Basin Electric, together with the North Dakota Association of Rural Electric Cooperatives; and Great River Energy, Elk River, MN; have combined to donate $1.3 million for the expansion of the North Dakota Heritage Center in Bismarck. This gift has resulted in the Touchstone Energy Cooperative Governors Gallery which will feature traveling exhibits.

Traffic is heavy on the Dry Fork Station plant site. Crates coming in from Korea carry the pieces for the power plants transformers.
Wheatland T-S-Ms Kevin Ven Huizen and Tyler Lindholm are unpacking bushings, radiators, everything that will be attached to the Generator Step-up Transformer.
Several T-S-M crews have just finished putting the pieces on the reserve auxiliary transformer.
(Bruce Wolff/Wheatland TSM): All the guys know this stuff pretty well. But to assemble one from the start, it was a learning experience.
Its here in the generator where the mechanical energy made by the steam turbine is converted to electrical energy. The electricity moves down a floor, to the isophase bus duct. Inside that, theres a conductor thatll move the power out of the building to the generator step-up transformer. So the power moves through the isophase bus duct which will be coming through that square cutout you can see on the side of the building to the G-S-U, the generator step-up transformer. At that point, the power is stepped up to 230,000 volts of electricity. From there it moves to the plants substation, where most of the power heads out onto the transmission grid. However, some of it will head back toward the plant to the RAT, the reserve auxiliary transformer, which is sitting there right to the left of the GSU. At that point, the power is stepped down to 13,800 volts. The electricity goes into the plant to be used for things such as lights, motors, fans and computers.
Bruce Wolff works for Wheatland T-S-M. What theyre doing is called dressing the transformers.
(Bruce Wolff): We installed all the radiators, the fans, the lightning arresters, the brackets, the bushings, those bushing towers, the conservator tank
It takes a dozen people about a month and a half to dress both the Generator Step-up and the reserve auxiliary.
(Bruce Wolff): Weve worked on lots of them, where weve changed gaskets and changed bushings and a lot of this stuff. But weve never totally dressed one out like this before.
The transformers play a big part in getting electricity to where its needed whether thats in a home or in the plant.

A video look at the last day of building a wind turbine.
Temperatures were in the single digits on the day the final rotor of the PrairieWinds 1 project was set.
The reason it didnt happen until Friday, Dec. 4, was because a blade was missing. A truck driver had backed into the final blade earlier, damaging it beyond repair. So, GE had to send a new blade, which took a few days. The blade arrived on site after 2:00 p.m. on Friday.
Once the blade was on site, crews had to attach the blades to the hub, which together is called the rotor.
Because the temperatures were so cold, the crews used diesel heaters to pump warm air into the turbine. The heat rises to the top, making the job a little less chilly. While the air temperature was about 5 degrees, the heater will warm the air about 20-30 degrees.
Once the last blade was on site and it was connected to the hub, crews needed good weather conditions to lift the last rotor. This one was set at about 9:00 p.m. that night.
Once all the rotors are set, crews need to do generator alignments. That can only be done when wind speeds are 16 miles per hour or less. Once the last 10 are complete, the turbines receive a mechanically complete certificate.
Now, GE needs to commission the turbines, which means doing more wiring and other finishing work inside the turbines. From now until the end of the year, a few turbines at a time will go on-line. That means theyll be making electricity and putting it on the grid.
Each turbine has a generating capacity of 1.5 megawatts. Even though Minot Wind 2 and PrairieWinds 1 are two separate projects, the turbines for each project are exactly the same. Construction on both projects began on August 10 and 18, respectively, this year.

The Basin Electric pilots get an inside look at Dry Fork Station! Mark Burke and Craig Goeden were gracious enough to take our Flip Camera, and give us a new perspective of the plant. They're flying people to Dry Fork Station all the time - it's about time they see the inside!
