BC Hydro will be replacing more than 9,000 wooden poles across the province, including 340 in Nanaimo, over the next few months. According to BC Hydro, power poles last 40 to 50 years on average but deteriorate over time due to adverse weather, insects and wildlife. There are currently 900,000 wooden poles in B.C. that hold more than 58,000 kilometres of overhead distribution lines and 278,000 overhead transformers. The utility said it may need to disconnect power when it is replacing the poles to ensure the safety of crews and the public. Crews will notify people in-person, by mail or phone about scheduled outages for maintenance. Most of the old wooden poles will be recycled. A contracted supplier will sort and recycle the wood poles.
