| Delivery/Disposal | $200 | $600 | $1,000 | Site access and packaging removal |
What Drives Price
Power rating and fuel choice are primary drivers, with 22 kW units balancing capability for whole-home load and AC usage. Installation complexity and local permitting add material and labor costs, particularly if existing wiring or trenching is required.
Other drivers include transfer switch size (amps), indoor vs outdoor enclosure, and gas supply requirements. Higher efficiency engines or dual-fuel configurations raise upfront costs but may lower operating expenses long-term. Labor hours × hourly_rate data-formula=”labor_hours × hourly_rate”>
Regional Price Differences
Prices vary by region due to labor markets and permitting. In the Northeast, expect higher installation costs due to tougher codes, while the South may see lower labor fees. The Midwest often falls in between. A regional delta of approximately ±15% to ±25% is common when comparing urban, suburban, and rural pricing.
Regional example ranges include a typical: Urban: $9,000-$16,000, Suburban: $8,000-$14,000, Rural: $7,500-$12,000. Assumptions: standard 22 kW setup, asphalt or concrete pad, standard electrician crew.
Real-World Pricing Examples
Basic scenario — 22 kW propane, outdoor enclosure, minimal trenching, 4-6 hours of labor, standard 100-amp transfer switch. Assumes: suburban site, standard permit process.
Specs: 22 kW propane generator, 100 A ATS, basic weather cover
Labor: 6 hours @ $120/hour → $720
Parts & Materials: $5,000
Total: $6,520
Monthly maintenance: $15–$25
Assumptions: region, specs, labor hours.
Mid-Range scenario — 22 kW natural gas, enclosed installation, trenching for a short run, 8–12 hours of labor, 200 A ATS. Assumes: updated home with existing gas line.
Specs: 22 kW NG generator, 200 A ATS, steel enclosure
Labor: 10 hours @ $150/hour → $1,500
Parts & Materials: $7,000
Delivery/Prep: $500
Total: $9,000
Premium scenario — 22 kW dual-fuel, reinforced pad, full trenching, 15–20 hours of skilled labor, high-end enclosure, extended warranty. Assumes: complex install, urban center.
Specs: 22 kW dual-fuel generator, 200 A ATS, premium enclosure
Labor: 18 hours @ $180/hour → $3,240
Parts & Materials: $9,500
Permits/Inspections: $1,000

Maintenance & Ownership Costs
Annual maintenance typically ranges $150-$350 for routine service, including fuel system checks and battery tests. Over a five-year period, ownership costs can exceed initial price if parts replacement or warranty extensions are needed. Assumptions: standard service intervals, average fuel prices.
Price By Region
Regional variations are common, with higher install costs in crowded markets (e.g., coastal cities) and lower rates in rural areas. A practical planning rule is to budget a ±20% window around the national average, adjusting for permit complexity and accessibility.
