Up until about 10 years ago most of downtown from the river to 8th Ave. were serviced by a thermal plant. They finally shut it down. Most buildings put in electric heating units.
There are lots of huge transformers and switches now under the sidewalks. One blew once and killed 2 people.
That’s interesting.
So who owned and operated the steam plant? Was it the city or was there a utility company that billed users for the steam?
