"Kyle, the owner of Canyon Electric, was recommended to us as a trustworthy electrician in the Black Hills area. We had purchased a vacation home in Lead and were having a hot tub and sauna installed. We needed to add 2 240 amp breakers, a new breaker box, and hard wiring both units. We are from across the state and had a deadline for the hot tub installation, which required all wiring done very specifically and in place. Kyle was out at our home wiring and prepping before we even arrived. He was in contact with our hot tub retailer and made sure everything was done perfectly. The wiring on both units was done efficiently. He even did work on one of our bathroom exhaust fans and had it going in quick order. Kyle was a very pleasant person to deal with and we were very impressed with the high standards of his work. We would highly recommend Canyon Electric for any and all of your electrical needs."

Generator Install questions, answered by experts

Generators run on a variety of fuel types, ranging from natural gas to solar power. Keep in mind that fuel costs varying by type:

  • Natural gas: $2,000–$21,000 per year 

  • Liquid propane: $2,000–$21,000 per year

  • Diesel: $3,000–$20,000 per year

  • Gasoline: $500–$3,000 per year

  • Solar generator: $2,000–$25,000 per unit

  • Battery backup: $10,000–$25,000 per unit

You may need a permit for a portable generator if you’ll be installing a transfer switch for your primary residence or similar work. Otherwise, a permit for other uses may not be necessary. Check your local building codes or ask a local generator installer for more information about your local regulations.

Setting up utilities on a vacant property usually takes at least a few months, or between 6 weeks to 16 weeks. This process requires working with the local planning and zoning department, hiring a building contractor or engineer to design the utility layout, securing permits, laying the lines, and connecting the utilities.

To reduce AC startup power for a whole-house generator, install a soft start kit or hard start capacitor, which lowers the initial surge by gradually ramping up the compressor. Using a smart load manager can also help by staggering startup loads, preventing a system overload and future costly repairs.

Costs range from $500 to $2,500, depending on generator type and installation complexity.
