost. Homes without natural gas need a propane tank install instead.
Older panels (common in Catonsville, Dundalk, and Overlea) sometimes need upgrades to accept the transfer switch safely.
Baltimore County requires electrical and fuel-gas permits. We pull them and schedule inspections as part of every install.
A level concrete pad, code clearances from windows/doors, and snow/landscaping considerations — straightforward on most suburban lots.
Most whole-home Generac installations in Baltimore County run $9,000–$15,000 all-in, including the unit, automatic transfer switch, gas hookup, permits, and labor. Smaller essential-circuit setups start around $9,000; large 26kW whole-home systems reach about $15,500.
Roughly 40% of the total is the generator unit and 60% is installation — transfer switch, gas line, electrical work, pad, permits, and labor. That's why two quotes for the 'same' generator can differ by thousands: the install scope is what varies.
The 22–24kW range is the sweet spot for most homes here — enough for whole-home coverage including HVAC. Homes under ~2,000 sq ft with gas heat often do fine at 14–18kW. We confirm with a free load calculation rather than guessing.
If BGE outages cost you spoiled food, hotel nights, lost work-from-home days, or a flooded basement from a dead sump pump, a standby generator typically pays for itself in avoided losses and peace of mind within a few storm seasons. It also shows up favorably in resale listings.
