Why 200 amp service upgrade comes up in Tacoma
Tacoma Power's low rates have made electric heat pumps, heat pump water heaters and EV chargers attractive, and older homes in the North End and Hilltop with 60 or 100 amp services often cannot carry them all. A 200 amp upgrade usually includes a new meter base and service mast coordinated with Tacoma Power. Smart panels or load management can sometimes avoid the upgrade.
Tacoma Power has offered conservation programs that change over time. Permits come from the city's Planning and Development Services. Ask for the load calculation in writing.
