Austin, Texas - Today, Luminant Energy announced closures of its two-unit Sandow Power Plant in Milam County, Texas, and its two-unit Big Brown Power Plant in Freestone County, Texas. This announcement comes days after Luminant Energy’s first announcement to retire its Monticello three-unit coal-burning power plant. Together, these three Luminant coal plants emitted a total of 166 million pounds of sulfur dioxide, 24 million pounds of nitrogen oxide, and 21 million tons of carbon dioxide pollution in 2016.

Public health analyses have shown that pollution from Big Brown and Sandow cause or contribute to more than 6,400 asthma attacks, 187 premature deaths, and more than 151,000 lost or limited work days every year, resulting in more than $1.6 billion in public health and lost productivity costs annually. Closure of these two additional plants will result in significant air and water quality benefits for Texas communities in the Dallas Fort-Worth, Austin, Pflugerville, Round Rock and Taylor regions, as well as communities across the central United States.  

“Air quality in North Texas has been bad for decades. This news is a relief for the thousands of families in Dallas who are struggling with asthma and other respiratory ailments caused by smog from these coal fired power plants,” said Cherelle Blazer, a long time Dallas area organizer. “The retirement of these super polluters is a victory for all of Texas, the residents, volunteers, local experts and organizations who tirelessly give their time and energy to tell TCEQ, EPA and countless public officials that we need protection from pollution levels that violate the federal clean air standard.”


A coalition of environmental groups--Sierra Club, Earthjustice, Environmental Integrity Project, the Sustainable Energy and Economic Development Coalition, National Parks Conservation Association, Breath is Lyfe, and Public Citizen--has worked in Texas to cut dangerous coal pollution from plants in the state. As a result of these groups’ advocacy, Big Brown was designated as violating health-based air quality safeguards for dangerous sulfur dioxide. Both power plants are currently the subject of several federal Clean Air Act (CAA) lawsuits. Sierra Club, Environmental Integrity Project, and Earthjustice have worked together  in a variety of matters seeking to enforce the Clean Air Act at the Big Brown, Sandow, and Monticello coal plants. These plants also  pollute air quality in 17 national parks and wilderness areas across the central United States, including Big Bend and Guadalupe Mountains National Parks.

"Today's announcement is a victory for Texas's national parks and the millions of visitors they welcome every year. The closure of these plants will mean less pollution harming our climate and degrading the air quality in parks like Big Bend and Guadalupe Mountain, both of which are major drivers for local economies,” Stephanie Kodish, Senior Director & Counsel of National Parks Conservation Association’s Clean Air Program. “Clean air for the region's national parks remains far off so long as Texas continues to refuse taking steps to clean up all its coal-fired power plants and other industrial sources. Not until the state and EPA steps up and takes meaningful action to cut remaining plants' pollution will we achieve clean air for our national parks and the people that cherish them."  

Taken together, Luminant’s three retiring plants would lower sulfur dioxide emissions from Texas power plants by more than a third, and nitrogen oxide emissions and global-warming emissions from power plants by nearly 10 percent within the State of Texas. In addition, thousands of pounds of dangerous toxic emissions like mercury would also be removed from the air, water and land.


This marks the 13th and 14th coal plants to announce retirement in 2017. This underscores that the country is moving away from coal faster since Trump was inaugurated than during the last six years of the Obama Administration, and builds on the U.S. progress to cut more carbon pollution than any other country in the world.

Texas in particular is rapidly transitioning away from obsolete coal plants like the Luminant fleet because of their virtually uncontrolled pollution and because of the rise of low-cost renewable energy. These coal-fired power plants are among the largest polluters in the country and are increasingly unable to compete against plentiful and clean renewable energy. Currently solar and wind power are providing roughly 20 percent of all power within ERCOT, and more than 20,000 MW of wind and 1,000 MW of solar have already been installed in Texas. In addition, more than 50,000 MW of future wind and solar projects are currently being assessed in the ERCOT market according the latest Generation Interconnection Status Report.

"The retirement of the coal-fired Big Brown and Sandow units will mean cleaner air for millions of Texans," said Shannon Fisk, Managing Attorney at Earthjustice. "Closing these old, polluting units speeds the transition to a clean energy future that enables economic growth while protecting public health.  It is critical that we also take steps to ensure a just transition for the employees and communities affected by these closures."

The Sierra Club is committed to building a future beyond coal in Texas that supports workers and communities historically dependent on coal while improving air quality and protecting public health. For decades, big coal has worked to pit workers against communities concerned about the air they breathe and water they drink. The Sierra Club is part of a growing movement of Americans demanding both family-supporting jobs and clean air and water, and is organizing across the country to ensure that coal companies like Luminant and Peabody don't abandon coal-dependent communities and workers like they've abandoned their concern for clean air and water.
