Earlier this month, APS announced that it plans to convert its Cholla coal plant to natural gas by 2029. While APS says it will reduce emissions, the utility expects water use to be about the same.
Natural gas plants are often touted for using less water than their coal counterparts.
A report from the U.S. Energy Information Administration found that, on average, natural gas water usage was about seven times lower than coal.
But in a recent document submitted to the Arizona Corporation Commission, APS says it intends to use the same processes for steam generation and cooling from the plant’s coal days.
The utility expects the plant to use about 6,600 acre feet, or about 2.2 billion gallons of groundwater a year. In 2020, Cholla consumed almost 3 billion gallons.
