Operating Committee rolls out new stakeholder communication tool, reviews July events

2076

Beginning in September, Operating Committee members will see a new slide added to meeting presentations that aims to better communicate timelines associated with changes coming through the stakeholder process and help participants navigate large volumes of meeting materials.

Rebecca Carroll, director – Member Relations, introduced the stakeholder impact slide at the Aug. 7 meeting. The slide will identify the groups expected to be most impacted by a change, what action might be required, and corresponding deadlines.

The pilot is a response to feedback from the 2017 Stakeholder Survey, in which respondents requested more focused communication, she said.

The slide first will be used in meetings of the Operating Committee and Tech Change Forum because those are areas where many manual changes and other initiatives start, Carroll said.

PJM will use October to gauge presenters’ and stakeholders’ feedback on the new slide before rolling it out more widely at other meetings. It could be used beginning in December at the Markets and Reliability, Market Implementation and Planning committees.

The Operating Committee learned from Chris Pilong, director – Dispatch, that PJM, with assistance from the NERC Resource Subcommittee, is analyzing a low frequency event on July 10.

The scheduled frequency was 59.98 Hz when a pseudo-tied generator tripped at 3:46 p.m. A low frequency of 59.903 Hz occurred. The PJM tie error was about 900 megawatts low when PJM called on synchronized reserves. At its lowest point, the tie error dropped to 1,800 MWs low, Pilong said.

The frequency drop was caused by the loss of multiple generators and, potentially, a bad interchange schedule on the Eastern Interconnection, he said.

While not normal, such frequency drops do occur every few years. The RTO saw a similar frequency deviation in 2014.

Of particular interest, he said, is a 0.04 Hz drop for which PJM is working with NERC to determine a cause. The results are expected to be shared at next month’s meeting.

Pilong also shared a report on the July 18 Lonesome Pine load shed event. In that incident, transmission equipment tripped out of service while the 138-kV Buckhorn-Lonesome Pine line was out of service for scheduled maintenance, leading AEP to shed about 32 MW of load.

The outage, which lasted from 11:14 a.m. to 12:37 p.m., affected approximately 11,860 customers in West Virginia and Virginia. Voltage violations were in a localized load pocket, and no possible generation dispatch would have mitigated the outage.
