Highest and longest
The highest power consumption in Norway was measured at daytime on February 5, 2001. During the tenth hour, between 09.00 AM and 10.00 AM, Statnett recorded an all time high of 23.054 MW (23,05 million kilowatts). This is 1.3 million kilowatts more than the old record, which was set on the previous Friday, on January 2. The earlier record was from January, 1996.
Longest fiord stretch
Sognefjorden, West in Norway, is the longest fiord stretch in the country: 4.597 meters. Only one stretch in the world is longer: The Ameralik stretch on Greenland (5.376 meters). This was built by people from Stantett, employing Statnetts equipment.
Heaviest ice load
305 kilos of ice in one meter is the heaviest ice load measured on a power line. This was recorded in April, 1962 on a 20 kV line from Voss to a TV transmitter (Lønahorgi).
In general, 2-3 kilos of ice is considered a heavy load. Power lines are normally created for 0,5-1,5 kilos of ice per meter.
In the Norwegian main grid, most lines are dimensioned for a minimum of 4 kilos of ice per meter. In addition, we have several long stretches that can handle up to 20-30 kilos per meter. The highest capacity is an ice load of 120 kilos per line meter. This is found on a 132 kV-line crossing over Ospefonna between Brandhol and Grytten.
The three tallest power line masts in Norway are placed by Karmsundet. Their height is 143,5 meter.
Longest subsea cable
The world’s longest subsea cable, NorNed, was put into operation in the spring of 2008. The cable is 580 km long and links Feda in Kvinesdal in Norway to Eemshaven in The Netherlands. NorNed is a co-project between Statnett and Tennet.
The cable has a capacity of 700 MW and can supply half the population of Oslo or Amsterdam with energy for one year.
