According to provisions for system responsibility in the power system (FoS), Statnett shall define Elspot/Elbas areas as part of managing:
- Major and long-term operational congestions occurring in the regional and central grid system,
- Foreseen energy deficit situations in defined geographical areas (§5).
About the adjustment
On Monday 2 December 2013, a change in the Norwegian Elspot/Elbas area definitions will take place, in advance of the new 420 kV line between Sima and Samnanger being put into operation. This line will strengthen the current NO5-NO1 corridor. Accordingly NO5 continues as a bidding area, but with the interface between NO5 and NO1 moved southeast to the lines:
420 kV line Dagali-Ringerike
420 kV line Nore1-Sylling
420 kV line Usta-Ådal
300 kV line Nes-Sogn
300 kV line Hemsil 2-Sogn
132 kV line Flå-Sandum
The interface between NO5 and NO2 will be moved south to the line 300 kV Mauranger-Blåfalli.
The Elspot/Elbas area definition from 2 December 2013
The five Norwegian Elspot/Elbas areas are from 2 December 2013 defined by:
A southwestern Norway Elspot/Elbas area (NO2) limited by the
300 kV line Blåfalli-Mauranger
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
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
420 kV line Dagali-Ringerike
420 kV line Nore1-Sylling
420 kV line Usta-Ådal
300 kV line Nes-Sogn
300 kV line Hemsil 2-Sogn
132 kV line Flå-Sandum
300 kV line Vågåmo-Øvre Vinstra
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 Mauranger-Blåfalli
420 kV line Dagali-Ringerike
420 kV line Nore1-Sylling
420 kV line Usta-Ådal
300 kV line Nes-Sogn
300 kV line Hemsil 2-Sogn
132 kV line Flå-Sandum
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.
