Arizona Public Service Company (APS) has been supporting the growth of photovoltaic (PV) and other distributed generation technologies through direct consumer rebates since 2002. The Company’s efforts in this area have resulted in rapid growth in the number of residential grid tied PV systems.

This level of growth can create problems. Incentive levels and program participation rates risk having the program run out of money available for new incentive reservations in the mid 2nd Quarter of 2010.

In response to the current situation, APS asked Vermont Energy Investment Corporation (VEIC) to conduct a rapid analysis of residential grid-tied PV incentive levels and structure and make recommendations for immediate actions that can eliminate or minimize the potential market disruptions.
