PHOENIX — Arizona utility regulators are wading into another contentious issue involving renewable energy.
The Corporation Commission agreed Thursday to review how to account for rooftop solar installations under the state's requirement that utilities get growing percentages of their power from renewable sources.
Arizona Public Service Co. now exceeds the current requirement and wants to be waived from having to count solar installations.
Solar industry representatives oppose that, saying that APS is trying to undercut the renewable-energy mandate.
The Arizona Republic (http://bit.ly/1nfSxpr ) reports that commission members insist they're not going to reduce the amount of renewable power used in the state.
The commission last year resolved a related issue when it agreed to require solar customers to pay a monthly fee to help support the electric power grid.
