What was the net impact of the NSP-Minnesota rate case on Xcel Energy's revenue?

The NSP-Minnesota rate case resulted in a base rate increase of $12.8 million, which is lower than the initially requested $20.5 million. This, combined with the rate moratorium until January 2011 and customer sharing of earnings and margins, suggests a moderated revenue growth outlook from this subsidiary compared to what was initially sought.

Why was NSP-Wisconsin's rate increase request so significantly reduced?

The primary reason for the substantial reduction in NSP-Wisconsin's rate increase, from $47.1 million to $5.6 million, was the dramatic decline in market prices for fuel and purchased power. Other adjustments related to nuclear outage accounting and other factors also contributed to the decrease.

Will customers receive any refunds from these rate cases?

Yes, customers will receive refunds. NSP-Minnesota will refund an estimated $6.3 million in interim rates by June 1, 2009. For NSP-Wisconsin, a portion of a prior $8.3 million fuel surcharge refund liability will be offset by the new rate increase, and the remaining $2.7 million will be refunded in the first quarter of 2009.

What does the 'rate moratorium' for NSP-Minnesota mean for investors?

The rate moratorium means that NSP-Minnesota has agreed not to seek an increase in electric rates before January 1, 2011. This limits the potential for immediate revenue upside from this subsidiary for at least the next two years following this filing.
