Arizona Interconnection Standards and DG/CHP Policy

The Intermountain CHP Center and Initiative are participating extensively in the Arizona Corporation Commission working group on developing interconnection standards. The draft interconnection rules (in progress) combine elements of the interconnection standards from FERC, Wisconsin, New Jersey, Texas, and the 1999 Arizona standards. They will have three different levels/processes for interconnection:

• Level 1 Super Fast Track: Certified inverter-based systems 10 kW and under
• Level 2 Fast Track: Certified systems 2 MW and under
• Level 3 Study Track: All other systems 10 MW and under.

After finishing interconnection, the working group will work on net metering, rates (including standby rates), and DG programs. Besides the Intermountain CHP Center, participants include Commission staff, utilities, and solar advocates.
