Feasibility of implementing energy management system in ports

As a key element of the maritime industry that consumes considerable amounts of energy, ports have the potential to tap on higher energy efficiency and renewable energy production to reduce their environmental impact. Ports can also achieve financial benefits when they have better energy management. This study investigates the feasibility of implementing an energy management system (EnMS) in terms of cost and benefit for a port. Results from a discrete event simulation done on Singapore's container terminal show that the implementation of EnMS is financially beneficial for terminal operators. There is also lower greenhouse gas emission.
