Cold Thermal Energy Storages (CTES) can shift the energy consumption in time and thus help to avoid inefficient part load operation of the refrigeration system. This can potentially lead to a higher overall efficiency of the system. Being able to shift the energy consumption to periods of lower electricity prices can further reduce energy costs.
