[en] A new Multi-annual Planning of Investments (PPI) for power generation in France has been realized in order to meet the conclusions of the Grenelle Environnement Forum for a better management of energy demand and a large investment program in non carbon energies. Some renewable energy development targets are set for 2020: 25000 MW for wind energy (19000 MW on land and 6000 MW on sea), 5400 MW for solar energy, 2300 MW for biomass energy, 3 TWh.year and a peak capacity of 3000 MW for hydroelectric power. Concerning nuclear energy, power plant operation will be optimized and two EPR-type reactors will be launched; the minimum required of conventional thermal power plants will be modernized in order to reduce its atmospheric emissions. Power systems in two regions (Brittany and PACA) will be reinforced
