Parish Generating Station
Washington A. Parish Electric Generating Station is a coal-fired power station owned and operated by NRG Energy near Thompsons, Texas.
It is also the site of the Petra Nova Carbon Capture and Storage (CCS) project.

The power station is at 2500 Y.U. Jones Rd., Thompsons, Texas.
The project entails a 240-megawatt slipstream of exhaust flue gas flowing into a capture system that will filter out 90 percent of the carbon dioxide, along with particulates, sulfur oxides and nitrogen oxides. The captured carbon dioxide will be pumped 82 miles to the West Ranch oil field in Jackson County, Texas. Drillers estimate that the field holds 60 million barrels that could be recovered with the captured carbon.
DOE selects NRG Energy for carbon capture project in Texas
In September 2009, NRG announced that it was applying for funding from the Department of Energy to subsidize the cost of installing carbon capture and storage equipment at Parish. The company would not disclose the cost of the equipment. The demonstration project would capture about 90 percent of the carbon dioxide emissions from 60 megawatts of power generation.
In March 2010 it was announced that the U.S. Department of Energy (DOE) selected NRG to receive US$154 million, which includes funding from the American Recovery and Reinvestment Act, to construct a "post-combustion carbon capture demonstration unit" outside of Houston at the company's Parish Generating Station. The project is scheduled to go online in 2013.
Ownership and funding
NRG Energy and JX Nippon Oil & Gas Exploration Corp., Japan’s largest oil producer, are running the Petra Nova project as a 50-50 joint venture under the umbrella of Petra Nova Parish Holdings LLC. The US$1.04 billion project received US$300 million each from NRG and JX Nippon. NRG also received US$167 million from the U.S. Department of Energy’s Clean Coal Power Initiative, plus another US$23 million from DOE under Section 313 of the Consolidated Appropriations Act of 2016 for the carbon capture system. The Japan Bank for International Cooperation and Mizuho Bank Ltd. are also providing loans totaling US$250 million.
NRG said it will not fund more CCS
In October 2015 NRG Energy said that while it will complete the construction of the Petra Nova Carbon Capture and Storage (CCS) project at the Parish coal plant in Texas, it will not invest in further projects. NRG Chief Executive David Crane acknowledges that CCS for enhanced oil recovery was attractive when the oil price was between US$75 to $100 a barrel but, with oil selling for US$45 a barrel, it is no longer viable.
CCS project goes online in 2017

Death and disease attributable to fine particle pollution from Parish Generating 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. 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.

Parish ranked 6th in terms of largest carbon dioxide emissions
According to a 2009 report by Environment America, "America's Biggest Polluters," the Parish Generating Station is the sixth dirtiest plant in the nation, releasing 20.9 million tons of carbon dioxide in 2007. Ranking is based upon Environmental Protection Agency data.
