How does Dominion Energy show the company has met energy sufficiency in the IRP?

The IRP model will build and purchase enough energy and capacity to meet the PJM reserve margin.  The reserve margin established by PJM, targets a “1-in-10 Loss of Load Expectation (LOLE)”.  PJM plans to that reserve margin to avoid experiencing more than one event (like an outage) every 10 years.
