About Today’s Webinar • This webinar is a Special Public Meeting • Today’s session is being recorded and will be a matter of public record • If you are considering sharing or discussing any confidential information please keep in mind it will become public 2
Agenda 1. Welcome - Nick Sayen, OPUC Staff 2. Zoom logistics and participation - Katie Wu, Gridworks 3. Agenda, Desired Outcomes and Review - Nick Sayen 4. Integrated Resource Plan - Rose Anderson, OPUC Staff 5. Transportation Electrification Plan - Eric Shierman, OPUC Staff 6. Public Purpose Charge - Anna Kim, OPUC Staff 7. Next Steps - Nick Sayen 4
Desired Outcomes • 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 5

Integrated Resource Plan (IRP) Overview • Utility files 20- year plan pursuant to OPUC’s IRP Guidelines • IRP seeks to meet forecast needs of customers • Distribution system not often a major focus • Goal: Best combination of cost and risk for utility and customers 8
Integrated Resource Plan • Current inputs to the IRP • Load forecast: • Electric Vehicle (EV) forecast • Distributed Energy Resources (DER) forecast • Energy Efficiency (EE) acquisition (sometimes) • System topology (high-level) • Policy • Information on new and existing resources 9
Integrated Resource Plan • Current outputs from the IRP • Resource acquisition: • Generation and transmission • Demand response (DR) • Efficiency • Other plans: • Other means of reducing cost and risk (e.g., retiring or selling assets) • Studies • Stakeholder processes 10
IRP and DSP Inputs and Outputs Inputs/outputs of IRP and DSP potentially similar: • IRP inputs (high-level): • Potential DSP inputs (locational): • Load forecast • Load forecast • EV forecast • EV forecast • DER forecast • DER forecast • IRP outputs (high-level): • Potential DSP outputs (locational): • Efficiency and DR acquisition • Efficiency and DR acquisition • Utility-scale generation • Utilization of DER services (DSP) • Transmission upgrades • Distribution upgrades • Non-Wires Solutions • Non-Wires Solutions 11
Flow of Information: Top-down or Bottom-up? For data in both IRP and DSP: • Top-down approach? • High-level, allocate by location • IRP informs DSP • Bottom-up approach? • Locational detail, aggregate up • DSP informs IRP • Consistent methodologies and assumptions • Resource plan from each process can inform the other • Implementation should be informed by stakeholders and utilities 12
Questions and Discussion Thank you! Rose Anderson, Senior Economist rose.anderson@puc.state.or.us 503-378-8718 13
Transportation Electrification Plan Eric Shierman, OPUC Staff 14
Transportation Electrification (TE) Plan Overview • Section 20 of SB 1547 • Order No. 19-134 (AR 609) established the plan guidelines as OAR 860-087-0020 • Condition of the transportation electrification market • Summary of the electric company’s programs • How the programs accelerate transportation electrification • Supporting data • Company’s impact on market competition • System impacts • Carbon reduction 15

Which TE Plan elements should inform a future DSP? • IRP analogy: load forecast • Power flow study • PGE : “PGE did not conduct power flow analyses to determine EV hosting capacity or estimate locational value. Such analyses will be done in concert with other new loads coming to the system through the course of the DRP (the guidelines of which are being established through Docket No. UM 2005). Through that plan, we aim to identify where system constraints may exist and what strategic deployments of DERs could mitigate those constraints.” TE Plan, September 30, 2019 • PacifiCorp : “To study potential impacts of higher levels of residential electric vehicle adoption, sensitivities representing electric vehicle market share of 12% and 14% by 2025 were analyzed. After adjusting the baseline to reflect the impacts of potential new electric vehicle adoption, power flow analysis was performed using time series analysis and peak feeder loading to evaluate the impacts of increased adoption on existing equipment, devices, and voltage delivery.” Attachment 5, Potential System Impact Study, September 2018, TE Plan, February 3, 2020 • What other stakeholder interests would a general power flow study help inform? • Is power flow modeling to DSP what capacity expansion modeling is to the IRP? 18

Public Purpose Charge Anna Kim, OPUC Staff 20
Potential Points of Intersection Energy Public Purpose Efficiency and Distributed Public Purpose Charge Charge Demand Generation Response Interconnection Load Forecasting Programs System System Monitoring and Assessment Control Project Design and Grid Needs Construction Assessment Solution Identification 21
Public Purpose Charge: A Resource for DSP • Public Purpose Charge is paid for by ratepayers • Public Purpose Charge pays for: • Energy efficiency in schools (ODOE) • Low income weatherization (OHCS) • Self-directed energy efficiency for large customers (ODOE/Energy Trust) • Energy efficiency (Energy Trust) • “Above - market costs” of renewables (Energy Trust) • These services have cost-effectiveness requirements that can, in the future, incorporate locational values 22
Points of Interaction with DSP It’s more than a non -wires alternative! How can public purpose funds best support distribution planning? Who can we partner with? How can we be more proactive and less reactive? Here’s some data that could be helpful: • Billing analysis • Related market research • Participant information (solar, storage, • Energy burden new buildings, etc.) • Baseline equipment information 23
Points of Interaction with DSP How do we identify the best opportunities for leveraging investments between public purpose funds and distribution system planning? We have set up processes to combine funds and handle attribution both between different public purpose charge categories and with other funding sources • There are opportunities to pair public purpose funds with other funds to support DSP projects • As planning horizons and interest grows, there will be choices about where to invest, and how to invest in those locations 24
Proactive Example “We need a substation-- now!” Planning Building NEED ! 25
Proactive Example “We need a substation-- now!” EE+DR, solar+storage, Planning Building NEED ! batteries? microgrid? Substation? Who wants “What are to partner with us? the options?” Building Planning NEED ! 26
Discussion • How can we best use public purpose funds to support distribution system planning? • What new opportunities are available to pair public purpose funds with other funds for DSP? • In the future, if there is a lot of interest in DSP-related investments, how do we prioritize project locations and project types? 27
Keep the Ideas Coming Thank you! Anna Kim, Senior Utility Analyst anna.kim@puc.state.or.us 503-378-6360 28
