What a 100A to 200A Panel Upgrade Really Costs in Calgary (2026)

If your Calgary home still runs on a 100-amp electrical service, you have probably already bumped into its limits — a tripped breaker when the dryer and the kettle run together, an electrician shaking their head at your hot tub plans, or an EV charger quote that came with an asterisk. Upgrading to a 200-amp service is one of the most common projects we are asked about, and the first question is almost always the same: what does it actually cost?

Here is an honest, no-asterisk overview of what a 100A to 200A panel upgrade involves in Calgary in 2026, what drives the price, and how to avoid the surprises that turn a clean quote into a messy invoice.

The short answer on price

For a typical residential overhead service upgrade from 100A to 200A in Calgary, you should budget roughly $4,000 to $6,000 all-in. That range reflects the local market — it covers the new panel, the meter base and mast, the service conductors, labour, the electrical permit, and the coordination with the City and the utility. Underground services, where the supply comes in below grade rather than from an overhead drop, generally cost more because of the additional trenching, conduit, and utility coordination involved.

Those are typical Calgary market ranges, not a fixed quote. Every home is different, and the only way to get a real number is a site visit.

What actually drives the cost

The spread between $4,000 and $6,000 (and beyond) is not arbitrary. A handful of factors move the needle:

• Overhead vs. underground service — underground almost always costs more.
• Where your panel lives — a tight mechanical room or a finished basement adds labour.
• Condition of existing wiring — knob-and-tube or aluminum branch circuits can trigger extra remediation.
• Mast and meter relocation — moving the service entrance is a bigger job than swapping the panel.
• Utility coordination — a service disconnect/reconnect with the local distribution utility has to be scheduled.

The permit: $116.50 and worth every cent

A panel and service upgrade is not DIY territory in Calgary. A City of Calgary electrical permit is required, and a licensed contractor will pull it as part of the job. For homeowners doing eligible work themselves, the City homeowner electrical permit is $116.50 — but a service upgrade involving the meter and utility supply is work a licensed electrician should be doing, and the permit is what triggers the independent inspection that protects you.

“The permit is not red tape — it is the receipt that proves a qualified inspector confirmed your service is safe. That paper matters at resale and at insurance-renewal time.”

Why people upgrade in the first place

A 200-amp service is quickly becoming the practical baseline for a modern Calgary home. The loads we plug into our houses keep growing, and 100 amps simply was not designed for them. The most common reasons we see:

• EV charging — a Level 2 charger is a substantial continuous load.
• Secondary suites — a legal basement suite often needs its own circuits and sometimes a sub-panel.
• Hot tubs — a dedicated 240V circuit and GFCI protection.
• Air conditioning — increasingly common as Calgary summers warm up.
• Modern kitchens, heat pumps, and shops — induction ranges, electric heat, and welders all add up.

How long does it take?

Most straightforward residential upgrades are completed in a single day, though you should plan for a power interruption while the work is done and the inspection scheduled. Coordinating the utility disconnect and reconnect is usually what stretches the calendar, not the electrical work itself, so booking ahead helps.

Questions worth asking any contractor

• Is the permit included in the quote, and who pulls it?
• Is this an overhead or underground service, and is that reflected in the price?
• Are there any wiring conditions in my home that could add cost?
• How will the power outage and inspection be scheduled?

A panel upgrade is one of those projects where a clear, permitted, properly inspected job is worth more than the cheapest number on the page — because you only want to do it once. A growing share of upgrades are also driven by a whole-home smart system rather than any single appliance — load-monitoring smart panels, automated switches and EV charging working together, which we cover in our guide to smart home wiring in Calgary.
