The demand for Energy Storage Systems (ESS) is rising in Ontario, driven by homeowners and businesses seeking cost-saving opportunities, improved energy reliability, and increased energy needs.
As Ontario focuses more on clean energy initiatives, the demand for skilled Licensed Electrical Contractors (LECs) to facilitate the integration of ESS—often alongside solar and EV infrastructure—is expanding rapidly. This growing interest is evident across the province, from rural and cottage country communities to urban and commercial centres.
The shift towards sustainability and the need for timely availability of electricity are creating new opportunities for LECs to collaborate with municipalities and businesses aiming to implement energy-efficient solutions. By integrating ESS, LECs help these organizations harness the full benefits of energy storage—shifting electricity availability to peak times, supporting daily energy demands, and helping to mitigate power outages and supply disruptions. Energy storage also enables better integration of renewable sources, such as solar and wind, which introduce variability to the grid.
Home and On-Site Battery Storage
At the residential and small commercial level, battery storage systems provide backup power during outages, help lower peak demand costs, and store solar or grid energy for later use. These systems can power essential devices and appliances day or night, offering flexibility during outages or off-grid operation.
Utility-Scale Energy Storage
Utilities are also investing in large-scale energy storage, as it offers a flexible and cost-effective alternative to traditional infrastructure upgrades, such as new pole lines or transformers, which helps to defer major capital expenditures. Additionally, ESS enables them to manage peak demand and improve grid reliability, serving consumers better.
This broad adoption across residential, commercial, municipal, and utility sectors underscores the expanding role of ESS in Ontario’s energy landscape.
Safety and Compliance: Why LECs Are Essential for ESS Installations
Ensuring the safety and regulatory compliance of energy storage system installations is critical, making the expertise of licensed electrical contractors indispensable.
The increasing popularity of ESS has unfortunately led to the emergence of non-certified equipment in the market, underscoring the need for buyers and installers to verify the correct certification marks. For an ESS to be considered safe and compliant, the entire system must be approved to UL 9540. Furthermore, in multi-part Battery Energy Storage Systems (BESS), individual components also require specific certifications: batteries must be approved to UL 1973, and inverters to UL 107.1.
For these reasons, DIY installations pose significant safety risks, potentially leading to electrical hazards. Trevor Tremblay, Technical Advisor for the Electrical Safety Authority (ESA), explicitly warns against DIY installations. He shares that “These are very complex installations” and states that such attempts might result in useless and expensive equipment, and at worst, could lead to devastating consequences, such as a fire.
Licensed electrical contractors in Ontario possess the knowledge to ensure all components meet the established standards. They are also trained to adhere to specific installation guidelines, including the use of voltage-rated, fine-strand cables and maintaining at least one meter of clear space.
Optimizing ESS Performance: Integration with EVs and Other Systems
The growing integration with Electric Vehicle (EV) chargers is a notable energy storage system trend. Trevor Tremblay explains that Ontario now sees ESS inverters emerging with EV charger systems built directly in. “You plug the car right into the ESS,” he says. This convergence of technologies highlights the expanding role of ESS beyond basic backup power and towards a more holistic home energy management system.
Similarly, pairing ESS with solar energy systems maximizes energy independence, especially in remote locations. This allows users to primarily rely on solar power and stored energy, significantly reducing electricity costs through strategic energy management.
Ontario’s licensed electrical contractors optimize the performance and efficiency of these integrated systems by balancing energy storage capacity, usage patterns, and load management. They are qualified to design and implement systems that intelligently manage energy flow between solar panels, ESS, EVs, and the grid. Choosing licensed electrical contractors with specialized certifications, like EVITP, ensures the safe, compliant, and efficient integration of these evolving technologies, allowing homeowners and businesses to realize the full potential of their energy management system.
