BILLINGS, Mont. — At least 16 coal-fired power plant proposals nationwide have been scrapped in recent months and more than three dozen have been delayed as utilities face increasing pressure due to concerns over global warming and rising construction costs.

The slow pace of new plant construction reflects a dramatic change in fortune for a fuel source that just a few years ago was poised for a major resurgence. Combined, the canceled and delayed projects represent enough electricity to power approximately 20 million homes.

The U.S. Department of Energy's latest tally of pending coal plants, released last week, shows eight projects totaling 7,000 megawatts have been canceled since May. That's besides the cancellation earlier this year of eight plants in Texas totaling 6,864 megawatts. Utilities have also pushed back construction on another 32,000 megawatts worth of projects, according to the Energy Department report.

"All these reports that we were about to be inundated with coal plants, I believe this report tells a different story," said Kenneth Kern, director of analysis and planning at the department's National Energy Technology Laboratory. "What has actually happened, if you look at it closely, was much more modest than what was anticipated," he said.
