How will the IRP modeling deal with potential risks associated with the availability of imports?

As stated in Appendix 2D of the Company's 2025 IRP Update [https://www.dominionenergy.com/about/our-company/irp], the Company’s PLEXOS modeling uses lower capacity and energy import limits than those found in the transmission import studies to help ensure energy independence and self-sufficiency for the Company’s customers. 

Other Stakeholder Questions and Answers

• Does the IRP make any assumptions about a global human population reduction in future years? How would this affect current planning, short term planning, and long term planning?
• Please provide a detailed explanation of what the model will assume with regard to transmission lines -- when new lines will be added, where, at what cost, and when will the start years be.
