The Nordic Regional Coordination Centre (RCC) is owned by the electricity Transmission System Operators (TSOs) in the Nordic region. We support the national TSOs in maintaining the operational security of the power systems across Finland, Norway, Sweden and Denmark.An RCC does many of the same advanced calculations that happen in the TSO control rooms like capacity calculation and security analysis but on a regional level. The regional analyses ensure increased coordination and effectiveness.Ongoing analysis of data from the four power systems and close coordination of activities improve the security in the operation of the Nordic power systems. Regional generation adequacy information and coordinated capacity calculation as well as outage planning improve the overall efficiency of the systems and thus further conditions in the Nordic power markets.
