Towers located northwest of Green Mountain

GREEN MOUNTAIN – A total of 19 more wind turbines are popping up northwest of Green Mountain in the latest wind farm project in Marshall County.

Work started last month and has been progressing lately on the turbines, which are a project of MidAmerican Energy. The work is being done by the contractor Wanzek Construction of Albert Lea, Minn.

“I think their goal is to have them all in the air by Thanksgiving,” said Paul Geilenfeldt, Marshall County engineer.

He doesn’t believe the project will be hampered when the ground freezes.

“All 19 foundations are poured,” Geilenfeldt said.

This is the second phase of the Vienna wind farm project, which spans the northeastern edge of Marshall County and portions of western Tama County.

Geilenfeldt said he was on site recently and witnessed workers moving a 1.3 million pound crane they are utilizing to erect the towers.

“It’s the biggest crane I’ve ever seen,” Geilenfeldt said.

Upon completion, the 19 new turbines will bring the total wind turbines in Marshall County to 92, Geilenfeldt said.

MidAmerican has more than 1,000 turbines in the state and continues its investment in the field, taking advantage of wind energy tax credits.

Abby Bottenfield,, spokesperson for MidAmerican, said the energy generated from these turbines goes to their Iowa customers first and the excess is sold off.
