Item 8.01.  Other Events.

In February 2011, Southwestern Public Service Company (SPS), a New Mexico corporation, and a wholly owned subsidiary of Xcel Energy Inc., filed a request in New Mexico with the New Mexico Public Regulation Commission (NMPRC) seeking to increase New Mexico electric rates approximately $19.9 million. The rate filing was based on a 2011 test year adjusted for known and measurable changes for 2012, a requested return on equity (ROE) of 11.25 percent, an electric rate base of $390.3 million and an equity ratio of 51.11 percent.

On Sept. 12, 2011, the parties filed an unopposed black box settlement to resolve all issues in the case.  Under the settlement, base rates will increase by $13.5 million.  SPS has agreed not to file another base rate case until Dec. 3, 2012 with new final rates from the result of such case not going into effect until Jan. 1, 2014 (Settlement Period), provided however, that SPS can request to implement interim rates if the NMPRC standard for interim rates is met.  During the Settlement Period, rates are to remain fixed aside from the continued operation of the fuel adjustment clause and certain exceptions for energy efficiency, a rider for an approved renewable portfolio standard regulatory asset, and actual costs incurred for environmental regulations with an effective date after Dec. 31, 2010.  The NMPRC hearing for the settlement is set for Oct. 5-6, 2011.  It is expected that the NMPRC will issue a final order addressing the settlement in November or December of 2011 with final rates effective Jan. 1, 2012.

Factors that could cause actual results to differ materially include, but are not limited to: general economic conditions, including inflation rates, monetary fluctuations and their impact on capital expenditures and the ability of Xcel Energy and its subsidiaries to obtain financing on favorable terms; business conditions in the energy industry; including the risk of a slow down in the U.S. economy or delay in growth recovery; trade, fiscal, taxation and environmental policies in areas where Xcel Energy and NSP-Minnesota have a financial interest; customer business conditions; actions of credit rating agencies; competitive factors including the extent and timing of the entry of additional competition in the markets served by Xcel Energy and its subsidiaries; unusual weather; effects of geopolitical events, including war and acts of terrorism; state, federal and foreign legislative and regulatory initiatives that affect cost and investment recovery, have an impact on rates or have an impact on asset operation or ownership; or imposed environmental compliance conditions; structures that affect the speed and degree to which competition enters the electric and natural gas markets; costs and other effects of legal and administrative proceedings, settlements, investigations and claims; financial or regulatory accounting policies imposed by regulatory bodies; availability of cost of capital; employee work force factors; and the other risk factors listed from time to time by Xcel Energy and SPS in reports filed with the Securities and Exchange Commission (SEC), including Risk Factors in Item 1A and Exhibit 99.01 of Xcel Energy’s and SPS’s Annual Report on Form 10-K for the year ended Dec. 31, 2010 and Quarterly Report on Form 10-Q for the quarters ended March 31, 2011 and June 30, 2011.
