How PJM and its stakeholders would approach gas-electric contingencies during a cyber or physical threat was at the center of the Dec. 12 Operating Committee meeting.
Stakeholders and PJM reviewed resilience initiatives for gas pipeline contingencies – in both “normal” mode (constrained electric/gas system conditions) and “conservative” mode (cyber/physical threats). They also covered the process flow diagrams for both scenarios.
The current PJM initiative aims to evaluate operating procedures for gas infrastructure contingencies under both gas supply failures and cyber/physical threats. Some members were particularly concerned with compensation under emergency scenarios.
Ken Seiler, executive director – System Operations, said that PJM has had a number of conversations with both the gas pipelines and generation owners to fully understand these scenarios
“PJM’s goal is codify our actions in the manuals so all participants are aware what our triggers will be and the actions we will take should one of these scenarios occur,” said Seiler. He agreed with stakeholders that talking compensation is not a conversation to be had in the middle of an emergency situation.
PJM will work with stakeholders to further define gas infrastructure triggers and operating procedures. Next steps include a discussion at the Markets & Reliability Committee on the manual language revisions to provide additional details and confirm specific contingency assumptions and infrastructure redundancies.
Andrew Levitt presented updates from the new Distributed Energy Resources Subcommittee (first meeting Dec. 15). PJM moved from handling DER issues through special sessions of the Market Implementation Committee and Market & Reliability Committee to the subcommittee in order to expand past market-only issues and scope.
Because the new subcommittee’s activities expanded to the role of DER in operations and planning as well as markets, Levitt encouraged more stakeholder participation. There will be an education session on Jan. 26 to bring members up to speed on activities and lay out what the subcommittee will cover.
PJM also reviewed winter weather preparations. Generators have until Dec. 15 to review the cold weather preparation guideline and checklist in eDART. The checklist provides generators with a guide to reduce problems during cold weather events. PJM has a target date of early January 2018 for its periodic generator operator survey, which will focus on units with fuel storage or emission limitations (as identified in the 2017 fuel survey).
Other Committee Business
The approved changes did not, however, include PJM’s proposed gas-electric contingency language. PJM and stakeholders will confer on that language and have material ready to discuss at the Dec. 21 Markets & Reliability Committee meeting.
