Item 8.01. Other Events

In December 2012, Southwestern Public Service Company (SPS), a New Mexico corporation, and a wholly owned subsidiary of Xcel Energy Inc., filed an electric rate case in New Mexico with the New Mexico Public Regulatory Commission (NMPRC) for an increase in annual revenue of approximately $45.9 million effective in 2014.  The rate filing is based on a 2014 forecast test year (FTY), a requested return on equity (ROE) of 10.65 percent, an electric rate base of $479.8 million and an equity ratio of 53.89 percent. In June 2013, SPS revised its requested rate increase to $43.3 million.

In August 2013, the NMPRC Staff, the New Mexico Attorney General, the Federal Executive Agencies, the Coalition of Clean Affordable Energy, Occidental Permian, Ltd. and New Mexico Gas Company filed testimony.

In September 2013, SPS filed rebuttal testimony, revising the total requested increase to $32.5 million, based on updated information and an ROE of 10.25 percent. This reflects a base and fuel increase of $20.9 million, an increase of rider revenue of $12.1 million, a decrease to other of $0.5 million and excludes a fuel clause adjustment credit for non-renewable energy costs of $2.3 million.

In January 2014, the hearing examiner released her recommended decision. The recommendation proposed an ROE of 9.73 percent, an equity ratio of 53.89 percent, a FTY with certain adjustments and excludes certain employee benefits and other costs. In February 2014, the hearing examiner released a supplemental recommended decision proposing the approval of the requested $12.1 million renewable energy rider revenue recovery.

In March 2014, the NMPRC issued a final order and approved an overall increase of approximately $33.1 million. The increase includes: an ROE of 9.96 percent, allowance of the prepaid pension asset in rate base of approximately $2.4 million, allowance of certain non-labor operating and maintenance escalations and recovery of approximately $18.1 million of renewable energy costs through rider revenue instead of base revenue. As a result of a change in the amount of fuel costs recovered through base rates, SPS will no longer be required to credit customers for $2.3 million through the fuel clause adjustment. Parties have until April 25, 2014 to request rehearing or to file an appeal.

The following table summarizes the NMPRC's approval from SPS’ revised request:
