Item 8.01. Other Events.

On Nov. 22, 2011, Public Service Company of Colorado (PSCo), a Colorado Corporation and a wholly owned subsidiary of Xcel Energy Inc., filed a request with the Colorado Public Utilities Commission (CPUC) to increase Colorado retail electric rates by $141.9 million.  The request was based on a 2012 fully forecast test year, a 10.75 percent return on equity, a rate base of $5.4 billion and an equity ratio of 56 percent.  Final rates are expected to be effective in the summer of 2012.PSCo filed a petition on Nov. 23, 2011 to implement interim rates of $100 million to be effective in January 2012.

On Dec. 23, 2011, certain parties filed comments on the interim rate request petition.  The CPUC Staff’s primary recommendation is for the CPUC to reject the interim rate request stating that PSCo’s strong financial condition did not warrant such rate increase and that PSCo had not shown that the drivers of the revenue deficiency were extraordinary.  Alternatively, if the CPUC did decide to approve the interim rate increase, the CPUC Staff recommended that the increase be in the range of $45.3 million to $57.1 million rather than the $100 million requested by PSCo based on the changed jurisdictional allocators due to the expiration of a large wholesale contract and an increase in depreciation expense due to the growth in plant in service.  The Colorado Office of Consumer Counsel (OCC) also opposed the interim rate increase.  However, if interim rates are granted, the OCC proposed that the CPUC limit the interim rate increase to $11.2 million.  In addition, certain PSCo customers filed comments opposing the interim rate increase.  PSCo has an opportunity to provide reply comments by Jan. 5, 2012 and the CPUC decision on the petition is expected in January 2012.
