    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:

    Asset Registration

    An RE’s assets must also be registered. Most RE Asset registration activities include the following:

    • Complete all required Generation Interconnection Change Request processes as described in the Planning Guide, Section 5 located under Guides below.
    • 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.
    • Establish a data link with the QSE. Refer to the ERCOT Nodal ICCP Handbook located under Guides below.
    • Work closely with designated QSE and ERCOT to coordinate planning for the first operating day and unit commissioning.
    • Submit the ERCOT New Generator Commissioning Checklist for approval to energize, synchronize, and complete required commission testing. See QSE Documents below.

    Additional Requirements

    Most REs must also be registered with the Public Utility Commission of Texas (PUCT). Please refer to the Power Generation Companies and Self-Generator Registration area on the PUCT website. The Resource Entity shall register Distributed Generation (DG) in accordance with ERCOT Protocols Section 16, if the DG’s installed capacity is greater than one (1) MW or if the energy is to be accounted for in wholesale market settlements. Please refer to the Distributed Generation section for more information.
