As a result of the Coronavirus (COVID-19) outbreak, ERCOT has implemented a mandatory work-from-home policy for all ERCOT staff not required to be on-site to fulfill ERCOT’s functions. During this time, ERCOT will have reduced staff available to receive, distribute, and manage incoming postal mail, deliveries, and faxes on a daily basis. ERCOT strongly encourages Members and others to submit written information to ERCOT via email, and submit necessary membership funds to ERCOT via wire transfer rather than by check.

Membership in ERCOT is open to any entity that meets any of the segment definitions as set forth in the ERCOT Bylaws. Members must be in an organization that either operates in the ERCOT region or represents consumers within the ERCOT region. A member applicant may join as a corporate, associate or adjunct member and will be subject to the criteria set forth in the ERCOT Bylaws. A member applicant must apply for membership through an authorized officer or agent.

The Members are organized by the following Market Segments: 

  • Adjunct
  • Consumers
  • Cooperatives
  • Independent Generators
  • Independent Power Marketers
  • Independent Retail Electric Providers
  • Investor-Owned Utilities
  • Municipals
