Dynegy joins Tradespark electronic energy marketplace

HOUSTON, Texas, March 21, 2002 — Dynegy Inc. has become a partner in TradeSpark, L.P., a electronic marketplace for trading energy products. In conjunction with this expanded relationship, Dynegy has established an underlying electronic link between its proprietary eCommerce portal, Dynegydirect, and the neutral TradeSpark platform.

TradeSpark is a neutral, “many-to-many” energy marketplace, powered by eSpeed technology. There are currently 231 companies and more than 3,500 users participating in the TradeSpark marketplace. Dynegydirect offers customers real-time information and direct access to more than 750 Dynegy products in North America and Europe, including products not offered on other systems, such as hourly power backed by Dynegy’s own generating assets.

The expansion of our relationship with Dynegy demonstrates TradeSpark’s ability to attract industry leaders through the strength of our electronic platform and technological superiority.”

In 2001, TradeSpark added emissions, coal, off-peak power, hourly power and balance-of-the-day instruments. In 2002, the company plans to expand into the Canadian market, and will look to continue to add products that are actively traded and supported by market participants. In the next year, TradeSpark plans to expand the personalized trading functionality the system currently offers and to increase liquidity to the market by implementing rule-based trading systems.
