Data released by grid operator Redes Energéticas Nacionais (REN) shows solar accounted for 19% of total consumption, surpassing wind, which contributed 13%.
In total, renewable sources covered 53% of Portugal's electricity demand last month.
The shift underscores the accelerating penetration of intermittent renewables in the national mix.
