This paper focuses on the electricity sector and on problems of exibility and reliability in power systems in order to improve results provided by long-term planning exercises: exibility needs are integrated as an additional criterion for new investment decisions and, reliability requirements are assessed through the level of electrical losses they induced and a related cost. These approaches are implemented in a long-term planning model and demonstrated through a study of the Reunion Island
