The owners of the Navajo Generating Station coal-fired power plant near Page will vote Monday on whether to shut the plant down this year or try to keep it running at least through 2019, officials said Tuesday.
The plant has faced a variety of environmental challenges through the years, but now is jeopardized by the fact that natural-gas-fired power plants generate electricity at a lower cost. The owners, led by Salt River Project, are considering a shutdown, rather than extending the lease beyond its expiration in 2019.
The owners — SRP, the U.S. Bureau of Reclamation, Arizona Public Service Co., Tucson Electric Power Co. and NV Energy — will have a 1 p.m. conference call Monday to vote on the plant's future.
"It’s the hope of the owners that we can operate the plant through 2019," SRP spokesman Scott Harelson said.
"This is an economic circumstance, not a regulatory question," Harelson said.
The Bureau of Reclamation is not prepared to shut the plant down. It uses its share of the power to run pumps on the Central Arizona Project canal that brings Colorado River water to Phoenix, Tucson and tribes in southern Arizona.
"The Department's preferred path is to bring parties together to ensure operations at least through the current lease term, which runs through 2019," Bureau of Reclamation Deputy Commissioner David Palumbo said via email. "We are equally committed to exploring ways in which the plant could operate economically post-2019."

He noted that the plant is important economically to the region, especially for the Navajo and Hopi tribes and those that rely on CAP water.
"Before discussing the possibility of a permanent shutdown, we would like to see if we can find a path forward that meets the needs of the multiple NGS stakeholders," he said.
If the plant owners are not going to keep running the plant through 2019 and don't negotiate a lease extension, they would need to start tearing it down for decommissioning by the end of this year.
Harelson said the owners are negotiating with the tribe to start decommissioning after the lease expires.
LoRenzo Bates, speaker for the Navajo Nation Council, said the tribe is discussing what will be required for a shutdown and allowing decommissioning to take place after the current lease expires.
“As far as the meeting on Monday, I would ask SRP and all the owners to assess the impact it will bring to the Navajo and Hopi,” Bates said Tuesday. “We should all sit down at the table and address the matter and see if there are alternatives.”
Harelson said he could not discuss any possible concessions that could be offered the Navajo and Hopi tribes to make up for the impact the closure will have on their economies. About 500 mostly Native American people work at the power plant and another 326 at the Kayenta Mine 80 miles away that supplies coal.
Both the Navajo and Hopi governments rely heavily on the royalties from the coal mine, which straddles the neighboring reservations.
Harelson also could not say whether any solar or wind projects might be proposed to make up for some of the job losses associated with a closure.
"We are having discussions with the (Navajo) Nation with respect to the plant's future and their energy future," Harelson said.
It seems unlikely the plant will operate beyond 2030, when it will require additional environmental controls to comply with the Environmental Protection Agency. Under a deal struck with the EPA, the plant will close one of its three generators in 2019, representing the portion of the plant recently sold by a California utility and the Nevada utility that is following suit. The second part of that agreement with the EPA is to add additional controls on the plant in 2030, which Harelson said is another decision the owners would need to make.
Meanwhile, utility regulator Andy Tobin on Tuesday asked fellow Arizona Corporation Commissioner members to require TEP to provide an analysis regarding whether closing the plant is prudent and whether TEP has considered purchasing SRP's share of the plant.
The five regulators on the Arizona Corporation Commission do not regulate SRP, a public utility, but they regulate APS and TEP. Tobin said he is concerned about the "obvious" economic impacts of closing the plant and also utilities' over-reliance on natural gas, and wants to keep the coal plant open if possible.
His suggestion for TEP to take over a larger portion of the plant was filed as an amendment to TEP's rate case.
