Wisconsin Electric and Natural Gas Rate Request
In March 2025, Northern States Power Company-Wisconsin (NSP-Wisconsin), a wholly owned subsidiary of Xcel Energy Inc., filed a request with the Public Service Commission of Wisconsin (PSCW) for a multi-year electric and natural gas rate increase.
For the electric utility, NSP-Wisconsin requested a total electric revenue increase of $94 million (11.8%) in 2026 and an incremental $57 million (7.1%) in 2027, for a total of $151 million over the two-year period of 2026 and 2027. The electric rate increase is based on electric rate base of $2.9 billion in 2026 and $3.2 billion in 2027. For the natural gas utility, NSP-Wisconsin requested a total natural gas revenue increase of $20 million (12.7%) in 2026 and an incremental $4 million (1.5%) in 2027, for a total of $24 million (14.2%) over the two-year period of 2026 and 2027. The natural gas rate increase is based on natural gas rate base of $0.3 billion in 2026 and $0.4 billion in 2027. Both the electric and natural gas rate requests are based on forward-looking test years, with a 10.0% return on equity (ROE) and an equity ratio of 53.5%.
On August 8, 2025, the PSCW Staff and intervenors filed their direct testimony. The PSCW Staff recommended an electric base rate increase of $115 million or 14.4% over the two-year period. The PSCW Staff additionally recommended a natural gas rate increase of $21 million, or 12.3% over the two-year period, all based on a ROE of 9.7% and an equity ratio of 53.5%.
Intervenors mainly limited their comments on revenue requirements to ROE focusing the majority of their testimony on cost of service, rate design and other policy issues. The major components of the PSCW Staff recommendation are summarized below:

(a)Capital investment adjustment includes $7 million associated with two MISO Long Range Transmission Plan (LRTP) projects that are pending PSCW approval (Grid Forward and Western Wisconsin Transmission Connection). It is PSCW Staff historic practice to recommend adjustments for projects until Commission approval is received. Approval of both LRTP projects is anticipated in the fourth quarter of 2025.
(b)Since filing the case, the Minnesota Public Utilities Commission authorized a reduction to the annual nuclear decommissioning accrual. This reduction, which flows to NSP-Wisconsin through the interchange agreement, reduced the NSP-Wisconsin rate request and is earnings neutral.
Key dates in the procedural schedule are as follows:
•Rebuttal testimony: August 28, 2025
•Hearing: Sept. 16, 2025
A PSCW decision is anticipated late fourth quarter 2025.
