Introduction
• Operating Procedure No.6 (OP-6) is being revised to:– Establish a separation of System Restoration concepts and
responsibilities (OP-6 revision 11) from the System Restoration Plan and technical data (new Master/Local Control Center document suite M/LCC 18)
– Reflect changes in the application of present and future resources to prioritize and support regional restoration
• NERC Reliability Standard EOP-005-2 and EOP-006-2, effective 1 July, 2013, establish new Requirements that need articulation in the stated objectives
• Document changes are intended to consolidate information, instructions and forms

Major Changes – Main Body
• Technical data is relocated from OP-6 and populated in a newly created M/LCC 18– Consolidation of technical data sources for ease of System Operator use/access
when required – OP-6 document suite public information remains public in transition to M/LCC 18
document suite
• Identify the restoration objectives from the Reliability Coordinator (RC) perspective to NERC Reliability Standards requirements
• Add language that articulates completion of RC restoration objectives and ongoing ISO responsibility to coordinate LCC recovery actions
• Update and enhance responsibilities for ISO, LCC and Market Participants
