Secondary reserves of EDF SA production plants

#### Summary: Secondary reserves of EDF SA’s nuclear and thermal flame-fired power plants. #### Detailed explanation of the secondary reserve mechanism: At all times, production must be equal to consumption. RTE ensures this balance in real time and takes into account consumption or production hazards (weather, availability of production stock, etc.). To maintain the balance between supply and demand, RTE must have an adjustable reserve of power at every moment, up and down. There are three types of reservations that can be requested successively: * Automatically activated reserves: frequency system services, which are broken down into the primary reserve and the secondary reserve * Manually activated reserves: the adjustment mechanism that constitutes the tertiary reserve To build up these reserves, an integrated EU-wide balancing market has been created. Its main areas are defined in the European Electricity Balancing Regulation, which describes the technical, operational and commercial rules on the acquisition of balancing capacity, the activation of balancing energy and their financial regulation.
