Power grid operator IPTO’s virtually completed grid infrastructure upgrade in the west of the Peloponnese, a crucial project promising to foster development of regional RES projects and also enable smoother functioning of power utility PPC’s natural gas-fired power station in Megalopoli along with its lignite-fired units, remains on hold, awaiting the energy ministry’s environmental-permit approval of a project deviation forced by monks at a nearby monastery.
The grid project, budgeted at 110 million euros and known as the Western Corridor, runs from Megalopoli to Patras, northwestern Peloponnese. It is planned to link the Megalopoli high-voltage center in the Peloponnese with an existing 400-KV line running across mainland Greece, from Acheloos to Distomo. Just two more pylons, of 400 in total, remain to be installed for its completion.
A court ruling following legal action taken by five monks forced project planners to reposition these two pylons, originally planned for installation approximately 500 meters from the Agion Theodoron monastery in Kalavryta, northern Peloponnese.
The project was initially included in the grid’s plan back in 2006 but its development did not commence until 2018. A related subsea line linking the Peloponnese with the mainland was installed in 2019.
At present, the Peloponnese is mainland Greece’s only area without a high-voltage (400 kV) connection. It is interconnected to the wider Athens area with 150 kV lines, like links used for islands, inhibiting green investments and large infrastructure projects planned for the country.
