Why 200 amp service upgrade comes up in Boulder
Boulder has some of the most ambitious electrification goals in the country, and replacing a gas furnace with a heat pump, adding a heat pump water heater, an induction range, an EV charger and rooftop solar often pushes a 100 amp service past its limit. A 200 amp upgrade usually includes a new meter base and service entrance coordinated with Xcel Energy; in some homes, a smart panel or load-management device avoids the upgrade. The city has offered electrification rebates that change over time.
Permits come from the City of Boulder's Planning and Development Services.
