Ameren Corporation and its registrant subsidiary, Union Electric Company, doing

Missouri Public Service Commission (&#8220;MoPSC&#8221;) on January 27, 2009 approving an
increase for UE in annual revenues for electric service of approximately $162
million and UE&#8217;s implementation of a fuel and purchased power cost recovery

provides power to Noranda Aluminum, Inc.&#8217;s (&#8220;Noranda&#8221;) smelter&#160;plant in New
Madrid, Missouri. &#160;This plant has historically used approximately 4 million
megawatthours of power annually, making Noranda UE&#8217;s single largest customer and
constituting approximately 8% of UE&#8217;s total electric sales.</font></div>

result of a major winter ice storm in Southeastern Missouri on January 28, 2009,
Noranda&#8217;s smelter&#160;plant experienced a power outage related to non-UE owned
lines delivering power to the substation serving the plant.&#160;&#160;In a
January 29, 2009 press release, Noranda stated that the outage affected
approximately 75% of Noranda's&#160;New Madrid plant capacity. &#160;In
addition, Noranda stated that based on preliminary information and management&#8217;s
initial assessment, restoring full plant capacity may take up to 12 months, with
partial capacity phased in during the 12&#160;month period.</font></div>

extent UE&#8217;s sales to Noranda are reduced, generation made available could be
sold as off-system sales, likely at prices in excess of tariff prices received
from Noranda, assuming current market conditions. &#160;However, the fuel and
purchased power cost recovery mechanism approved by the MoPSC in its January
2009 electric rate order, which is expected to become effective on March 1,
2009, would require UE to flow substantially all of the off-system sales
revenues to customers. If this were to occur, and the Noranda smelter&#160;plant
operates at 25% capacity for 12 months, UE estimates its margins&#160;during
such period would be reduced by up to approximately
$73&#160;million.</font></div>

to adjust the fuel and purchased power cost recovery mechanism for this
unanticipated event, UE sought rehearing&#160;by the MoPSC of its January 2009
electric rate order on February 5, 2009 to allow UE to first recover from the
off-system sales any revenues it would lose as a result of the reduced tariff
sales to Noranda with any excess revenues collected being provided to customers
through the fuel and purchased power cost recovery mechanism.&#160;&#160;We are
unable to predict when or how the MoPSC may rule on this request or the ultimate
impact on Ameren and UE of the Noranda smelter plant power outage.</font></div>

ITEM
8.01  Other Events.
Reference
is made to the Current Report on Form 8-K dated January 28, 2009, of registrant
Ameren Corporation and its registrant subsidiary, Union Electric Company, doing
business as AmerenUE ("UE"), for a discussion of the order issued by the
Missouri Public Service Commission ("MoPSC") on January 27, 2009 approving an
increase for UE in annual revenues for electric service of approximately $162
million and UE's implementation of a fuel and purchased power cost recovery
mechanism, among other things.
UE
provides power to Noranda Aluminum, Inc.'s ("Noranda") smelter plant in New
Madrid, Missouri.  This plant has historically used approximately 4 million
megawatthours of power annually, making Noranda UE's single largest customer and
constituting approximately 8% of UE's total electric sales.
As a
result of a major winter ice storm in Southeastern Missouri on January 28, 2009,
Noranda's smelter plant experienced a power outage related to non-UE owned
lines delivering power to the substation serving the plant.  In a
January 29, 2009 press release, Noranda stated that the outage affected
approximately 75% of Noranda's New Madrid plant capacity.  In
addition, Noranda stated that based on preliminary information and management's
initial assessment, restoring full plant capacity may take up to 12 months, with
partial capacity phased in during the 12 month period.
To the
extent UE's sales to Noranda are reduced, generation made available could be
sold as off-system sales, likely at prices in excess of tariff prices received
from Noranda, assuming current market conditions.  However, the fuel and
purchased power cost recovery mechanism approved by the MoPSC in its January
2009 electric rate order, which is expected to become effective on March 1,
2009, would require UE to flow substantially all of the off-system sales
revenues to customers. If this were to occur, and the Noranda smelter plant
operates at 25% capacity for 12 months, UE estimates its margins during
such period would be reduced by up to approximately
$73 million.
In order
to adjust the fuel and purchased power cost recovery mechanism for this
unanticipated event, UE sought rehearing by the MoPSC of its January 2009
electric rate order on February 5, 2009 to allow UE to first recover from the
off-system sales any revenues it would lose as a result of the reduced tariff
sales to Noranda with any excess revenues collected being provided to customers
through the fuel and purchased power cost recovery mechanism.  We are
unable to predict when or how the MoPSC may rule on this request or the ultimate
impact on Ameren and UE of the Noranda smelter plant power outage.
