01—Abstract
Summary
Summary of the 8-K filed May 5, 2026. Cited figures are marked; the original filing is the authoritative source.
Xcel Energy Inc. subsidiary Southwestern Public Service Company (SPS) is undergoing a rate case in New Mexico.
SPS initially requested a $168 milliona (16.0%) increase in electric rates, based on a future test year ending November 30, 2027, and proposing a 10.5% return on equity (ROE). However, on May 1, 2026, several intervenors, including the NMPRC Staff and New Mexico Department of Justice, filed testimony that significantly reduces the requested revenue adjustment. The intervenors' proposed adjustments, which focus on factors like jurisdictional allocators, ROE, capital structure, and purchased power costs, suggest a much lower total proposed revenue change ranging from $48 million to $113 million.
The NMPRC Staff, in particular, recommends a revenue change of $48 millionb and a lower ROE of 9.75%. The procedural schedule includes rebuttal testimony by May 29, 2026, a hearing in July 2026, and an anticipated NMPRC decision in the fourth quarter of 2026, with final rates likely implemented around November 30, 2026, if approved.

Frequently Asked Questions
What is the main purpose of this 8-K filing?
This 8-K filing provides an update on the ongoing electric rate case initiated by Xcel Energy's subsidiary, Southwestern Public Service Company (SPS), with the New Mexico Public Regulation Commission (NMPRC). It details the testimony filed by intervenors, which proposes significant adjustments to SPS's original rate increase request.
How does the intervenors' testimony differ from SPS's original request?
SPS originally requested a $168 million revenue increase. However, the testimony filed by intervenors suggests a much lower revenue change, with the NMPRC Staff recommending an increase of only $48 million. This reduction is due to proposed adjustments in areas like return on equity (ROE), capital structure, and purchased power costs.
When can investors expect a decision on the rate case?
The NMPRC is expected to issue a decision and implement final rates in the fourth quarter of 2026. The procedural schedule includes rebuttal testimony by May 29, 2026, and a hearing on July 7, 2026. The end of the rate suspension period is November 30, 2026.
What are the potential risks for Xcel Energy from this rate case?
The primary risk is that the NMPRC approves a revenue increase significantly lower than what SPS requested, or potentially even denies an increase, which would negatively impact SPS's earnings and Xcel Energy's overall financial performance. The specific ROE and capital structure approved by regulators are also key factors influencing profitability.
