Enron explored trading markets beyond gas and electricity

Enron’s model was built around pricing and managing risk while connecting commodity producers with end users. It began in natural gas and expanded into electricity as that market started to deregulate; the account notes that oil had already been traded as a commodity for a long time.

The company also considered water, trucking and bandwidth as potential actively traded commodities. The assessment was that many of these markets could support an argument for trading, but Enron entered many of them too early, and they did not work out well.
