Rate Schedules & Tariff Analysis

SPS C&I tariffs combine a fixed service-availability charge, a low flat energy charge, and a seasonal demand charge that is the dominant cost driver for most commercial and industrial accounts. Summer demand charges (Jun-Sep) run materially higher than winter, and a fuel cost recovery factor and power-factor adjustment apply on top of the base rates.

Southwestern Public Service (Xcel Energy) Rate Schedule List

ScheduleApplicability
Secondary General ServiceC&I secondary voltage above 10 kW (Texas)
Primary General ServiceLarger C&I at primary voltage (Texas)
Small General ServiceSmall commercial low-demand (Texas)
Large General Service / Special ContractsVery large industrial loads (Texas)

Southwestern Public Service (Xcel Energy) Rate Features & TOU Details

  • Seasonal demand charges (summer Jun-Sep > winter Oct-May)
  • Voltage-differentiated rates (secondary vs primary) reward taking service at higher voltage
  • Fuel cost recovery factor applied per kWh (PUCT Sheet IV-69)
  • Power-factor adjustment for loads above 200 kW
  • Special contracts available for very large industrial loads

Limitations & Considerations

  • Third-party billing access still requires a signed customer data release form or Green Button authorization; there is no fully self-service third-party billing portal.
  • AMI / smart-meter deployment is still in progress, so 15-minute interval data is not yet available on every premise.
  • InfoWise enrollment and API onboarding take roughly 5-10 business days.
  • EDI is technically open to third parties but standard practice is for the customer to transmit their own EDI; Green Button or data release is preferred for consultants.

Southwestern Public Service (Xcel Energy) Data Access FAQ

How does a commercial customer get 15-minute interval data from SPS?

Submit the InfoWise (Empower Intelligence) interest form selecting the number of meters and a refresh tier (monthly, daily, or real-time). Xcel contacts you within 5-10 business days to enable web dashboard, CSV export, or API access. AMI-equipped premises can alternatively share interval data through Green Button Connect My Data.

Can an energy consultant pull our SPS data automatically?

Yes. The cleanest path is Green Button Connect My Data: the consultant registers as a Green Button Service Provider, you authorize them through your My Account portal, and they pull bill and 15-minute interval data via the OAuth/ESPI API. For one-time history, a signed data release form delivers CSV/Excel within 14 days.

Does SPS support EDI for invoices and payments?

Yes. Xcel Energy supports ANSI X12 EDI for SPS, including the 810 invoice and 820 payment order over SFTP or VAN. Complete the EDI Customer Information Form, select SPS as the operating company, and the Xcel EDI team provisions test then production credentials.

Is SPS service deregulated like the rest of Texas?

No. SPS operates outside ERCOT in the Southwest Power Pool, so there is no retail electric choice in its Texas Panhandle/South Plains and New Mexico territory. Rates are bundled and set by the PUCT (Texas) and NMPRC (New Mexico).

How much billing history can we download?

The My Account portal provides up to 24 months of billing history that C&I customers can view and download as PDF, plus usage exports. Longer histories can be requested through a formal data release.
