The 10 wind turbines at the Taconite Ridge wind farm will probably still be motionless until early February, a company spokesperson said Thursday. Nine of the ten wind turbines now are having repairs done to blades, instead of just five, that was reported earlier. The completion date for repairs has been pushed back from mid-January, said Amy Rutledge, Minnesota Power communications manager.

When it came time to start repairing a wind turbine at the ethanol plant on Oct. 15, the project had to be put on hold. ..."The blade has been cracked all summer. It's been frustrating," says Dan Moore, director of project development for Renewable Energy Solutions. When the broken blade was discovered, the turbine furthest from the ethanol plant had to be shut down. All three blades needed to be replaced, says Moore, because we couldn't find one to match the other two.

It's not just a lack of wind as the reason why some of those wind turbines in the Taconite Ridge wind farm aren't turning. Half of the 10 machines had to be turned off. After a recent routine maintenance check, it was found that five of them had non-structural defects in some of the blades. The affected turbines were shut down and are awaiting repairs, which are expected to go through the end of the year, Amy Rutledge, Minnesota Power communications manager, said Friday.
