Generator Deactivation Notices

Last Updated: 4.8.2025

Official Generator Deactivation Notices are sent via email to generatordeactivation@pjm.com, and include the following required information:

  • Indication of whether the unit is being retired or mothballed
  • The desired Deactivation Date (which must be compliant with OATT Part V, Section 113.1 provisions)
  • If mothballing, a good faith estimate of the time period the generating unit will be out of service

Following receipt of the Notice, PJM will notify the Independent Market Monitor, and also notify the appropriate Transmission Owner(s) of the request with the agreement of the Generation Owner or designated agent. PJM will initiate a preliminary analysis of the request.
