Southern Company Implements aspenONE(TM) Performance Management Solution to Monitor Nuclear Plant Operations

Major US Utility Selects AspenTech and Its Partner, Queue Systems, to Implement an Integrated Asset Management Solution for Its Nuclear Power Subsidiary to Maintain Safe and Reliable Operations

CAMBRIDGE, Mass.--(BUSINESS WIRE)--Sept. 20, 2005-- Aspen Technology, Inc. (Nasdaq:AZPN) today announced that Southern Company (NYSE:SO), a major North American electrical utility, is implementing an integrated enterprise-wide Asset Management solution at its subsidiary Southern Nuclear Operating Company. This solution is based on the aspenONE(TM) Performance Management module, and will be deployed by AspenTech and its partner Queue Systems. The application, referred to by Southern Nuclear as the System and Component Engineering Interface (S&C-EI) Asset Management solution, will help the company significantly reduce maintenance costs and maintain safe, reliable and efficient operations at its power plants.

The integrated solution will allow authorized personnel to define and monitor the status of systems and components within the plants utilizing real-time operating data, maintenance data, defined maintenance plans and key performance indicators. The solution provides automatic user-specific notification when systems or components experience problems to enable systems users to manage and analyze performance data and improve equipment availability.

The aspenONE Performance Management module, which provides the foundation for the S&C-EI solution, features a number of Aspen Operations Manager applications including:

  • Role-Based Visualization - providing each authorized user with access to applications and information tailored to their specific job function
  • Event Management - enabling users to monitor operations, receive alerts and review suggested responses to unexpected events
  • Integration Infrastructure - integrating the required systems and applications within plant operations, including Southern Nuclear plant and corporate servers; using an integration platform based on a middleware message system to consistently deliver data to the applications that require it in a timely manner

"AspenTech's leading edge data historian and performance management tools will allow our project team to provide Southern Nuclear with a cost effective and technologically advanced solution which will meet its current and future needs," said Michael Bliss, President, Queue Systems. "Consolidating data into a single integrated system will provide significantly enhanced visibility for critical operating information."

"We are very pleased that Southern Nuclear has chosen AspenTech's performance management solution as the foundation for its integrated asset management project," said Blair Wheeler, Senior Vice President, AspenTech. "This significantly expands our successful relationship with Southern Company to include its nuclear subsidiary. We are also pleased to enhance our strong partnership with Queue Systems, which has delivered significant value to a wide range of customers in the process industries."

License revenue from this project was recognized in AspenTech's third fiscal quarter ending March 31, 2005.
