, filed a Request for Reconsideration on a limited number of specific points within the Iowa Utilities Board's (IUB's) written decision order on IPL's 2009 test year electric rate case issued on January 10, 2011. The request asks the Board to clarify and/or provide further guidance on several discreet items in its order. The reconsideration request is not expected to result in a material change to the revenue requirements set by the IUB.
