New Substation to Increase Grid Reliability in the City of Athens

ABB has won an order worth $20 million from Public Power Corporation (PPC), Greece’s national power utility, to build a 150/20-kV substation in Athens.

The Ampelokipi indoor gas insulated switchgear (GIS) substation will be located in the city’s metropolitan area. It will increase the capacity of the urban power distribution network and facilitate reliable power supply to household consumers as well as hospitals, government and commercial buildings.

ABB has turnkey responsibility for the design, engineering, supply, and installation of the substation. Key equipment to be supplied includes eight 150-kV GIS bays, three 150/20 -kV 100-MVA power transformers as well as 150 arc-proof type switchgear panels. The substation will also be equipped with an IEC 61850 substation automation system to facilitate open communication between the numerous control and protection devices within the substation and beyond.

”The compact design and footprint of the substation makes it ideal for densely populated urban areas where space is limited. The new substation will also enhance the reliability of high-quality power supply,” said Oleg Aleinikov, head of ABB's substations business, a part of the company’s Power Systems division. ”ABB has previously supplied similar GIS installations for the Athens 2004 Olympic Games and we are pleased to support the further development of the city’s power infrastructure.”

This type of environmentally friendly electrical installation minimizes space requirement and visual impact on the surroundings. It also eliminates the need for overhead transmission lines, as it is connected to the grid via underground cables. ABB is the world’s leading supplier of GIS switchgear and substations covering a range of voltage levels up to 1,100 kV.
