Abstract

The concept of sustainable energization in rural energy planning, adopting the Advanced Local Energy Planning (ALEP) methodology, is applied within this thesis on a group of facilities located in Bafut, a rural area of Cameroon. The goal of this research is to improve the energy supply and efficiency of the study area through four specific objectives: assess the current energy situation of the study area, assess the energy resources locally available, identify the strategies to improve the energy efficiency and the energy supply and propose a more sustainable energy system for the study area. The total primary energy consumption amounts to 186.2 GJ/month, corresponding to 53.37 toe/year, losses are equal to 70% and final energy of 56.2 GJ/month (16.01 toe/year) is consumed to provide the main services. Three energy drivers are present in the control volume: domestic, public and artisan. The energy sources currently used are firewood, electricity from the national grid, LPG, diesel, and kerosene. The RES locally available are: hydro,wind, solar and biogas. Hydropower annual potential from a nearby river was 140.7 GJ. Wind annual potential was equal to 0.005 GJ/m2 of swept area, while solar potential was 0.02 GJ/m2. The feedstocks assessed for biogas - human, animal, kitchen and agricultural waste - give an expected production equal to 44.85 GJ/month. Energy solution planning was based on matching energy demand with local available RES. Electricity planning was developed by simulating a new supply system with the software HOMER® in Off-grid and Grid-RES options both including hydropower. Grid-RES optimal solution was favorable respect to Off-grid presenting a lower NPC and LCOE. Thermal planning was based on ad-hoc solutions: installation of biogas stoves,ICS and improved bakery oven. In the suggested scenarios TPES was equal to 133.1 GJ/month (38.15 toe/year), losses reduced to 38% and a new service is provided, water heating using biogas boilers and solar thermal collectors, therefore the final consumption increased to 87.2 GJ/month (24.99 toe/year).
