The Home Electrification Order of Operations

Electrify in the wrong order and you’ll oversize some systems, undersize others, and pay twice for electrical work. The right order is mostly universal — and it starts smaller than people expect.

The sequence

• 1. Measure first. A home energy monitor (~$100–$300) shows where power actually goes — every later sizing decision improves. Cheap insulation and air-sealing wins hide here too.
• 2. Panel check. If big loads are coming, confirm your electrical panel has capacity now, and bundle any upgrade with the first project’s permit rather than paying for two site visits.
• 3. Replace what’s dying, electric. The cheapest time to electrify a furnace, water heater or stove is when the old one fails — the swap premium is small compared to a healthy-appliance replacement. This is where a heat pump usually enters.
• 4. EV charger when the EV arrives — a Level 2 install is a modest, contained project, and overnight rates start saving immediately.
• 5. Solar after loads are known. Size panels to your electrified consumption, not your old bill — solar sized before a heat pump and EV is solar undersized. See state costs.
• 6. Battery last, if your profile justifies one — by now you know your real usage curve and export rates.

The through-line: information → capacity → loads → generation → storage. Each step makes the next one cheaper to size correctly, and every calculator on this site maps to one step.
