Generator Cost
A standby generator must be mounted on a stable, level base — either a poured concrete pad or a pre-formed composite equipment pad. Pad cost is typically a modest line item within the overall installation budget, but it varies based on material choice, pad size, and local labor rates for site prep and concrete work.
Composite equipment pad
$150–$400
Estimated range. Actual cost depends on equipment, site conditions, and local labor rates.
Poured concrete pad
$300–$900
Estimated range. Actual cost depends on equipment, site conditions, and local labor rates.
Composite pads are faster to install and slightly less expensive; poured concrete requires curing time but is the most widely accepted option by local code. Site prep (grading, forming) adds to the total for either option.
