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

  • 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 (IRP) Overview

slide-8
SLIDE 8
  • 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

Integrated Resource Plan

SLIDE 9

10

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

IRP and DSP Inputs and Outputs

  • IRP inputs (high-level):
  • Load forecast
  • EV forecast
  • DER forecast
  • Potential DSP outputs (locational):
  • Efficiency and DR acquisition
  • Utilization of DER services (DSP)
  • Distribution upgrades
  • Non-Wires Solutions
  • Potential DSP inputs (locational):
  • Load forecast
  • EV forecast
  • DER forecast
  • IRP outputs (high-level):
  • Efficiency and DR acquisition
  • Utility-scale generation
  • Transmission upgrades
  • Non-Wires Solutions

Inputs/outputs of IRP and DSP potentially similar:

slide-11
SLIDE 11

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

Flow of Information: Top-down or Bottom-up?

slide-14
SLIDE 14
  • 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

  • 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?

Which TE Plan elements should inform a future DSP?

Public Purpose Charge

Public Purpose Charge Distributed Generation Interconnection

Potential Points of Intersection

Public Purpose Charge

21

Energy Efficiency and Demand Response Programs

slide-20
SLIDE 20
  • 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

Public Purpose Charge: A Resource for DSP

slide-21
SLIDE 21

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:

23

Points of Interaction with DSP

  • Billing analysis
  • Participant information (solar, storage,

new buildings, etc.)

  • Baseline equipment information
  • Related market research
  • Energy burden
slide-22
SLIDE 22

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

  • How can we best use public purpose funds to support distribution

system planning?

  • What new opportunities are available to pair public purpose funds with
  • ther 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?
