Item 8.01. Other Events

2006 General Rate Case

Northern States Power Company, a Wisconsin corporation, (NSP-Wisconsin) filed an electric and natural gas rate case, as amended on Sept. 28, 2005, to reflect higher energy costs.  The amended filing requested an electric revenue increase of $53.1 million, or 13.4 percent, and a natural gas revenue increase of $7.7 million, or 4.8 percent, based on an 11.9 percent return on equity and a 56.32 percent common equity to total capitalization ratio.  On October 12, 2005, the staff of the Public Service Commission of Wisconsin (PSCW) filed testimony regarding the electric and natural gas increase request.  The staff testimony indicated that NSP-Wisconsin has a 2006 test year electric revenue deficiency of $45.4 million, or 11.4 percent, and a natural gas revenue deficiency of $5.8 million, or 3.5 percent, based on an 11.0 percent return on equity and a 56.43 percent common equity to total capitalization ratio.

Intervenor testimony was also filed on October 12, 2005.  Consultants representing the industrial intervenor group advocated a return on equity of 10.5 percent and a common equity to total capitalization ratio of 51 percent, as well as modifications to NSP-Wisconsin’s class cost of service study and rate design that would benefit their clients.  Testimony submitted on behalf of the U.S. Department of Defense and all other federal executive agencies advocated a 10.25 percent return on equity and a common equity to total capitalization ratio of 56.3 percent, as well as cost allocations and rate design to benefit the Fort McCoy military installation.

Both the staff of the PSCW and the industrial intervenor group suggested that the PSCW consider whether it should continue to authorize a common equity to total capitalization ratio and return on equity comparable to other A or AA rated Wisconsin utilities or use metrics appropriate to a BBB+ credit rating.

Hearings are scheduled to begin on Nov. 1, 2005.
