Corporation and Interstate Power and Light Company (Alliant Energy&#146;s Iowa utility) will attend an investor conference. The following regulatory update is being provided in connection with that conference. </P>
<P STYLE="margin-top:24pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman" ALIGN="center"><B>Alliant Energy provides update on Marshalltown Generation Station (MGS) activities and transmission </B></P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">As previously announced, Iowa Utilities Board (IUB) Chair Jacobs, as presiding officer for the MGS administrative hearing, issued the Proposed Decision and
Order on November&nbsp;9, 2013 and Alliant Energy&#146;s Iowa utility accepted such order on November&nbsp;19, 2013. The order provides a cost cap for the project of $920 million, including the facility, transmission costs, owners&#146; costs and
AFUDC. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">On December&nbsp;9, 2013 Chair Jacobs issued an Order Clarifying Decision, in response to an intervener&#146;s request for clarification, stating
that all costs related to the transmission construction and reimbursements, including any potential tax gross up payments, are included in the $920 million cost cap. The clarifying decision also stated the cost cap is not reduced if Alliant
Energy&#146;s Iowa utility receives reimbursement for MGS transmission costs. However, refunds or reimbursements from other interconnecting generators received by Alliant Energy&#146;s Iowa utility for any MGS transmission upgrade costs would be
returned to ratepayers in a manner to be determined by the IUB. According to the clarifying decision, all transmission network upgrade costs, including amounts for which Alliant Energy&#146;s Iowa utility might be reimbursed, are included in the
overall cost cap. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Alliant Energy&#146;s Iowa utility expected to fund capital transmission upgrades for MGS based on the July 2013 FERC Attachment FF
decision (Docket No. EL12-104-000) and assumed such upgrades in its capital expenditure guidance issued on November&nbsp;7, 2013. Alliant Energy&#146;s Iowa utility has been informally notified that ITC Midwest LLC (ITC-M) intends to pursue an
option under the terms of the MISO Generator Interconnection Procedures to self-fund the transmission upgrades associated with MGS. Under this option, Alliant Energy&#146;s Iowa utility anticipates a direct assignment facility expense for the
network upgrades after the upgrades are placed into service. Alliant Energy&#146;s Iowa utility does not believe that the cost cap included in the Proposed Decision and Order would be affected if ITC-M were to ultimately self-fund the transmission
upgrade. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The IUB&#146;s overall approval of MGS is conditional upon attaining other permitting approvals necessary to construct and operate the MGS. One
required approval is IUB approval of construction of the gas pipeline necessary to service the facility. Recently, Alliant Energy&#146;s Iowa utility received final approval of the needed gas pipeline construction. Pending all additional regulatory
approvals, IPL expects to begin construction on MGS in 2014 and begin operations in 2017. </P>
