	Mine-mouth coal plants have become more common in recent years as there have been improvements in long-distance electricity transmission, making it more viable to have a power plant near a mine but perhaps further away from the point where the electricity needs to get to. In addition to reducing transportation costs, power plants and mining operations can enter these agreements to ensure the security of coal supply for the plant ~~- since~~ the plant has made specific agreements with the mine to obtain reliable amounts of ~~coal - along~~ with reduced transaction costs.<ref name="RE3">IAEE.

	Although the use of these conveniently located power plants might seem beneficial, there are also drawbacks. Many coal-rich western areas are also water-poor, and coal plants can use large amounts of water for cooling and steam production. This can potentially be a major use of water, and may pose environmental issues. ~~For more on water use in~~ coal ~~plants, click~~ [[~~water use in~~ coal-fired power ~~plants~~\|~~here~~]].

			The map below shows an example of a mine mouth operation: the Genesee coal mine and Genesee coal fired power plant. Note that the gray area has been stripped of all plant life (strip-mined) and is many kilometers across. The green area is where the mining company has replanted vegetation to [[green field]] the operation.

			[[File:Mine_mouth_coal_Genesee.png\|820px\|center\|thumb\|Figure 1. The Genesee Coal fired power plant is right next to a coal mine that has been operating for decades. Some portion of the strip-mined area has been returned to a green field. Please note that the area listed as having been part of the mine is an approximation.<ref>Image created by a member of the Energy Education team from a Google Map image found [https://www.google.com/maps/@53.3316622,-114.2856951,6879m/data=!3m1!1e3?hl=en-US here].]]
