The Energy Authority Manages Public Power Systems' Transition to Trading in Midwest Market Using nMarket™ Software

JACKSONVILLE, FL -- (MARKET WIRE) -- April 19, 2005 -- The Energy Authority Inc. recently managed three of its public power member systems' transition to trading wholesale energy in the new Midwest Independent System Operator (MISO) market with the help of The Structure Group's nMarket Midwest software. These systems include City Water Light and Power of Springfield, Ill. (CWLP); Columbia Water and Light of Columbia, Mo.; and the City of Fulton, Mo.

The Energy Authority® (TEA®) has provided wholesale energy trading and MISO market preparation services to CWLP since February 2003. Columbia joined in December of last year, and Fulton signed on just months ago.

"The nMarket Midwest software played a critical role in our being able to integrate these systems into our business processes," said Bill Clarke, RTO Implementation Manager for TEA. "Without The Structure Group, it would have been much more difficult to follow the evolution of the Midwest market and work to prepare three systems at the same time.

"We are now submitting bids and offers into the MISO market each day for each member for all load and all generation resources. This involves creating strategies, interacting with the MISO for the initial submittals for the day-ahead market, submitting real-time information to the reliability commitment program and then final submittal of real-time prices for the market tomorrow," Clarke added. "In addition, we are managing and scheduling long-term deals each day that were negotiated by the members before they joined with TEA."

The Structure Group, an international software and consulting company providing integrated solutions for the restructuring energy industry, has successfully partnered with 14 clients representing 46 market participants throughout the various market trials and testing phases to help them ready for the April 1 launch of the Midwest energy market.

"The partnership between Structure and TEA is a strong example of how companies work together to prepare for and anticipate change in a constantly restructuring market," Structure principal Lelon Winstead said. "TEA took a proactive approach to preparing for participation in the Midwest energy marketplace. Its clients are the beneficiaries of TEA's excellent planning."

Structure's software product -- nMarket Midwest -- offers effective communication with the region's market operator and reduced integration efforts so clients can focus on internal system integration and other areas of operation. Its automated functions are preferred over traditional manual methods and constantly adapt to changes in market rules. Structure has issued its fourth release of the software, all of which have supported trials and now the market go-live, reducing each client's investments in resources to keep up with the technology changes necessary to evolve with the market. nMarket fully supports the Midwest ISO's bid-based market and the estimation and verification of settlements.
