Maintaining wood poles
Extending the life of wood poles
Our electrical system depends on wood utility poles. We want them to be strong and stable to keep you safe and to reduce the number of outages caused by pole failures.
We regularly inspect the wood poles used in both the transmission and distribution of electricity throughout B.C. Our inspectors look for signs of damage from insects and birds, and for evidence of rot. When necessary, we use pesticides and wood preservatives to treat poles.
Untreated poles can last for about 30 years. A pole treated with wood preservatives can last up to 70 years.
