Technology cost is important but does not seem to be reflected here, nor is it clear what candidate resources are provided for the model to pick. What additional technology is being considering in the model, e.g. CCS, long duration storage, etc.?

Dominion Energy continues to evaluate multiple technologies for long term planning purposes.  It is expected that the IRP will include at least qualitative discussions of technologies, such as carbon capture and sequestration/storage (CCS) and long duration storage.  For any technology included in the modeling, costs to build and operate that technology are inputs into the model. 

Additionally, Dominion Energy continues to evaluate both hydrogen and small modular reactors (SMRs) for long-term planning purposes. It is expected that the Integrated Resource Plan will include discussions and/or modeling on both hydrogen and SMRs.  Small Modular Reactors (SMRs) will be made available for the model to select as part of the Integrated Resource Plan modeling.  Geothermal generation is currently not a resource type available for the model to select.

Other Stakeholder Questions and Answers

• How does population and business growth affect the expected energy demand and how does Dominion Energy plan to meet the growth?
• Please provide a clear answer as to what extent this process will: i) give stakeholders an opportunity to access the final set of inputs and assumptions the utility will use for each plan and to provide feedback; ii) give stakeholders access to the modeling results and an opportunity to provide feedback on these results; and iii) the extent to which the utility will produce new modeling runs or an entirely new alternative plan based on stakeholder feedback.
