TradeSpark is an energy brokerage consortium of Cantor Fitzgerald, Dynegy, Coral Petroleum, Williams, Virginia Power and TXU. Prior to 9/11, TradeSpark had a small office in Houston and its primary location in New York City. Not only was a decision made to expand locally, but also to split operations to reduce risk in lieu of re-establishing the Cantor Fitzgerald office in New York City.
