Coal Supply Disruption Threatens Operations at North Dakota Plant

News release from the Basin Electric Power Cooperative:

Bismarck, N.D. – Curtailment plans are being formulated at Missouri Basin Power Project’s Laramie River Station in Wheatland, Wyo., because the rail transportation system has not been delivering the fuel required to keep the plant operating at full production. Since May of 2005 deliveries out of the Powder River Basin to all utilities have been highly sporadic.

Basin Electric Power Cooperative is the operator of and part owner of Laramie River Station. Ron Harper, Basin Electric’s CEO and general manager, said “the reduced rail deliveries aren't a result of a lack of supply or ability to produce coal in the Powder River Basin; it’s simply a lack of rail transportation of coal to Laramie River Station. We are concerned about a decline in service and efficiency.”

Maintaining full generation levels at the 1,650 megawatt, three-unit station requires 24,000 tons of coal per day, which is what BNSF Railway is normally scheduled to deliver. Just to match daily consumption, LRS needs the equivalent of one-and-a-half trains per day. (A train consists of about 136 rail cars, each carrying about 120 tons of coal.) In addition, a stockpile is maintained at the plant site, which is used as backup in case of an interruption in rail deliveries. Today, the stockpile contains less than six days of operation at full production.

“In order to conserve our stockpile and maintain at least some production at the station, we are currently determining how to reduce production levels in the event curtailment becomes necessary,” Harper said. “Even though there’s enough demand for all three units to operate at full capacity, we want to conserve coal to be able to perform during a severe cold snap, for example. We are doing everything we can to continue full production, including adding a fourth train set and purchasing coal from mines closer to the plant to reduce transportation cycle times.”

If the stockpile is depleted further, the project will be forced to implement a 20 percent generation curtailment to preclude the possibility of reaching total coal exhaustion, which would shut the entire project down. A total plant shutdown may result in significant economic and reliability impacts to the region.

Laramie River Station is owned by the Missouri Basin Power Project, a consortium of consumer-owned electric utilities. Participants include Basin Electric Power Cooperative, Bismarck, N.D.; Tri-State Generation and Transmission Association, Denver, Colo.; Missouri River Energy Services, Sioux Falls, S.D.; the Lincoln Electric System, Lincoln, Neb.; the Heartland Consumers Power District, Madison, S.D.; and the Wyoming Municipal Power Agency, Lusk, Wyo.

Fluor Invests in NuScale

You know, it’s kind of sad that no one is willing to invest in nuclear energy anymore. Wait, what? NuScale Power celebrated the news of its company-saving $30 million investment from Fluor Corp. Thursday morning with a press conference in Washington, D.C. Fluor is a design, engineering and construction company involved with some 20 plants in the 70s and 80s, but it has not held interest in a nuclear energy company until now. Fluor, which has deep roots in the nuclear industry, is betting big on small-scale nuclear energy with its NuScale investment. "It's become a serious contender in the last decade or so," John Hopkins, [Fluor’s group president in charge of new ventures], said. And that brings us to NuScale, which had run into some dark days – maybe not as dark as, say, Solyndra, but dire enough : Earlier this year, the Securities Exchange Commission filed an action against NuScale's lead investor, The Michael Kenwood Group. The firm "misap

An Ohio School Board Is Working to Save Nuclear Plants

Ohio faces a decision soon about its two nuclear reactors, Davis-Besse and Perry, and on Wednesday, neighbors of one of those plants issued a cry for help. The reactors’ problem is that the price of electricity they sell on the high-voltage grid is depressed, mostly because of a surplus of natural gas. And the reactors do not get any revenue for the other benefits they provide. Some of those benefits are regional – emissions-free electricity, reliability with months of fuel on-site, and diversity in case of problems or price spikes with gas or coal, state and federal payroll taxes, and national economic stimulus as the plants buy fuel, supplies and services. Some of the benefits are highly localized, including employment and property taxes. One locality is already feeling the pinch: Oak Harbor on Lake Erie, home to Davis-Besse. The town has a middle school in a building that is 106 years old, and an elementary school from the 1950s, and on May 2 was scheduled to have a referendu

Wednesday Update

From NEI’s Japan micro-site: NRC, Industry Concur on Many Post-Fukushima Actions Industry/Regulatory/Political Issues • There is a “great deal of alignment” between the U.S. Nuclear Regulatory Commission and the industry on initial steps to take at America’s nuclear energy facilities in response to the nuclear accident in Japan, Charles Pardee, the chief operating officer of Exelon Generation Co., said at an agency briefing today. The briefing gave stakeholders an opportunity to discuss staff recommendations for near-term actions the agency may take at U.S. facilities. PowerPoint slides from the meeting are on the NRC website. • The International Atomic Energy Agency board has approved a plan that calls for inspectors to evaluate reactor safety at nuclear energy facilities every three years. Governments may opt out of having their country’s facilities inspected. Also approved were plans to maintain a rapid response team of experts ready to assist facility operators recoverin
