Agenda
• Present areas of OPUC policy and practice likely to intersect with DSP
• Focus on most relevant regulatory practices, not exhaustive
• Goal: prompt thinking and dialogue to continue throughout investigation
• Not recommendations or proposals

Response Programs
1. Existing interconnection insights
2. Potential overlap with DSP optimization

Interconnection and DSP
Typically Interconnect to Distribution System
11
Interconnection Overview
Net Metering (Up to 2 MW)
Small Generator
(Up to 10 MW*)
Community Solar
(25 kW - 3 MW)
Large Generator
(> 20 MW)
*The definition of small generator for FERC-jurisdictional interconnections is up to 20 MW
Public queue and studies(SG and LG only)
Small generator annual report
UM 2001 distribution system data
Complaints and disputes
Interconnection reform investigations 12
Regulatory Processes
Net metering report
Existing processes
13
Emerging Issues
Transparency Planning
How to help generators site and design projects
How to keep changing study and queue data fresh and consistent
What is a reasonable system upgrade cost for a generator to bear?
How to vet utility studies and consider alternatives to system upgrades
14
Potential Overlap
Near-term:• To what degree can interconnection data
enhance DSP? To what degree can DSP enhance interconnection transparency?
• How should investments in interconnection transparency and tools be considered? What additional tools are needed?
• In what ways does interconnection information function as an input and/or an output of the DSP process?
Longer-term:• How should utility plans
account for future interconnections?
Thank you!

Smart Grid Report Overview
• The “smart” grid is now just “the grid”
• What smart grid report elements should carry over to the DSP?
• What should be added to DSP that was not in the smart grid reports?
• Why do we value non-wired solutions?
• Are solutions portfolios?
• Besides wired solutions, what other costs might distribution planning avoid?
