The first large capacity steam-turbine generator was placed in commercial service by the Commonwealth Edison Company in Chicago, Ill. The turbine required one-tenth the space of the reciprocating engine it replaced, weighed one-eighth as much, and cost only one-third as much. It was driven by steam at 175 pounds per square inch at 375 degrees Fahrenheit and developed 6,700 h.p.
