retail energy services in Texas newly deregulated electricity market. On the wholesale side, Reliant owned, had an interest in, or leased 37 operating power generation facilities serving five regions of the United States. In January 2007, the Texas electricity market became fully deregulated, and Reliant began to offer an array of products, flexible service options, and pricing arrangements to a variety of customers. At this time, Reliant was the second largest mass market electricity provider in the state of Texas, with an annual revenue of $10.9 billion and more than 3,500 employees. In February 2007, Reliant Energy announced plans for Mark Jacobs, current chief financial operator, to succeed Joel Staff as chief executive officer and for Brian Landrum to become chief operating officer.
