Operationalize Gas-Electric Contingencies Purpose & Intent Current initiative is to create operating procedure to evaluate gas infrastructure redundancy and operationalize gas contingencies under − −

• • • •

Electric/Natural gas infrastructure constraints/failures and External threat conditions (cyber/physical threats)

Define Gas infrastructure redundancy criteria Refine Gas unit exposure time Define Operating procedures to include triggers, thermal/voltage and reserve requirements. Define new process with – Decision flow diagram – Outline assessment steps in Operating Memo and PJM Manuals.

Gas Pipeline Contingency Process Summary Normal Mode – Constrained Electric/Gas System Conditions

Conservative Mode - Cyber/Physical Threat Conditions

Procedure Triggers

Cold/Hot Weather Alert Capacity Emergency Pipeline Operational Flow Orders (OFO) Pipeline Maintenance Outages / Force Majeures

Pipeline Cyber/Physical Threat

Decision Criteria

Compressor station / Gas pipeline sufficiently redundant?

Credible threats to multiple pipelines in the same area?

Contingency Refinement

Exclude Dual Fuel Units (Post-contingency switch) Exclude Multiple Pipeline Units (Post-contingency switch)

Exclude Dual Fuel Units (Pre-contingency switch) Exclude Multiple Pipeline Units (Pre-contingency switch)

Next Steps Next Steps: • • • •

Revise Manual 3 & 13 language to provide additional transparency, and details to address stakeholder feedback. Continue outreach to the interstate pipelines, and local distribution companies to confirm specific contingency assumptions and infrastructure redundancies. Continue review of critical contingencies and assumptions with impacted generation owners. Continue to engage stakeholders for their feedback on open items and incorporate member feedback whenever possible as part of implementation

2018 Initiatives: • • •

Addressing Market Settlements issues for PJM requested pre-contingency fuel/pipeline switching under cyber/physical threat conditions. Address potential Environmental/Emissions impacts for oil use. Engage members as part of Market Gateway/Data requirements to support automation
