Portugal’s electricity consumption supplied by generation source and net imports; percent, 2023.
Portugal’s electricity consumption is divided by the source that supplied it in 2023. The six categories form a complete 100% balance spanning renewable generation, non-renewable domestic generation and net imports. Wind supplied the largest share at 25%, followed by hydropower at 23%. Renewable sources together supplied 61%, while non-renewable generation and net imports supplied the remaining 39%.
| Rank | Entry | Value | Period |
|---|---|---|---|
| 1 | Wind | 25.0% | 2023 |
| 2 | Hydropower | 23.0% | 2023 |
| 3 | Net imports | 20.0% | 2023 |
| 4 | Non-renewable domestic generation | 19.0% | 2023 |
| 5 | Solar photovoltaic | 7.0% | 2023 |
| 6 | Biomass | 6.0% | 2023 |

Evidence: Supports the 2023 renewable-source, non-renewable-generation and import-balance shares of Portuguese electricity consumption.
This comparison concerns electricity consumption rather than total energy use. Net imports are a balance contribution, not a generation technology.
The annual electricity balance preserves four renewable-source shares, non-renewable domestic generation and net imports. The six mutually exclusive contributions reconcile to 100% of consumption.
All six shares use the same REN electricity balance, consumption denominator and 2023 period.
