SPP Membership

SPP provides members of its regional transmission organization a broad and valuable portfolio of services including reliability coordination, market administration, coordination of transmission planning and more. Many of those services are also available to nonmembers on a contract basis.

RTO West

In July 2021, Southwest Power Pool’s board of directors and Strategic Planning Committee approved the submitted policy-level terms and conditions for regional transmission organization (RTO) expansion in the Western Interconnection. A November 2020 SPP Brattle study found that the move would be mutually beneficial and produce $49 million a year in savings. SPP anticipates its wholesale electricity market, resource adequacy program and other regionalized services can help western members achieve renewable-energy goals, reinforce system reliability and leverage new opportunities to buy, sell and trade power. Subsequent studies will yield further insight into the potential benefits for all involved parties. 

Western Resource Adequacy Program (WRAP)

The WRAP seeks to enhance and increase reliability for entities across its western footprint while maintaining existing responsibilities for reliable operations and observing existing frameworks for planning, purchasing and delivering energy. In 2021, WRAP chose SPP to serve as the program operator, performing forward showing and operations program functions, modeling and system analytics, real-time operations, continual technical improvement and IT systems work.

Contract Services

Western Energy Services

SPP’s Western Energy Services is a family of contract-based products offered to utilities in the Western Interconnection. They include:

  • Markets+: SPP is working with western utilities to develop a market offering that centralizes day-ahead and real-time unit commitment, provides hurdle-free transmission service across its footprint and paves the way for the reliable integration of renewables.
  • The Western Energy Imbalance Service Market (WEIS): Launched in 2021, the WEIS is a real-time wholesale electricity market that balances generation and load regionally, delivery cost savings and enhanced reliability to participants. 
  • Western Reliability Coordination (RC) Service: In 2019, SPP began operating in the Western Interconnection as a North American Electric Reliability Corporation (NERC) certified reliability coordinator, working with customers to keep the lights on and mitigate operational contingencies that threaten the reliability of the bulk power system. 
  • Western Interconnection Unscheduled Flow Mitigation Plan (WIUFMP): SPP administers the WIUFMP on behalf of several western utilities, a blueprint for the use of certain controllable devices in the mitigation of congestion along transmission lines in the west.

If you’re interested in discussing any of these services, including membership in the SPP RTO, please contact a customer relations representative to learn more.
