2027 Event Agenda

For most of three decades, Dominion Energy managed every transmission facility rating subject to compliance monitoring in a legacy spreadsheet application. Engineers calculated the limiting rating by hand, the tool tracked only that single number, and any change simply overwrote what came before. No version history, no peer review, and no automatic warning when a change quietly de-rated a facility and left the grid weaker. That's exactly the kind of gap that could become a compliance issue in a FERC 881 audit. And it gated everything downstream: a new line can't be energized until its ratings are active in the system of record.

This session shows how Dominion's Electric Transmission team replaced that legacy system with FRD: a node-breaker system of record that models every piece of equipment in a facility, not just one rating per device type. Its ratings engine automatically computes the most-limiting element across 264 conditions: 44 temperatures, three operating states (normal, emergency, and load dump), now including solar heating. These flags derate before they reach service, and routes every change through a multi-step peer review where facility-ratings and system-protection teams sign off before activation. A full audit log and version history let Dominion justify any rating to PJM, while a third-party API automates the ampacity and overload calculations that used to be done by hand. The result: one trusted source of ratings truth feeding operations, planning, modeling, and the EMS. And a compliance mandate turned into durable infrastructure.
