During the Arizona Corporation Commission’s annual Summer Preparedness Workshop, Chair Kevin Thompson and Vice Chair Nick Myers essentially echoed the talking points of Arizona Public Service Company (APS) and Tucson Electric Power (TEP). Both utility companies implicitly refused to reactivate the Cholla and Springerville Coal-Fired Power Plants in defiance of President Trump’s Executive Order earlier this month. Thompson claimed doing so would “jeopardize the grid and burden ratepayers with millions of dollars in short-sighted costs.”
In early April, President Donald Trump issued an Executive Order (EO) using emergency authority to keep APS’ Cholla Power Plant in operation. In a statement issued with the EO, Trump said, “I am instructing Secretary Wright to save the Cholla coal plant in Arizona, which has been slated for destruction. We’re going to keep those coal miners on the job. We’re going to have that plant opening and burning beautiful, clean coal in a very short period of time.”
According to an emailed release from the ACC, the APS representative at the workshop “stated that the process that culminated in closing the plant began ten years ago because of new regulations from the U.S. Environmental Protection Agency (EPA) making the operation of the plant uneconomic for their customers.” The utility added, per the ACC that “because of the ongoing EPA regulations requiring new equipment for pollution control and significant deferred capital and maintenance investments that would have to be made, the re-opening and continued operation of the Cholla plant would come at a significantly high cost for customers.”
APS reiterated that it intends to preserve the infrastructure of the power plant and offered that it could be used as a potential site for nuclear or natural gas power later, implicitly refusing to bring the coal-fired plant back online.
Similarly, TEP confirmed that it still intends to move forward with the scheduled retirement of Units 1 and 2 at the coal-fired Springerville Generating Station after the summer of 2027 and after the summer of 2032. The utility is also exploring the possibility of repurposing the power station for an alternative fuel source.
Vice Chair Myers commented, “We’re all aware of the detrimental loss of electric capacity with the closure of Arizona coal plants, and in part because of ongoing EPA regulations. It is a day late and a dollar short when it comes to re-opening the Cholla plant. Trying to re-open Cholla at this point would result in significantly higher rates for customers,” repeating the APS talking point.
He added, “The utilities have already been planning for this retirement and replacement costs are already being born by the utility customers. Re-opening Cholla would also require significant capital and maintenance investments that have been deferred. Further, the EPA requirements that made the continued operation of Cholla not cost-effective are still in effect. The damage has already been done. Arizona utilities are prepared for that and already planning to repurpose those plants for future generation, such as nuclear or natural gas-fired power.”
“Bringing the Cholla plant into compliance with Obama era EPA requirements will require the installation of costly scrubbers on the coal-fired units that would cost ratepayers hundreds of millions of dollars,” said Chair Kevin Thompson.
Thompson added a subtle critique of the President’s movement to reactivate the Cholla Generating Station saying, “The Commission must hold utilities accountable and ensure that we have reliable and dispatchable generation to meet the load demands of the future. We also have to make sure we accomplish that goal in a manner that doesn’t jeopardize the grid and burden ratepayers with millions of dollars in short-sighted costs that fail to meaningfully address our long-term energy needs.”
