The heat wave that has hit Greece is testing not only the resilience of the public, but also the country’s electricity grid, as consumption is expected to hit a ten-year high on Tuesday at 10,700 megawatts.
Tellingly, the operator of the Hellenic Electricity Distribution System (DEDDIE) and the Public Power Corporation (PPC) have revoked employee leave, with some shifts of more than 12 hours in inclement weather conditions in the mines and lignite factories.
Currently on minimum reserves, the system has been in effect since Saturday, when demand started to exceed 9,000 megawatts and gradually increased to 9,600 MW last night.
To meet demand, all gas units are operating at full capacity, as are all available PPC units (Meliti, Megalopolis IV and Agios Dimitrios I-II-III-IV), except unit V in Agios Dimitrios, where the upgrade works are being carried out. The Megalopolis III unit had to reopen after nine months. It had been permanently closed as part of the delignification program.
Megalopolis IV reportedly encountered technical issues on Monday but is expected to come back online on Tuesday.
In response, Prime Minister Kyriakos Mitsotakis called on the public to voluntarily conserve electricity, especially during peak hours.
“We are facing the worst heat wave since 1987… this put a heavy load on the system as demand increased dramatically,” Mitsotakis told reporters during a visit to the headquarters of network operator DEDDIE in Kryoneri, in eastern Attica, Monday.
The prime minister, who also called an extraordinary meeting with the leadership of the Ministry of Energy and Environment, and officials of the power company said authorities had taken all precautionary measures to avoid power cuts.
Mitsotakis said peak hours are 1 p.m. to 3 p.m., but mainly evening hours from 6 p.m. to 7 p.m. until 10 p.m. to 11 p.m.
“If we had to explain it with simple words, these are the times when, unfortunately, because the sun has set, we do not have at our disposal the important energy produced by the photovoltaic that we have installed in the country, ”he noted. .
The call came as temperatures were expected to reach 46 degrees Celsius (115 Fahrenheit) in parts of the country on Monday.
