The reason described in reasonable detail in Part III of this form could not be eliminated without unreasonable effort or expense
The subject annual report, semi-annual report, transition report on Form 10-K, Form 20-F, Form 11-K, Form N-SAR or Form N-CSR, or portion thereof, will be filed on or before the fifteenth calendar day following the prescribed due date; or the subject quarterly report or transition report on Form 10-Q or subject distribution report on Form 10-D, or portion thereof, will be filed on or before the fifth calendar day following the prescribed due date; and

State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-SAR, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.
The form 11-K, which is the subject of this Form 12b-25 extension, is being filed in order to report the information required of the Nuclear Management Company, LLC NMC Savings and Retirement Plan (the “Plan”). The Plan is unable to file timely its Form 11-K within the prescribed time period without unreasonable effort or expense. The Plan was amended effective January 1, 2013 to permit participants to elect to invest in the Xcel Energy Common Stock Fund and as such this is the first year that the Plan is filing a Form 11-K. The Plan is unable to timely file its Form 11-K because the preparation and audit of the financial statements of the Plan is still in process.  We will file the Form 11-K on or before the fifteenth calendar day following the prescribed due date.
