Big Brown Power Plant was a 1.15-gigawatt (1,150 MW) coal power plant located northeast of Fairfield near Fairfield Lake State Park in Freestone County, Texas. It was operated by Vistra Corp's subsidiary, Luminant. The plant operated from 1971 to 2018.

History

Big Brown was constructed by Texas Utilities (now known as Luminant) and went into operation in 1971. [2] It has two units. [3] Big Brown Creek was impounded to form the plant's cooling source. The dam was completed in 1969 creating Fairfield Lake. [4] The power plant used lignite from the nearby Turlington Mine and later supplemented with coal from Peabody Energy's Rawhide Mine in the Powder River Basin of Wyoming. [3] [5] To improve the overall fuel mix and to reduce reliance on the nearby Turlington Mine whose lignite production was decreasing, coal from the Powder River Basin was blended into the fuel beginning in 2000. [6] LO-NOx burners were installed in both boilers in 2001 to curtail nitrogen oxide (NOx) emissions. [6] NOx emissions were reduced again in 2008 with selective non-catalytic reduction (SNCR) systems being retrofitted by Fluor to Big Brown's units. [7] [8] The plant was temporarily idled in 2011 in order to overhaul its boilers. [9] This was to fulfill the United States Environmental Protection Agency's (EPA) Cross-State Air Pollution Rule to reduce its sulfur dioxide (SO
2
) emissions. [9] With the plant idling, Luminant halted lignite extraction at the nearby Turlington Mine until the plant resumed electricity generation. [10] Claiming lignite reserves were nearly exhausted at Turlington Mine, Luminant made plans in 2014 to close the mine by 2018 and rely solely on coal from the Powder River Basin. [11]

Closure

It was announced on October 13, 2017 that Luminant was to either shut down or sell to another concern Big Brown in early-2018 due to economic factors such as low natural gas prices and growth in renewable energy. [12] The following month, Electric Reliability Council of Texas (ERCOT) approved of the shut down. [13] ERCOT found the two-unit Big Brown plant was "not required to support ERCOT transmission system reliability", and authorized its closure by February 12, 2018. [14]

Lignite Soft, brown, combustible, sedimentary rock

Lignite, often referred to as brown coal, is a soft, brown, combustible, sedimentary rock formed from naturally compressed peat. It has a carbon content around 25–35%, and is considered the lowest rank of coal due to its relatively low heat content. When removed from the ground, it contains a very high amount of moisture which partially explains its low carbon content. Lignite is mined all around the world and is used almost exclusively as a fuel for steam-electric power generation.

From 1998 to 2007, the company was known as TXU Corporation until its $45 billion leveraged buyout by Kohlberg Kravis Roberts, TPG Capital and Goldman Sachs Capital Partners. That purchase was the largest leveraged buyout in history. As of 2019, TXU Energy is a subsidiary of publicly traded Vistra Energy.

William H. Zimmer Power Station

The William H. Zimmer Power Station, located near Moscow, Ohio, is a 1.35-gigawatt coal power plant. Planned by Cincinnati Gas and Electric (CG&E), with Columbus & Southern Ohio Electric and Dayton Power & Light (DP&L) as its partners, it was originally intended to be a nuclear power plant. Although once estimated to be 97% complete, poor construction and quality assurance (QA) led to the plant being converted to coal-fired generation. The plant began operations in 1991. Today, the plant is owned and operated by Vistra Corp.

Centralia Power Plant

Centralia Big Hanaford power plant is a major coal-fired power plant supplemented with newer natural-gas-fired units. It is located east of Centralia, Washington, United States in Lewis County. As of 2006, it is the only commercial coal-fired power plant in the State of Washington. A bill signed in 2011 by governor Christine Gregoire, the TransAlta Energy Transition Bill, resulted in one coal boiler being shut down in 2020 and the other by the end of 2025.

Refined coal is the product of the coal-upgrading technology that removes moisture and certain pollutants from lower-rank coals such as sub-bituminous and lignite (brown) coals, raising their calorific values. Coal refining or upgrading technologies are typically pre-combustion treatments and/or processes that alter the characteristics of a coal before it is burned. The goals of pre-combustion coal-upgrading technologies are to increase efficiency and reduce emissions when coal is burned. Depending on the situation, pre-combustion technology can be used in place of or as a supplement to post-combustion technologies to control emissions from coal-fueled boilers. A primary benefit of refined coal is the capacity to reduce the net volume of carbon emissions that is currently emitted from power generators and would reduce the amount of emissions that is proposed to be managed via emerging carbon sequestration methodologies. Refined coal technologies have primarily been developed in the United States. Several similar technologies have been researched, developed and tested in Victoria, Australia, including the Densified coal technology developed to alter the chemical bonds of brown coal to create a product that is cleaner, stable, exportable and of sufficiently high calorific value to be a black coal equivalent.

Rawhide Mine Coal mine in Gillette, Wyoming, United States

The Rawhide Mine is a coal mine located 10 miles (16.1 km) north of Gillette, Wyoming in the United States in the coal-rich Powder River Basin. The mine is an open pit mine that utilizes a combination of cast blast/dozer push and truck/shovel mining methods to strip an average of 165 feet (50.3m) of overburden off of approximately 105 (32.0m) feet of coal. Rawhide produces a low-sulfur, sub-bituminous coal from the Roland and Smith seams. This coal is used for domestic energy generation and shipped to customers via railroad. The mine is currently owned and operated by Peabody Energy.
