Item 8.01. Other Events

On June 1, 2007, Northern States Power Company, a Wisconsin corporation and wholly owned subsidiary of Xcel Energy Inc. (NSP-Wisconsin) filed with the Public Service Commission of Wisconsin (PSCW) a request to increase retail electric rates by $67.4 million and retail natural gas rates by $5.3 million, representing overall increases of 14.3 percent and 3.3 percent, respectively. The request is based on a 2008 forecast test year. The filing assumes a common equity ratio of 53.86 percent, a return on equity of 11.00 percent and a combined electric and natural gas rate base of approximately $640 million.

On Oct. 15, 2007, the PSCW staff and interveners filed testimony in response to NSP-Wisconsin’s requested increase. The PSCW staff recommended an electric rate increase of approximately $44.1 million and a natural gas rate increase of $4.3 million, based on a return on equity of 10.75 percent and a common equity ratio of 53.58 percent. The PSCW staff testimony recommended adjustments that would decrease NSP-Wisconsin’s electric request by approximately $23.3 million. Approximately half of the PSCW staff’s adjustments are based on new or revised data since the filing was prepared.

The Wisconsin Industrial Energy Group (WIEG) and the Wisconsin Paper Council (WPC) also filed testimony in opposition to the rate increase on behalf of their members. WIEG proposed an electric rate increase of approximately $40.1 million, based on a 10.0 percent return on equity and a common equity ratio of 50.93 percent. WIEG disputed certain costs related to power production that are billed to NSP-Wisconsin through the interchange agreement with NSP-Minnesota, also a wholly owned subsidiary of Xcel Energy Inc. Specifically, WIEG contended that NSP-Minnesota nuclear decommissioning costs are overstated due to planned life extension at the Monticello and Prairie Island plants. WIEG was also disputing increasing costs associated with the Nuclear Management Company. Finally, WIEG contends fuel and purchased power costs were overstated because forced outage rates assumed for certain power plants are too high.

Additional staff and intervenor testimony on rate design issues was filed on Oct. 22, 2007, and all rebuttal testimony was filed on Oct. 29, 2007. Technical and public hearings were held on Nov. 8, 2007, and Nov. 12, 2007, respectively.

On Dec. 14, 2007, the commissioners of the PSCW voted with all but one of the PSCW Staff recommendations, which included:

· A 10.75 percent return on equity.

· Reducing the PSCW staff’s recommended common equity ratio from 53.58 percent to 52.5 percent.

· Approval of the recovery of all of NSP-Wisconsin’s deferred Midwest Independent Transmission System Operator, Inc. (MISO) Day 2 costs and deferred nuclear decommissioning costs.

· Allowed for a limited reopener for NSP-Wisconsin to propose recovery of production and transmission plant investment and associated operations and maintenance expenses as well as fuel costs for the year 2009.

As a result of the PSCW’s decisions, NSP-Wisconsin expects the final order will reflect an electric rate increase of approximately $39.4 million (8.1 percent) and a natural gas rate increase of $5.3 million (3.3 percent).

As noted above, a significant portion of PSCW staff’s adjustments were based on new or revised data since the filing was made, and will not have an earnings impact on NSP-Wisconsin. These adjustments, which total approximately $15 million, include: increased revenues due to a higher than projected sales forecast ($6 million); higher revenues associated with the interim fuel surcharge approved in October 2007 ($6 million); a lower forecast of fuel and purchased power costs than included in the original filing ($2 million); and a shift of DSM recovery from electric to gas operations ($1 million).

The PSCW rejected WIEG’s positions on nuclear decommissioning and NMC costs. The PSCW did make nuclear decommissioning costs subject to refund in the event that the Minnesota Public Utilities Commission (MPUC) reduces the 2008 accrual level as a result of the life extension at Monticello. There would be no earnings impact from this requirement if the MPUC decreases the decommissioning accrual. A written order is expected in the first week in January. New rates will be effective the day after the order is issued, or as soon thereafter as NSP-Wisconsin can implement.
