Review of Energy Efficiency Supply Curves Process
Starting February 2025, the Council is requesting public comments on energy efficiency supply curves.
How to submit a comment:
- See measures ready for comments in the measure review tracker (direct download). The tracker is updated regularly, and we mostly reflect those changes in the list below.
- Use this feedback form (direct download) and submit it to this folder in Box.
Please use the naming conventions provided in the instructions of the feedback form. For example, completed forms should be submitted as "9P Review Feedback_Your Organization_Date", and any marked-up supply curve work products should be submitted as "Original File Name_Your Organization_Date". - Feel free to submit multiple feedback forms as needed, so we can respond to and implement feedback in a timely manner.

Review of Demand Response Products
Starting March 2025, the Council is requesting public comments for proposed cost and impact assumptions for demand response products.
How to submit comments and feedback:
- Review products ready for comments from the lists below.
- Provide comments and feedback in the Feedback Form tab of each workbook.
- Submit workbook with comments via email to Joe Walderman.
Please use the naming conventions provided in the instructions of the feedback form. For example, completed forms should be submitted as "NonResDRFeedback_Your Organization_Date".
The following categories of demand response products are posted and available for review:
- Non-Residential Demand Response Products (direct download) – respond by May 15, 2025.
The following categories of demand response products have been reviewed:
- Residential Direct Load Control Products (comment period ended March 31).
Questions about the process? Contact Joe Walderman.
All comments for residential direct load control products were reviewed and any changes made to input assumptions for these products in response to comments or new data before March 20 were discussed in the DRAC at the March 2025 and April 2025 meetings. For more context and background on these assumptions please see the presentation and meeting notes from the February 2025 DRAC meeting.
Please remember that these are numbers intended to represent a proxy demand response resource for the region to the best extent possible, with the understanding that certain actual cost and impact parameters may vary significantly from utility to utility.
Cost Assumptions Built into Generating Resource Reference Plants
A reference plant is a collection of characteristics that describe a resource technology and its theoretical application in the region. It includes estimates of typical costs, logistics, and operating specifications. These reference plants become resource options—along with energy efficiency, demand response and distributed energy resources — for the Council’s power system models to select to fulfill future resource needs. The Council develops a defined set of reference plants that represent the range of resources to be considered in planning.
This workbook captures how these reference plant costs were developed, what sources were drawn upon, how cost curves are applied, etc. This is currently a draft that will be finalized for the publishing of the 9th Plan.
Send any coments on this workbook to Annika Roberts.
