Certification requirement (SOC 51-8012)
NERC’s system operator certification applies to the bulk electric system. The bulk electric system is currently defined as voltage of 100kv or higher. Operators staffing desks operating facilities less than 100 kV do not meet the requirements of PER-003, so they are not currently required to hold a valid NERC System Operator Certification credential. Entities may choose to do so at their own discretion.
