Integrated Grid Planning
IGP Stakeholder Technical Working Group Meeting June 17, 2021
Meeting Objectives
- Finalize recommendations for bookend sensitivity assumptions and assumptions for “best guess” DER programs
- Provide stakeholders information on the purpose of the LoadSEER model and how it is used to inform DER forecasts
- Determine if EV charging assumptions are reasonable, if not, what adjustments should be made
Key Questions
- What assumptions should be modified/considered to develop a revised DER forecast based on the “best guess” of new DER programs?
- What is the intended use case for disaggregation of forecasts by location and rate class?
- What level of granularity is needed in later years (i.e., post-2030)?
Agenda
- Continue discussion on updated DER forecasts
- Assumptions for best estimates of the tariff and program values for DER, EE and EoT
- Discussion on how LoadSEER is used to develop and/or inform DER forecasts
- Continued discussion on bookend sensitivities
- The use of LoadSEER to inform location of DER layers in the bookend sensitivities
- Discussion related to further disaggregation forecasts by location and rate class
- Discussion on EV managed and unmanaged charging assumption
- Stakeholder Presentation: Blue Planet
- legislative updates on EVs in Hawai‘i, and
- how other jurisdictions account for EVs in IGP.
- Hourly charging profiles for managed charging and associated assumptions
- Stakeholder Presentation: Blue Planet
Deliverables in Response to Stakeholder Feedback
- Grid Needs Assessment – Modify the bookend scenarios and finalize EV charging assumptions
- Inputs & Assumptions – Modify the DER forecast for best estimates of new DER programs
