GIS Role
• One point of contact for customer (or authorized agent) with regard to interconnecting systems
• Coordinate various activities, including engineering, metering, and contract administration
• Responsible to ensure system is installed as design indicates and operating according to Rule 21
• Two types of solar interconnections: NEM and non-NEM options
Self-Generation Incentive Program

Interconnection Application and Agreement
• A separate application and process from CSI (recently updated)
• Process runs parallel with CSI/SGIP• Application must be complete and
include required documents for review • Execute Inspection and Interconnection
Agreement before a system is permitted to operate

Project Review NEM Non-NEM Analysis of system Single-line diagram (SLD) SLD, Site Diagram Protection n/a in most cases Larger systems/interconnection at
which level (distribution vs transmission)
Metering (revenue meter)
Bi-directional required No metering change
Net Gen Meter (NGOM)
Dependent upon size and/or selection (EPBB vs PBI); meter must conform to standards
AC Disconnect Self-contained meter – not required; Transformer-rated meter- required (Table 7-3, 2007 PG&E “Green Book”)
Self-Generation Incentive Program

Inspection
• Check system to ensure built as designed (matches SLD)
• Install bi-directional meter (NEM)
• Verify installation of AC disconnect and appropriate signage (if required)
• Install Net Gen Output Meter, if needed

Process Improvement
• Change in AC disconnect requirement policy – November 2006
• NEM-MT has been approved to simplify projects with solar combined with other generation technologies
• Underway: simplification of application, to be combined with the Agreement for NEM

Overall Timeline
• NEM projects- generally less than 30 business days
• Non-NEM- within 60 days, if all required docs/signatures and construction is on schedule
