Normally, TNEC offers the District Cooling System (DCS) incorporates Thermal Energy Storage (TES) System technology. TNEC currently operating 5 numbers of DCS Plants using TES technology either ice storage or chilled water storage systems.
TES capitalizes on cheaper off-peak tariff offered by the electric utility company. The system stores cooling energy during off-peak hours and the energy is released via circulating chilled water during peak hours onto the buildings. Only a limited number of chillers need to operate during this period. By adopting this system, the plant consumes less electricity and reduced maximum demand during peak hours.
