The expected transition of the heat wave from the Pyrenees and the Apennines to Southeastern Europe has led to a high demand for electricity in the Balkans, with the open possibility of supply constraints, according to the Montelnews portal, citing sources from electricity traders in continent.
"Right now everyone is buying electricity," an electricity trader told Montel, noting that demand for air conditioners is expected to grow in the Western Balkans.
Electricity prices in Southeast European exchanges, according to Montelnews, ranged between 126 and 171 euros per megawatt hour on Tuesday, with the highest price of 443 euros per megawatt hour in Slovenia.
In Western countries, the same values ??in electricity trading are significantly lower, where in Germany they are 108 euros per megawatt hour.
Taking into account the expected temperature trends in the Balkans, Montelnews, among other things, draws attention to the statements of the National Meteorological Service of Serbia that this week's hot period in the entire region may bring temperatures above 40 degrees.
"Grid operators and energy traders in Eastern Europe are preparing for possible supply constraints and increased demand caused by temperatures that could rise by up to 12 degrees Celsius compared to previous weeks," commented Andrea Tura, an expert meteorological at the Italian Meteo forecast service.
In support of the claim that the heat wave causes major price disturbances in the electricity market, the portal cites data from Spain.
"The heat wave is expected to further increase electricity prices in the regional markets of Southeast Europe until the end of this week," a source from the European electricity market told Montelnews, pointing to the potential impact of the fires in Greece on the prices.
The forest fires, added Styliani Sarri, an engineer at the Greek electricity grid operator DSO Hedno, in a statement to the aforementioned portal, worsened the impact of the heat wave in Greece.
"This is the week with one of the highest system loads in Greece, due to the peak tourist season. Because of this, prices may increase and the possible drop in photovoltaic production due to forest fires may worsen the situation," Sarri told Montelnea.
The severe nexus of electricity supply in South-Eastern Europe was demonstrated by the collapse of the power systems of Montenegro and Albania and parts of Bosnia-Herzegovina, Greece and Croatia on June 21 this year in circumstances that are still being investigated.
The investigation is led by the European energy grid operator Entso-E, which in mid-July gave a preliminary report on the causes of the mentioned "blackout".
The preliminary report of the European operator starts from the information that the epicenter of the regional interruption of the electricity supply was in Montenegro, warning the findings of the investigation that on the eve of the "blackout" about 2000 megawatts of electricity were distributed to the Montenegrin network with a submarine cable from Italy, while exports of 417 megawatts were sent in the opposite direction to Italy.
