Summary
Xcel Energy's SPS subsidiary is encountering significant regulatory resistance in its New Mexico rate case. The company filed for a $168 million revenue increase in November 2025, but eight intervenors—including state regulators, the attorney general, and large customers—filed testimony on May 1, 2026 proposing dramatically lower increases ranging from just $28 million to $113 million.
The most contentious issues are the allowed return on equity (with proposals as low as 8.10% versus SPS's 10.5% request) and how costs should be allocated between New Mexico and other states where SPS operates. Retail investors should care because this rate case represents a material revenue opportunity that may fall significantly short of expectations.
A compromise outcome in the middle of the range would still mean tens of millions less in annual revenue than requested, directly impacting earnings from New Mexico operations. The most aggressive intervenor proposals would cut the revenue increase by more than 80%. Watch for SPS's rebuttal testimony due May 29, 2026, which will reveal how the company responds to these challenges and whether it adjusts its requests. The final decision in Q4 2026 will set rates for years to come and signal regulatory sentiment toward utility returns in New Mexico.

Jurisdictional allocators(57)— (2)—
NMPRC Staff proposes a reduction to the revenue request based on jurisdictional allocators, which determine how costs are assigned between New Mexico and other states where SPS operates. This is the single largest adjustment proposed by Staff and suggests disagreement over how much of SPS's costs should be recovered from New Mexico ratepayers versus customers in other jurisdictions.

In November 2025, Southwestern Public Service Company (SPS), a New Mexico corporation, and a wholly owned subsidiary of Xcel Energy Inc. filed an electric rate case with the New Mexico Public Regulation Commission (NMPRC) seeking a revenue increase of $168 million (16.0%) as updated in March 2026. The request is based on a future test year period ending Nov. 30, 2027, a return on equity (ROE) of 10.5%, an equity ratio of 56% and retail rate base of $3.9 billion.
SPS filed for a $168 million (16%) revenue increase in New Mexico based on a $3.9 billion rate base, 10.5% ROE, and 56% equity ratio. This represents a significant rate increase request that, if approved as filed, would materially boost revenues from New Mexico operations. The filing uses a future test year ending November 30, 2027, meaning rates would be set based on projected costs and investments.
