The Adventures of a Cable and Energy Isolation

The increasing global demand for electricity, driven by the digital revolution, artificial intelligence, and electric mobility, makes energy sufficiency a critical priority for every nation. The European Union is investing heavily in the creation of a pan-European supergrid to strengthen energy security, the green transition, and competition. However, Cyprus remains energy isolated, resulting in consumers being burdened with the highest electricity prices in Europe and facing problems of adequacy and network stability. This isolation limits the integration of Renewable Energy Sources and reduces the contribution of natural gas. The electrical interconnection of Cyprus with Greece and the European network through the Great Sea Interconnector (GSI) is a strategically important solution. The project has been recognized by the EU as a Project of Common Interest and secures political and financial support of €658 million. The project cost is estimated at €2 billion, with Greek consumers covering 37% of the remaining amount after deducting revenues from cable usage. Even in extreme scenarios of zero revenue, the burden on Cypriot consumers will not exceed €850 million, to be paid gradually over 30 years. This interconnection will strengthen Cyprus's energy security and enable the utilization of Renewable Energy Sources.
