    Description: This Resource Registration Glossary Revision Request (RRGRR) adds three categories of data: Voltage limits are needed for Resources to indicate that their substation transmission level equipment is limited to a certain range of voltages. The relay loadability limits indicate the limits of loading for certain equipment. Geomagnetic Disturbance is a newly emphasized risk to the grid. The addition of geomagnetically-induced currents and the presence of blocking devices will allow for the study of any vulnerability due to Geomagnetic Disturbance. The addition of a Most Limiting Single Element (MLSE) allows a Resource Entity to identify an MLSE even if that element affects a line not owned by a Resource Entity.
