Capacity limitations during automation upgrade of Fenno-Skan 1 and 2 HVDC interconnections

Fenno-Skan 1 and 2 HVDC interconnection between Finland and Sweden with total capacity of 1300 megawatts will be taken out of operation simultaneously between 20th August 7:00 to 21st August 17:00 for works and changes in common equipment. During the works the whole 1300 megawatt capacity between Finland and Sweden will be out of the market. ​The outage of 500 megawatt Fenno-Skan 1 interconnection will continue between 21st August 17:00 to 2nd October 01:00 in order to upgrade the automation and protection system. After commissioning both interconnections will have similar up to date automation systems, which makes it possible to regulate and control both interconnections as one entity.
