Indianapolis Power & Light Company Licenses Structure nMarket® Public Power

Structure's Bundled Application Suite Will Replace IPL Legacy Systems Supporting Transactions in Midwest ISO Power Markets

HOUSTON, TX--(Marketwire - November 21, 2007) - The Structure Group®, an industry leader in consulting and software for major energy market operators and participants, has announced that Indianapolis Power & Light Company (IPL) has licensed Structure nMarket® Public Power for transaction management and scheduling within the Midwest Independent System Operator (Midwest ISO) wholesale power market. IPL selected Structure nMarket Public Power for its ability to support its current and future market needs -- including future support for the new Midwest ISO Ancillary Services Market, and for the viability of Structure's methodology and approach to replacing IPL's legacy system.

IPL will use Structure nMarket Public Power to create and manage its daily offers and hourly updates of generation unit status to the Midwest ISO, to provide down-stream integration of Midwest ISO notifications and control area notifications with IPL's EMS system, and to create and manage Midwest ISO settlement statements and shadow settlement reports. Structure nMarket Public Power includes Structure's PositionManager™ application that IPL will utilize for deal capture and power scheduling.

"Replacing a legacy system is never easy, but the IPL and Structure teams developed a good integration plan and the nMarket Public Power deployment was relatively seamless," said Joe Bentley, Vice President at Indianapolis Power & Light Company. "Hats off to the Structure team who provided training across three shifts to ensure that we thoroughly understood the system and were ready for go-live."

"Indianapolis Power & Light Company is an important win for Structure and our nMarket application suite, as we continue to expand our product and consulting offerings in the Midwest ISO market," said Structure principal, Vikki Gates. "The IPL project team was a pleasure to work with, and we look forward to strengthening our relationship even more as the Midwest ISO gets ready to open its new Ancillary Services Market."
