    Resource Entities

    An Entity that owns and/or controls a Generation Resource, Load Resource, and/or a Non-Modeled Generator is registered with ERCOT as a Resource Entity.

    Resource Entities (RE)

    Registration

    The Resource Entity (RE) Application for Registration can be found in Section 23 of the Protocols. Each RE must complete the application and identify a Qualified Scheduling Entity (QSE) to complete the ERCOT registration requirements.

    REs should review the following important information based on their planned ERCOT participation:

    • Submit the Resource Asset Registration Forms, located under Asset Registration Documents below.
    • Complete the design and installation of an ERCOT-polled settlement meter, as described in the Settlement Metering Operating Guide located under Guides below.
