Monthly Balance

In April, the consumption totaled 3 981 GWh, with a peak of 7 693 MW on day 3 at 20:15. Renewable generation supplied 89% of the consumption. Hydropower accounted for 44% of the consumption, wind power for 29%, biomass for 6%, and solar for 10%. The balance of exchanges with foreign countries was import equals to 2% of consumption.

Energy Balance

Consumption concerning the power stations’ net generation, on the selected month, on the same month of the previous year, annual cumulative value, corresponding cumulative value from the previous year, and respective variations. Production breakdown according to primary source – coal, natural gas, water, wind, sun, biomass and others – is also shown. In addition to the monthly energy values, the peak value (maximum instantaneous value) observed in the selected month, for each of the primary sources, is also presented.

Production breakdown according to primary source – coal, natural gas, water, wind, sun, biomass and others. These are available individually by selecting “Detailed” or grouped into renewables (water, wind, solar and biomass) and non-renewables (coal, natural gas and others) by selecting “Aggregated”. "Biomass" includes renewable energy cogeneration, forest biomass, biogas and the biodegradable fraction of municipal solid waste. In the "Other Thermal" category are included fuel-oil, the non-biodegradable fraction of municipal solid waste and other waste. If the import balance is positive, its contribution to the consumption of electricity in mainland Portugal is also shown.
The values presented are monthly, for the selected month and for the corresponding month of the previous year.

Transmission Network Balance

Physical balance of the National Electricity Transmission Network. The various parcels that constitute the energy input into the network and the energy output from the network are shown for the selected month. The inputs into the network are divided into Power Plants, Interconnections and RNT Substations, which, in this last case, is energy generated at the Distribution network level and injected in the Transmission Network when generation is greater then local consumption. The outputs from the network are divided into Power Plants and VHV Clients, that are clients connected directly to the Transmission Network, Interconnections, RNT Substations, that are the deliveries to the distribution networks, and Own Consumptions on facilities of the network itself.
The difference between inputs and outputs are the losses in the National Transmission Network.
