It considers capacity expansion, decommission and unit commitment in the sectors of power generation, heating, industry, and transport. In this particular case, transport sector module is expanded to provide realistic modelling of different naval fleets’ energy consumption, on the example of fishery fleet. This is performed through the inclusion of learning curves of different technologies that are expected in the naval transport, to replace the old internal combustion engine power drives and the demand curves that characterize the fishery fleet. Results include the changes in the variable renewable energy integration in the sectors of energy demand, general and bottom-up assessments of economic benefits and emissions reduction. Results demonstrate that the presented approach can offer better insights into the changes that are needed in an energy system based on renewable energy sources, in case of detailed modelling of the energy needs emphasized by a fishery fleet and different dynamics of its decarbonization.
