For the first time in five years, the Arizona Corporation Commission (ACC) has finalized a review of its rates and customers could see a 4.5 percent increase in electric costs.

On average, residential monthly bills are expected to increase approximately $6. The increase will help fund “a smarter, cleaner energy infrastructure” designed to extend a wider range of options to match household preferences, according to ACC.

While the new rates became effective Aug. 19, ACC said that customers don't need to take any action at this time. Representatives will contact account holders in the fall to explain new rate plan choices.

“Nearly 30 stakeholders supported the agreement, which encompasses a wide range of customer interests and shows what can be accomplished when people come together to resolve complex issues like Arizona’s energy policy,” according to a Gilbert Chamber of Commerce press release.

As a result of the rate change, customers will see a foundation for future rooftop solar programs for moderate-income individuals, surplus energy rebate benefits, more robust program funding, customer assistance in hardship circumstances, a streamlined discount for low-income customers and business rate possibilities.

Additionally, existing solar customers will receive transition assistance as the system adapts to new technologies.
