What size electrical panel do I need in Alberta? This is a common question many homeowners ask. Whether upgrading an older home or building a new one, it’s essential to know the right panel size to meet your power needs.
Choosing the correct electrical panel for your Alberta home is especially important when planning renovations or installing new systems like solar panels, an electric vehicle charger, or a hot tub.
The size of your electrical panel affects how much power your home can handle, ensuring both safety and efficiency.
In this guide, we’ll explore key factors to help you determine the appropriate panel size, discuss the advantages of upgrading, and cover details of electrical panel replacement in Calgary.
Why is Electrical Panel Size Important?
Your electrical panel is the central hub for distributing electricity throughout your home. It controls how much power flows to outlets, lights, appliances, and other systems. If your panel is too small for your home’s energy needs, it could lead to power shortages, tripped breakers, or, in worst-case scenarios, electrical fires. Upgrading to a properly sized panel ensures your home can safely handle modern energy demands.
Common Electrical Panel Sizes in Alberta

In Alberta, residential electrical panels typically range between 100 to 200 amps. A 100-amp panel is the minimum requirement for most homes, while a 200-amp panel is ideal for those with higher energy needs.
When building a new home in Calgary, consider an electric panel size that can accommodate your future needs. You’ll want to plan for high-demand systems like a Tesla Wall Connector or solar panels.
Electric Panel Size for New Homes in Calgary
New homes in Calgary often come with a 200-amp panel as standard, which is generally sufficient for modern energy demands.
This size allows you to run multiple appliances simultaneously without overloading the system. However, if you have a large home or plan to install an electric vehicle charger, a hot tub, or other high-consumption systems, you might need a larger panel.
According to the Canadian Electrical Code (CEC) Section 8, the minimum service size for new residential installations is 100 amps, but many builders opt for 200-amp panels to meet future needs and ensure compliance with energy demands.
When Should You Upgrade Your Electrical Panel?
If your home has an older electrical system, it’s likely running on a 60 or 100-amp panel. While this may have been sufficient in the past, today’s homes require significantly more power.
Appliances like refrigerators, washers, dryers, air conditioning units, and new technologies such as solar systems or electric vehicle chargers demand more electricity than older panels can provide.
A home electrical panel upgrade becomes necessary if:
- Your current panel is outdated (60-amp or 100-amp panel).
- You frequently trip circuit breakers.
- You’re planning major renovations or installing high-energy systems.
- You’re experiencing flickering lights or inconsistent power.
Upgrading to a 200-amp panel is often recommended for homes that use more than 100 amps of electricity.
To ensure your upgrade meets safety standards, always consult a licensed electrical contractor in Alberta.
That said, how much does it cost to upgrade to a 200-amp panel in Alberta?
Cost to Upgrade to a 200-Amp Panel in Alberta

The cost of an electrical panel upgrade varies depending on the complexity of the installation and your location.
Across Alberta, the cost to upgrade to a 200-amp panel typically ranges from $2,500 to $4,500. Contact a local panel upgrade service company for an exact estimate.
Factors that can influence the cost include:
- Whether the upgrade requires service from your local utility provider.
- The condition of your existing wiring.
- The need for additional sub-panels.
- Labor costs for electricians in your area.
It’s always a good idea to get multiple quotes from a reputable electrical panel upgrade company in Calgary to ensure you’re getting the best service for a fair price.
Panel Upgrade vs. Service Upgrade
When upgrading your electrical panel, you may come across the term “service upgrade.”
While a panel upgrade refers to replacing your existing panel with a larger one, a service upgrade involves increasing the capacity of your entire electrical system. This includes upgrading the utility supply line, the meter, and possibly the main breaker.
A service upgrade is necessary if your home requires more power than what’s currently supplied by your utility provider.
For example, upgrading from a 100-amp service to a 200-amp service requires your provider to increase the power delivered to your home.
In many cases, homeowners opt for both a panel and service upgrade at the same time to ensure their electrical system can handle future demands.
How to Choose the Right Electrical Panel

When deciding what size electrical panel you need, consider the following factors:
- Current Electrical Usage – Take inventory of the electrical appliances, systems, and devices you use regularly. Homes with air conditioners, electric vehicle chargers, or high-end kitchen appliances often need a 200-amp panel.
- Future Plans – Are you planning on expanding your home, installing a hot tub, or converting your garage into a workshop? It’s wise to choose a panel size that can accommodate future upgrades.
- Local Codes and Regulations – Alberta has specific electrical codes that may require a certain panel size based on your home’s square footage and electrical usage. A licensed electrician can guide you through these requirements.
- Type of Service – Does your home have single-phase or three-phase power? Single-phase is common in most homes, but if you run large industrial equipment or operate a commercial space, three-phase power might be necessary.
Working with a qualified electrician is the best way to ensure you select the right electrical panel for your home.
