Trajectories of evolution of the electricity mix 2020-2060: Additional analyses, FAQs, Report on data

This report brings some additional elements on three main stakes related to the development of an important share of renewable within the French electric power mix. It first analyses flexibility needs and providing in France in 2020 and in 2050: strong increase of daily and monthly flexibility needs, flexibilities provided by the whole system. Then, it addresses market prices and global costs for the electric power system: gross prices increasing at a more or less high rate according to scenarios with a high variability related to meteorological conditions, analysis of global costs for the French system. It also analyses trajectories from the point of view of electricity export opportunities from France to the neighbouring countries. This study notably revisits some hypotheses and fundamental aspects of the electric power market, and the way they impact published results (notably the demand partial steering and the role of interconnections) within the frame of an economic optimization.
