Electrical Panel & Service Upgrades in Calgary

A typical overhead 100A-to-200A upgrade in Calgary runs roughly $4,000–$6,000 all-in — the new panel, meter base, mast, conductors, labour, City permit and inspection. Underground services usually cost more due to trenching. Replacing a panel on an existing 200A service is generally $2,500–$4,000. Every home differs, so we quote after an on-site load assessment.

Yes. A panel or service upgrade requires a City of Calgary electrical permit, which triggers an independent inspection. Because the work involves the meter and utility supply, it is not homeowner-permit territory — a licensed contractor pulls the permit under their qualification and coordinates the ENMAX disconnect. Shock Stop handles the permit and inspection as part of every upgrade.

Most straightforward residential upgrades are completed in a single day, though you should plan for a temporary power interruption while the service is swapped and reconnected. The part that usually stretches the calendar is coordinating the ENMAX disconnect and reconnect and scheduling the City inspection — not the electrical work itself — so booking ahead helps.

It depends on your loads. A 100-amp service handles a basic home, but EV chargers, secondary suites, hot tubs, air conditioning and electric heat add up fast and can push it past a safe limit. A load calculation gives the definitive answer. In practice, 200-amp service has become the practical baseline for a modern Calgary home.

No. A service or panel upgrade involves the meter and the utility supply, which is work a licensed electrician must perform in Alberta — it is outside the scope of a homeowner permit. The high-current service connection, the ENMAX coordination and the mandatory City inspection are exactly why this job belongs with a licensed contractor, not a DIY project.

Often, yes. Federal Pioneer Stab-Lok breakers have a documented tendency not to trip when they should, and many Alberta insurers now flag them or refuse coverage until they are replaced. If you are upgrading anyway, replacing the panel with a modern 200-amp service closes the insurance issue and adds capacity. We can confirm the panel type on-site in minutes.

A panel upgrade swaps the breaker panel itself — useful when the service is already 200 amps but the panel is old, full or a Federal Pioneer. A service upgrade is bigger: it increases the actual amperage from the utility, replacing the meter base, mast and conductors too. Going from 100A to 200A is a full service upgrade.

Often yes. Many acreages around Rocky View County, Cochrane and the Foothills run original 100-amp services feeding a house plus outbuildings, shops or wells. Upgrades there frequently involve sub-panels, longer underground runs and higher loads. We handle acreage service upgrades and custom panel builds regularly — with the same permit, load calc and inspection process as in the city.
