The article quotes the spokesperson of a company heavy in coal plants saying, "We have no current plans to build any new coal-fueled power plants both because we don't need additional generation, and it would be difficult to make an economic case for coal with today's low natural-gas prices".
This is the lock on the door that will prevent future consideration if the price of natural gas rises. Probably more important is a rule change enacted earlier this year on "the social cost of carbon".
Obama Quietly Raises 'Carbon Price' as Costs to Climate Increase

Buried in a little-noticed rule on microwave ovens is a change in the U.S. governments accounting for carbon emissions that could have wide-ranging implications for everything from power plants to the Keystone XL pipeline.
The increase of the so-called social cost of carbon, to $38 a metric ton in 2015 from $23.80, adjusts the calculation the government uses to weigh costs and benefits of proposed regulations. The figure is meant to approximate losses from global warming such as flood damage and diminished crops.
With the change, government actions that lead to cuts in emissions -- anything from new mileage standards to clean-energy loans -- will appear more valuable in its cost-benefit analyses. On the flip side, environmentalists urge that it be used to judge projects that could lead to more carbon pollution, such as TransCanada Corp. (TRP)s Keystone pipeline or coal-mining by companies such as Peabody Energy Corp. (BTU) on public lands, which would be viewed as more costly.
As we learn that climate damage is worse and worse, there is no direction they could go but up, Laurie Johnson, chief economist for climate at the Natural Resources Defense Council, said in an interview. Johnson says the administration should go further; she estimates the carbon cost could be as much as $266 a ton....

It's a start but we really need to get control of Congress back.
