Cool TES is well understood to reduce peak electric demand in DC systems, and thus reduce electric costs. However, by incorporating TES, total installed chiller plant capacity can also be reduced from needing to match the peak day's instantaneous peak system load (without TES), to merely matching that peak day's 24-hr average load (with TES). The capital saving from reducing the installed chiller plant capacity is often more than the installed cost of a large CHW TES installation; thus, large CHW TES often reduces net capital cost. The experiences of the leading GCC DC owner-operator and a US-based consulting engineer provide numerous examples. The prime opportunities include: 1) new DC construction, 2) retrofit DC expansions, and 3) retirement/replacement of older DC capacity.
