Deregulation
On May 21, 1999, the Texas Legislature passed Senate Bill 7 (SB 7), which required the creation of a competitive retail electricity market. TXU Energy was one of the first certified retail electricity providers to begin offering service at market open in 2002. TXU Corporation’s three main entities during the first several years of deregulation were TXU Energy, a retail electricity provider (REP), TXU Electric Delivery, a transmission and distribution utility (TDU) and TXU Power, a wholesale electricity generation provider.
