Wind Turbine Erected

The three sections of heavy duty steel tower will rise a total of 124 feet above the river.

Crane power and man power began installation in Fair Haven Monday morning of the largest wind powered turbine in Connecticut. Crews hoisted into place the first of the three sections of the tower on the waterside property of Phoenix Press near the cul de sac where James Street meets the Quinnipiac River.

A construction crew from Alteris Renewables of Danbury and Boston used guide ropes and the luck of gentle wind conditions to position the tower over its base: 100 threader rods that rise up through a footing of 12 feet of concrete.

The task was then to lower the tower slowly, very slowly in order to get the 100 rods to match up exactly with the 100 holes in the tower’s base.

Led by site supervisor Phil Smith and senior field technician Thor Thomforde, the job was done within a half hour

The first section must settle for 24 hours into a kind of slurry of cement that joins it to the base.

On Tuesday, weather permitting, the other two sections will be added. The upper sections, like the base, will be bolted one to the other, by a worker who descends the ladder that runs the entire length of the tower’s interior. He’ll be bringing equipment with him so he doesn’t have to turn 100 huge bolts by hand.

When the tower’s complete, the nacelle will be lowered onto the top of it. The nacelle houses the turbine that converts the kinetic energy provided by the wind into electricity. Electricians Rick Esposito and Louis Messier were attending to thejuice. A line had previouisly be laid underground running from the turbine to the Phoenix Press buildings 25 yeards away..

This is the rotor that will attach to the nacelle tomorrow.

The three blades of the turbine will each then be attached to the rotor. While the tower units were made in China, the blades were manufactured in California, said Thomforde. They are each 35 feet long and Monday were resting on a truck waiting their turn for installation.

When the nacelle and blades are added, the total height of the tower will be 156 feet.

When the turbine is operational next month, Brian Driscoll, one of the partners at Phoenix Press, estimated. he’ll be able to offset a third of his company’s electricity bills. The Connecticut Clean Energy Fund contributed half the $500,000 cost of the turbine.
