This paper proposes a support mechanism for energy storage devices for island power systems where intermittent renewable generation is rapidly growing. We base our proposal on the maturity level of storage devices (Chen and al., 2009) and on the linear model for the development of innovations (Foxon et al., 2005). We focus on storage technologies that can be technically developed in island power systems and that achieve the technical needs of these systems. We conclude that the horizon when the power storage shall extend to prevent the development of intermittent renewable generation from being thwarted in these systems, a feed-in tariff with a price varying within the time of day must be put in place.
