(a)	Includes payments required by PPAs for capacity rights and minimum quantities of MWhs required to be purchased. Refer to Note 21 for additional information on purchased power transactions.

(b)	IPL is obligated to pay for capacity and energy delivered under the DAEC PPA. If energy delivered under the DAEC PPA is less than the targeted energy amount, an adjustment payment is made to IPL, which is reflected in IPL's energy adjustment clause.

(c)

IPL and WPL enter into coal transportation contracts that are directly assigned to their specific generating stations, the amounts of which are included in Alliant Energy's, IPL's and WPL's tables above. Also included in Alliant Energy's and IPL's tables is IPL's respective portion of coal and coal transportation contracts related to jointly-owned generating stations not operated by IPL. In addition, Corporate Services entered into system-wide coal contracts on behalf of IPL and WPL of $88 million for 2012 and $62 million for 2013 to allow flexibility for the changing needs of the quantity of coal consumed by each. Coal contract quantities are allocated to specific IPL or WPL generating stations at or before the time of delivery based on various factors including projected heat input requirements, combustion compatibility and efficiency. These system-wide coal contracts have not been directly assigned to IPL and WPL since the specific needs of each utility were not yet known as of Dec. 31, 2011 and therefore are excluded from IPL's and WPL's tables above.

(d)	Refer to Note 1(b) for discussion of $34 million of charges recognized by Alliant Energy and IPL in 2011 for IPL's forward contracts to purchase SO2 emission allowances.

(e)	Includes individual commitments incurred during the normal course of business that exceeded $1 million at Dec. 31, 2011.
