Transmission/Distribution Service Providers
Transmission/distribution service providers (TDSPs) own or operate for compensation the equipment or facilities to transmit and/or distribute electricity in Texas. TDSPs are regulated by the Public Utility Commission of Texas (PUCT) and are required to provide non-discriminatory access to the grid.
Each entity that operates as a transmission service provider (TSP) or distribution service provider (DSP) within the ERCOT region, including municipally owned utilities (MOUs) and electric cooperatives, shall register with ERCOT as a TSP, DSP or both as applicable. Any DSP operating only outside of the ERCOT region but within Texas ("non-ERCOT DSP") shall also register as a DSP, but non-ERCOT DSPs are not required to comply with sections of the protocols that relate only to operations within the ERCOT region.
DSPs operating within portions of Texas in areas where customer choice is in effect (including opt-in MOUs and opt-in cooperatives) must participate in and successfully complete testing (as described in Section 23, Texas Test Plan Team – Retail Market Testing of the protocols) before starting operations with ERCOT. (See Qualification/Certification below.)
Rates that TSPs and DSPs must charge for services are set by the PUCT.
Register with ERCOT using the form below. Registration forms are also provided for metering.
TDSPs interested in competing in the retail market must be certified by ERCOT. Please read more about Texas Retail Market Testing and the latest test flight.
