Due to necessary maintenance works in the Transmission System and specifically in Circuit 400kV HVSS AG. STEFANOS (813,833) - HVSS PALLINIS (913,893), from 07:00 on Wednesday 20/09/2023 to 17:00 on Saturday 07/10/2023 (continuous outage) and in Circuit 400kV HVSS AG. STEFANOS (853) - HVSS PALLINIS (873) daily during 07:00-17:00 from 20/09/2023 to 25/09/2023, constraints may be imposed that could affect the unit production in the area.
Due to the completion of the works in Double Circuit 150kV SS ALOUMINIO - HVSS DISTOMO, the potential constraints that could affect the unit production in the area, are lifted.
Due to necessary maintenance works in the Transmission System and specifically in Circuit 400kV HVSS AG. STEFANOS (853,873) - HVSS PALLINIS (853,873), until Tuesday 24/2/2022, 14:00, constraints may be imposed that could affect the unit production in the area.
The reconstruction of Koumoundourou HVC in Attica is a “turn-key” project, for the replacement and expansion of existing switching devices of 150 kV and 400 kV with cutting-edge GIS equipment, the addition of two autotransformers and five compensation self-inductors.
The new HVC will be supplying 21 Transmission Lines of 150 kV and 4 Transmission Lines of 400 kV, taking over a significant share of the electricity load in Athens basin.
