Multi-Criteria Method for Sustainable Design of Energy Conversion Systems

International audienceEnergy production systems for isolated communities lacking national energy grids are, in many countries, associated with first energy access of rural or developing regions. Those communities require innovative design methods to select relevant solutions for sustainable developments in a context of continuously strengthening climate change conditions. The design of an innovative solution goes through multiple stages. After identifying opportunities, analyzing a context and identifying a problem, we are interested here in the process of imagining solutions and guiding reflections so that the resulting solutions are sustainable. Sustainability is analyzed from technical, economic, environmental and social angles. The two main visions for imagining solutions, the value proposition and the technical solution, are discussed. We are then developing a multi-criteria method of sustainable design to imagine the technical solution of an electricity production system in a context of first access to energy for isolated communities. This method serves as decision and discussion support between all stakeholders (community, decision makers, project managers) so that they collectively build a sustainable solution. As the exchanges progress, criteria from different fields meet and complement each other to allow the development of the specifications for the energy production solution which will be ultimately developed
