The continuous operation of the energy “bridge” between Crete and Attica is ongoing, ensuring the island’s energy sufficiency and preparing for its definitive independence from polluting power units. This follows the successful completion of system acceptance tests (SAT) by the Contractor, in collaboration with Ariadne Interconnection and ADMIE.
Crete-Attica electrical interconnection: The largest energy transfer project enters final phase
The interconnection is set for continuous operation over the next two months, after which the largest and most complex electrical energy transmission project ever built in the country will enter commercial operation.
During the last quarter, successful electrical energy load transfers to and from Crete were completed under various operational scenarios. Tests of maximum transmission capacity for each pole were also conducted, confirming the electrical interconnection’s capability for bidirectional energy flow under real operating conditions.
The electrical interconnection between Crete and Attica was implemented with co-financing from the Environment and Climate Change Operational Program (NSRF 2014-2020) and the “Environment and Climate Change” program of NSRF 2021-2027, totaling 535.5 million euros. This electrical energy transmission project ensures complete energy sufficiency for Crete’s four regional units while gradually phasing out the island’s polluting power generation units.
The island’s electrical parameters will be fully integrated into the electricity market model used for the mainland system, achieving secure power supply for Crete’s consumers without requiring local power plant operations. Correspondingly, this will end the hybrid model temporarily implemented for Crete from 2021 until its double interconnection through Attica and the Peloponnese.
