The aim of this project is to economically and energetically compare different power generation systems that use renewable sources as fuel to increase the temperature of a water line. This line is used to cool the LuxTurrim 5G Poles, which will be implanted in the Kera Area and in the Nokia Campus, in order to use the heat acquired by its electronic components, for the Low Temperature District Heating Network of this area. The extra heat provided to the water line after the poles, comes from a heat generation system that uses renewable sources as fuel, therefore, some scenarios are proposed using different renewable sources and technologies to increase the temperature levels of the water line to the levels of the network. Some of the proposed systems are mathematically modelled in Matlab and others taken from other studies, to determine the energy production per year and also, an economic analysis of each system is made to determine the costs of production, maintenance and start-up. Finally, the Levelized Cost of Energy of each system is calculated, in order to compare them both energetically and economically. The objective is to find out which system is the most suitable to implement in combination with the poles and to cover part of the heat demand of the district heating network, studying the energy and cost of production of eight scenarios using different combinations of technologies and fuels. It should be noted that the scope of this project does not cover the modelling of all systems, therefore some data has been taken from previous studies.
