Aquila, Engage to Participate On Socalgas' Energy Marketplace Web Site.

LOS ANGELES--(BUSINESS WIRE)--Aug. 6, 1999--

Southern California Gas Co. (SoCalGas) has announced that two of the nation's 10 largest gas marketers -- Aquila Energy and Engage Energy US, L.P. -- have signed agreements with SoCalGas to participate as marketers on the utility's Energy Marketplace Web site.

Energy Marketplace (www.energymarketplace.com), launched in November 1997, is the nation's first Internet-based retail shopping center for energy. Energy Marketplace provides customers with free real-time access to comparative information on energy service providers, electric and natural gas prices and other energy information.

Energy Marketplace features a request for proposal (RFP) function that enables customers to secure price quotes from independent energy suppliers based on the customers' specific consumption profile and price preferences.

With the addition of Aquila and Engage, Energy Marketplace now hosts 16 marketers serving natural gas and/or electric customers in California on its site. Energy Marketplace has received national recognition from Sun Microsystems and various Internet publications for its innovative use of technology to foster customer choice programs.

"Aquila and Engage are among the top 10 gas marketers in the nation, and we're pleased to have them join us as we continue to expand the site," said Lee Stewart, president of Energy Transportation Services at SoCalGas. "Their participation broadens the energy service offerings available to our customers over the Internet."

"We look forward to exploring additional avenues to markets in California and other geographic areas as Energy Marketplace expands," said Richard McElroy, vice president of marketing for Engage.

For a small fee, marketers can participate as suppliers on the system and receive pricing requests from customers. Marketers can also use Energy Marketplace to display detailed information on their companies and service offerings.
