Summary / Abstract: France decided to reduce 70% of greenhouse gas emissions from fossil fuel consumption and to reduce the share of nuclear energy in the national power production to 50% by 2035 from the current 75% as part of its energy transition strategy. This leads to strong growth in renewable energies in the future French power system, the massive deployment of electric vehicles and a rapid increase in the self-consumption systems. A large-scale integration of intermittent renewable energies (PV, wind) into the existing energy system will change optimal conditions of yearly full load hours of dispatch-able capacities and power production mix. The challenge is to find a proper balance between renewable production at competitive cost and the remaining system. Different levers are available such as strategic deployment of renewable energy sources, curtailment of renewable production, storage or demand management. In this regards, we conducted a prospective analysis on economic effects led by a large-scale integration of variable renewable power sources in the future power mix. Our analysis considered France’s trajectory of energy transitions towards a low carbon energy system with more variable energy sources. This study aimed to evaluate the average electricity costs of future power mix in France under different scenarios. We have taken different assumptions (costs, electricity outputs, power mix, carbon pricing, etc.) for each case to calculate the average costs of future power systems. In this study, we identified a surplus of power production led by the large-scale renewable integration. We also attempted to define reasonable storage capacities to maintain the security of future system. Our study then concluded with several key messages and policy recommendations to prepare the proper institutional and political strategies.
