Reliability & Resiliency

Reliability means more than keeping the lights on for our residential and business customers. It also means planning for the future and modernizing our electricity grid to meet the demands of electrification and the needs of one of the fastest-growing communities in Canada.

We invested $53 million in capital projects in 2024. This investment replaced end-of-life equipment and added new technology to improve reliability. We also made significant upgrades to our No. 5 Transformer Station to expand capacity in the east side of Kitchener. The hard work of our Engineering and Distribution crews helped decrease momentary outages by 7%. At the same time, we saw an additional 24 MW in peak demand, reaching a system peak of 660 MW on June 19, 2024.

Proactive replacement of end-of-life assets and investments in automation and new technologies helped improve grid resiliency and ensure we’re prepared to welcome an influx of large customers and new business opportunities. We maintain more than 200 smart switching devices in our system, and our Fault Location, Isolation, and Service Restoration technology continued to improve our average restoration time.

Diligent vegetation management and tree trimming helps ensure a healthy tree canopy without compromising reliability or safety by keeping branches and foliage away from powerlines and electrical equipment, limiting accidental tree contacts.

Innovation

We’re prepared to meet the combined challenges of powering a growing region in an ever-changing energy landscape. We’re positioning ourselves as leaders in new technologies and exploring new ways of doing things. We’re embracing grid modernization, technological development and local partnerships to develop what’s next in support of our business and residential customers.

To meet growing demand for electricity due to electrification and the increased penetration of Distributed Energy Resources (DERs), in 2024, we partnered with GridS2 to conduct a Distribution System Operator (DSO) study and pilot a demonstration lab.  The goal of the study was to quantify the benefits of forming a DSO by evaluating the impact to customer electricity costs, the additional revenue stream to DER owners, and operational and financial benefits for Enova.

We also implemented a lab-based demonstration at our Victoria Street office showcasing the operations of a real-time DSO, including accepting bids from market participants and optimal scheduling of DER assets while ensuring grid reliability. The case study was presented at the Electricity Distributors Association 2024 EDIST Conference and the lab-based demonstration has been operational since mid-2024 with the final report to be completed in 2025.

Protecting Data

Cyber-threats are evolving and becoming more invasive and sophisticated. Protecting customer data and our electrical system is a foremost priority.

Protecting customer data and the security of our network and system assets is an around-the-clock job requiring continuous evolution and improvement. Our Information Technology team is vigilant, and their focus on security resulted in a 99.7% system reliability in 2024, meaning the critical information systems essential to how we do business and support our customers were unaffected by system attacks.

The fast thinking of our Information Technology team and the resiliency and security of the systems we have in place were evident during the Crowdstrike outage. Facing a global IT outage that impacted everything from email to airplanes, we successfully brought impacted systems online within a day, minimizing customer inconvenience and frustration.

Fault Location, Isolation and Service Restoration Project (FLISR)

FLISR allows SCADA-controllable devices to automatically activate when a fault is detected. This activation automatically reroutes power to restore as many customers as quickly as possible after an outage. Later this year, the system will also monitor the network for sudden loss of voltage and attempt to isolate the cause and reroute power to as many customers affected as possible.

For more information on FLISR and its impact on reducing outage minutes across Enova’s service territory, visit enovapower.com/innovation.
