Reliability & Resiliency

As Ontario’s seventh-largest electricity distributor, we take immense pride in overseeing and maintaining a vast network of overhead and underground powerlines – enough to travel from Waterloo to Whitehorse, Yukon and back again. Our commitment to excellence and stewardship of this critical infrastructure is second to none.

Reliability

83 minutes

average duration of power outages

The average power outage lasted 83 minutes for Enova customers, due in part to a significant winter storm in late December

46,000+

poles

Our crews maintain more than 3,500 km of overhead wire connected by 46,204 poles.

235

smart switching devices installed

We’ve installed more than 200 smart switching devices across our distribution system, including 10 new devices in 2025. These investments continue to strengthen system reliability and resiliency by helping reduce the frequency and duration of outages, while improving overall operational efficiency.

To ensure our communities always have the safe, reliable electricity they deserve, we proudly invest in system renewal, upgrades, and advanced technology. In 2025, we invested more than $56M in capital projects to strengthen the resiliency of our system and replace vital infrastructure. We boosted the number of automated devices in our system to 235. Automated devices help to detect faults and automatically switch to minimize the impact of outages where possible. This includes our Fault Location, Isolation, and Service Restoration software, which continues to help minimize the length, frequency, and severity of outages. Coupled with regular tree trimming and proactive vegetation management throughout our entire service territory, our customers can be assured of a safe, reliable supply of electricity.

On average, Enova customers experienced 1.3 outages in 2025. The average power outage lasted 83 minutes for Enova customers, due in part to a significant winter storm in late December that included freezing rain and high winds. Crews worked under difficult conditions during the storm to restore power to more than 46,000 customers impacted by outages caused by ice accumulation on electrical equipment, tree contact with overhead conductors and wind-related damage to our distribution system. Power was restored to 90% of customers within 24 hours, and to all impacted customers within four days.

Our crews stepped up to the challenge when an ice storm hit Ontario in March, 2025. We deployed teams of powerline technicians and utility arborists—along with tools, trucks, and equipment—to help InnPower, Lakeland Power, and Hydro One restore power to impacted customers.

Innovation

Driven by our “Growth and Innovation” strategic pillar, we continue to explore and execute innovative projects that will meet the ever-evolving needs of our communities and customers.

In 2025, we concluded a Distribution System Operator (DSO) lab-based demo at our Victoria Street office. The Electricity Distributors Association’s LDC Tomorrow Fund funded the demo, which tested the operation of a real-time DSO, including accepting bids from market participants and optimally scheduling Distributed Energy Resources DER without compromising grid reliability. The findings of the demo helped establish a practical framework for operating a demand-response non-wires program that utilities across the province could widely adopt.

We continued working with Ontario-based cleantech startup GridS2, on a project using GridS2’s cutting-edge AI-driven transactional energy platform. The outcome of this pilot project will support the utility’s transition toward operating a real-time DSO, including the ability to accept bids from market participants and optimizing the scheduling of DER assets while ensuring grid reliability.

The project was one of five clean energy projects to receive a portion of the $13 million in federal funding announced in August by Natural Resources Canada (NRCan) through the Energy Innovation Program – Smart Grid Demonstration. It directly supports NRCan’s strategic priorities to decarbonize energy systems, defer costly infrastructure upgrades, and enhance grid resilience.

We are testing the program on our own distribution system in areas with system constraints, and if successful, it could lead to expansion to other electrical utilities in Ontario.

Protecting Data

As cyber threats targeting critical infrastructure become more sophisticated, cybersecurity and the protection of our data remains one of our core priorities.

Cybersecurity is an ongoing organization-wide effort, with oversight from executive leadership and our Board of Directors.

“Advancing our defenses to stay ahead of evolving cyber threats and ensure reliable service for the communities we serve.”

We strengthened our preparedness through technical and executive level tabletop exercises that test incident response, escalation, regulatory notification, and business continuity protocols.

2.22M

cyber attacks defended

We blocked and detected more than 2.2. million cyberattacks, allowing us to maintain 100% protection of critical systems.

300

employees received cybersecurity awareness training

More than 300 employees received cybersecurity awareness, strengthening our human firewall and helping to protect critical systems and customer information.
