Please see slides 17-18 of the presentation from IRP Conference 1, held May 8, 2026, available here: https://devirp.dominionenergy.com/img/feedback/media/May-8---Stakeholder-Conference-1.pdf. In addition, for a full explanation of these slides, please view the Recording from IRP Conference 1, beginning at time stamp 0:25:20.

Demand side management functions as a “load reducer” and is incorporated in the load forecast, thereby reducing the customer demand the IRP model must build resources to meet.

Other Stakeholder Questions and Answers

• Why does the IRP show net present value (NPV) differently at the portfolio level, rather than applying the same net revenue approach that is used for individual project NPV analyses?
• Can effective load carrying capability (ELCC) values change from year to year? Are there limits to the magnitude of change, or can there be fairly large year-over-year change to ELCC values for specific resource classes?
