Roughly 30 GWh of renewable energy – enough to power four conventional power plants – was discarded in Greece over the Easter holiday weekend as a result of insufficient energy storage capacity. 

With solar production soaring and electricity demand plummeting, grid operators IPTO and HEDNO were forced to cut off green energy from the system to prevent a blackout.

From Good Friday through Easter Monday, operators also limited electricity imports from neighboring countries and ordered unmonitored (“blind”) solar farms to shut down. The most drastic curtailments occurred midday on Easter Sunday and Monday, reaching 2,264 MWh and 2,400 MWh respectively.

Wholesale electricity prices plunged, hitting €66.48/MWh on Easter Sunday, with some midday prices turning zero or even negative.
