LEXINGTON, MA., October 12, 2000 - Excelergy Corporation today announced it has become a sponsor of the Organization for the Advancement of Structured Information Standards (OASIS) to help promote the industry-wide acceptance of XML standards for open electronic data exchange among retail energy companies. Excelergy, a provider of e-infrastructure technology to the restructuring energy marketplace, first proposed a set of XML (eXtensible Markup Language) standards for the retail energy industry in October 1999 called Partner Interface Processes for Energy, or PIPE.

"The Internet is becoming the primary means of business-to-business communication in the retail energy industry, and XML in particular is emerging as the key to open, efficient web-based data transactions," said Chris Cazer, vice president of development and chief technology officer at Excelergy. "Excelergy is committed to collaborating with OASIS and other industry participants in the effort to standardize electronic communications within the retail energy marketplace."

By publishing PIPE and supporting OASIS, Excelergy opens the door to industry discussion about the most efficient ways for retail energy companies to communicate electronically via the Internet. In the absence of universally accepted standards, utilities and energy companies all along the generation, transmission and distribution chain have been forced to manage widely varying forms of business-to-business data exchange, leading to inefficiencies, errors and higher transaction costs.

"We're enthusiastic about Excelergy's participation in OASIS," said Laura Walker, executive director of OASIS. "Excelergy's expertise in web-based data exchange in the energy marketplace, and their contributions and input, will help OASIS promote the adoption of XML standards in the retail energy industry."

Excelergy created its core products - billing and customer care software and trading partner data transaction management software - with energy industry restructuring in mind. While its software supports the EDI-based standards already in place in a number of markets today, it is designed to fully leverage the emerging trend of using XML as the standard protocol for electronic data exchange. Sharing its knowledge and expertise in promoting efficient standards in the retail energy market, Excelergy will also benefit from OASIS' experience in advancing the acceptance and use of XML in other industries.
