With a renewable energy initiative ready to be filed next week, a state utility regulator is filing his own proposal, one that electric companies are likely to find more attractive.

The Palo Verde Nuclear Generating Station is the nation’s largest power producer, and if the Clean Energy for a Healthy Arizona initiative appears on the ballot in November, voters will decide the plant’s future.

Hoping to incite a blue wave in Arizona, billionaire mega-donor Tom Steyer will pour at least $2 million into state elections this year.

Afraid that voters might like a renewable energy mandate, the state's largest utility is working with lawmakers to put its own alternative on the November ballot.

Ignoring last-minute requests for a veto, Gov. Doug Ducey signed legislation Friday to protect utilities from having to generate more of the power sold to their Arizona customers from renewable sources.

State senators voted Wednesday to give utilities a way to avoid having to get half their electricity from renewable sources by 2030 even if voters mandate that they do so.

The state’s largest utility wasted no time in spending money to discredit a ballot measure that seeks to increase renewable energy goals.

A judge won't help Bob Burns force Arizona Public Service to disclose the money it has spent -- and may spend in the future -- to elect candidates of its choice.

Pinnacle West Capital Corp., parent company of Arizona Public Service, has donated $10,200 to the Ducey for Governor campaign through its political action committee.
