How drought threatens electricity producing, coal-fired power plants : NPR

RACHEL MARTIN, HOST:

Drought in the American West is forcing states to rethink how they use h2o for market. That incorporates the electricity sector and coal-fired electrical power vegetation. Julia Simon reports from Wyoming.

JULIA SIMON, BYLINE: Driving via the sagebrush west of Cheyenne, the street curves upwards.

Just coming up the hill, you just see all of this steam.

Giant smokestacks taking pictures steam up into the sky. This is the Jim Bridger Coal Plant. It powers a million-moreover homes all the way to Oregon applying very hot coal and a great deal of water for…

DAVID ESKELSEN: The cooling cycle – that probably accounts for 80% to 90% of the h2o use at the plant.

SIMON: David Eskelsen, spokesperson for plant operator Rocky Mountain Electricity, demonstrates me the reservoir, lined with rocks, some cottonwood trees, exactly where the plant sucks up 16 million gallons every single day. The plant recirculates the h2o.

ESKELSEN: But then it gets expended and evaporated. And so we require to replenish that with new drinking water from the Green River.

SIMON: But there are inquiries over how extensive there will be new drinking water. The Green River is a tributary of the rapidly shrinking Colorado River. Amidst a weather improve-fueled drought, federal officers are telling states they’ve bought to critically slash how significantly of the Colorado River they use. As for the West’s 30 coal crops, which includes Jim Bridger – their water is not locked in.

This is Wyoming Point out Engineer, Brandon Gebhart.

BRANDON GEBHART: The priority dates of the Jim Bridger – they would be likely the 1st 1 shut off unless they were able to locate a distinct resource of water.

SIMON: Joe Smyth of the Electrical power and Coverage Institute states the drought and likely h2o cuts pose a major danger to the thousands and thousands of prospects who rely on these coal vegetation for ability.

JOE SMYTH: If you do not have h2o to amazing it, you can’t operate it, appropriate? Like, it truly is not a small possibility. It is a really disruptive function.

SIMON: Previously this year, New Mexico utility PNM informed the Securities and Exchange Commission that their coal plants in the Navajo Country could be forced to slash electrical energy technology mainly because of the drought. But whilst utilities are alerting Wall Street about water shortages, for a Western coal plant like Jim Bridger, you will find uncertainty about who’s overseeing this chance on the ground.

John Burbidge is main counsel at the utility regulator at the Wyoming Public Assistance Fee. He suggests they are not tracking whether or not there’s sufficient h2o to continue to keep the electric power on.

JOHN BURBIDGE: No. I would say not. Seriously the skilled on regardless of whether you can find enough drinking water provide is heading to be the point out engineer. They are the kinds who continue to keep monitor of that.

SIMON: But State Engineer Gebhart tells NPR that though he’s satisfied to assist plant operators seem for alternate h2o sources, it truly is not his part to make certain coal crops have enough h2o to operate. Jim Bridger will not program to shut right until 2037. In the meantime, it can be taking into consideration new engineering to seize carbon emissions, in accordance to regulatory filings by the utility. The new technology would use about 35% a lot more h2o than the coal plant already makes use of. With the drought, some locals believe it is time to transfer absent from coal.

TONY VALDEZ: It truly is acquired to go. I necessarily mean, they have to go.

SIMON: Tony Valdez utilized to get the job done in coal vegetation, which includes Jim Bridger. He’s now the co-owner of a area marina on the Green River which is struggling since of the drought. The water problems of coal have him imagining about new energy.

VALDEZ: So why are we nevertheless pushing that [expletive] up in the air when we have wind we have solar we have all this things that does not impression drinking water?

SIMON: And, he suggests, they will not bring about emissions that gasoline megadroughts.
