Electrical Panels & Smart Panels
A heat pump, induction range, EV charger and heat pump water heater all need capacity in the electrical panel. Before you buy any of them, the useful question is whether the existing service can carry the new loads, and if not, whether a panel upgrade, a smart panel or load management is the cheaper path.

The Panel Decides What You Can Electrify
A heat pump, induction range, EV charger and heat pump water heater all need capacity in the electrical panel. Before you buy any of them, the useful question is whether the existing service can carry the new loads, and if not, whether a panel upgrade, a smart panel or load management is the cheaper path.
Upgrade, Subpanel or Smart Panel
A full service upgrade adds capacity but often involves the utility, a permit and new service wiring. A subpanel adds circuits, not capacity. A smart panel or a load-management device lets a smaller service run more appliances by switching loads off when demand peaks. Each has a different cost, timeline and rebate treatment.
Do the Load Math First
A load calculation based on the electrical code tells you how much capacity the house really uses. Many homes that look full on paper can add an induction range or a charger with load management instead of a new service. The guides below walk through the calculation, typical costs and what to ask an electrician.
Read the capacity guide first, then compare the upgrade cost and smart panel guides. Programs that pay for panel work are listed in the rebates by region section.
