Nord Pool Spot has received the following message from Statnett:
According to provisions for system responsibility in the power system (FoS), Statnett shall define Elspot/Elbas areas in order to deal with major and long-term congestions in the regional and central grid system, or possible lack of energy in defined geographical areas (§5).
On Monday 15 March 2010, the Elspot/Elbas areas of Norway will be changed according to the following:
Norway will be divided into five Elspot/Elbas areas, where NO5 is a western area consisting of parts of previous NO1 and NO2. The western area (NO5) is established due to the low reservoir content in western Norway and possible lack of energy. In periods the system reliability will be reduced to increase the import to the area.
The five Elspot/Elbas areas are defined by:
A southwestern Norway Elspot/Elbas area (NO2) limited by the
300 kV line Nesflaten-Sauda
300 kV line Hylen-Sauda
420 kV line Rød-Hasle
420 kV line Rjukan-Sylling
300 kV line Vemork-Flesaker
300 kV line Tokke-Flesaker
300 kV line Hof-Flesaker
132 kV line Grønnvollfoss-Skollenborg
132 kV line Hof-Skollenborg
22 kV line Stanavegen-Fresvik
where the first mentioned nodes are located in the southwestern area (NO2).
A southeastern Norway Elspot/Elbas area (NO1) limited by the
420 kV line Rød-Hasle
420 kV line Rjukan-Sylling
300 kV line Vemork-Flesaker
300 kV line Tokke-Flesaker
300 kV line Hof-Flesaker
132 kV line Grønnvollfoss-Skollenborg
132 kV line Hof-Skollenborg
300 kV line Fardal-Aurland
300 kV line Vågåmo-Øvre Vinstra
66 kV line Klyve-Sima
132 kV single busbar at Litjfossen
where the second mentioned nodes are located in the southeastern area (NO1).
A western Norway Elspot/Elbas area (NO5) limited by the
132 kV double busbar at Åskåra, with one busbar in each area (NO5 and NO3)
300 kV line Fardal-Aurland
300 kV line Sauda-Nesflaten
300 kV line Sauda-Hylen
66kV line Klyve-Sima
22kV line Fresvik-Stanavegen
where the first mentioned nodes are located in the western area (NO5)
A middle Norway Elspot/Elbas area (NO3) limited by the
300 kV line Vågåmo-Øvre Vinstra
132 kV single busbar at Litjfossen
132 kV double busbar at Åskåra, with one busbar in each area (NO5 and NO3)
300 kV line Verdal-Tunnsjødal
300 kV line Namsos-Tunnsjødal
where the first mentioned nodes are located in the area in middle Norway (NO3).
A northern Norway Elspot/Elbas area (NO4) north of the area defined above.
Statnett will emphasize that the divisions between the areas are referring to electrical nodes in the transmission system and are not to be understood as a geographical division.
This area definition will remain until further notice.
