Measuring wind energy off the Lake Michigan shore

Scientists are analyzing new data that’ll determine whether offshore wind farms are viable in Lake Michigan and the data is more detailed than any available from the Great Lakes so far.

A floating eight-ton research buoy is collecting the data. There are only three such vessels in the world and this is the first one launched in the United States.

The buoy has been anchored about 37 miles off shore for about two months now. Recently crews retrieved the first set of data cards – with information about wind conditions and any bats and birds that fly by. Scientists are now analyzing that data.

Arn Boezaart heads the Michigan Alternative and Renewable Energy Center that’s operating the buoy. "I think we are getting data at this point that will be very useful and will validate the fact that the wind conditions at mid-lake are very promising for potential future use as a commercially viable wind source," Boezaart says.

But right now there is no clear path to proposing an offshore wind farm in the Great Lakes inside the Michigan border.

City of Holland decides winds not strong enough for wind farm

The City of Holland is backing out of plans for a potential wind farm. The city-owned utility bought the option to lease hundreds of acres in Allegan County after the state identified the area as one of the best in Michigan for wind energy potential.

But after more than a year of serious study, the city doesn’t think there’s enough potential to build the wind farm.

“When we went into this, everything looked like it was going to be a good project to pursue,” said Dan Nally, who directs business services for Holland’s Board of Public Works.

"We shouldn’t take the fact that this project doesn’t go forward that we are not supporting renewable, because we absolutely, positively are. But we will also, at the same time, get the best value that we can,” Nally said.

The wind was good, but not as strong as they had hoped. The plan was to have a 20 mega-watt wind farm-- relatively small compared to large scale commercial projects.

Nally says the utility has spent roughly $678,000 to collect wind data and study the impact on birds, bats and wetlands.

"We don’t feel that any of this money has been wasted. It’s been an investment in understanding what we could and could not do,” Nally said.

Nally says Holland is working on agreements to purchase renewable power from other wind farms, but he declined to give details until any agreement is negotiated.

Holland and all other utilities in Michigan must have 10 percent of their energy come from renewable sources like wind by 2015. Nally says Holland is still on track to meet that requirement.
