From Global Energy Monitor

Monticello Steam Electric Station was a coal-fired power station owned and operated by Luminant near Mount Pleasant, Texas.

The power station was retired in January 2018.[1][2]

In October 2017 Luminant announced all three units of the power station would be retired in January of 2018.[3] The shutdown decision followed a year-long review of the plant's economic viability, after which the company decided the plant was a "money loser." In recent years, Luminant started operating Monticello only at times when demand and electricity prices were higher, mostly summer and winter peaks. Luminant has found it increasingly difficult to compete in the Texas market against cheaper natural gas and wind power.[1]

Emissions Data

  • 2006 CO2 Emissions: 18,268,348 tons
  • 2006 SO2 Emissions: 77,538 tons
  • 2006 SO2 Emissions per MWh:
  • 2006 NOx Emissions: 14,382 tons
  • 2005 Mercury Emissions: 1,595 lb.


It was announced on September 12, 2011 that Monticello Unit 1 and 2 would be idled in January 2012 if Energy Future Holdings, owner of Luminant, failed in its legal challenge to pending federal air pollution rules known as the Clean Air Transport Rule. It was also reported that the company would close both its Thermo Mine and Winfield South Mine at the same time.[4]

The Clean Air Transport Rule rule was initially blocked by litigation. Later, Texas was removed from the list of states that must comply with that rule.[1]

Citizen Action

Sierra Club calls for closure of three coal plants in Texas

On March 18, 2011 the Sierra Club released a report stating that three of Luminant's coal plants in East Texas should be shut down because the facilities do not meet Clean Air Act standards and need $3.6 billion in upgrades in order to comply with federal regulations.

The three plants targeted were Big Brown, Monticello Steam Station and the Martin Lake Steam Station plant. The Sierra Club expressed concern about "the major threats to air and water pollution that citizens in the Barnett Shale [in North Texas] are dealing with firsthand."[5][6]

The study recommended:

"[R]eplacement of three coal fired power plants built in the 1970’s (Big Brown, Monticello and Martin Lake) is a financial and environmental necessity. The plants, currently owned by Energy Future Holding/Luminant and serving North Texas are financially mismanaged, cannot compete profitably in the current market, require pollution control upgrades that are unaffordable and have suffered deep losses in market value. The financial outlook for the company and the plants going forward show very little upside. A broad look at the national and Texas energy market suggest planning tools and resources exist to ensure a smooth transition to a more financially stable and reliable supply of electricity."

Death and disease attributable to fine particle pollution from Monticello Steam Station

In 2010, Abt Associates issued a study commissioned by the Clean Air Task Force, a nonprofit research and advocacy organization, quantifying the deaths and other health effects attributable to fine particle pollution from coal-fired power plants.[7] Fine particle pollution consists of a complex mixture of soot, heavy metals, sulfur dioxide, and nitrogen oxides. Among these particles, the most dangerous are those less than 2.5 microns in diameter, which are so tiny that they can evade the lung's natural defenses, enter the bloodstream, and be transported to vital organs. Impacts are especially severe among the elderly, children, and those with respiratory disease. The study found that over 13,000 deaths and tens of thousands of cases of chronic bronchitis, acute bronchitis, asthma, congestive heart failure, acute myocardial infarction, dysrhythmia, ischemic heart disease, chronic lung disease, and pneumonia each year are attributable to fine particle pollution from U.S. coal plant emissions. These deaths and illnesses are major examples of coal's external costs, i.e. uncompensated harms inflicted upon the public at large. Low-income and minority populations are disproportionately impacted as well, due to the tendency of companies to avoid locating power plants upwind of affluent communities. To monetize the health impact of fine particle pollution from each coal plant, Abt assigned a value of $7,300,000 to each 2010 mortality, based on a range of government and private studies. Valuations of illnesses ranged from $52 for an asthma episode to $440,000 for a case of chronic bronchitis.[8]

Type of Impact Annual Incidence Valuation
Deaths 50 $370,000,000
Heart attacks 75 $8,200,000
Asthma attacks 860 $45,000
Hospital admissions 37 $840,000
Chronic bronchitis 31 $14,000,000
Asthma ER visits 54 $20,000

Monticello sixth highest in 2009 mercury emissions

The 2011 Environmental Defense Fund report, "Mercury Alert: Cleaning up Coal Plants for Healthier Lives" found that 25 plants alone are responsible for nearly a third of all mercury emissions in the power sector, while providing only eight percent of U.S. electricity. The findings are based on 2009 U.S. Department of Energy data. The plant with the sixth highest mercury emissions was Monticello Steam Station, releasing 1,063 lbs in 2009.[9]
