100A to 200A Panel Upgrade Cost
The single most common residential panel upgrade. Plan-level installed cost with state labor multipliers, meter/main replacement, utility coordination, and the panel-replacement vs. service-upgrade cost split.
Quick answer: $2,000–$4,500 typical, $4,500–$7,500 in high-cost markets (CA, HI, NYC). A smart load-management device ($500–$1,500) is often a cheaper alternative — see below.

Frequently asked questions
How much does a 100A to 200A panel upgrade cost?
A typical 100A→200A upgrade is $2,000–$4,500 installed nationally, with high-cost markets (California, Hawaii, NYC metro) running $4,500–$7,500. The work usually includes a new 200A main breaker, a new meter base, replacement of the service-entrance conductors, grounding/bonding to current code, and a utility coordination visit.
Is a 200A panel always necessary for an all-electric home?
No. NEC 220.83 load calculations frequently show a 100A panel can handle a heat pump + EV charger + induction range if existing loads are modest. A smart load-management device ($500–$1,500) often replaces a $4,000 upgrade by scheduling large loads so the home never exceeds the existing service capacity. Always have a licensed electrician run the load calc before committing.
What is the federal tax credit on a panel upgrade in 2026?
The federal 25C credit covered panels up to $600 (30% of cost) when paired with a qualified energy efficiency improvement, but OBBBA (signed July 4, 2025) terminated 25C for property placed in service after December 31, 2025. For installs in 2026 or later, no federal credit applies. State and utility rebates may still apply — see /rebates/.

How long does the work take, and how long is power off?
A typical 100A→200A service upgrade is a one-day job, but power is off for 4–8 hours during the cutover. If the utility has to replace the service drop or relocate the meter, the calendar can stretch to 2–3 weeks even though on-site work is still a day or two. The utility part is usually free; the electrician's part is the cost.
