    Customers with solar electricity (PV) panels first use the electricity they generate to meet their own power needs.  Under present Arizona Corporation Commission (ACC) rules, when customers send excess power to the grid, they receive full kWh credit on future bills and can roll over this excess from month to month.  In October of each year, Tucson Electric Power (TEP) pays customers at wholesale rates (roughly $.03/kWh) for any power sent to the utility and not used during the year.

    In 2014 and 2015, TEP and Trico (along with Salt River Project and Arizona Public Service and several Arizona electric co-ops) have sought to change the rules so that the excess power is valued at much lower rates rather than full retail rate credit.  In addition, the utility companies have proposed additional fees and charges that would make solar more expensive.  The ACC will decide these issues in 2016.
