Alstom has won a deal worth around €35m ($45m) by the Greek Transmission Utility Independent Power Transmission Operator (IPTO) for the turnkey supply of four gas-insulated substations (GIS) in Greece.

The project will connect three Cycladic islands – Mykonos, Paros and Syros – directly to mainland Lavrion, located in the southeastern coast of Attica, Greece.

IPTO intends the substations to sustainably meet energy demand on the Cycladic islands throughout high-demand summer seasons; phase out dedicated fuel-powered generation plants on the islands in line with EU directives; and lower the cost of energy in the islands.

Alstom will supply three GIS substations (170 kV) to replace small existing power plants on each of the islands. These substations will be connected to a fourth substation, also to be supplied by Alstom, in Lavrion.

The equipment will be manufactured from Alstom units in Switzerland, France, Finland and Turkey.
