We were “Sooners”
on this day. We arrived at 11:15 instead
of the 11:45 on the invitation. We had
permission. It was NextEra’s Ribbon
Cutting ceremony marking the near-completion of the windfarm. We were among the first to tour the nearest
wind tower.
You can see the
first landing. Two more above that. The elevator doesn’t work too well, so use
the ladder at right. They didn’t offer
to let us climb it. I didn’t feel much
like it anyway, suffering from my head cold.
Our electrical
engineer kept the hosts occupied for nearly an hour. Listening in was quite interesting, even if I
didn’t understand a lot of it. The wheel
turns from 12 to 20 rpm. A step-up gear
box converts that to 1000’s of rpm needed to turn the generator. Maintenance
includes checking and changing oil in the gear box.
At 12 rpm, the
tip of the blades are traveling about 130 mph.
Voltage is
stepped up to the thousands of volts at the sub station. Don’ touch that wire.
The MET tower,
among other things, alerts techs to static electricity in the vicinity. If the
level gets tool high, they must exit pronto as a lightning strike is a good
possibility. Wouldn’t want to be in that tube when a bolt of lightning hits. If you survived the strike, the thunder would
ruin your ears and several other parts of your anatomy.
Land owners were
the special guests, so time to meet up with the neighbors. And then there were the speakers.
Here they all are
playing with their miniature wind generators, their reward for having been
guest speakers:
Left to right: NextEra CEO Pimentel, State Rep. Gardner,
County Commissioner Beedy, Public Service Exec. Eves, and of course, Governor
Hickenlooper.
Here they all
are having just cut the ribbon. Now the
wind can blow, bearing man’s harness and serving his will. Maybe.
