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 "DRFeedback_Your Organization_Date".
Products Under Review:
-
All Demand Response Products - please comment by June 25, 2025
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.
