Generating Availability Data System User Group (GADSUG)

​The Generating Availability Data System User Group (GADSUG) is to implement a uniform approach to reporting and measuring North American generating plant availability, performance and other related reliability data.

To accomplish its purpose, the GADSUG performs the following activities:

  • Reviews and recommends new generation availability data that should be subject to mandatory collection by NERC.
  • Reviews additions and changes to the GADS Data Reporting Instructions (DRIs).
  • Analyzes, assesses, and reports on trends and risks to reliability from generator availability and performance.
