Arizona Corporation Commission staff has rained on a proposal by Arizona Public Service Co. to enter the rooftop solar installation market.
Earlier this year, APS proposed a residential rooftop solar program where it would lease homeowners’ roof space to install photovoltaic collectors and credit the value to the power bills. The utility would own the system, the power generated and maintain the equipment.
As many as 3,000 homes would have been eligible for the initial program if it were approved by the ACC. Slated for a Nov. 13 hearing, ACC staff is recommending denial.
ACC staff found that APS does not need to enter the solar installation market, which until now has been a competition among private firms. The staff also said that the power company’s program would be more expensive to implement than current solar power programs. The recommendation needs approval by a majority of the commission.
Commission staff said that the APS proposal would cost ratepayers $22.2M over 20 years. An alternative recommendation from the staff would cost the utility a one-time $2M charge that could come from existing programs without being passed to ratepayers.
