An investigation into what caused the collapse of a wind turbine at New Brunswick's largest wind farm has revealed serious structural issues that affect not only the turbine that fell, but dozens of others in the area as well. According to TransAlta Renewables Inc., the Alberta-based company that owns and operates the Kent Hills wind farm, the cracks formed because of "deficiencies in the original design of the foundations."
TransAlta Renewables Inc. said replacing 50 foundations will cost C$75 million to C$100 million (US$59 million to $79 million) and take until the end of 2023. The Calgary-based company expects to lose C$3.4 million per month in revenue while the turbines are off line, according to a statement Tuesday.
Based on initial estimates, TransAlta says the replacement of the foundations at its Kent Hills 1 and 2 wind sites is expected to cost between $75-million and $100-million. It also estimates it will result in foregone revenue of about $3.4-million per month on an annualized basis for so long as all 50 wind turbines are off-line, based on average historical wind production.
TransAlta Renewables Inc. lowered its financial guidance for this year as it said it has found cracks in several foundations of the turbines at a wind farm in New Brunswick where a tower collapsed earlier this month.
TransAlta Renewables Inc. says it has found cracks in several foundations of the turbines at a wind farm in New Brunswick where a tower collapsed in September. The company says the discovery of the subsurface cracks means the foundations will likely need repairs, and if replacement is required, costs are estimated at $1.5 million to $2 million per foundation.
"The cause of the incident is under investigation," TransAlta spokesperson James Mottershead said in an email to CBC News. The area surrounding the wind facility has been closed while the investigation is underway. ...According to the company's website, the Kent Hills wind farm is the largest wind facility in the province, with more than 50 wind turbines.
For the first time, Naveco's CEO Amit Virmani tells CBC News he is looking at moving the project out of Anse-Bleue, and out of northern New Brunswick altogether. ...That would require NB Power to agree to amend its existing contract with Naveco to buy 20 megawatts of electricity from the Anse-Bleue site.
Wind farm proponent says he's baffled by seemingly contradictory positions on environmental issues, projects
A planned wind farm in the Bathurst, N.B., area was struck a major blow on Monday. City council withdrew an application for funding for the Chaleur Ventus Energy Project planned for Anse-Bleue.
The City of Bathurst is the leading partner in a proposed Acadian Peninsula wind farm that's drawn the ire of nearby residents. The city has sought provincial approval to borrow up to $20 million for the project about 56 kilometres northwest of Bathurst, but councillors won't talk about it.
Canadian utility Emera has proposed exporting power from 1.2GW of future onshore wind farms in eastern Canada via a subsea cable to Massachusetts, to help the New England state meet its mandated renewables target.
Indications are mounting, however, that green capitalism will not be able to meet all expectations. In courts around the country, complaints are mounting from wind park investors who haven't received a dividend disbursement in years or whose parks went belly up. Consumer protection activists are complaining that many projects are poorly structured and lack transparency.
