PAGE, Ariz. -- Federal regulators have issued a preliminary permit for a pumped-hydropower project using water from Lake Powell, but conservation groups say climate change could make the plan unsustainable.
The project would pump water from the lake, drain it downhill to a generator, and send the power to massive batteries for storage.
The 2,200-megawatt project would supply cities in Arizona, California and Nevada, over lines previously used by the retired Navajo Generating Station.
Gary Wockner, executive director for Save the Colorado, which opposes the plan, said falling water levels will make the Colorado River Basin an unreliable source of water.
"It's trying to build billions of dollars worth of the infrastructure in this lake and in the system that is clearly in severe decline," Wockner pointed out. "It's a strange way to try to generate electricity. There's a lot smarter, faster, easier ways to generate electricity than pumped-storage hydro."
The permit gives the developer, Daybreak Power, the go-ahead to negotiate for land-use rights and finalize plans for the project. But conservation groups say the 3-point-6-billion dollars would be better invested in solar and wind-power projects.
Jim Day, founder and CEO of Daybreak Power, claimed federal officials who reviewed the hydropower plans didn't find any major problems.
"The Bureau of Reclamation has already looked at potential impacts on the operations of Glen Canyon Dam and their preliminary look at it, they think it's perfectly compatible," Day stated.
Save the Colorado and WildEarth Guardians, both challenging the permit, said developers are ignoring climate science.
They added diminishing inflows will deplete Lake Powell of enough water to sustain the project over its projected 50-year lifespan.
Wockner believes the plant could be obsolete before it opens.
"Obviously, there's a big interest in alternative energy," Wockner acknowledged. "These things are very speculative, and this one is even more speculative because it would cost billions of dollars."
Before construction can begin on the Navajo Energy Storage Station, Daybreak Power must negotiate land and water rights with the federal Bureau of Reclamation and get permission from the Navajo Nation.
The plant is projected to go online by 2030.

As South Dakotans affected by recent record floods take stock of damages, researchers say water quality is among the concerns.
The state has been collecting damage data - but some impacts, like water contamination from livestock operations, are harder to quantify.
According to the nonprofit Food and Water Watch, coming into contact with or consuming manure-contaminated water can increase the risks of E. coli, giardia, and other waterborne illnesses. And those can lead to kidney failure, intestinal complications or cancer.
Amanda Starbuck, research director at Food and Water Watch, said public water systems are tested for these contaminants - but private, rural wells may not be.
"There's a lot of concerns about rural communities and their waters," said Starbuck, "and whether they have the ability, the financial resources, to test and to remediate any kind of contaminations that do stem from these factory farms."
Huge June rainstorms caused the Big Sioux River to swell up to 45 feet - breaking the previous record by seven feet, according to NASA, and inundating nearby farmlands.
Starbuck said South Dakota has some of the highest concentrations of confined beef, dairy and hog operations in the country.
Starbuck added that, according to a Food and Water Watch analysis, the state's factory farms produce nearly 22 billion pounds of manure each year.
"So, that's 17.5 times as much sewage as produced by the state's entire human population," said Starbuck. "So, we're talking about unsustainable amounts of livestock in these confinement operations."
She said the manure output should be of concern regardless of flooding. Still, river floodplains are expected to grow in coming years, according to a FEMA report.

New York environmentalists want the Environmental Protection Agency to re-dredge the Hudson River. This comes after the agency released its latest five-year review saying more information is needed on the dredging efforts, although progress has been made. However, other reports show the EPA's dredging efforts failed, leaving the river riddled with PCBs.
Pete Lopez, executive director for science policy and advocacy with Scenic Hudson, said the EPA's reduction targets aren't being met.
"EPA has done its best to get massive amounts out of the river, but there are massive amounts left in the river, in our opinion, that are causing PCB levels to remain persistently high and dangerous. And, EPA is not addressing it. They're kicking the can down the road," he said.
Lopez thinks the agency should investigate where high levels of PCBs are and determine how to keep fish and humans safe from them. The EPA says more annual fish data can help discern whether the cleanup is meeting the expectations of the original plan. Once the data are available, the agency will issue an addendum to the current five-year report no later than the end of 2027. A public comment period on the five-year review is being held until October, with more information available at epa.gov/hudsonriverpcbs.
The river was dredged from 2009 to 2015 to remove 30 years' worth of chemicals General Electric dumped into it. Although the EPA warns against eating fish caught in the Hudson between Troy and Hudson Falls, people still eat them, which can lead to serious health impacts. Lopez said elected officials across party lines and different state regions want the EPA to take action in cleaning up the Hudson River.
"One would think that if 22 members of Congress, a U.S. senator and leaders of the Black and Puerto Rican caucus reached out, that you would step back and think about this, and maybe want to engage with them and talk with them."
Instead, he feels actions from the EPA have been "Pro-forma correspondence," sticking to the agency's assurance that the data aren't wrong.

Wyoming's irrigation infrastructure is aging and the state gets regular requests to update it but in some cases, project benefits may not outweigh the costs.
Parts of the Bighorn Basin are some of the driest in Wyoming, according to state data. The proposed Alkali Creek Reservoir Project would provide supplemental, late-season water to 33 irrigators across 13,000 acres of land, a design in the works since 2007.
Jason Mead, director of the Wyoming Water Development Office, said a recently announced potential design change, from an open irrigation ditch to a pipeline, added about $30 million to the dam's price tag. It also decreases the ratio of benefits to costs, a calculation the office does for any water storage project it works on.
"In regards to the grant and loan, we can grant up to 100% of a project per our criteria," Mead explained. "But it's not to exceed the public benefit."
Benefits include boating and fishing in the reservoir, the short-term benefits of dam construction and the indirect benefits to local and regional economies through increased crop production. Mead noted other considerations are the life expectancy of the dam, the ability and willingness of the users to pay for it and, of course, the direct benefit to irrigators themselves, who plan to use the water mainly for alfalfa, corn, sugar beets and barley. Opponents said the dam will disrupt natural watershed functions.
Dagny Signorelli, Wyoming director for the Western Watersheds Project, said the dam could reduce spring flows in Paint Rock Creek by 33%, in Medicine Lodge Creek by 16% and in Alkali Creek up to 100%.
"In general, dams disrupt natural river ecosystems by altering their flow patterns and reducing the frequency and intensity of natural flooding events," Signorell pointed out.
Signorelli added it could alter habitat for wildlife both upstream and downstream, with special concerns for trout, pronghorn, elk, mule deer and raptors. Plus, according to permit objections submitted by Western Watersheds Project in 2018, greater sage grouse use five breeding grounds within a four-mile radius of the project.
