Why 200 amp service upgrade comes up in Cheyenne
Cheyenne homeowners adding heat pumps, EV chargers, hot tubs or heated shops often find older homes in the Avenues and central neighborhoods have 60 or 100 amp services. A 200 amp upgrade usually includes a new meter base and service mast, and because wind and hail damage masts more often here than in most cities, the new mast should be sturdy and properly braced. Black Hills Energy schedules the disconnect and reconnect, and winter work is planned to keep the furnace off for as little time as possible.
Permits come from the City of Cheyenne.
- Many Cheyenne homes in the Avenues and the older central neighborhoods have small services, and mid-century houses often have 100 amp panels that cannot handle a heat pump, an EV charger, a hot tub or a heated shop.
- Older homes may have 100 amp services, so a load calculation decides whether a 40 or 48 amp charger fits.
- Permits in Cheyenne
- Electrical permits inside city limits come from the City of Cheyenne's building safety department; unincorporated Laramie County has its own process. Wyoming licenses electricians through the Department of Fire Prevention and Electrical Safety.

200 Amp Service Upgrade in Cheyenne: questions
Do I need a permit for 200 amp service upgrade in Cheyenne?
Usually, yes. Electrical permits inside city limits come from the City of Cheyenne's building safety department; unincorporated Laramie County has its own process. Wyoming licenses electricians through the Department of Fire Prevention and Electrical Safety. The electrician normally pulls the permit and schedules the inspection.
Is the utility involved in Cheyenne?
If the work affects the meter or service, the electrician coordinates with Black Hills Energy, which owns the meter and service drop.
Do I need 200 amps for an EV charger?
Not always. A load calculation may show that a 100 or 150 amp service can support a charger, especially with a lower charging setting or a load-management device.
How long does a 200 amp upgrade take?
The installation is often one day, but utility scheduling and permits can add days or weeks.
Does the utility charge for a service upgrade?
Some utilities charge fees or require their own work on the service drop. Policies vary, so ask your utility.
Is 400 amps ever needed?
For very large homes or homes with electric heat, pools and multiple EV chargers, a larger service may be justified by the load calculation.
