The Independent Power Transmission Operator (IPTO or Admie) of Greece has announced the suspension of all electricity imports in the hours around noon through May 7.
According to the official announcement of IPTO, the import capacity in interconnections with Italy, Albania, North Macedonia, Bulgaria and Turkey will be zero from 8:00 until 17:00 every day from today through May 7.
The only exception is the direction Bulgaria-Greece, where 100 MW will be allowed for two hours every morning and 250 MW from 16:00 to 17:00.
The reason for the drastic measure is that in recent weekends there have been many consecutive hours of zero and negative prices in the day-ahead market as the production of renewable electricity far exceeds demand in Greece.
It is forcing IPTO, the country’s transmission system operator, to enforce ever higher curtailments, not because of the grid’s inability to handle the extra load, but simply because the power is not needed.
IPTO forecasted that today, on Good Friday, renewables in Greece would peak at almost 7 GW at 13:00, against a system load of just 4.7 GW.
It is notable that on the day-ahead market for today, Good Friday, the price was almost zero for five hours, with renewables at 63% of the production mix. According to IPTO’s projection, renewables will peak at almost 7 GW at 13:00, against a system load of just 4.7 GW.
Traditionally during the Easter weekend, demand falls steeply, meaning that an even greater surplus could occur. IPTO expects the hourly load to fall below 4.5 GW on Saturday and Sunday while the weather will determine the level of solar power production.
When it comes specifically to Bulgaria’s exports to Greece, they tend to increase during the hours around noon. Last Sunday they were near 300 MW in the morning and later they climbed to between 400MW and 500 MW. During these hours, Bulgaria’s wholesale price was slightly lower than Greece’s, meaning there is an incentive for exports.
It is why investors in the Greek renewables market are saying their solar and wind farms are suffering. Low demand creates the problem and imports make it even worse for them.
Undoubtfull proof that no further investments in regenerables is necessary. The star called “Sun” is the source of energy for our planet. Her energy is a supply under million of forms that are not yet understood by humans, even they are acting every second of earth existence…Conclusion: There is a subtle ballance between every life form(including humans) and planet environment. HUMANS SHOULD NOT UNBALANCE IT UNDER SUPERFICIAL KNOWLEDGE AND UNDERSTANDING!🙏🤝
