Fixing a Wind Turbine: No Small Matter

This week’s Chronicle includes a story about Carleton College’s three-year-old wind generator, which broke down recently. The two-month process of fixing it involved finding a crane tall enough and heavy enough to remove the giant blade assembly from the top of the 230-foot tower. The pictures above and below, taken by Weldon Hogie of Northfield, Minn., should give a sense of just how big a job this was. (Thanks, Weldon, for letting us run them.)

The story includes comments from a wind-industry expert who says colleges should prepare for expensive and difficult repairs if they decide to invest in wind turbines. It should be noted that officials at Carleton College have not soured on their turbine, despite its recent breakdown. The machine was under warranty, so the manufacturer covered the repairs.

High winds, which could have made work on the wind generator dangerous, delayed repairs. The crane was on site almost three weeks, at a cost of $5,000 a day.
