RUE Index as a Tool to Improve the Energy Intensity of Container Terminals—Case Study at Port of Valencia

Abstract

A container terminal is a high energy demanding organization. Giving priority to the investments that have a better impact on the minimization of energy consumption is a prime concern of the management board of the Port Authority and container terminals. This study presents a tool for the classification of the processes that take place in the port. The Relevant Use of Energy (RUE) index is described and applied to a case study, the Port Authority of Valencia, which is the main port of the Mediterranean in container traffic. Three different functional units have been discussed for the assessment: Twenty-foot Equivalent Units (TEU), cargo handled, and several container ships that operate in the port. The implementation of specific projects following the recommendation of the RUE Index validated the tool and allowed a reduction of the energy intensity of 29.5%, and a 40% reduction of the cost of energy per TEU between 2008 and 2016. However, there is still room for improvement, and project lines are proposed for this matter. A partnership between the RUE Index and an energy management system ISO 50001 certified and ensures quality data giving confidence to the decision-making process of the management board.
