Portugal’s renewable energy sources generated enough power to exceed total grid demand across the month of March, a new report has found, setting a standard that is expected to become the norm for the European nation.

According to Portuguese grid operator, REN, renewable energy output over the month reached 4,812GWh, surpassing the nation’s total electricity needs for March, which only topped 4,647GWh.

In that time, power generated by Portugal’s hydroelectric dams accounted for 55 per cent of monthly consumption – boosted by drought-breaking rainfall of four times the monthly average – and wind power, 42 per cent.

The achievement comes nearly one year after hydro, wind, and solar power helped push the Iberian country to run on 100 per cent renewable electricity for 107 hours straight. Last March, however, the average renewables supply was 62 per cent.
