In its Order 1000 compliance filing in October 2012, MISO proposed that all future reliability projects be fully allocated to the zones
in which the project is located (rather than allocating costs more broadly) while MVP projects would continue to be eligible for
regional cost allocation. FERC action is anticipated in 2013. The NSP System has certain new transmission facilities for which other
customers in MISO contribute to cost recovery. Likewise, the NSP System also pays a share of the costs of projects constructed by
other transmission owning entities. The transmission revenues received by the NSP System from MISO, and the transmission
charges paid to MISO, associated with projects subject to regional cost allocation could be significant in future periods.
RSG Charges — The MISO tariff charges certain market participants a real-time RSG charge, which is designed to ensure that any
generator scheduled or dispatched by MISO will receive no less than its offer price for start-up, no-load and incremental energy. In
August 2010, the FERC issued two orders relating to RSG charge exemptions and the allocation of the RSG costs among MISO
participants. In recent RSG filings, MISO has proposed, and the FERC has accepted, allocating a greater portion of the RSG costs
related to resources committed for voltage and local reliability requirements to the market participants with the loads that benefit
from such commitments. NSP-Minnesota is permitted to recover the RSG costs through FCA mechanisms approved by the
regulators in each jurisdiction. Certain of the FERC’s orders remain pending on rehearing, and appeals of the FERC orders to the
U.S. Court of Appeals for the D.C. Circuit have been held in abeyance, pending the FERC’s disposition of rehearing requests.
