Wind farm turbine repairs begin this week

Work will get under way this week to repair a wind turbine damaged by a fire last month at the Kent Hills wind farm in Albert County, roughly 30 km southwest of Moncton. One of the 32 wind turbines at the site caught fire on the morning of Aug. 8, and it's been offline since.

Work will get under way this week to repair a wind turbine damaged by a fire last month at the Kent Hills wind farm in Albert County, roughly 30 km southwest of Moncton.

One of the 32 wind turbines at the site caught fire on the morning of Aug. 8, and it's been offline since.

Despite this, an NB Power spokesperson says the fire hasn't caused them any sort of grief and things are "business as usual" for the corporation. NB Power has a 25-year contract to purchase wind power from TransAlta Wind of Alberta, the owner and operator of the site.

This time of year isn't considered a peak wind season, so having one of 32 turbines down isn't a big deal.

Jason Edworthy, director of communications for TransAlta, confirms this.

"It's sort of a low-wind season. There's been some production lost but, because it's not the windy part of the year, it's not going to have a huge impact," he said in an interview yesterday.

Edworthy says the cause of the fire is still unknown. Some local residents suggested it may have been caused by lightning, but Edworthy says that option has been ruled out.

Edworthy says the cause of the fire is still unknown. Some local residents suggested it may have been caused by lightning, but Edworthy says that option has been ruled out.

He says technicians are working to determine the cause, so he's not sure at this point whether the damage will be covered by insurance or warranty. The amount of money or power lost due to the incident hasn't yet been determined.

A single turbine, manufactured by a company called Vestas, is estimated to cost between $4 million and $5 million.

A new nacelle, which holds the wind turbine's power generation components, was expected to arrive in the province on Saturday, while three new 45-metre-long blades were due to arrive at the Kent Hills wind farm sometime this week.

The turbine's tower is fine, other than some scorching, which has been painted over. The parts landing in Metro this week were intended for a wind farm currently under construction in Alberta, but they were diverted to Kent Hills instead.

When a new wind farm project is launched, there is usually about a two-year wait to get the necessary turbines from Vestas, and it would have taken some time to get a spare one for Kent Hills had they not diverted one from the Alberta project.

Edworthy lays to rest any concerns that the incident could be a sign of growing pains for the new wind farm, which has been in operation only since Dec. 31 of last year.

Edworthy says it takes a few days of setup before the wind turbine can be installed and then it should be about another week before it's back online.
