UPDATED: April 2026 One of the most common concerns homeowners have when exploring a heat pump, EV charger, or other electrification upgrade is whether their home's electrical panel can handle the additional demand. For years, the answer often involved an expensive panel upgrade. In some cases, homeowners were told they couldn't move forward with certain projects without upgrading their electrical service altogether. Today, that conversation is changing! Thanks to updates in Ontario's Electrical Safety Code and advances in energy management technology, many homeowners now have another option: load managers. These smart devices can help maximize the capacity of your existing electrical system and, in many cases, make electrification projects possible without the need for costly panel upgrades. Why Electrical Capacity Matters As more homeowners transition away from fossil fuel-powered equipment, homes are using electricity in new ways. Heat pumps, electric vehicle chargers, heat pump water heaters, and other efficient technologies all require electrical capacity. The challenge is that many Ontario homes were built decades ago, long before these technologies became common. As a result, some homeowners discover that their electrical panel appears too small to support additional equipment. Traditionally, this often meant upgrading to a larger electrical panel, which can add significant cost and complexity to a project. What Is a Load Manager? A load manager is a type of Energy Management System (EMS) that helps your home use electricity more intelligently. Think of it as a traffic controller for your home's electrical system! Rather than allowing all appliances to operate at full demand simultaneously, a load manager continuously monitors electricity usage and temporarily pauses selected non-essential loads when necessary. Once demand drops, power is automatically restored. The process happens in the background without requiring homeowner intervention. How Load Managers Work Every home has certain appliances that don't necessarily need to run at the exact same moment. Examples may include: EV chargers Electric dryers Electric stoves Battery charging systems Other discretionary electrical loads A load manager monitors overall demand and automatically adjusts these loads when required to keep your home operating safely within its electrical capacity. The result is a more efficient use of your existing electrical infrastructure! What Changed in Ontario's Electrical Safety Code? One of the most significant developments came with updates to the Ontario Electrical Safety Code. The updated code expanded the recognition of Energy Management Systems beyond electric vehicle charging applications. This means approved energy management technologies can now be used to manage a wider range of electrical loads while maintaining compliance with electrical safety requirements. For homeowners, this creates new opportunities to pursue electrification projects that may previously have required major electrical upgrades. Why This Matters for Heat Pumps Heat pumps are one of the most popular home electrification upgrades available today. They provide both heating and cooling while helping homeowners improve efficiency and reduce reliance on fossil fuel-based heating systems. However, many homeowners have been told that installing a heat pump requires a larger electrical panel. While every home is different, load managers can sometimes provide an alternative solution. By intelligently managing electrical demand, they may help create the capacity needed for a heat pump installation without requiring a full panel upgrade. This can make electrification more accessible and affordable for many households! A Real-World Example Here at1Click Energy Solutions, we've already seen the impact of load management technology firsthand. One example involved a project at Winthrop Court in Ottawa, where 64 housing units were being upgraded with heat pumps. Initial load calculations suggested there wasn't enough available electrical capacity to support the installations. Even upgrading individual panels would not have solved the challenge because the incoming electrical service remained limited. By implementing load managers and working closely with regulatory authorities, the project was able to move forward successfully. The result was a practical electrification solution that avoided costly infrastructure upgrades while maintaining safety and compliance. Pretty awesome, right? The Benefits of Load Managers For homeowners considering electrification projects, load managers can offer several advantages. 1. Potential Cost Savings A load manager is often significantly less expensive than a full panel upgrade or electrical service upgrade. 2. Expanded Electrification Opportunities Projects that may have seemed impossible due to electrical limitations could become feasible. 3. Faster Project Timelines Avoiding major electrical upgrades can simplify installation and reduce disruption. 4. Improved Use of Existing Infrastructure Load managers help homeowners get more value from their current electrical system. 5. Support for Future Energy Upgrades As homes continue to evolve, load managers can help support future additions such as EV chargers, heat pumps, and other energy-efficient technologies. Is a Load Manager Right for Every Home? Not necessarily. Every home's electrical system is unique, and the best solution depends on factors such as: Existing panel size Electrical service capacity Planned equipment upgrades Current energy usage Future electrification goals A professional assessment is the best way to determine whether a load manager, panel upgrade, or another solution makes the most sense for your home. Looking Ahead As more Canadians adopt heat pumps, electric vehicle chargers, and other energy-efficient technologies, finding smart ways to manage electrical demand will become increasingly important. Load managers are helping remove one of the biggest barriers to home electrification by making better use of existing electrical infrastructure. For many homeowners, that means greater flexibility, lower costs, and more opportunities to invest in a comfortable, efficient, and future-ready home. At 1Click Energy Solutions, we help homeowners explore practical electrification solutions that fit their home's unique needs. Whether you're considering a heat pump, EV charger, or other energy-efficient upgrade, understanding your electrical options is an important first step.
