http://www.startribune.com/local/269682291.htmlXcel Energy's Chief Executive Officer Ben Fowke wrote in a July 23 letter to the federal Surface Transportation Board that rail carrier BNSF has fallen behind on coal deliveries to the 2,500-megawatt Sherco plant, according to the La Crosse Tribune (http://bit.ly/1zI7oks ). The plant, about 45 miles northwest of Minneapolis, generates nearly a quarter of the electricity Xcel delivers in a five-state Midwest region.
Xcel Energy is urging the board to focus on getting railroads to reduce a shipping backlog that could "impact the reliability of our electric grid."
BNSF is the sole rail service to the plant, which can serve some 1.9 million homes, according to Xcel.

The Sherco plant is now 811,000 tons short on its ideal inventory, is not set up to burn natural gas, and, though it will continue generating base load power, could fail to meet a peak demand event.
Utilities served by BNSF in Arkansas, Kansas and North Dakota have reported similar problems. Generation and transmission co-operative Dairyland Power said its coal supply is at "perilous levels" and falling further behind.
Bottom line: the rail lines are so busy hauling Bakken oil, they have no extra capacity for coal.
Maybe this will accelerate the deployment of more wind here in the Midwest.

(6,279 posts)Last week I heard talks by executives from some smaller regional utilities, one serving western Minnesota and the eastern Dakotas, the other all in Minnesota. The guy from the first utility made it pretty clear that, while as an operator he was thrilled to buy cheap electricity from wind, deep down he was a fossil fuel guy. His company also faces the challenge that Minnesota asks utilities to consider greenhouse gas emissions in crafting their fuel mix while one of the Dakotas actually has a law against doing so! The other utility already has a fairly high fraction of wind in its portfolio, has a deal to do some pumped storage in Manitoba... but their problem is that many of the rules under which they get credit for decarbonizing their electricity only give them credit for projects located within the state! And they like to put wind projects in the Dakotas because the wind is better there...
