Electricity consumption in mainland Portugal was fully ensured by renewable sources for almost three consecutive days in a winter period – from 4:00 p.m. on Friday, 9 March, 2018 and 1 p.m. on Monday, March 12, 2018.
According to data from REN (National Energy Networks), the renewable electricity produced in that period was 521 GWh, while national electricity consumption was 408 GWh. The main highlight goes to the national wind farms, which alone supplied 65% of electricity consumption in that winter period.
The record of 107 consecutive hours in mainland Portugal running only with solar, hydro and wind power had already been achieved in a spring period of year 2016, between 6:45 am on May 7, Saturday, and 5:45 p.m. on Wednesday at 11 am.
These numbers reinforce the role of renewable sources in the reliable and safe supply of electricity needs of Portugal.
