Summary
Summary of the 8-K filed August 11, 2025. Cited figures are marked; the original filing is the authoritative source.
Xcel Energy's utility subsidiary Northern States Power Company-Wisconsin (NSP-Wisconsin) disclosed in this 8-K (filed August 11, 2025) the status of its multi-year electric and natural gas rate case before the Public Service Commission of Wisconsin (PSCW).
Filed in March 2025, the request seeks a two-year electric revenue increase of $151 milliona (electric revenue up $94 million, or 11.8%, in 2026 and an incremental $57 million, or 7.1%, in 2027) and a natural gas increase of $24 million over 2026-2027. The filing assumes a 10.0% return on equity and a 53.5% equity ratio, with forward-looking test years. On August 8, 2025, PSCW Staff and intervenors filed direct testimony.
PSCW Staff recommended a materially smaller increase: $115 millionb (14.4%) for electric and $21 million (12.3%) for natural gas over the two-year period, based on a 9.7% ROE and the same 53.5% equity ratio. The largest reductions are capital investment adjustments ($15 million electric, partly tied to two pending MISO transmission projects expected to be approved in Q4 2025), a $7 million electric ROE adjustment, and $6 million of O&M reductions. A Minnesota commission decision lowering the nuclear decommissioning accrual also reduced the Wisconsin request, which the company describes as earnings neutral.
Intervenors focused mainly on cost of service, rate design, and policy rather than ROE. For investors, the key takeaways are the gap between the requested and recommended revenue increases (about $36 millionc on the electric side) and the ROE gap (10.0% requested versus 9.7% recommended).
The next steps are rebuttal testimony on August 28, 2025, a hearing on September 16, 2025, and a PSCW decision expected in late Q4 2025. The filing is a regulatory update rather than a financial result, and the final authorized outcome could land between the Staff and company positions.
02—Key points
Key Highlights
- NSP-Wisconsin requested a two-year electric revenue increase of $151 million (11.8% in 2026, plus an incremental 7.1% in 2027) and a natural gas increase of $24 million (14.2% combined) filed with the PSCW in March 2025.
- PSCW Staff recommended a smaller electric increase of $115 million (14.4%) and a natural gas increase of $21 million (12.3%), a reduction of roughly $36 million on electric and $3 million on gas versus the request.
- The primary gap is ROE: the company requested 10.0% versus 9.7% recommended by Staff, with both sides assuming a 53.5% equity ratio.
- Staff's recommended reductions include $15 million in electric capital investment adjustments (partly tied to two pending MISO LRTP transmission projects), a $7 million ROE adjustment, and $6 million in O&M cuts.
- A Minnesota commission decision reducing the nuclear decommissioning accrual lowered the Wisconsin request, which the company says is earnings neutral.
- Key procedural dates: rebuttal testimony August 28, 2025; hearing September 16, 2025; PSCW decision expected late Q4 2025.
- Intervenors largely focused on cost of service, rate design, and policy issues rather than contesting the revenue requirement, beyond ROE.
03—Questions
Frequently Asked Questions
How much rate increase did NSP-Wisconsin request, and what did PSCW Staff recommend?
NSP-Wisconsin requested $151 million in electric increases and $24 million in natural gas increases over 2026-2027. PSCW Staff recommended $115 million for electric (14.4%) and $21 million for natural gas (12.3%) over the same period.
Why is PSCW Staff recommending a lower increase?
The main drivers are capital investment adjustments ($15 million electric, including $7 million tied to two pending MISO transmission projects), a lower ROE (9.7% vs. 10.0%, a $7 million electric reduction), O&M expense cuts ($6 million electric), and a nuclear decommissioning accrual reduction ($6 million electric).
Will the MISO transmission projects affect the outcome?
Staff has excluded $7 million tied to the Grid Forward and Western Wisconsin Transmission Connection projects, as it customarily does until the Commission approves them. Approval is anticipated in Q4 2025, which could allow that amount to be recovered.
When will a final decision be made?
Rebuttal testimony is due August 28, 2025, and the hearing is scheduled for September 16, 2025. A PSCW decision is anticipated in late Q4 2025.
Is the nuclear decommissioning change material to NSP-Wisconsin's earnings?
No. The company states the reduction in the annual nuclear decommissioning accrual, which flows through the interchange agreement, lowered the rate request but is earnings neutral.
