100-amp to 200-amp electrical panel upgrades in Salt Lake City
Raising a 100-amp service to 200 amps is one of the most common panel conversations in Salt Lake City. It is a frequent upgrade path, not a rule that every 100-amp house must follow.
When 100 amps may still be enough
A 100-amp service is common on mid-century and later houses, including many in Sugar House. If the load calculation shows room for what you already use and what you plan to add, the honest answer may be to keep the existing service, add a circuit, or use a subpanel. That is a different job from a service upgrade.
When a 200-amp upgrade usually enters the conversation
- A Level 2 EV charger sized as a continuous load on a 60-amp breaker.
- A heat pump, especially if electric backup heat is part of the system.
- A kitchen or addition that needs several new circuits on an already tight panel.
- A sale, inspection, or insurance review that also flags outdated equipment.
What the job typically includes
A 100-to-200-amp upgrade is usually a permitted service change: a new 200-amp panel and main breaker, and often work on the meter base, mast, or grounding if the existing equipment cannot stay. Rocky Mountain Power personnel handle a physical meter disconnect. A city inspection typically has to pass before the utility reconnects service. The day-of guide and the permits guide walk through that sequence.
Read published cost figures as bands, not bids, on the cost page. If your service is older than 100 amps, see the 60-amp service guide. All related pages are on the guides hub.
Frequently asked questions
Does every 100-amp house in Salt Lake City need a 200-amp upgrade?
No. A 100-amp service can be enough for a typical house, or it can be tight if you add a heat pump, a Level 2 charger, or a major remodel. Only a load calculation on your house can say. Empty breaker spaces are not spare capacity.
How much does a 100-to-200-amp upgrade cost?
Osborne Electric’s 2026 Utah guide lists $1,800–$3,500 for a 100-amp to 200-amp upgrade. Utah Home Electric has published a typical Salt Lake City panel-upgrade range of $2,000–$4,000, and notes that meter-base or mast work can be higher. Those are published ranges, not a quote for your house.
Will the power be off?
Usually, yes, during a service change that requires a meter disconnect. Rocky Mountain Power personnel perform that disconnect. The utility does not, in the documents reviewed for this site, publish a guaranteed outage length. Your electrician should explain the likely window after the disconnect is scheduled.
Is 200 amps required by the city?
Salt Lake City requires a permit to install or alter an electrical system. It does not, on the official pages cited here, require every residence to be 200 amps. The new amperage is part of the written scope, based on the load calculation and the work you are doing.
