Summary
Xcel Energy's subsidiary, Northern States Power Company Minnesota (NSP-Minnesota), has filed a comprehensive two-year electric rate case with the Minnesota Public Utilities Commission (MPUC) on November 4, 2013. This filing seeks an overall increase in annual revenues of approximately $193 million (6.9%) for 2014 and an additional $98 million (3.5%) for 2015. The proposed increases aim to cover rising costs related to carbon-free generation, investments in a diverse energy supply, and essential reliability infrastructure for transmission and distribution systems. A key component of this filing is a rate moderation plan designed to soften the immediate impact on customer bills. This plan involves accelerating the amortization of a theoretical depreciation reserve and utilizing expected funds from the Department of Energy (DOE) to offset a portion of the requested increase. Despite these moderation efforts, customers can expect an approximate 4.6% increase in their bills for 2014 and an additional 5.6% in 2015, following interim rate adjustments.
