How will Dominion’s next IRP satisfy Va. Code Ann. 56-599(B)(10)’s requirement to provide “a comprehensive assessment of the potential application of grid-enhancing technologies and advanced conductors,” including whether Dominion will evaluate opportunities for those technologies to defer, reduce, or eliminate the need for new grid infrastructure and, if they are not included in the IRP, provide the required detailed explanation? Will the assessment compare GETs and advanced conductors against conventional transmission solutions using consistent metrics? Will Dominion identify the specific transmission needs, constraints, or candidate facilities where it evaluated non-conventional solutions and include the results with production cost and power flow modeling in the IRP?

The new legislation recently signed by the Governor of Virginia stipulates that the changes would become effective beginning with the 2027 IRP. We are actively considering how to reflect them in IRP assumptions, modeling, analysis, and stakeholder engagement activities. This new legislation is a good example of how IRP requirements continue to grow and evolve. 

Long-term transmission planning is addressed through PJM processes and is outside the scope of this IRP and stakeholder process. For more information on PJM planning, please see https://www.pjm.com/planning.
