Natural gas generators cost less to install if a gas line exists, while propane requires a tank ($500–$2,000) and LP requires a dedicated supply.

If no gas line exists near the generator pad, running a new line can add $500–$2,000 depending on distance from the meter.
Most generators require a level concrete pad — existing flat surfaces save $300–$500 versus pouring a new pad.
