Evolution of monthly consumption compared to the same month in the previous year for the months of the selected year and of the previous year, and accumulated evolution in each of the two years.
Consumption evolution corrected for temperature and number of working days compared to the same month in the previous year for the months of the selected year and of the previous year and accumulated evolution in each of the two years.
Repartição da produção por fonte primária – carvão, gás natural, água, vento, sol, ondas, biomassa e outros. Representa-se ainda a importação, caso exista.
A linha mais grossa representa o consumo de electricidade e a linha mais fina indica a soma deste com o consumo em bombagem (consumo das centrais hidroeléctricas reversíveis, utilizado para bombear água de um reservatório para outro mais elevado e que será turbinada posteriormente).
Caso a produção seja maior que o consumo, significa que se está a exportar electricidade, sendo a exportação a diferença entre a produção e o consumo.
