Integrated Resource Planning

Preparing for Oregon’s energy future

Our focus

Planning to make sure we can provide the safe, reliable and affordable electric power our customers need today, tomorrow and over the long term is a constant focus at PGE.

We call this process Integrated Resource Planning, and it’s guided by the Oregon Public Utility Commission with input from customer groups and other stakeholders.

2019 IRP

Work is well underway for the next IRP, which we aim to file in the summer of 2019. In the 2019 IRP, we'll be developing a resource plan that balances future costs and risks while addressing four key themes that reflect our evolving electricity system: technology integration, customer participation, decarbonization, and uncertainty and optionality. To participate in our 2019 IRP public process, please see the IRP Roundtable schedule below or contact us at IRP@pgn.com.

2019 IRP Studies

Decarbonization Study

Customer Insights

  • Market Strategies International (MSI) conducted PGE’s 2017 Customer Insights survey to assess customers’ resource preferences and cost expectations to inform our long-term resource planning and the development of customer service plans and rates. The survey had multiple objectives including understanding customer concerns and preferences as they relate to Integrated Resource Planning, quantifying customers’ perceptions and receptivity to a variety of energy resource options, determining which resource options customers would be most likely to support, and the degree to which certain options would be supported over others, given differences in price and resource mix. MSI presented the results of its study at PGE’s Roundtable 18-1 and the presentation is provided below.

Market Capacity Study

  • PGE engaged consultant Energy and Environmental Economics, Inc. (E3), to conduct a market capacity study that will provide a broad look at regional capacity adequacy in the Pacific Northwest (PNW) to inform our 2019 IRP. The study will provide a PNW capacity load resource balance scenario tool and recommendations for long-term planning assumptions of market capacity available to PGE. E3 presented the study at Roundtable 18-5 on Oct. 28, 2018.
  • Long-Term Assessment of Load-Resource Balance in the Pacific Northwest

Distributed Resource and Flexible Load Study

  • The Navigant Distributed Resource and Flexible Load study is an interdepartmental effort, shared by Integrated Resource Planning, Customer Solutions, and Distribution Planning. The purpose of the study is to create scenario-based forecasts of customer adoption of distributed energy resources (DERs), accounting for interactive effects between programs, incentives, and technologies. The IRP will utilize system-level forecasts for high-, low-, and base-case DER penetration forecasts. The DERs included in this study are: solar, storage, solar+storage, electric vehicles (including charging infrastructure), demand response (including pricing programs), and energy efficiency.

Flexibility Analysis Study

  • PGE is working with Blue Marble Analytics consulting firm to conduct a study assessing system flexible capacity adequacy and the contribution of a range of resources to flexible capacity adequacy. The study will explore options to measure adequacy being used in other regions and develop a methodology to assess the flexible capacity adequacy of PGE’s resource portfolio. Building upon previous flexibility adequacy work detailed in the 2016 IRP, and research of existing literature regarding flexibility, PGE has commenced analysis using the Resource Optimization Model (ROM) to provide an assessment of flexibility adequacy needs under a range of renewable portfolios. As part of the 2019 IRP, PGE will present a methodology and metrics to assess system flexibility adequacy and the ability of potential resource additions to meet flexibility-related system needs.

Supply Side Options Studies

  • PGE contracted HDR Engineering, Inc. to provide generic supply side resource characteristics to inform analysis for the 2019 IRP. The resources considered are wind, solar, battery storage, geothermal, biomass, pumped hydro storage, and natural gas.
  • HDR’s study results are presented the following two reports describing operating and financial characteristics of resources:

IRP goals

Our goal is to provide you with the responsibly generated power you need, when you need it, in a constantly changing energy landscape. We’re always looking for the best combination of resources to balance long term power supply costs and risks for our customers.

How it works

We do this by evaluating the performance likely from different mixes of new and existing, commercially-available generating technologies under a variety of potential future scenarios.

Both supply and demand have roles

By “resources,” we mean supply (existing or new generating projects, or wholesale power market purchases) and demand (like energy efficiency or other ways to reduce the amount of power customers need or when they need it). Both are important to any electric utility planning process.

We conduct cost and risk analysis over a planning horizon of at least 20 years. Throughout the IRP process we share with customer groups, regulators and other stakeholders the results of our research, analysis and findings on anticipated resource requirements and alternatives for serving our customers’ future electricity needs.
