CHICAGO (WBBM NEWSRADIO) -- What used to be the Chicago Board of Trade’s largest trading floor will become a ComEd substation.
The 60,000 square foot trading floor opened at 333 North LaSalle Street in 1997. It was large enough to park a 747 airliner.
It was becoming obsolete within a few years-replaced by computers.
Former Board of Trade Chairman Patrick Arbor, who oversaw the project, said it was the last great trading floor and worked well before becoming what he told the Sun Times was a 60,000 square-foot trading flop.”
“It’s all because of one word: technology.”
ComEd bought the five story 300,000 square foot building for about $40 million dollars.
ComEd said the substation will help it meet increasing power demand in downtown. It will power the very technology that put the trading floor out of business.
No changes are expected to be made to the exterior.
