Face to the energy transition’s challenge in the Indianocéanie islands, the FESTII project intend to contribute to skills development in the field of electrical energy, integrating Renewable Energies (RE) and Energy Efficiency (EE). In connection with the energy sector professionals, capacity building for teachers in 5 universities (Comoros, Madagascar, Mauritius) is the core of the draft to guarantee the adequacy training-employment.The pragmatic and systematic methodology adopted is inspired from the existing and its aim is to :- have a mapping of the qualifications and jobs needed;- train the trainers on three connected domains: knowledges in RER and EE; pedagogical innovation- particularly in digital resources; the quality approach within the training itself and as a competence to be acquired for students.- enhance existing training models by co-designing with professionals;- ensure student employability;- support entrepreneurship;- carry out a feasibility study of regional joint training in the Indian Ocean region;- establish a regional continuing training catalog;- operationalize an higher education institute’s network for the development of RE and EE in the islands ;- educational equipment’s allowance. At the end of the project:- 30 teachers are trained in RE and EE knowledge and pedagogical innovations;- 10 bearers of entrepreneurial projects;- 9 training programs are revised and adapted view to the context;- a continuing training catalog is be developed;- an HEI’s network is active for the development of RE and EE in the islands.Initiated and supported by the Indian Ocean Commission, an intergovernmental organization including five island states, FESTII aims to contribute to the challenge of the energy transition, by promoting the pooling of regional resources, vector of an impact structuring.
