About Centerpoint Energy Plaza
CenterPoint Energy Plaza (formerly Houston Industries Plaza) is a 741 ft (226 m) building in downtown Houston. The original building, finished in 1974, stood at 651 ft (198.5 m), but a 90 ft (27.5 m) extension was added as part of a 1996 renovation. It has the headquarters of CenterPoint Energy. When Reliant Energy moved out of the building and moved into the new Reliant Energy Plaza in 2003, the company left over 400,000 square feet (37,000 m) of space vacant.
