The highest wind penetration yet recorded for the whole of Spain is 43%, achieved on November 24 when 9.25 GW was helping meet demand of 21.26 GW.
Spanish wind power has hit another all-time production record with as much as 11.2 GW of the country's nearly 17 GW of wind power feeding power to the grid at the same time during the morning of March 5, reports system operator Red Eléctrica de España (REE). At the time, demand was running at 37.9 GW, with wind supplying 29.5% of electricity required. Earlier that day when demand was about 24 GW, wind penetration hovered for several hours at around 40%, peaking at 42% in the early hours of the morning. The Spanish power system's ability to cope with that level of wind power demonstrates that the decision to unplug large volumes of wind power back in November when penetration reached 38% was made in error, says the Spanish wind power association. REE has admitted it was a mistake (story right).
