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.

To constitute a valid request, the request must contain the following:

  1. Desired in-service date of interconnection.

  2. Location of desired interconnection, which may include GPS coordinates, distances from known landmarks, distances from known transmission or distribution facilities in SPS area. The request must contain a defined point of interconnection, not just express a concept for an interconnection.

  3. Proposed MW load addition, over a 10-year period, with an initial load and forecast for the 10-year forward-looking period. Reactive power load will be assumed to be at 98 percent per the interconnection guidelines. If load is being shifted from other delivery points, adjusted forecasts for those delivery points must also be provided.

  4. Any special requirements, such as redundant transmission service, sensitive loads, special motor starting, any special process consideration.

  5. SPS contact for request. If request is for modification or a new wholesale PP delivery point, the SPP Attachment AQ forms should be completed and sent to SPP with a copy to Skip Black below. If it is a large retail general service request, contact the Director, Managed Retail Accounts, Bryan Kauffman, 806-378-2174.   One of his representatives will assist in preparing the necessary SPP Attachment AQ request forms for the study of the proposed delivery point modification or addition.
