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.

In addition, PSCo proposed transferring the revenue requirements from several riders to base rates, which will have no impact on the overall customer bills.  The amounts transferring from riders to base rates include $110.7 million of revenue requirements associated with the acquisition of the Rocky Mountain and Blue Spruce natural gas facilities currently recovered through the purchased capacity cost adjustment, $11 million from the transmission cost adjustment, and $17 million from the demand side management cost adjustment.

Combining these changes with the reduction from the Nov.1, 2011 filing for the purchased capacity cost adjustment results in an overall increase in customer bills of approximately 4 percent.

The primary drivers of the revenue deficiency are a change in the jurisdictional allocator between wholesale and retail jurisdictions due to the expiration of a large wholesale contract, increases in depreciation expense, including changes in depreciation rates, increases in property taxes, increases in distribution operating and maintenance costs, as well as increases in pension expense.

PSCo filed a motion on Nov. 23, 2011 to implement interim rates of $100 million to be effective in January 2012.
