PJM Firewall Update on May 11

PJM is performing another firewall upgrade on Thursday, May 11, from 8–9 p.m. (EDT).

The applications affected will experience intermittent outages during the planned upgrade. Any additional updates prior to the upgrade can be found on the outage page on PJM.com.

Before the start of the upgrade, members should download any information they might need to access during the scheduled outage.

The applications that will be included during the May 11 firewall upgrade are:

  • Billing Line Item Transfer
  • eCredit
  • ExSchedule
  • InSchedule
  • Market Settlements Reporting System
  • Power Meter
  • Transmission Owner Access

PJM is intentionally making its systems unavailable now to ensure uninterrupted data availability in the future for its stakeholders. This is a multi-year effort to enhance PJM’s cyber infrastructure to improve scalability, reliability and security. The scope for 2017 is to replace internal firewall hardware.

The next planned outage is May 25, 2017.
