Arizona utility regulators are set to make their first major decision involving Arizona Public Service Co. since two regulators won election last year with the support of independent political groups widely thought to be funded by APS.
APS has asked the five-member Arizona Corporation Commission to increase the monthly charge for rooftop-solar customers. In a landmark 2013 decision, the commissioners agreed that rooftop-solar customers avoid paying some of the fixed costs associated with maintaining the power grid because they rely on the grid throughout the day to supplement power from their solar panels.
