Kapetanovic: “European TSOs close ranks”

06.04.2020

Just like the Coronavirus (though fortunately without negative consequences), electricity flows do not stop at national borders. Cross-border coordination and intensive cooperation between all national transmission system operators (TSOs) are always the prerequisite for EU-wide security of supply, and all the more so in times of crisis with electricity consumption declining across Europe. According to Tahir Kapetanovic, Head of the Control Centre of TSCNET shareholder APG, the Austrian TSO, and also Chairman of the System Operation Committee, the top-level decision board for grid operations at the European Network of Transmission System Operators (ENTSO-E), uniform rules and standards for grid operation are indispensable.

The timely identification of possible threats to the transmission system is also considered to be crucial for the security of electricity supply in Europe. In this context, Mr Kapetanovic directly refers to the field of supporting activities of the European Regional Security Coordinators (RSCs): “The European data exchange is largely automated and runs via state-of-the art IT systems. The evaluated data provide the basis for the planning of electricity transmission. In this way, we can forecast energy flows for the upcoming hours and, if necessary, initiate transnationally coordinated emergency measures in time, such as the starting up of power plants.”

Despite the drastic decline in electricity consumption in Europe due to the restrictions imposed by the Corona crisis, the exchange and trade of electricity across borders is running smoothly. Occasionally, lower power line utilisation offers additional potential for cross-border support. Surplus electricity from western Europe, for example, was redirected via the Austrian grid of APG and via Slovenia to the northeast of Italy. In the face of the pandemic, everyone has closed ranks: In addition to the best possible mutual support, all TSOs have jointly decided that line disconnections for refurbishments and modifications will be temporarily reduced to the absolute minimum. “In doing so, we maximise transport capacity and thus increase the security of electricity supply in Europe”, states Mr Kapetanovic.

The low electricity demand also influences the European generation mix. Renewable energies are still being fully utilised, but thermal power plants, for instance, are being scaled back for cost reasons. This also has an impact on electricity flows in the transmission system. The TSOs therefore continuously forecast electricity flows for the next 24 hours and coordinate possible measures via video conference every evening. To ensure that this is maintained during the crisis, the operational core staff is protected by strict hygiene and organisational precautions, such as team splitting. All TSOs regularly exchange information on their respective measures throughout Europe.
