Regional Grid Operator OKs W.Va. Power Plant Closure

The nation’s largest electric grid operator said a massive coal-fired power plant near Parkersburg can close next January without affecting the region’s power system.

PJM Interconnection operates the grid covering 65 million people from Illinois to Washington, D.C. It has found closing the 1,300-megawatt Pleasants Power Station would not damage electricity transmission systems or cause power outages.

Ohio-based utility FirstEnergy announced last month that it plans to shut down two coal-fired units in Willow Island next year. The Pleasants Power Station opened in 1979 and produces enough electricity to power about 1.3 million homes, but it is struggling to stay competitive against low natural gas prices and newer coal-fired plants.

Ray Dotter, manager of strategic and stakeholder communications for PJM, said in an email that the grid operator found no reliability issues associated with the projected Jan. 1 closure of the coal-fired plant.

In its review, he said PJM focused on what, if any, effects shuttering the plant would have on the transmission system. For example, PJM looking at whether taking the plant offline could cause transmission lines to be overloaded, especially on days when demand for power is high.

Earlier this year, the Federal Energy Regulatory Commission denied a request from two FirstEnergy subsidiaries – Mon Power and Potomac Edison – to buy the plant. The West Virginia Public Service Commission had approved the proposed sale, but set limits on the amount of costs that could be passed down to customers. The plant employs about 190 people.

A spokeswoman for FirstEnergy said the company intends to operate the plant normally until the end of 2018 unless a buyer is found.

Study Finds Hormone-Disrupting Chemicals Near Fracking Wells

Dozens of chemicals that can affect the fertility of humans and animals are being found in the air near unconventional oil and gas development, according to a new study.

 

More than 200 chemicals have been found near unconventionally drilled sites, most-commonly fracked wells, according to a paper published today in the journal Environmental Health.

Carol Kwiatkowski, executive director of a nonprofit called the Endocrine Disruption Exchange, said that of those chemicals, 34 are known to be endocrine disruptors, or chemicals that interfere with hormone systems in mammals.

“Well-known hazardous air pollutants are being found near fracking sites and may be contributing to health outcomes that are being experienced by people living near fracking sites,” said Kwiatkowski, a co-author of the study. “The endocrine disrupting chemicals that are found at these sites may be contributing to health outcomes that won’t be realized for decades.”

Researchers reviewed more than 4,000 peer-reviewed papers. In total, they found 48 air sampling studies were conducted between 2003 and 2016. Texas’ Barnett Shale formation was studied the most. The Marcellus Shale formation in the Ohio Valley, was the fourth-most-studied area.

Chemicals known to cause cancer, and heavy metals such as mercury, were also found near oil and gas development. 

Researchers said more information is needed to know what the long-term health impacts of these chemicals are. An estimated 17.6 million Americans live near unconventional oil and gas wells.

For this paper, the researchers did not do any original experiments, rather they looked only at the already-published science. The study also does not draw a direct link between hormone-disrupting chemicals and oil and gas development. Instead, it shows studies have found these chemicals are often found near oil and gas development.
