AIM OF THE PROJECT: Supply 24hs/day 7 days/week energy to an off-grid village placed at 3700 AMSL in a desert area of Chile, removing the restriction of the village to having access to energy during night time (no supply from 1 to 8 AM) Minimizing the consumption of fuel from existing diesel generator Testing advanced renewable technologies and storage system in a harsh environment, with large temperature range between day and night and extreme solar radiation in rarefied atmosphere, in collaboration with project partners and research centers. Develop technical solutions for fast growing market RESULTS: The aim of project completely reached The installations of the hybrid system drastically changed the habits of the inhabitants, with also promising economical benefits. Meanwhile, the operation of such advanced plant is giving deep inside knowledge about such kind of systems and possible business model in remote area 07/06/2016 Milan 8
