ROI teamed up with a large production engineering house for this project.  A 3,200,000 gallon chilled water based TES system was added to the campus, and the piping connections to 32 buildings were modified to coordinate the operations with the TES system.

There had been several additions of chillers to the chiller plant, and the 24" and 30" piping within the plant spanned approximately 75 yards.  The main 36" feeds left the plant in two locations, so obtaining a common return point proved to be very interesting.  There was quite a “spaghetti-mess” of piping there.

The system reduced operating costs approximately 40% greater than anticipated, and with the recent rate hikes in San Diego, the savings have been even more spectacular.

This is the largest TES system on the SDG&E power Grid.
