In 1989, (a large semi-conductor chip manufacturer) contracted Natgun Corporation to construct a partially buried 2.7 MG, 24,500 ton-hr thermal energy storage (TES) tank for the purpose of saving energy costs by taking advantage of the time-of-use electric rates. The TES system was designed to shift the electric load of the chillers and associated cooling equipment from the on-peak periods (daytime), to the off-peak periods (night time). Then in 1993, (this same large semi-conductor chip manufacturer) contracted Natgun to construct a second TES tank. This second tank was much larger (5.2 MG and rated at 48,730 ton-hrs) and was constructed fully buried beneath a parking lot.

The TES Tanks serving the facilities of this large semi-conductor manufacturer in Dallas, TX area have been in operation for decades providing numerous benefits to the owner including: energy cost savings, plants and reliability in the form of spare cooling capacity for the chilled water system during periods of planned and unplanned downtime of the central plant equipment.
