A fresh fish has a short limited fresh time without treatment. To maintain quality and prevent spoilage, several treatments are carried out especially using a cooling method. In the fish storage industry, most energy consumed by cooling equipment. With the rising of energy prices, the frozen fish industries are looking for possibilities to reduce production costs by saving energy. Energy-saving assessment can be seen from the specific energy consumption (SFC) which is a comparison of the amount energy needed to produce a product (kWh/ton of product). This article will be discussed about data collection and analysis to get the value of SFC for process and storage in the fish freezing and storage services industry. The measurement result shows that the value of SFC for cold storage are 4.2 kWh/ton. The SFC used by the air blast freezer (ABF) with 5 tons capacity are 91 Wh/kg. The consumption of electrical energy in ABF is strongly influenced by matched between the capacity specifications of ABF and the number of fish to be cooled. If the 5 tons ABF is only filled less than 2 tons of fish, the SFC will increase more than 50% up to 145 Wh/kg.
