100% production saw excess exported to Spain
Electricity consumption in Portugal was supplied by renewable sources (mainly wind and water) for more than 24 hours over the weekend due to “favourable wind and rain conditions”, REN – Redes Energéticas Nacionais announced yesterday.
In a statement, REN said that electricity consumption had been supplied by renewable sources since 22:30 on Friday.
From that time until 00:00 on Saturday, 97.6 Gigawatt hours (GWh) of wind energy, 6.6 GWh of solar energy and 68.3 GWh of hydroelectric energy were generated, which “ensured the consumption of 137.1 GWh”.
“Production surpluses have been exported via the interconnector with Spain,” the statement added, suggesting that “if the weather forecasts for (Sunday) are confirmed, everything points to the situation remaining the same and a whole weekend with 100% production from renewable sources”.
The company also stated that, since 09:00 on October 24, electricity consumption in Portugal has been ensured by renewable energies, despite “resorting to importing electricity from Spain at certain times”.
“The transition to full export took place on Friday, October 27 at 5 pm, when Portugal became an exporter of electricity 100% of the time,” said the statement.
According to REN, for reasons of balance between generation and consumption, on the same day, two groups of two natural gas combined cycle thermal power stations went into operation between 16:00 and 22:30, “at the end of which electricity consumption in Portugal was supplied with 100% renewable production, and still with an export balance to Spain”.
