RAE, the Regulatory Authority for Energy, appears to have reached a decision requiring distribution network operator DEDDIE/HEDNO to assume management responsibility of Crete’s network when a small-scale grid interconnection linking the island with the Peloponnese is soon launched.

Subsequently, power grid operator IPTO will not need to take on this responsibility until it becomes the owner of the island’s network, RAE appears to have decided.

Just days ago, IPTO made clear it should not assume responsibility for Crete’s electricity network until it acquires this asset from power utility PPC, the current owner. RAE appears to have agreed with this IPTO argument.

The authority held a virtual meeting yesterday with the two operators in search of a solution following the unwillingness, at present, of both to assume management responsibility of the Cretan network.

Normally, when grid interconnection projects for non-interconnected islands are completed, IPTO assumes responsibility of their electricity networks. However, Crete, Greece’s biggest and most populous island, represents a much bigger interconnection project that is being developed over two stages. The project’s second stage, anticipated in 2023, will reach Athens.

It remains unclear how Crete’s electricity system will participate in the target model’s new energy markets once the island’s small-scale interconnection is launched.

The Crete-Peloponnese line will not fully cover Crete’s load, meaning the island may not lose its non-interconnected island status. On the other hand, a considerable 30 percent share of the island’s energy needs will be transmitted through the small-scale interconnection.

An older recommendation by RAE to the energy ministry noted that Crete’s non-interconnected island status should be ended once the small-scale interconnection begins operating for a connection with the mainland grid.
