This Dataset represents the total energy produced nationally.
It is composed of the following elements:
- DGM (Market Generation Diagram) referring to the energy production of producers that are on the market - Information provided by REN;
- PRE (Special Regime Production) referring to the energy production of producers under special regime;
- Sum of DGM and PRE production (Total).
The data is obtained through total production on the market and producers under special regime. At the end of each 15-minute period, the meter stores the total amount of energy during that interval.
The update frequency is daily.
Use case: This data allows us to monitor the evolution of energy produced at a national level.
