Abstract [sv]

Telekombranschen har de senaste decennierna upplevt en stark tillväxt, framförallt i urbana områden och västvärlden. Nu när denna tillväxt även sker i utvecklingsländer och dess landsbygd, söks det efter nya sätt att försörja basstationer som ej är kopplade till elnätet med energi. Syftet med detta examensarbete är att studera och analysera framtida hållbara energilösningar för basstationer inom telekombranschen.

Detta görs genom att kartlägga alternativ, analysera vilka hinder och möjligheter som finns samt undersöka vilka kompetenser som krävs för en vidare utveckling. Arbetet har framförallt baserats på intervjuer av aktörer i telekombranschen samt litteraturstudier.

Studien visar att de tekniker som i framtiden har störst potential att ersätta dieselgeneratorerna idag är solceller samt småskalig vindkraft. För att denna utveckling skall ske krävs det innovationer och nya sätt att implementera energisystem med basstationer. I framtiden kommer det även finnas ett stort behov av projektering och modeller för att dimensionera samt optimera basstationers energisystem.

Abstract [en]

In recent decades, the telecom industry has experienced a rapid growth in urban areas and the western world. This growth is now spreading towards developing countries and their rural areas, where proper energy grids may be lacking. In order to cope with insufficient energy infrastructure and improve their services in rural areas, the telecom industry is now looking to develop better off-grid telecom base stations. The purpose of this thesis is to study and analyse future sustainable energy solutions for off grid base stations in the telecom industry.

This is purpose will be met by mapping possible alternatives and analysing what advantages and disadvantages these alternatives have, as well as investigating what competencies the industry needs. The work is foremost based on literature studies and interviews of stakeholders in the telecom industry.

The study concludes that photovoltaic solar cells and small scale wind power are the two energy generating technologies that has the greatest potential of replacing the diesel generators that are now commonly used on off grid base stations. In order for this to happen, two important areas that the industry needs to focus on is innovation and new ways of implementing the energy systems with base stations. The demand of planning, dimensioning and designing the energy systems will increase in the near future as the renewable energies increases their market share.
