Review of Energy Efficiency Supply Curves
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. The tracker is updated regularly, and we mostly reflect those changes in the list below.
- Use this feedback form 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". - 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.
- Email workbook with comments 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 products have been reviewed:
- Non-Residential Demand Response Products (May 2025)
- Residential Direct Load Control Products (March 2025)
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.
Email questions to Joe Walderman.
