8-K: Xcel Energy Subsidiary SPS Advances Major Resource Plan with 3,121 MW Capacity Selection

Southwestern Public Service Company (SPS), a subsidiary of Xcel Energy Inc., has publicly filed its portfolio selection report with the New Mexico Public Regulation Commission, identifying 3,121 MW of accredited capacity resources to meet future energy demands.

Summary

• Southwestern Public Service Company (SPS), a wholly owned subsidiary of Xcel Energy, Inc., filed its Integrated Resource Plan (IRP) with the New Mexico Public Regulation Commission (NMPRC) in October 2023, which was accepted in February 2024.
• The IRP supports projected load growth and increasing reliability requirements, and secures replacement energy and capacity for retiring resources, projecting resource needs ranging from approximately 5,300 MW to 10,200 MW of nameplate capacity by 2030.
• In July 2024, SPS issued a Request for Proposal (RFP) seeking approximately 3,200 MW of accredited generation capacity by 2030.
• Bids from the RFP were received in January 2025.
• In July 2025, the portfolio selection report was publicly filed with the NMPRC, identifying 3,121 MW of accredited capacity resources.
• The selected resources include 1,273 MW of company-owned wind, 695 MW of company-owned solar, 1,112 MW of storage (472 MW company-owned, 640 MW via Power Purchase Agreements), and 2,088 MW of company-owned natural gas, totaling 5,168 MW of nameplate capacity.
• SPS expects to file Certificate of Convenience and Necessity (CCN) applications for these assets with the Public Utility Commission of Texas (PUCT) and NMPRC in the second half of 2025, with approvals anticipated in 2026.
• A second RFP will be issued to solicit a minimum of 500 MW of accredited capacity through 2032, including additional renewable generation for New Mexico Renewable Portfolio Standard compliance.

• Regulatory changes and/or limitations related to the use of natural gas as an energy source.
• Challenging labor market conditions and the ability to attract and retain a qualified workforce.
• Ability to execute on strategies or achieve expectations related to environmental, social, and governance matters, including as a result of evolving legal, regulatory, and other standards, processes, and assumptions, the pace of scientific and technological developments, increased costs, the availability of requisite financing, and changes in carbon markets.

Future Outlook

SPS expects to file Certificate of Convenience and Necessity (CCN) applications for the specific assets with the Public Utility Commission of Texas (PUCT) and New Mexico Public Regulation Commission (NMPRC) in the second half of 2025, with regulatory approvals anticipated in 2026. A second Request for Proposal (RFP) will be issued to solicit a minimum of 500 MW of accredited capacity through 2032, which will include additional renewable generation to ensure compliance with New Mexico Renewable Portfolio Standard requirements.

Industry Context

This filing reflects a common strategy among U.S. utilities to proactively address increasing electricity demand, replace retiring generation assets, and integrate a diverse energy mix, including significant renewable and storage components, while maintaining grid reliability. The inclusion of natural gas alongside renewables and storage indicates a balanced approach to energy transition, acknowledging the need for dispatchable capacity to support intermittent renewable sources. The multi-year planning and regulatory approval processes are typical for large-scale utility infrastructure projects, aligning with broader industry trends towards decarbonization and grid modernization.

Comparison to Industry Standards

• The resource plan's emphasis on a significant portion of wind (1,273 MW) and solar (695 MW) capacity aligns with the broader utility industry's accelerating transition towards renewable energy sources, driven by environmental goals and declining costs of these technologies.
• The substantial inclusion of battery storage (1,112 MW total) is consistent with leading utilities' efforts to enhance grid flexibility, integrate higher penetrations of intermittent renewables, and improve reliability, mirroring projects by companies like NextEra Energy and Duke Energy.
• The continued reliance on natural gas (2,088 MW) for a portion of the capacity reflects a common industry approach to ensure baseload power and grid stability, especially as coal plants retire, similar to strategies employed by utilities such as Southern Company and Dominion Energy, which balance gas with renewables.
• The long-term planning horizon (projected needs up to 2030 and a second RFP through 2032) is standard for large utility infrastructure development, comparable to integrated resource plans filed by major utilities across the U.S. like Pacific Gas and Electric (PG&E) or Arizona Public Service (APS).

Stakeholder Impact

• **Shareholders**: The successful progression of the resource plan could provide long-term stability and growth opportunities, potentially impacting future earnings and capital expenditures. The significant capital investment required for these projects may influence financial performance.
• **Customers**: The plan aims to support projected load growth and increase reliability, which should ensure continued access to electricity and potentially more diverse energy sources.
• **Employees**: The development and operation of new generation facilities may create new job opportunities or require retraining for existing staff.
• **Regulatory Authorities**: The filing and approval processes involve close collaboration with the NMPRC and PUCT, demonstrating compliance with regulatory requirements and contributing to energy policy objectives.
• **Suppliers/Contractors**: The large-scale projects will likely involve significant contracts for equipment, construction, and services, benefiting various suppliers and contractors in the energy sector.

Next Steps

• SPS expects to make Certificate of Convenience and Necessity (CCN) filings for the specific assets with the Public Utility Commission of Texas (PUCT) and New Mexico Public Regulation Commission (NMPRC) in the second half of 2025.
• Regulatory approvals for the selected assets are expected in 2026.
• SPS will issue a second Request for Proposal (RFP) to solicit a minimum of 500 MW of accredited capacity through 2032, including additional renewable generation for New Mexico Renewable Portfolio Standard compliance.
