The U.S. Department of Energy and the North Carolina Clean Energy Technology Center are excited to announce that a new, modernized DSIRE is under construction. The new version of DSIRE will offer significant improvements over the current version, including expanded data accessibility and an array of new tools for site users. The new DSIRE site will be available in December 2014. Staff are currently working hard on the new version of DSIRE but are also maintaining the content of the current version of DSIRE. Thank you for your continued support and patience during this transition. We hope you are as excited for December as we are!

Note: The Arizona Corporation Commission (ACC) recently approved modifications to some elements of APS renewable energy programs. Only upfront incentives for solar water heating are now available.

Through the Renewable Incentive Program, Arizona Public Service (APS) offers customers who install solar water heating systems the opportunity to sell the renewable energy credits (RECs) associated with the energy generated to APS. APS uses the RECs to demonstrate compliance with the state's Renewable Energy Standard (RES). While there are no longer any up-front incentives or production-based incentives available for grid-tied PV systems, APS offers a streamlined process to interconnect renewable distributed generation. Please see for applications and resources.
