Behind the Scenes of Power Restoration: how we work on continuously getting better

March 29 2021, 10:00 AM

We know how difficult it can be when your power is out. That’s why we continue to look at ways to improve our processes so we can be there for our customers when they need us the most.

NB Power is responsible for making sure customers have the power they need when they need it, in good weather and bad. We take this responsibility very seriously. With more than 20,000 km of distribution lines and close to 7,000 km of transmission lines, our electricity infrastructure covers a vast expanse of terrain.

Our province and our infrastructure is increasingly subject to severe weather brought on by climate change. Hurricanes, ice storms and two of the worst floods in the past 50 years are some of the extreme weather events that New Brunswick has faced in the past decade. As storms become more intense and cause major disruptions in many parts of the province, NB Power’s storm preparedness effort, conducted in collaboration with partners, has taken on greater significance and urgency.

Every year, we collaborate with the province’s Emergency Measures Organization, the Canadian Red Cross, and other partners, to emphasize the importance of being ready for storms for New Brunswickers. This approach is considered a best practice and aligns with provincial and federal agencies who adopted the integrated emergency response model.

We also have an Emergency Response Plan in place. This plan helps to ensure consistent preparedness, response, communications, and recovery practices across our entire organization. This approach in any emergency response is effective, efficient and ensures the safety of customers, employees, contractors, and the public.

Our Emergency Planning Management team is centralized for proactive decision-making and strategic planning ahead of, and during, an event. For each event, we set up local centres in affected regions to monitor outages, realign crews and reduce restoration wait times for customers.

Vegetation management is also an essential part of reliability efforts: pruning trees, removing brush, and clearing power lines help keep them free to deliver safe, reliable electricity. In the last fiscal year, we invested $5.8 million in inspecting and clearing over 1,200 km of distribution lines. We invested a further $4.4 million inspecting over 2,300 km of transmission right of ways and subsequently treating approximately 1,400 kms of those right of ways. In addition, we invested over $62 million in our transmission rebuild program, completing several life extension and storm hardening projects.

Our annual maintenance program also helps identify and respond to issues. 20 per cent of our utility poles are inspected annually, as part of a five-year cycle. A maintenance plan is established for aging poles, and our field crews perform the work to maintain the safe operation of our electrical grid. Every spring a system review of power quality is performed to establish short and long-term goals for our power supply equipment. From the reviews, NB Power then establishes a detailed plan for the following year.

These are just some of the things we do to provide electricity safely, in good weather and bad, for all New Brunswickers.
