Item 8.01. Other Events

In December 2012, Public Service Company of Colorado (PSCo), a Colorado corporation and a wholly owned subsidiary of Xcel Energy Inc., filed a multi-year request with the Colorado Public Utilities Commission (CPUC) to increase Colorado retail natural gas rates by $48.5 million in 2013 with subsequent step increases of $9.9 million in 2014 and $12.1 million in 2015. The request is based on a 2013 forecast test year, a 10.5 percent return on equity (ROE), a rate base of $1.3 billion and an equity ratio of 56 percent. PSCo is requesting an extension of its Pipeline System Integrity Adjustment (PSIA) rider mechanism to collect the costs associated with its pipeline integrity efforts, including accelerated system renewal projects. PSCo estimates that the PSIA will increase by $26.8 million in 2014 with a subsequent step increase of $24.7 million in 2015 in addition to the proposed changes in base rate revenue. In conjunction with the multi-year base rate step increases, PSCo is proposing a stay-out provision and an earnings test through the end of 2015 with a commitment to file a rate case to implement revised rates on Jan. 1, 2016.

In January 2013, the CPUC suspended the tariff filing and set the case for hearing. In order to accommodate the procedural schedule, rates will go into effect as filed on Aug. 10, 2013, subject to refund for the difference between the filed rates and the rates approved in the final CPUC order in the case.

The Office of Consumer Counsel (OCC) asked the CPUC to require PSCo to file a Historic Test Year (HTY) to aid parties in evaluating PSCo’s multi-year rate request. PSCo made that filing on Feb. 14, 2013.

On April 3, 2013, four parties filed answer testimony in the natural gas case. The CPUC Staff and OCC recommended changes to the level of integrity management costs moved from the PSIA rider to base rates. For clarity, PSCo will present base rate recommendations relative to deficiencies without the PSIA revenues to isolate the base rate impacts of the recommendations. PSCo’s 2013 deficiency based on a Forecasted Test Year (FTY) net of PSIA changes was $45 million for 2013 and the revenue deficiency was $28.3 million based on a HTY.

The CPUC Staff recommended a rate reduction of $14.4 million, based on a HTY, an ROE of 9 percent and an equity ratio of 52 percent and other adjustments. The OCC recommended a rate increase of $0.5 million based on a HTY, an ROE of 9 percent and equity ratio of 51.03 percent and other adjustments. No other intervenor made ROE recommendations or specific recommendations regarding the revenue deficiency. The major adjustments to the test year proposed by the Staff and OCC are presented below.

While the OCC did not recommend that the CPUC set rates using a FTY, they did calculate a revenue deficiency of $12.4 million for 2013. PSCo’s rebuttal testimony is due April 26, 2013 and the matter will be heard before an administrative law judge in May 2013.
