Planning for the Southwestern Public Service Company Transmission System (SPS)

For Texas and New Mexico

The planning process conducted by Xcel Energy subsidiary Southwestern Public Service Company (SPS) includes one or more annual open planning meetings that allow interested parties including customers, sponsors of transmission solutions, generation solutions and solutions utilizing demand response, interconnected transmission providers, state and local regulatory bodies and other stakeholders input into and participation in all stages of development of the SPS local transmission plan.

SPS participates in the SPP STEP regional process through the Integrated Planning Process (ITP) and encourages SPS transmission customers to participate in those regional planning processes.

The SPS transmission planning region is limited to SPS’s electrical system boundary.
