As of July 7, 2011, utility companies will shut down and retire aging coal-fired power plants following the Environmental Protection Agency's (EPA) announcement of the Cross-State Air Pollution Rule (CSAP).[16] The extent of shutdowns and reduction in utilization will depend on factors such as future price of natural gas and cost of installation of pollution control equipment; however, as of 2013, the future of coal-fired power plants in the United States did not appear promising.[17][18] Recent estimates gauge that an additional 40 gigawatts (GW) of coal-fired capacity will retire by 2020 (in addition to the nearly 20GW that have retired as of 2014). This is driven most strongly by inexpensive natural gas competing with coal, and EPA’s Mercury and Air Toxics Standards (MATS), which require significant reductions in emissions of mercury, acid gases, and toxic metals, scheduled to take effect in April 2015.[19] Over 13 GW of coal power plants built between 1950-70 were retired in 2015, averaging 133 MW per plant.[20] In Texas, the price drop of natural gas has reduced the capacity factor in 7 of the state's coal plants (max. output 8 GW), and they contribute about a quarter of the state's electricity.[21]
