What’s Changing in the NERC Registration Criteria?

NERC is moving forward with formal changes to its Rules of Procedure and Registry Criteria—and it’s going to reshape who gets pulled into compliance.

At the center of this update is the creation of a new registration category:
Generator Owner – Inverter-Based Resources (GO-IBR).

This function is being added to ensure that smaller-scale IBRs—which have traditionally flown under the regulatory radar—are now formally recognized for their potential impact on grid reliability.

1. Projects between 20 MVA and 75 MVA that are connected to transmission lines at ≥100 kV.
2. Projects ≥20 MVA in total capacity, even if they interconnect at <100 kV voltage levels.

That means whether your IBR project is grid-scale or mid-sized—and whether it’s tied into the transmission system or a sub-transmission network—you’re now within scope if your system crosses the 20 MVA line.
