NERC PRC-025 and PRC-027 Compliance Deadline Support

NERC PRC-025 and
PRC-027 Compliance
Deadline Support
OUR SOLUTIONS
Due to the recent COVID situation, NERC has
provided an estimated 6-month reprieve for
the NERC Standards PRC-025 and PRC-027
compliance deadline. This will provide many sites
the needed time to complete the requirements
associated with these standards. EN Consulting
is available to provide expert support for fulfilling
any lingering obligations or full support for the
standards’ requirements.
EN Consulting encourages generator owners to
begin early as communication between the
generator owner and the transmission operator
to obtain the required documentation as well as
any potential mitigations or changes with the
interconnecting transmission owner can be a
lengthy process.
EN Consulting’s PRC-025 and PRC-027 service
offerings includes a comprehensive report
covering technical details such as documentation,
figures, and text which address the following list
of the generator owner’s requirements:
