Power grid operator IPTO has announced a tender for the reconstruction and modernization of the 400-kV Koumoundourou substation serving the wider Athens area, a project budgeted at 46 million euros (57 million euros including VAT).

This facility was constructed in the 1970s, along with four other units, to transmit electricity to the wider Athens area.

The Koumoundourou substation upgrade, one of the projects included in the so-called Eastern Corridor, is expected to be completed in 2024. This corridor also includes the Megalopoli and Corinthos substations, both undergoing upgrades at present.

Interested parties face an August 10 deadline to submit their offers to IPTO, expecting turn-key, ready-to-use delivery.
