the state of Texas. However, recently Entergy changed GSU's Texas name from Entergy Gulf States to Entergy Texas, Inc. and merged the GSU Louisiana service territory with its Entergy-Louisiana unit. Entergy Texas notified the Public Utility Commission of Texas that it would not be joining the Texas Interconnection operated by ERCOT, but would stay regulated and part of the massive Eastern Interconnection (one of the two major power grids in the US besides Texas' own which covers 75% of the state and has only DC Direct Current ties to other states). Only ONE time was the tie connection in Dayton, Texas between GSU/Entergy and the Texas Interconnection (via CenterPoint Energy) ever used; after Hurricane Ike to provide power to the water pumps along the north side of Lake Houston and other affected areas. This was done after Texas Governor Rick Perry ordered CenterPoint to request Entergy to close the tie. In 2013, Joe Domino was replaced by Sallie Rainer, which began the transition of Entergy Texas to The Woodlands.
