There is currently a coal fired power plant on Big Stone Lake in South Dakota on the Minnesota/South Dakota border. The permits received from both federal and state were to build a second plant, and to update and remodel the existing plant. The result would be doubling the power output and increasing polution a very minimal amount over the current plant (the result of new technology for efficiency and cleanliness being used in both the retrofit of the esisting and in construction of the new).
More than twice the power with negligable increase in "greenhouse" and other emissions. Sounded like a good deal to us.
The "tree huggers could not stop the plant on either the federal or South Dakota permits, so they attacked in Minnesota. What they did was work through the Public Utility Commission (PUC) trying to show there was no need for the power lines that were a part of this project. They wanted the lines for the wind that is going in all over western Minnesota, so they fought to keep the lines from crossing into South Dakota.
The straw that actully took Ottertail out of the picture was that the PUC ruled that the added costs associated with new agreements for abating pollution could not be passed on to the consumers. Most of the rest of us as utilities could include it as a cost of production (or true wholesale cost) and charge accordingly. However, Ottertail was restricted to what they could charge or pass on.
This ruling was in affect saying that this plant and transmission has a three cent per kilowatt wholesale cost delivered to the utility, but since one cent of this is for abatement agreements on pollution you can only mark up based on a two cent cost. This actully set up a situation where the utility could not mark up the power at all.
To put this in terms that many of us could understand, and bites Haz in the shorts, it is like telling Haz that his truckers can only charge for fuel, oil changes and tires. However, they can not charge for wear and tear on the tractor, because it was purchased special to reduce both fuel consumption and emissions.
The most recent attack on the Second Amendment that mirrors this move is the OSHA situation of a couple years ago.
