An accident on Roxul's Grand Forks site knocked out power to Christina Lake and Grand Forks on Oct. 12.
"We have routine maintenance on our site and an employee accidentally touched a tree with a loader," explained Leslie McLaren, corporate communications manager for Roxul.
"The tree was old, it wasn't very well rooted and as a result of the accidental contact, the tree fell over on a power line, resulting in the power outage."
McLaren said Roxul contacted Fortis BC immediately in order to remove the tree and restore power.
"That was our top priority to (contact) Fortis and make sure that power was restored as quickly as possible," she said.
"The safety of our employees and the community is a top priority for Roxul, so we're committed to ensuring that a similar situation to that doesn't happen again."
Shortly after power went out, a message on Fortis BC's hotline said that Christina Lake and Grand Forks were the areas affected and a message at 2:10 p.m. on Oct. 12 stated that power had been restored to the lake while Grand Forks was still experiencing an outage.
"At approximately 1:30 p.m., we experienced an outage on our system that affected all customers in the Christina Lake area and some customers in Grand Forks," Fortis BC spokesperson Neal Pobran told the Grand Forks Gazette at around 3:40 p.m. on Oct. 12.
At the time, he confirmed that power had been restored to Christina Lake and power to Grand Forks, if not already restored, would be back within an hour.
Pobran said that approximately 1,800 customers were affected by the loss of power.
