The Powder River Basin (PRB) is a region in southeast Montana and northeast Wyoming about 120 miles east to west and 200 miles north to south known for its coal deposits. It is the single largest source of coal mined in the United States and contains one of the largest deposits of coal in the world. Most of the active coal mining in the Powder River Basin actually takes place in drainages of the Cheyenne River. Because of the Powder River Basin, Wyoming has been the top coal-producing state in the United States since 1988.
In 2007, the Powder River Basin alone produced 436 million short tons (396 million tonnes) of coal, more than twice the production of second-place West Virginia, and more than the entire Appalachian region. Overall, the Powder River Basin accounts for about 37 percent of U.S. coal production. The Black Thunder Mine is the most productive coal mine in the United States; in 2006 this single mine produced 84 million metric tons of coal, more than any state except Wyoming, West Virginia, and Kentucky.
The majority of the coal mined in the PRB is part of the Fort Union Formation. Because of its low sulfur and fly ash content, this coal is exported outside the region and supplies of the coal in the region makes it very desirable. Coal supplies about half of the United States electricity supplies, with the PRB mines supplying around 40% of the coal that fuels those stations, mainly to the east of the Rocky Mountains.
Virtually all the coal mined in the Powder River Basin (431 million tons out of the 436 million tons mined in the entire basin in 2006) comes from the Gillette field. In 2008 the U.S. Geological Survey released a detailed assessment of the coal resource in the Gillette field. USGS concluded that the portion of the recoverable coal that can be mined, processed, and marketed at a profit, based on conditions in 2007, including $10.47 per ton and assuming an 8 percent rate of return, is 10.1 billion short tons for the six coal beds evaluated. This is about half the estimate arrived at by a 2002 study of the same field, which arrived at an economically recoverable resource of 23 billion short tons. However, if the price of coal is assumed to be $14.00 per ton, matching the sales price of coal for the Gillette coalfield as of March 2008, the reserve would be 18.5 billion short tons, assuming no increase from 2007 operating costs. If cost per ton rose to $60, the estimated reserve would rise to 77 billion short tons.

The Pace Coal Project was originally tested by Mobil Oil in 1979. At that time, 45 samples were taken, which showed that the coal was high volatility bituminous, a higher grade of coal than normal in the Powder River Basin. In April 2010, American Power Corp. acquired the land associated with the project. It is believed that the mine could hold 410 million tons of coal.
The Buckskin Mine Hay Creek II proposed mine is an extension of the existing Buckskin Mine.
In February 2010, Management Energy Inc., a California coal startup, amassed leases on more than 10 square miles of land to build new coal mines in south-central Montana, near Red Lodge, in partnership with Tennessee coal entrepreneur John Baugues Jr..
In March 2010 Arch Coal made a successful bid of $85.8 million for the right to mine about 8,300 acres of state-owned minerals in the Otter Creek Tracts in southeastern Montana. The company said the land is a strategic platform for future growth in the Northern Powder River Basin. The company controls about 1.5 billion tons of coal reserves in Montana’s Otter Creek area.
The state of Montana Land Board has been looking to lease 616 million tons of coal reserves known as Otter Creek, which it received from the Federal Government at the beginning of the decade. The State Board of Land Commissioners made the initial decision on December 21, 2009. Montana Governor Brian Schweitzer, a proponent of coal development, sits on the board along with other Montana officials.

The Powder River Basin is expected to face severe rail congestion until at least late 2014 according to the U.S. Energy Information Administration. Despite the frigid winter and an increased demand for coal to restock pile utilities, the delays from winter weather have created a backlog of coal shipments. Additionally, a shorter harvest season and the boom in domestic oil production created the increased need for rail cars. All of these factors have cause severe delays in rail deliveries out of the Powder River Basin.
Mines like Arch Coal are seeing this first hand such as at the Black Thunder mine where the company will be trying to fulfill their orders throughout the remainder of 2014.

As Washington state governor Jay Inslee recently stated that he looks to wean Washington state utilities off of coal completely, China publicly released a plan last week to speed up their solar power development. This is in response to the devastating pollution caused as a result of coal consumption in China and the growing public pressure to switch to more clean burning power.
In combination, these decisions could have a major long-term impact on the coal companies of the Powder River Basin whom rely heavily on coal exports to the Chinese market as well as utilities in the nearby Northwest.

Union workers are facing dire prospects in maintaining their unions in the Powder River Basin coal-mines. Of the 16 coal-mines operating in the Powder River Basin, only 3 are still unionized. Additionally all 3 of these remaining unions primarily work on reclaiming mined land, rather than on high volume producing coal mines.
This shrinking of unionization in the Powder River coal beds highlights the goal of the coal companies to keep the union out of the highest grossing and most productive mines.

Washington state recently proposed to curb carbon pollution by eliminating imports of coal-fired power. Though coal only accounts for 13 percent of Washington’s electricity, coal accounts for almost 80 percent of the Washington utilities’ emissions of carbon dioxide.
In response, U.S. Representative Steve Daines has directly addressed Washington governor Jay Inslee to override this proposal. Daines stated that limiting imports of coal would significantly harm Montana jobs and the economy of the entire state.

At the close of the first quarter of 2014, the four largest coal companies working in the Powder River Basin of Wyoming all posted losses. The reasons being attributed for these losses are the bad weather and rail interruptions that have slowed down the shipments of coal out of Wyoming.
Nevertheless, coal executives with Alpha Natural Resources, Arch Coal, Cloud Peak Energy and Peabody are all optimistic that next year will see significant improvement in contrast to the losses incurred during this first quarter of 2014.

Chinese delegates recently visited the Cordero Rojo mine in Wyoming’s Powder River Basin as part of a three-day tour of Wyoming to increase U.S., Chinese relations. The visit highlights China’s demand for American coal and the massive growth of the energy sector in China.
China is the biggest coal customer in the world and uses four times the amount of coal annually as the United States at over 4 billion tons of coal a year. The government affairs manager for Cloud Peak Energy, Jason Begger emphasized the biggest challenge in getting Wyoming coal into the hands of the Chinese is the challenges of exporting the coal out of the northwest. This article underlines the point that the supply of Wyoming coal is contributing to the vast economic growth of China’s industrialization.

After Montana and Wyoming endured one of the coldest winters in collective memory, the coal piles needed to fuel power plants has waned as coal train deliveries have struggled to provide reliable services. The Powder River Basin is home to the largest coalmines in the US and supplies huge amounts of coal throughout the US.
These shortages in coal deliveries has caused increased losses for utilities and threatens to be a continuing issue come summer peak season. The explanations for the delays in coal deliveries by the railroad have ranged from cold weather conditions to increased traffic as a result of the explosion in natural gas in the Bakken in combination with vast deposits mined in the Powder River Basin.

The Powder River Basin in 2013 listed the top nine coal producing mines in the United States. However, the amount of mines in the Powder River Basin situated in the top twenty five highest producing mines shrinked as compared to twenty years ago.
The decline in the amount of Powder River Basin mines being in the top twenty-five is the result of large mining projects taking hold in New Mexico, Texas, Indiana and Ohio. Nevertheless, the scale of coal production in the Powder River Basin’s Black Thunder mine and the North Antelope Rochelle mine are the largest producing coalmines with growths as high as 400% since 1994.
