LEXINGTON, Mass.--(BUSINESS WIRE)--March 5, 2003

Excelergy continues to deliver significant platform and architecture

enhancements from its aggressive multi-year R&D campaign

Excelergy(R) Corporation announced today it has released the latest version of its Excelergy BusinessRunner(TM) platform to manage the collaborative communications and information exchange requirements of its expanding global client base. Excelergy BusinessRunner is now deployed at leading energy/utility clients such as American Electric Power, Portland General Electric, Sempra Energy Solutions, Hydro One (Ontario), Gestore del Mercato Elettrico (GME, the Italian national power exchange operator), Energiedirect/Essent NV (The Netherlands) and Powercor and ETSA Utilities (Australia).

"Excelergy's substantial R&D effort continues to deliver significant functionality enhancements and increasingly rapid ROI for our growing number of global clients," said Bill Mahoney, president and CEO of Excelergy. "For example, one of our BusinessRunner clients--on the first day of market operations alone--processed 28,000 transactions with only one exception, a success rate of more than 99.99 percent. That same client now supports Excelergy's platform with less than one FTE (full-time equivalent), which means an extremely low cost of ownership, operation and maintenance. The platform and architecture enhancements included in the newest version of BusinessRunner only reinforce these business and operational benefits achieved by our clients."

Excelergy BusinessRunner automates market connectivity, data transaction exchange and customer switching processes across multiple markets for multiple commodities. Excelergy clients throughout the energy/utility value chain have deployed the platform to manage hundreds of thousands of transactions per day.

The expanded functionality and performance enhancements in Excelergy BusinessRunner 5.3 include:

-- Accelerated data processing and throughput at even the highest transaction volumes

-- Streamlined, 'smart' data archiving to facilitate transparency reporting and full audit trails

-- Integrated workflow utilizing WF-XML, the data transfer specification defined by the Workflow Management Coalition

-- Expanded multi-jurisdiction and internalization features to accelerate new market entry anywhere in the world

-- Enhanced exception management for improved error handling and resolution

-- Improved management of trading partners
