​AG Mayes announced that her office has filed expert testimony with the Arizona Corporation Commission showing that Tucson Electric Power’s proposed 14% rate increase is unjustified and could be reduced to just 4% while still maintaining reliable service and a strong credit rating.

The expert testimony demonstrates that TEP is asking customers to pay shareholder profits that are significantly higher than what it actually costs the company to maintain reliable service.

"TEP’s proposal is blatant corporate greed plain and simple. Our expert analysis proves that customers are being asked to pay far more than is needed. Instead of a 14% rate hike, the expert testimony we just filed with the ACC shows that TEP can achieve the same reliability with just a 4% increase by aligning what customers pay with TEP’s actual costs." – AG Mayes
