IPTO’s Western Corridor power line to be delivered next month

A much-delayed section of a power transmission line project in Greece’s west, dubbed the Western Corridor, for which its developer, IPTO, the power grid operator, was forced to bypass a monastery in the Kalvryta area following objections and legal action taken by its nuns, is expected to be delivered by the end of this month, enabling the wider project’s launch by mid-April, energypress sources have informed.

The new 400-KV double circuit transmission line will enable a high-voltage center in Megalopoli, central Peloponnese, to be connected to 400-KV circuits at Antirio, on the mainland’s southern coast. This will boost the Peloponnese’s existing transmission line connections, currently entirely facilitated by 150-KV transmission lines linked with the wider Athens area and western Greece.

The new Western Corridor transmission line, comprised of aerial, underground and underwater sections, has been 98-percent ready since 2019, the missing link being a section that was originally planned to run by the monastery, at a 500-meter distance. Legal action taken by the Kalavryta-area monastery’s nuns blocked the installation of two pylons, forcing a change of course further away from the monastery.

This section’s development was put on hold for several months as a result of the legal action taken by the monastery.

The project’s launch will not offer additional grid capacity for RES projects. RAE, the Regulatory Authority for Energy, has already factored in the additional increased capacity that would be freed up by the project.

Increased grid capacity will, however, be made available for new RES project additions once the Eastern Corridor, a 400-kV transmission line linking Megalopoli, Corinth and Athens, is completed.
