The wind industry is hiding a dirty little secret about gearbox failures. Gearboxes on top of the towering masts have short shelf lives, often out before even five years is up. The gearbox failures have led to catastrophic failure.
June 26,2012﻿ the Town of Portsmouth is waiting to hear back from the gearbox manufacturer about the break downs . The turbine has been off most of May and June . The cost of a gearbox : Special crane,parts,labor,down time about 1/2 million. Turbine 3 years old !
The National Geographic Channel needs to do a follow up story on the fiasco going on at the Portsmouth High School Wind turbine. The turbine was featured on﻿ "World's Toughest Fixes" - The turbine (three years old ) has an awful history of failures and may soon need hundreds of thousands of dollars in repairs .
The turbine is a little over three years old ,has a major breakdown at least each month now .It is having trouble with its oil sensor in the gearbox . This looks to be a nightmare !
