Today’s LiveWire Spotlight looks at the third posting of the updated Transmission Planning Performance Standard addressing Protection System single points of failure as directed by FERC in Order 754. Once approved, contingencies P5 and P8 will address a delay in Fault Clearing due to a concurrent Fault and a Protection System failure.
The third draft of TPL-001-5 and its supporting materials have been posted on the NERC website for a 45-day review and concurrent ballot. Clients have until April 9, 2018 to return their comments and votes to the project team.
