Proliferation of old-style coal plants increases despite public outcry

WYODAK, WYO. -- Utilities across the country are building dozens of old-style coal plants that will cement the industry's standing as the largest industrial source of climate-changing gases for years to come.

An Associated Press examination of Energy Department records and information provided by utilities and trade groups shows that more than 30 traditional coal plants have been built since 2008 or are under construction.

The construction wave stretches across the country and comes despite growing public wariness over the high environmental and social costs of fossil fuels, demonstrated by mine disasters in West Virginia and the gulf oil spill.

The expansion, the industry's largest in two decades, represents an acknowledgment that highly touted "clean coal" technology is still a long way from becoming a reality and underscores a renewed confidence among utilities that proposals to regulate carbon emissions will fail. The Senate last month scrapped the leading bill to curb carbon emissions following opposition from Republicans and coal-state Democrats.

"Building a coal-fired power plant today is betting that we are not going to put a serious financial cost on emitting carbon dioxide," said Severin Borenstein, director of the Energy Institute at the University of California at Berkeley. "That may be true, but unless most of the scientists are way off the mark, that's pretty bad public policy."

Following tradition

Federal officials have long struggled to balance coal's hidden costs against its more conspicuous role in providing half the nation's electricity. Hoping for a technological solution, the Obama administration devoted $3.4 billion in stimulus spending to foster clean-coal plants that can capture and store greenhouse gases. Yet new investments in traditional coal plants total at least 10 times that amount -- more than $35 billion.

Utilities say they are clinging to coal because its abundance makes it cheaper than natural gas or nuclear power and more reliable than intermittent power sources such as wind and solar. Still, the price of coal plants is rising, and consumers in some areas served by the new facilities will see their electricity bills rise by up to 30 percent. Industry representatives say those increases would be even steeper if utilities switched to more expensive fuels or were forced to adopt emission-reduction measures.

Approval of the plants has come from state and federal agencies that do not factor in emissions of carbon dioxide, considered the leading culprit behind global warming. Scientists and environmentalists have tried to stop the coal rush with some success, turning back dozens of plants through lawsuits and other legal challenges.

As a result, current construction is far more modest than projected a few years ago when 151 new plants were forecast by federal regulators. But analysts say the projects that prevailed are more than enough to ensure coal's continued dominance in the power industry for years to come.

Sixteen large plants have fired up since 2008, and 16 more are under construction, according to records examined by the AP.

Combined, they will produce an estimated 17,900 megawatts of electricity, sufficient to power up to 15.6 million homes -- about the number of homes in California and Arizona combined.

They also will generate about 125 million tons of greenhouse gases annually, according to emissions figures from utilities and the Center for Global Development. That's the equivalent of putting 22 million additional automobiles on the road.

The new plants do not capture carbon dioxide. That's despite the stimulus spending and an additional $687 million spent by the Energy Department on clean-coal programs.

Energy Department spokesman John Grasser acknowledged the new plants represent a missed chance to rein in carbon emissions. But, he said, more opportunities would arise as electricity consumption increases.

Experts say the widespread application of carbon-neutralizing technologies for coal plants remains at least 15 to 20 years away.

"This is not something that's going to happen tomorrow," Grasser said. "You have to do the required research and development and take steps along the way."

Experimental trials

Producing clean-coal power appears straightforward: Separate the carbon dioxide before it goes up the smokestack, then store it underground in geological formations.

Experimental trials have been successful, but putting the concept into commercial practice has been stymied by high costs and the difficulty of isolating carbon dioxide from other gases.

"We are pushing the envelope as far as what's possible," said Jon LaCour, manager of the 110-megawatt Wygen III coal plant, which began operating in northeastern Wyoming this spring. "We have no way of capturing carbon."

Inside the plant, a ton of coal per minute rumbles off conveyor belts from the nearby Wyodak Mine. Hulking steel pulverizers crush the fuel to the consistency of baby powder, fans blow it into a giant furnace and the coal goes up in flames that can top 1,700 degrees, producing steam to generate electricity. Wygen is more efficient than earlier plants, burning about 20 percent less coal. Yet the process has changed little since Thomas Edison built the first plant in 1882 in New York.

While dramatic advances have been made at the back end of coal plants -- where Wygen's operator, Black Hills Power, removes most of the nitrogen oxides, sulfur dioxide and other acid-rain pollutants -- efforts to curb greenhouse gases have lagged.

Black Hills spent $80 million on pollution controls for Wygen, bumping up its price tag to $247 million. Like most of the new fleet of plants, space was left at Wygen for future installation of carbon-capture equipment.

As climate change emerged as a global problem, the coal industry at times appeared on the ropes.

Environmentalists trumpeted 100 plants dropped or delayed. Regulators imposed tighter emission limits for acid-rain pollutants and reined in destructive mining practices. And the recession dampened consumer demand for power, prompting some utilities to scrap expansion plans.

But coal has not gone away.

"The reason coal burns in this country is not because anyone likes the smog. It's the cost," said Daniel Scott, a coal industry analyst with Dahlman Rose & Co. in New York.
