District cooling

Indy has the 2nd largest district steam system. Sorry no boiler pictures, couldn't get in. But did get a tour of the main chilled water plant, one of 6 on the system. If you arrow through the pictures, there's some text for each one.

For you steam buffs, there's the 100+ year old steam plant across the street from Lucas Oil Stadium. It was just converted to gas. 60% of the steam comes from this plant, 40% comes from burning garbage on the SW side of town. The district system is the smallest of 3 customers of the garbage plant. When a new city hospital was built, Citizens Thermal built a chiller/boiler plant next to it as backup. On a very hot day, the chilled water system is maxed out. They didn't say how the steam holds up in bitter weather.
