9/19/2019 19
Potential Grid Mitigation Strategies
Grid planning
• Transmission reinforcements, alternative paths
• Mix and location of generation
• Distributed energy resources
• Microgrids for key loads (connected to grid normally – available for self-supply in emergency)
System hardening
• Upgrade structures
• Underground cabling
• Increased wind withstand ratings
Emergency preparations
• Fuel assurance and increased storage
• Alternative port and delivery options for emergencies
• Increased amounts of critical supplies

Objectives and Ground Rules for Exercise
Objectives• Identify, in more detail, entities within each key sector
• Validate key customer/sector capabilities and needs following a severe event and extended loss of power, including fuel supply challenges
• Identify sector interdependencies
• Provide stakeholder inputs to RWG report on key customer sector grid resilience needs under various threat scenarios
• Identify potential mitigation strategies by sector
Ground Rules• Offer as much input and ideas as possible; be inclusive
• If you feel information is missing, state assumptions and provide inputs based on those assumptions
• Focus is on role of the grid and power supply, not overall recovery from the emergency
