MGE files application for customer fuel credit


On March 31, 2006, Madison Gas and Electric Company (MGE) filed a second application with the Public Service Commission of Wisconsin (PSCW) requesting a fuel credit for its electric customers as a result of a continued decrease in its actual electric fuel costs when compared to those fuel costs projected in its most recent rate order.


Under the PSCW "fuel rules" that became effective January 1, 2006, MGE can apply for a fuel surcharge if actual electric fuel costs exceed 102% of the electric fuel costs allowed in its latest rate order. Conversely, MGE may have to provide a fuel credit to its customers if actual electric fuel costs are less than 99.5% of the electric fuel costs allowed in that rate order. Based on the results for the month ended February 28, 2006, MGE estimates that actual electric fuel costs will be less than that lower end for 2006. In its application to the PSCW, MGE proposes a fuel credit of $0.00096 per kilowatt-hour in addition to its current interim fuel credit. MGE estimates that this credit, if approved, could result in an additional reduction to 2006 electric revenues of approximately $2.5 million.


The current interim fuel credit reflects lower actual electric fuel costs for the month ended January 31, 2006, and was approved by the PSCW on March 9, 2006. It has resulted in a $0.00069 per kilowatt-hour reduction to electric rates and a projected $1.8 million reduction to 2006 electric revenues. This credit is being provided to customers via reduced electric rates. The reduction in electric rates was effective on the date of that order and is expected to continue through December 31, 2006.


The March 31, 2006, application and any resulting fuel credit are subject to approval by the PSCW.
