What Is NERC Audit Service?
The NERC Audit Service refers to the formal process used to evaluate whether power utilities comply with reliability standards set by the North American Electric Reliability Corporation (NERC). These audits are conducted by Regional Entities under NERC’s authority.

In simple terms, the NERC Audit Service checks whether utilities are doing everything required to keep the electric grid stable and secure.
