RELIANT ENERGY TO ENTER DELAWARE ELECTRIC MARKET.

Reliant Energy, Houston, one of the country's leading competitive power providers, has announced plans to begin serving a broad class of commercial, industrial and institutional customers in the Delmarva utility district in Delaware. This marks the first time Reliant has entered the Delaware electric market.

On April 3, the Delaware Public Service Commission granted Reliant Energy Solutions East, LLC, a wholly owned subsidiary of Reliant Energy Inc., a license to serve these customers. The company's combination of competitive pricing, reliable service, customer support and flexible service options brings new choices to business customers in the state.

"We are committed to bringing the benefits of competitive markets to our customers and are pleased to be able to offer commercial and industrial customers in Delaware new options," said Jim Ajello, senior vice president, C&I business development. "Earlier this year, we announced plans to expand service into at least two new markets in 2007, and this brings us one step closer to achieving that objective."

The move builds on our extensive retail experience in ERCOT and broadens and strengthens our existing footprint in the PJM (Pennsylvania, New Jersey, Maryland) Interconnection. Reliant's Delaware license will enable it to serve the vast majority of Delaware's industrial customers representing a total market of 950 megawatts of load. Customers seeking additional information about products and services can contact Reliant at 443-423-1813.

Reliant will be positioned to put our knowledge and commitment to service to work for customers in these markets."
