WASHINGTON -- The AOBA Alliance, Inc., announced that it has chosen Constellation NewEnergy, a subsidiary of Constellation Energy, as its new energy services supplier. The AOBA Alliance, Inc. has been assisting commercial customers in the District of Columbia, Maryland and Virginia in the procurement of competitive energy services since the deregulation of electricity markets approximately 10 years ago. Over the past decade AOBA Alliance participation has grown to roughly 650 megawatts of peak load and nearly 3.0 billion kilowatt-hours of annual electricity sales. Through this new relationship, the AOBA Alliance has the potential to become Constellation NewEnergy's largest retail customer and will provide an array of energy services to non-residential electricity and natural gas users throughout the metropolitan area.

"Our primary goal in negotiating with suppliers was of course, to obtain competitive pricing while maintaining the highly favorable contract terms and conditions that AOBA Alliance participants have enjoyed over the last decade," said Frann Francis, senior vice president and general counsel for AOBA. "Constellation NewEnergy clearly demonstrated that, with this new partnership, the AOBA Alliance will be positioned to offer additional services while enhancing its overall value to participants."

Constellation NewEnergy will provide AOBA Alliance participants with the ability to choose from a complete portfolio of energy services ranging from electricity and natural gas supply to renewable power solutions and energy efficiency programs.

"AOBA members can expect Constellation NewEnergy to be a committed energy services provider that will work to structure energy buying strategies to meet members' economic and sustainability goals," said Mark Huston, managing director of retail energy for Constellation Energy. "Most of all, Constellation NewEnergy will deliver the high level of customer service and streamlined energy procurement processes that AOBA Alliance participants expect."

AOBA Alliance participants will now have access to the resources and expertise of Constellation NewEnergy, a national leader in the provision of energy service for commercial customers. Constellation NewEnergy is active in all competitive markets in the U.S. and is the chosen supplier to two-thirds of the Fortune 100 businesses, including such energy service options as energy efficiency projects, installation of on-site solar generation, and participating in demand response programs that financially compensate businesses for reducing electricity usage during periods of peak demand on the grid.

The renewable energy products offered by Constellation NewEnergy through the AOBA Alliance program will provide businesses with simple, low cost ways of meeting their sustainability objectives, including using renewable energy certificates (RECs) to match electricity usage. Program participants can also utilize Constellation NewEnergy's comprehensive suite of Web-based tools (at www.newenergy.com) to help them manage costs, reduce overall power usage and access energy market updates.
