What is the main purpose of this 8-K filing?

The main purpose of this 8-K filing is to inform investors about significant rate case filings and approvals by Xcel Energy's subsidiary, Northern States Power Company (NSP-Minnesota), in both Minnesota and North Dakota. It details the requested revenue increases, approved interim rates, and key financial parameters like the requested Return on Equity.

How much additional revenue is NSP-Minnesota seeking through these rate cases, and what has been approved so far?

In Minnesota, NSP-Minnesota initially sought an approximate $150 million annual revenue increase. The MPUC approved interim rates of $123 million, effective January 3, 2011. In North Dakota, NSP-Minnesota is seeking approximately $19.8 million in additional annual revenue and has requested interim rates of about $17.4 million, effective February 19, 2011.

What is the significance of the approved interim rates?

Interim rates allow the utility to begin collecting a portion of the requested higher rates while the regulatory commission reviews the full request. These rates are typically subject to refund, meaning the company may have to repay customers if the final approved rates are lower than the interim rates collected.

What factors influenced the MPUC's decision on the interim rates in Minnesota?

The MPUC approved interim rates of $123 million, which was $7 million less than initially requested. This reduction was attributed to changes in NSP-Minnesota’s capital structure to align with the final rate proposal and the approved sale of $17.3 million of transmission assets.
