Item 8.01. Other Events

On June 12, 2008, Southwestern Public Service Company (SPS), a wholly owned subsidiary of Xcel Energy Inc., filed with the Public Utility Commission of Texas (PUCT), and the 80 cities in SPS' Texas service territory with original rate jurisdiction, a request for a Texas system retail electric general rate increase.

The filing requests an overall increase in annual revenues of approximately $61.3 million, or an increase of 5.9 percent. Base revenues are proposed to increase by $94.4 million, while fuel and purchased power revenue will decline by $33.1 million, primarily due to fuel savings from the Lea Power Partners, LLC (LPP) project. The LPP generating facility is located outside of Hobbs, New Mexico.

The rate filing is based on a 2007 calendar year base period adjusted for known and measurable changes and includes a requested rate of return on equity of 11.25 percent, an electric net rate base of approximately $989.4 million allocated to the Texas retail jurisdiction, and an equity ratio of 51.0 percent.

In SPS' last Texas rate case, the parties agreed that SPS seek, in this rate filing, interim rate relief of $18 million per year for the LPP power purchase agreement. The interim rates are proposed to go into effect when the LPP power plant comes on line in 2008. The jurisdictional deadline for the PUCT to act on SPS' request is Dec. 14, 2008.

The filing with the PUCT also includes a request to reconcile SPS' fuel and purchased power costs for calendar years 2006 and 2007. As of Dec. 31, 2007, SPS had a fuel cost under-recovery balance of approximately $50.6 million.
