As wildfires become increasingly fierce across Canada, remote communities are bearing the brunt of electricity disruptions caused by damage to utility infrastructure. The devastation wrought by these blazes, particularly in regions like Alberta and Manitoba, has prompted urgent calls for innovative solutions to safeguard power lines and maintain reliability for vulnerable populations.
The Increasing Frequency of Wildfires
Each summer, Canada’s expansive electricity grid, primarily supported by wooden utility poles, finds itself precariously situated in wildfire-prone areas. In 2022 alone, more than a thousand utility poles were destroyed due to wildfires, leading to significant power outages in rural and remote communities. Such incidents have amplified concerns among utility companies, prompting them to explore more resilient infrastructures.
Jasper, Alberta, serves as a stark example of this growing crisis. Following the establishment of a new transmission line in 2019, the community became more connected to the provincial power grid. However, the Chetamon wildfire wreaked havoc in 2022, scorching around 6,000 hectares in Jasper National Park. This catastrophe not only damaged the power lines serving the town but also caused a week-and-a-half blackout for residents. In 2024, a more intense wildfire left many without power for up to 16 days, highlighting the fragility of the existing electrical system.
The Struggle for Reliable Power
Mayor Richard Ireland of Jasper described the town’s power situation as akin to a “tentacle” rather than a robust grid. The reliance on a single power line leaves the community vulnerable to outages, which can have devastating effects, especially in a region reliant on tourism. During the 2022 wildfire, rolling blackouts and backup generators were implemented, but the impact on local businesses and residents was severe.
The situation was echoed in British Columbia, where the Kelly Lake substation fell victim to a wildfire in July, causing disruptions for customers many kilometres away. B.C. Hydro reported losing 115 distribution poles and two transmission structures due to fire damage. Such incidents underscore the interconnected nature of electricity supply, where the failure of one link can reverberate throughout the network.
In Manitoba, the O-Pipon-Na-Piwin Cree Nation faced a three-week outage after wildfires damaged their power lines. The community, reliant on generators and limited fuel deliveries, experienced considerable distress, particularly among members with health conditions requiring consistent power, such as those needing dialysis or respiratory support. The restoration process was complicated by difficult terrain and ongoing wildfire threats.
Innovation in Infrastructure
In light of these challenges, utility providers are increasingly adopting innovative strategies to mitigate wildfire risks. In British Columbia, wooden poles are treated with fire retardants, and in high-risk areas, they are being replaced with materials like fibreglass-reinforced polymer or steel. Moreover, wildfire-resistant mesh has begun to cover thousands of poles to insulate them from heat, a proactive measure that has gained traction since the devastating Fort McMurray wildfire in 2016.
ATCO Electric has also embraced similar strategies, with about 10 per cent of its distribution network now protected by this mesh. The company’s vice-president of engineering and construction, Gurb Hari, emphasised the importance of balancing public safety, reliability, and affordability. While burying power lines would eliminate wildfire risk, it would also incur substantial costs that could affect consumer rates. Instead, the focus has been on effective, cost-efficient solutions.
Why it Matters
The ongoing threat posed by wildfires to Canada’s remote communities is a pressing issue that demands immediate attention. As climate change exacerbates the frequency and intensity of these natural disasters, the need for resilient power infrastructure becomes paramount. The current vulnerabilities not only disrupt daily life for residents but also jeopardise the health and safety of those reliant on electricity for medical care. As utility providers and governments grapple with these challenges, the time has come for a concerted effort to innovate and fortify the systems that underpin these communities, ensuring they remain connected and safe in the face of growing environmental threats.
