Our DC sites is located near some of the strongest grid points i Norway.
Nordkraft’s approach of finding suitable DC sites focused on finding sites close to strong transformer stations with available capacity. This means that all of our sites are located close to strong transformer stations that has redundant grid connections and which is situated near the north/south main grid highway (420 kV) in Northern Norway.
Norway offers you some of the strongest grid systems in the world. This is highlighted by the Energy Architecture Performance Index in 2017, where Norway was ranked 2nd due to vast available of renewable power, our grid security and well-developed interconnections.
Statnett, Norway’s TSO, had a reliability of ~99.9999% in 2018 and 99,9991 in 2019. It was commented in Statnett’s 2017 annual reports that “Reliability of supply in the power system has improved in recent years, measured by a reduced amount of nondelivered energy and a reduced number of operational disturbances”.
Norway has a decentralized production system, with over 1,500 hydropower plants and tens of wind parks situated all over Norway. Such decentralized production system improves the reliability of supply compared to having a few large-scale power plants.
High security of supply is also achieved by cooperation with power intensive industry companies, where companies can through different structures offer flexibility by reducing production levels in times with low grid capacity and/or generating capacity.
The map shows the normal flow of power in Northern Norway. Due to an oversupply of power, the power is sent southwards through Norway, Sweden and Finland.
