With coal supplies dwindling at major power plants, Xcel Energy and other electric utilities are putting increased pressure on BNSF Railway to increase deliveries from western mines.
Some power plants, including Xcel's giant Sherco station in Becker, Minn., are generating at reduced levels to conserve coal inventories. That prompted Ben Fowke, CEO of the Minneapolis-based utility, to ask federal regulators last month to focus on boosting coal supplies.
In La Crosse, Wis., Dairyland Power said one of its power plants that serves part of Minnesota could be forced to shut down in January for lack of coal. Rep. Tim Walz, D-Minn., and Sen. Chuck Grassley, R-Iowa, recently wrote to the U.S. Surface Transportation Board urging action to help Dairyland, a wholesale power cooperative that serves four states.
The coal-supply problem surfaced late last year, as BNSF and other railroads struggled to haul a record corn crop, more consumer goods and increasing numbers of tank cars filled with crude oil. Then came the winter's polar vortex, slowing down everything on the rails.
"It doesn't seem that it has improved that much, if at all," said Paul Gutierrez of Consumers United for Rail Equity, an advocacy group for utilities and other companies on shipping issues.
Gutierrez, an executive with the National Rural Electric Cooperative Association, said cooperative utilities in Kansas and Arkansas have recently reported coal shipping delays. Xcel said its Texas power plants also have been affected.
In Minnesota, coal stocks at power plants were down 22 percent in May compared with five-year average levels for the month. It was the lowest pre-summer stockpile since 2002, according to the most recent U.S. Energy Information Administration data.
"Our network has had some significant challenges this year, including historic weather conditions and increased growth in volumes across a number of sectors," BNSF spokeswoman Amy McBeth said in an e-mail. "We continue to see some gradual improvements in service for customers along our Northern tier as new capacity comes online."
