PJM.com HTTPS Update & Data Feed Retirements

PJM will be performing a security update and retirements on Wednesday, August 15. To enhance security, the PJM corporate website address and subsidiary sites will change from http to https beginning at 5 p.m. At that time, users who still try to access pages that begin with http will be automatically redirected to the new https pages. Users with hardcoded links or screen scraping should update their systems to retrieve from the valid https link. The following sites will be affected by the https update:

  • www.pjm.com
  • annualmeeting.pjm.com
  • www.pjmsettlement.com
  • www.jointandcommon.com
  • learn.pjm.com
  • seminar.pjm.com
  • datasnapshot.pjm.com

PJM introduced a new tool, Data Miner 2, to assist with public data feeds in 2017.  Several feeds hosted on pjm.com will retire after 2 p.m. on August 15. PJM will remove the historic files associated with these feeds from pjm.com and ftp on August 17.  Users are expected to update all data feed retirements XLS to Data Miner 2 feeds.
In addition to the pjm.com feed retirements, the original Data Miner tool will be retired on August 15.  All changes noted above have continued to be announced to PJM members and stakeholders at the Tech Change Forum and other stakeholder meetings.

  • PJM must replace expiring security certificates that creates website trust between stakeholder and PJM systems.
  • Google and Mozilla have announced it is upgrading to Chrome 70 and Firefox 63 in October. These upgrades will cause a security error to be generated to stakeholders trying to access PJM Tools if PJM does not update the certificate.

Stakeholder Impact

  • Once PJM replaces the certificate, stakeholders who use browserless user interfaces to access PJM Tools may receive a security error. Access errors will occur if those who use PJM Tools have not updated the security certificates on their systems as well.
