Natural gas generators typically range in size from around 8 kW to 150 kW or more, with larger generators capable of providing backup power to entire homes. Consulting with a professional electrician or generator dealer can help accurately determine the size of the natural gas generator needed to meet your household's power demands.

Can a whole house generator run on natural gas?
