Indianapolis, too [0, 1]:

> the second largest district steam system in the United States. The plant provides steam for heat and hot water to more than 200 commercial buildings and industries across downtown. Perry K's steam also helps power chilled water facilities which cool more than 60 large facilities around downtown. [1]

I grew up going to downtown Indianapolis as a kid and was always freaked out by the steam emanating from the manholes and grates on the street. It turned out not to be an unfounded fear--they have occasionally exploded [2].

You can see the steam plant from pike place market and the steam stacks look like there’s some sort of industrial thing going on which now looks very out of place. It was interesting to figure out what the building was for! The biggest customers are the hospitals up on the hill, and the steam is used to sterilize instruments alongside heating.

A LOT of universities have a central heat plant that pumps hot water to all the other buildings. I think steam has been phases out because it is so much more dangerous and electric pumps make it unnecessary.

Yeah, a lot of institutions are removing steam for heating and replacing it with glycol loops.

Must be a lot lower maintenance.

Much lower maintenance, and VFDs have made pumping glycol a lot more energy efficient than an older across-the-line starter.

Montpelier, Vermont as well: https://www.montpelier-vt.org/427/Project-Background

A lot of military bases have steam pipes all over the place. I think they recently demolished the Camp Lejeune steam plant
