Today’s LiveWire Spotlight looks at latest posting of PRC-027-1, the NERC standard requiring coordinated assessments between adjacent GOs, TOs, and DPs to validate the response of interconnecting BES Protection Systems to electrical Faults. In Draft 4, the project team has added language primarily addressing situations where the interconnected entities do not agree that a new Protection System Coordination Study is necessary.

PRC-027-1 and its supporting documentation have been posted for a 45 day review period and concurrent vote. Clients have until December 18, 2013 to return comments on the standard and to submit their ballots to the project team.
