2024 Minnesota Electric Rate Case
In November 2024, Northern States Power Company, a Minnesota corporation (NSP-Minnesota), and a wholly owned subsidiary of Xcel Energy Inc.filed an electric rate case in Minnesota, seeking a total revenue increase of $491 million (13.2%) over two years, based on a return on equity (ROE) of 10.3%, a 52.5% equity ratio and rate base of $13.2 billion in 2025 and $14 billion in 2026. NSP-Minnesota also requested interim rates of $224 million for 2025. In December 2024, the Minnesota Public Utilities Commission (MPUC) reduced the interim rate request for wildfire mitigation costs (as these costs were deemed as new costs not previously approved in a rate case) and approved interim rates of $192 million, effective January 1, 2025.
In March 2025, NSP-Minnesota filed supplemental direct testimony, updating its total revenue request to $473 million.
On August 22, 2025, eight parties filed testimony. The Minnesota Department of Commerce (DOC), Office of Attorney General (OAG), Xcel Large Industrial Customers (XLI), the Citizens Utility Board of Minnesota (CUB), Walmart and Joint Intervenors were the only parties to quantify recommended financial adjustments. XLI recommended $190 million in proposed adjustments, based on a reduced ROE and a reduction in certain O&M expenses. CUB recommended proposed adjustments based on a reduced ROE and elimination of reconnection and late fee revenues. Walmart recommended an adjustment based on a reduced ROE. Other parties provided issue specific recommendations.
Proposed DOC modifications to NSP-Minnesota's request are summarized below:
