April 30, 2008 – Wind Turbine Foundation Poured!

After the 3rd scheduled attempt, today was finally dry enough to get a cement truck with 5 yards of cement back to the wind turbine site without sinking out of sight.

Todd and James set the layout for the tower and four guy wire supports. A perfectly flat site is ideal, but hard to find, even in Iowa.

Setting the auger in the appointed location to dig out the first footing.

Great fertile, black Iowa soil coming up from the deep.

Setting and leveling the form for the footing.

Martin takes a peek down into the ground.

All five holes are laid out and dug out, waiting for the cement truck to arrive.

The bottom 1/4 or so of the hole is filled with cement.

The rebar form is set into the hole.

Cement is tamped in as the hole fills up.

Final finishing and troweling of the top of the footing.

The tie-down bolt for one of the guy wires is set into the footing.

The finished footing. Now we wait for 30 days or so for the footing to cure before arranging a time for the tower to go up.

It was a bit of a symbolic day to install the wind turbine footings as it was also the day the Iowa Utility Board approved the construction of a coal-burning power plant 15 miles away from us. The permit did come with some aggressive conditions, including 10% biomass fuel in the plant, and a 25% renewable portfolio for the power company by 2028 and 10% before the plant is built.
