The Ministry of Environment and Energy convened an emergency briefing Monday night following a major blackout across Spain and Portugal. Energy Minister Stavros Papastavrou led the meeting, which included electricity market officials, to assess the situation.
Sources said the disruption did not affect the broader European market. Quick isolation maneuvers by Spain’s and Portugal’s system operators contained the problem, helped by the limited grid connections between Spain and France.
Officials stressed that the Iberian blackout was unrelated to current electricity management issues in Greece. Greece’s challenge stems from excess renewable energy production and lower seasonal demand – conditions already known and managed through renewable energy production cuts.
Meanwhile, Greek electricity prices continue to fall. The average market price for Tuesday dropped to €58.73 per megawatt-hour, with nearly seven hours of almost zero pricing. Renewables are expected to supply 74% of the national load, supported by favorable weather and the upcoming May Day holiday.
