Cretan small-scale grid link tested, launch by year’s end

Power grid operator IPTO has begun electrification procedures at Crete’s small-scale grid interconnection with the mainland, to the Peloponnese – ahead of a bigger link to reach Athens – and is now preparing to conduct trial tests ahead of the project’s official launch by the end of the year.

The small-scale interconnection, covering a total distance of 132 kilometers, from Hania in Crete to Lakonia’s Neapoli area, is an investment worth 356 million euros.

Its development, including subsea cable installations at depths of 1,000 meters, has remained on schedule despite the pandemic’s obstacles.

The project’s imminent launch will enable the transmission of electricity from the mainland to Crete, high-voltage loads of 150kV, for the first time.

Crete’s large-scale grid interconnection with Athens, scheduled for completion in 2023, will secure exclusive supply to the island from the mainland, ensuring quality electricity supply for the island’s residents and visitors, IPTO has noted.

The overall project’s completion is expected to reduce public service compensation (YKO) surcharge costs imposed on electricity bills to fund island-based power-generating facilities by 300 to 400 million euros per year, while CO2 emissions on Crete will be reduced by 60 percent.
