In the French overseas territories, PV production is no longer marginal and does play an important role in the balance of the system : in case of intermittency, the risk of blackout is a real issue as the insular electric systems are small and could not rely on interconnections. To prevent such a failure, the operator is allowed to disconnect part of the intermittent renewable production when the percentage of this production is reaching 30% of the total production. A monitoring system has been installed to control this limit. By 2020, renewable energies should provide 50% of the electrical insular needs. In addition to the development of non intermittent renewable energy sources (biomass, geothermal, hydro.. .), solutions should be found to integrate a higher percentage of intermittent energy sources: several innovative projects have been launched like Pegase and Millener projects. The purpose of this last pilot project is to contribute to:the improvement of the integration of private household renewable energy sources within the system ; the enhancement of the stability of power grids by real-time electricity supply and demand balancing; the development of enduring economic mechanisms to achieve endogenous development and energy selfsufficiency whished locally. All these projects are aiming to transform the PV production (including the small one) into a real contributor to insular grid operation in a mid to long term perspective.
