The Sierra Club has filed suit against Salt River Project over records relating to a proposed expansion of a natural gas powered plant near Coolidge.
Conservationists and residents who live near the plant have opposed the expansion since it was proposed in August 2021.
The Sierra Club is pushing the utility to move faster on climate change and says that it requested documents under public records law to learn about the power generation and planning process.
But SRP said that public records laws did not apply to the utility.
“If they’re not going to provide information, they need to tell us, basically, what they’re not providing and why,” said Sandy Bahr of the Sierra Club.
SRP said in an email that it had not had time to review the lawsuit.
