Athens, July 3 2023
IPTO and the Operator of the Bulgarian Electricity Transmission System ESO EAD energized the new, international ultra-high voltage 400 kV electrical interconnection between Greece and Bulgaria. Energy transmission through the new Line commenced on Friday, June 30th, after the close cooperation of the competent personnel of the Transmission System Operators of the two countries for the start of the trial operation.
This is the second Transmission Line connecting the two countries, which significantly increases the margin for energy exchanges between the neighboring systems of Greece and Bulgaria, respectively upgrading the possibilities of cross-border trade and energy security in SE Europe and the Balkan Peninsula. In the following period, a permanent working group staffed by all Operators in the region, will determine the new, gradually increasing, available amounts of transmission capacity on the Greece-Bulgaria border and from the end of the summer season the new Line is expected to start contributing to the cross-border trade.
The total length of the international interconnection, which starts from Nea Santa EHVC in Rodopi and ends at Maritsa East Substation in Bulgaria amounts to 151 km, out of which approximately 30 km extend within the Greek Territory.
The second interconnection between Greece and Bulgaria, the domestic part of which cost 11.3 million euros, is a project of pan-European interest that was included since the beginning of its planning in the Ten-Year Development Program (TYNDP) of ENTSO-E as well as in the list of Projects of Common Interest (PCI) of the European Union.
On the occasion of the new international interconnection’s electrification, the Minister of Environment and Energy, Mr. Theodoros Skylakakis, stated:
“The second, international ultra-high voltage electrical interconnection of Greece-Bulgaria, is an important energy project of pan-European interest. The immediate benefits of this cooperation include: enhancing cross-border trade and strengthening energy security in Southeast Europe and the Balkan Peninsula. More international interconnections will follow, which will further upgrade our country on the European energy map“.
The Chairman and CEO of IPTO Mr. Manos Manousakis, stated:
“IPTO in cooperation with the Bulgarian Operator have completed an important energy project that greatly increases the interconnectivity of the two countries and strengthens adequacy on a regional level. The second international interconnection between Greece and Bulgaria will allow us to better utilize the green energy produced in the region and will contribute to the reinforcement of the European electricity market. With a strategic goal to upgrade the country’s position on the European energy map, over the coming years IPTO is launching new international interconnections with all neighboring states while at the same time supports major intercontinental interconnection projects in the Eastern Mediterranean, with Greece being the main hub“.
