Is Dominion planning on doing any load forecast sensitivities, including forecasts with lower levels of demand growth, to represent the uncertainty around data center/large load growth in the coming years and decades? If so, what is Dominion's preliminary approach for modeling load sensitivities for this IRP?

Please refer to the Q&A from IRP Conference 1 (https://devirp.dominionenergy.com/stakeholder-questions-and-answers/will-you-do-sensitivity-tests-for-variations-of-load-forecasts-including-the-data-center-load-forecast). Plan sensitivities, including for the load forecast, were discussed in Chapter 5.3 of the 2025 IRP Update.

We anticipate having similar sensitivities in the 2026 IRP Filing.
