# Electrical Panel Upgrade in Potomac Mills, VA

A panel or service change in Potomac Mills needs a Prince William County electrical permit, and the shut-off is booked with Dominion Energy or NOVEC depending on which side of the territory line your home sits. Most homes here are from the 1980s and 1990s and about 73% heat with electricity, so many panels are already carrying a heavy load before anything new is added.

## Electrical Panel Upgrades in Potomac Mills: the facts

Permit for a panel or service

[Yes: the county fee schedule lists a new or replacement service as permit work for existing homes](https://www.pwcva.gov/assets/2021-04/12288.pdf)

Who issues it

[Prince William County Building Development Division, 703-792-6930, through the county ePortal](https://www.pwcva.gov/department/building-development-division)

Power company

[Most homes: Dominion Energy. Shopping core by the mall: NOVEC. Check your bill.](https://eedgis.pnnl.gov/arcgis/rest/services/Hosted/Electric_Service_Territories/FeatureServer/0)

Electric heat

## Why do Potomac Mills panels fill up so fast?

Heat is the big reason. The [Census profile](https://censusreporter.org/profiles/16000US5164152-potomac-mills-va/) shows about 73% of occupied homes here heat with electricity, and only 27% with utility gas. A heat pump with electric backup strips can take a large share of a panel's capacity on a cold morning.

Age is the other reason. The median home was built in 1988, and about 64% went up in the 1980s and 1990s. Panels from those years were sized for the house as it was then. Many now have every slot full, with tandem breakers squeezed in over the years.

So before we change anything, we read the panel label, count the spaces and do a load calculation. That tells us if a bigger panel, a larger service, or just some rearranging is the right fix. You can get a first estimate with our [panel load calculator](/tools/panel-load-calculator/).

## NOVEC or Dominion: how the shut-off works here

Potomac Mills is split between two power companies. On the federal [service territory map](https://eedgis.pnnl.gov/arcgis/rest/services/Hosted/Electric_Service_Territories/FeatureServer/0), about 68% of the land is Dominion Energy and 32% is NOVEC. The county's [subdivision map](https://gisweb.pwcva.gov/arcgis/rest/services/OpenData/OpenData/MapServer/3) places Rollingwood Village, Forest Vista and Woodmont on the Dominion side, while the mall and nearby centers are NOVEC.

If you have Dominion, the company cuts power for the swap and will not turn it back on until it sees proof of a passed inspection, per its [stop service page](https://www.dominionenergy.com/virginia/start-stop-service/stop-service). A move to a larger service takes a longer, scheduled disconnect.

If you have NOVEC, you call 703-392-1643, extension 1643, and NOVEC books a technician to disconnect. Reconnection is a second appointment with its System Operations team, per the [NOVEC service page](https://www.novec.com/service.cfm). Homes near Springwood and Prince William Commons sit close to the line, so we always ask to see the bill first.

## County permit and inspection steps

Potomac Mills is not a town, so the Prince William County [Building Development Division](https://www.pwcva.gov/department/building-development-division) issues the permit. A replacement service is a listed item on the county [fee schedule](https://www.pwcva.gov/assets/2021-04/12288.pdf). The permit card must be posted at the front of the house where it can be seen from the street.

Inspections are booked in the ePortal or by phone at 1-866-457-5280, and inspectors visit on weekdays from 8 a.m. to 3 p.m., per the county [EV charging page](https://pwcva.gov/department/building-development-division/residential-EV-charging-stations). We set the power company date after the inspection slot is known.

A new service also brings 2021 code items. The county's [code change page](https://www.pwcva.gov/department/building-development-division/vusbc) lists a surge protective device on dwelling services and an emergency disconnect for houses and townhomes. The county says the disconnect rule does not apply to exact replacements, so we tell you up front which items your job triggers.

## Electrical Panel Upgrades questions in Potomac Mills

What Potomac Mills homeowners ask about electrical panel upgrades.

![Zappy pointing to a breaker panel](/brand/zappy/zappy-electric-sandro-mascot-panel-upgrade-300.webp)

Do I need a permit to replace my electrical panel in Potomac Mills?

Yes. Prince William County treats a new or replacement service as permit work, and an inspector must pass it. If Dominion serves your home, it needs that passed inspection before it turns the power back on.

Is my Potomac Mills home on NOVEC or Dominion for a panel upgrade?

Most homes are Dominion Energy. The shopping core near the mall is NOVEC, and a few blocks sit near the line. The name on your electric bill decides which utility handles the shut-off.

My Potomac Mills house has a heat pump. Do I need a bigger panel for an EV charger?

Not always. Electric heat uses a lot of capacity, so we run a load calculation first. Sometimes the panel has room, and sometimes a larger service or a load management device is the better fix.

Does a panel upgrade in Potomac Mills need a surge protector now?

A new dwelling service under the 2021 code needs a surge protective device, per Prince William County. We include it in the plan when your job counts as a new service.
