The Greek energy regulatory authority RAAEY reported a dramatic rise in renewable energy source (RES) curtailments in 2024, reaching nearly 900 GWh. This marks a 294% increase compared to 2023, when curtailments totaled 228 GWh. These curtailments were mainly implemented to prevent network overloads and outages.
The surge in curtailments is primarily attributed to the significant growth in renewable energy generation last year, paired with relatively stagnant electricity demand. Around 50% of the curtailments were due to market schedule violations. RAAEY data reveals that between January 18 and December 31, 2024, 826 GWh of RES curtailments occurred during the hours of 8 AM to 5 PM.
Notably, 357 GWh of this total bypassed the markets entirely. If green aggregators had followed market schedules, the electricity transmission system operator ADMIE would have only needed to curtail 469 GWh—43% less than the actual reductions that occurred.
