Richmond Hill electrical panel upgrades come in two sizes. Some are a panel swap behind the meter: a new breaker panel with more spaces, on the same service, to replace an obsolete or full one. Others raise the service itself, usually to 200 amps, and that version brings Alectra Utilities into the project because the supply has to be disconnected, inspected and reconnected.
Knowing which one you need decides the timeline. A swap is mostly a matter of the electrician's schedule and an ESA notification. A service increase adds an Alectra request, a review period and a coordinated disconnect date. The sections below walk through both, including what tends to drive the change in Richmond Hill homes and what the work costs.
What Richmond Hill Homeowners Should Know
Once a service in Alectra's territory has been upgraded, Alectra will reconnect it only after it receives a connection authorization from ESA. Alectra also gives residential customers one free planned disconnect every 12 months, though other charges tied to the upgrade may still apply (as of October 2026).

Requests under 200 amps are usually reviewed and booked in 5 to 10 business days, while upgrades to 200 amps or more typically need a service design with about four weeks of lead time (as of October 2026).

Panel Swap or 200 Amp Service Upgrade in Richmond Hill?
Electrical panel replacement in Richmond Hill, on its own, keeps the existing service rating. It makes sense when the panel is out of spaces, uses a model that insurers or inspectors flag, or shows heat damage, while the house still has enough capacity overall. The utility may still need to cut the power at the meter for the swap, and Alectra's application types include panel changes in the 60 to 100 amp range for exactly that reason.
A 200 amp service upgrade in Richmond Hill is the larger job. It replaces the main breaker and usually the service entrance cable, the meter base and, on an overhead supply, the mast, so the house can carry more load at once. Alectra classifies anything above 100 amps as a service upgrade, and for upgrades to 200 amps or more it typically prepares a service design, with roughly four weeks of lead time (as of October 2026). Smaller upgrades are usually reviewed and booked in 5 to 10 business days.
A load calculation settles which category a house falls into. It totals the existing appliances and heating with whatever is being added and compares the result with the rating on the main breaker.
Mast, Meter Base and Reconnection
On a house fed by overhead wires, Alectra treats everything from the top of the service mast into the panel as the owner's equipment. That means a corroded meter base, a leaning mast or undersized entrance cable is replaced by your contractor as part of the upgrade, not by the utility. Alectra owns and handles the wires that come from its pole.
The day of the changeover follows a fixed order. Alectra disconnects the supply, the contractor installs the new equipment, and ESA inspects it. ESA explains that a passed service inspection lets it authorize the utility to energize the service, and that authorization stays valid for up to six months. Alectra reconnects only once it holds that authorization, so the house stays without power until both steps are done.
Alectra's one free planned disconnect per 12 months usually covers the changeover (as of October 2026). Other costs linked to the upgrade can still apply, which is why the Alectra review matters before the date is fixed.
Second Units, New Loads and Upgrade Cost
Much of the pressure on older Richmond Hill panels comes from additions. Since By-law 143-24 allowed additional residential units in more zones, a second kitchen, laundry and heating system have become common requests, and the City notes that such a unit needs a separate ESA electrical permit on top of the building permit. A Level 2 car charger, a heat pump or a finished basement adds load in the same way, and the City's own guidelines send homeowners to ESA for the electrical notification.
As for the electrical panel upgrade cost in Richmond Hill, KV Bear Electrical's published range for a typical 100 to 200 amp panel upgrade is $2,500 to $5,000 (as of October 2026). The spread depends on whether the meter base, mast and entrance cable need replacing, how far the panel has to move, and how much existing wiring needs repair before it can be reconnected. Any Alectra charges are separate from that range and depend on its review.
Ask for a written, itemized quote that separates the panel, the service entrance work, the ESA fees and any patching, so two quotes can be compared on the same scope.
Panel Upgrade in Richmond Hill: Common Questions
How far ahead should I book a 200 amp upgrade in Richmond Hill?
Allow for Alectra's review before anything else. As of October 2026, upgrades to 200 amps or more typically need a service design with about four weeks of lead time, while smaller upgrades are usually booked within 5 to 10 business days. Starting the request as soon as the load calculation is done keeps the rest of a renovation from waiting.
Who replaces a damaged service mast on a Richmond Hill house?
The owner, through a Licensed Electrical Contractor. Alectra says that for an overhead service the owner is responsible from the top of the mast into the panel. Alectra handles its own wires and reconnects after ESA authorizes the repaired installation.
Will my power be off for long during a Richmond Hill service change?
The outage lasts from Alectra's disconnect until the new installation passes ESA's inspection and Alectra reconnects. Planning the inspection booking ahead of the disconnect date keeps that window as short as possible. Your contractor can explain the expected sequence for your house when the quote is written.
Does an additional residential unit in Richmond Hill always need a bigger panel?
Not always, but it should be checked. A second unit adds cooking, laundry and heating load, and the City requires a separate ESA permit for the electrical work. A load calculation on the existing service shows whether the current panel can carry both units or whether an upgrade has to come first. To book one, call 905-999-5048.
