Item 8.01. Other Events

On Nov. 14, 2008, Public Service Company of Colorado (PSCo), a Colorado Corporation, filed a request with the Colorado Public Utilities Commission (CPUC) to increase Colorado electric rates by $174.7 million annually, or approximately 7.4 percent. The rate filing is based on a 2009 forecast test year, an electric rate base of $4.2 billion, a requested ROE of 11.0 percent and an equity ratio of 58.08 percent.

On Feb. 13, 2009, parties filed answer testimony in the case.  The Colorado Public Utilities Commission Staff (CPUC Staff), accepted PSCo’s forecast test-year and recommended an increase of $110 million based on a 10.37 percent ROE.  The CPUC Staff also recommended that the increase be split in to two parts, the first part consisting of $69.9 million, effective in July 2009 and the remaining $40 million to take effect on or about Jan. 1, 2010 to coincide with the implementation of rates from the next rate case.  In addition to ROE, the primary CPUC Staff adjustments are related to the sales forecast, debt rate, incentive pay, and wage increases.  The CPUC Staff also recommends an earnings test to refund any earnings above authorized levels to customers.

The Office of Consumer Council (OCC), recommended a $3.8 million increase based on a historic test year increase of $69.9 million. The OCC recommended an ROE of 9.75 percent and an equity ratio of 53 percent.  The OCC recommended adjustments to the cash working capital and rate case expense.

Other parties filing testimony affecting the revenue requirements were the Colorado Energy Consumers which supported use of a historic test year; Ratepayers United of Colorado, which recommended a 9.5 percent ROE; and Leslie Glustrom, a citizen intervenor, who raised concerns about the Comanche 3 project as well as PSCo’s consulting and personal communication costs.

A final decision is expected in the summer of 2009.  The following procedural schedule has been established:

·PSCo rebuttal testimony on March 20, 2009;

·Staff and intervenor surrebuttal testimony on April 10, 2009; and

·The hearing on the merits is scheduled for April 20 - May 1, 2009.
