Mirant begins commercial operation at second phase of Indiana power plant

ATLANTA, June 6, 2003 — Mirant announced that it began commercial operation on June 1 of the second phase of its Sugar Creek generating plant near Terre Haute, Ind. This phase of development converts the simple-cycle facility to a combined-cycle facility and adds 259 megawatts of generating capacity for a total of 559 megawatts.

“The completion of this project allows Mirant to compete in the Indiana and Midwest markets with environmentally advanced and highly cost-effective generating technology,” said Eddie Dorsett, vice president for Mirant’s Mid- Continent region. “The Midwest market is of strategic importance to Mirant, and participation there supports our goal to focus on well-functioning, regional markets where we have a critical mass of assets, people and customers.”

The first phase of the Sugar Creek power plant is a 300-megawatt generating facility that began commercial operation in July 2002.
