During the early years of the North American Wind Industry, the general misconception regarding blade maintenance was that once the blades were in the air, routine maintenance was not required. As the industry matured, some tough lessons were learned. Maintenance, especially on the leading edge of the blade, is not only recommended but essential if blades are to reach their design life expectancy.
Just three years after they were installed, the wind turbines at Bear Mountain are getting an upgrade. Starting this summer, AltaGas will be replacing the blades on the 34 wind turbines at the Bear Mountain Wind Park.
One of the broken blades remains attached to the tower. Debris from the blades is on the ground around the turbine. Officials with Qulliq Energy Corporation aren't sure what caused the damage, or if it will be repaired.
While Windshare's original investors split dividend payments of $32,000 from the sale of power in 2005, profits since then have been ploughed back into the turbine for maintenance, Ms. Saxe said, adding the bearing replacement will cost $200,000.
For 2010, the turbine had revenue of $58,439, and rang up maintenance costs of $18,291. It didn't release statements including interest, taxes, depreciation and amortization. The current repairs will cost more than $200,000. The turbine's initial cost was $1.8 million.
Nearly all of the 22 turbine foundations at Nova Scotia Power's Nuttby Mountain wind farm are cracked, CBC News has learned. "Wherever we identify cracks, they are being addressed. I think right now we are at 19 of the 22," NSP spokesman David Rodenhiser said Tuesday.
Ian Tillard, chief operating officer for Shear Wind, said it took about an hour for the fire to burn itself out. ...He acknowledged the company will have to work with local firefighters in the future about responding to such situations.
The exact cost to fix the problem wasn't known Wednesday evening. Faith said it's unlikely the information would have been provided to the power company. Because the farm was up and running ahead of schedule, Faith doesn't believe the downtime required to fix the five turbines will "have a dramatic impact" on the utility's energy goals for the site.
There are problems with the foundations of at least five of the 22 wind turbines installed this past summer at Nova Scotia Power's wind farm on Nuttby Mountain, north of Truro, CBC News has learned. Three of the turbines are shut down for repairs because the 400-tonne concrete pads were improperly installed.
"There is supposed to be a little movement." The repairs, which consist of filling the "very minute" gaps between the base and foundation with a type of epoxy, are being done under warranty by the supplier. Faith said it takes three days for the repairs to be completed
For the third time since it went online, the wind turbine at the RCMP detachment in West Amherst is on the fritz. ...The turbine, which cost $225,000 to erect, broke down during a 2007 electrical storm and failed in 2008 after a fire in an electrical panel.
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.
TransAlta Corp. is still investigating what caused a fire last month that destroyed one of its turbines at the Kent Hills Wind Farm, a company spokesman says. ...Lightning has been ruled out as a factor in the Aug. 8 fire.
New Brunswick's first commercial wind farm will lose several weeks of electricity output from one of its 32 turbines after a major fire damaged the towering structure on the weekend. The blackened shell of the wind turbine, much of its white coating peeled away, was obscured by fog and clouds at the TransAlta wind farm in Albert County.

One of the 32 wind turbines operating at the Kent Hills wind farm caught fire over the weekend. ...A passer-by saw smoke and called the fire department. Officials haven't been able to confirm the cause of the fire yet. Vestas, the company that supplies the turbines, will have a team on site today to try and determine what happened.
TransAlta Corporation today announced at approximately 8:00 am (eastern time) a fire occurred at a single turbine located at its Kent Hills wind farm in New Brunswick.
Two of the turbines at P.E.I.'s $47-million wind farm in East Point are under repairs for the second time in just over a year. The V-90 turbines - named for their 90-metre blade span - are having problems with their gear boxes, the same thing that took them down last spring. ...MacQuarrie said Vestas, the manufacturer of the turbines, is still refining the gearboxes.
What we can't see from Kingston, but what one island neighbour told me is among the biggest changes to their lives, is the noise. When the wind is up, "it sounds like a jet engine coming through -- and they're not all up and running yet."
Bill Fish wants the Municipality of Chatham-Kent to investigate homemade windmills after his neighbour's device came crashing through his roof during yesterday's high winds. He was shocked awake around 3 a.m. when an eight-foot-long wooden blade penetrated the roof, before piercing through the ceiling and wall in a sewing room of his Dufferin Avenue home, located outside of Wallaceburg in Chatham Township.
