Retail Market Testing Flight 0618

    Load Serving Entities

    Load serving entities (LSEs) provide electric service to end-users and wholesale customers. 

    LSEs include the competitive retailers (CRs) that sell electricity at retail in the competitive market. A CR may be (1) a retail electric provider (REP), which contracts with qualified scheduling entities to provide scheduling services for their load customers, or (2) a municipally owned utility or co-operative that opts to offer customer choice (an opt-in entity).

    LSEs also include non-opt-in entities (NOIEs), which are electric cooperatives and municipally owned utilities that do not operate as CRs and do not plan to offer customer choice.

    Load Service Entities (LSE)


    Register with ERCOT as a CR (a REP or an opt-in entity) or a NOIE with the form below.


    CRs must be certified by ERCOT. Please read more about Texas Retail Market Testing and the latest test flight.

    REPs must also be certified by the Public Utility Commission of Texas (PUCT). More information on that certification process may be found on the PUCT website at Retail Electric Providers Certification and Reporting  .
