NSP-Minnesota plans to address recovery of incurred costs in the next rate case for each of the NSP-Minnesota jurisdictions and
to file a request with the FERC for approval to recover a portion of the costs from NSP-Wisconsin through the Interchange
Agreement. NSP-Wisconsin plans to seek cost recovery in a future rate case. Based on the outcome of the MPUC decision, EPU
costs incurred to date were compared to the discounted value of the estimated future rate recovery based on past jurisdictional
precedent, resulting in a $10.1 million pretax charge in December 2012 which is included in O&M expense.
Monticello Nuclear Plant EPU — In 2008, NSP-Minnesota filed for both state and federal approvals of an EPU of approximately
71 MW for NSP-Minnesota’s Monticello nuclear generating plant. The MPUC approved the CON for the EPU in 2008. The
license amendment filing was placed on hold by the NRC Staff to address concerns raised by the Advisory Committee on Reactor
Safeguards related to containment pressure associated with pump performance. In September 2012, NSP-Minnesota made a
supplemental filing to the NRC to address the containment accident pressure concern, as part of its application to amend the
operating license to allow the power uprate. NSP-Minnesota expects to receive approval of the EPU project by the NRC in the
second half of 2013. NSP-Minnesota is planning to complete implementation of the equipment changes needed to support the
Monticello life extension and EPU projects in the planned spring 2013 refueling outage.
Overall, NSP-Minnesota is nearing completion of its life cycle management and EPU project at the Monticello nuclear generating
plant to help ensure continued safe and reliable operation through 2030, and to provide additional capacity of approximately 71
MW. As a result of the licensing delays discussed above, as well as engineering design changes and emergent work discovered
during implementation, both the cost and the projected in-service date exceed initial estimates, consistent with experience of other
nuclear plant life extension and uprate projects. In addition, despite the cancellation of the EPU project at the Prairie Island
nuclear generating plant, NSP-Minnesota is implementing life cycle management improvements at the Prairie Island facilities to
help ensure their safe and reliable operation through 2034. The major capital investments for these activities at the Monticello and
Prairie Island nuclear generating plants are expected to be completed in the years 2013 through 2017, with combined forecasted
capital costs in that period of approximately $500 million.

(a) This category includes wind energy de-bundled from RECs and also includes Windsource RECs. The NSP System uses RECs to meet or exceed state
resource requirements and may sell surplus RECs.
(b) Includes energy from other sources, including solar, biomass, oil and refuse. Distributed generation from the Solar*Rewards program is not included.
