Item 8.01. Other Events

On Aug. 2, 2010, Northern States Power Company, a Wisconsin corporation and wholly owned subsidiary of Xcel Energy Inc, (NSP-Wisconsin) filed an application with the Public Service Commission of Wisconsin (PSCW) requesting to reopen the 2010 rate case and increase retail electric rates by $29.1 million, or 5.4 percent, based on a 2011 test year.  As part of the resolution of its 2010 electric rate case, the PSCW allowed NSP-Wisconsin to file an application to reopen the 2010 rate case for the limited purpose of updating electric rates for 2011 to reflect anticipated increases in fixed charges, fuel, and the pension-related components of the interchange agreement.

The requested increase in electric rates is primarily related to production and transmission fixed charges, specifically new investment in cleaner sources of energy and transmission lines to reliably meet customers’ electric needs as well as increasing costs for fuel and purchased power.  Partially offsetting these increased costs is a refund of the Wisconsin customers’ share of excess funds in the Monticello nuclear generating plant external decommissioning fund.  No changes are being requested to the capital structure or return on equity authorized by the PSCW in the 2010 base rate case.

The major cost components of the requested increase are summarized below:

NSP-Wisconsin has requested the PSCW to issue an order approving this application that will allow for new rates to be effective Jan. 1, 2011.  Public hearings to address NSP-Wisconsin’s rate request will be held later this fall at the PSCW.  No specific dates for hearings or prehearing conferences have been scheduled as of this time.
