The three scenarios are: The full storage (Fig. 4a), partial storage with load levelling (Fig. 4 b) and partial storage with load limiting (Fig. 4 c). In the full storage scenario, the storage can cover the entire refrigeration load during peak hours, while a high capacity refrigeration system is required to fully charge the CTES during off-peak hours.
