In September, the consumption exhibited a variation compared to the same period of the previous year, of 6.7%, or 3.3% when adjusted for temperature effects and number of working days. The accumulated annual evolution stands at 3.3%, or 2.8% with temperature and working days correction.
For the selected year, indication of monthly consumption, its variation compared to the same month in the previous year, its variation compared to the same month in the previous year but corrected for the effects of temperature and number of working days, and also the evolution and evolution corrected for the effects of temperature and number of working days of accumulated consumption since the beginning of the selected year compared to the same period in the previous year, and the same for accumulated periods of 12 months.

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.
