According to provisions for system responsibility in the power system (FoS), Statnett shall define Elspot/Elbas areas (§5).
An adjustment of the interface between Elspot/Elbas areas NO2 and NO5 will take place Monday 05.12.2011 at 00:00, when the distribution area of Hardanger Energi will be relocated from NO5 to NO2.
The five Norwegian Elspot/Elbas areas are from 5 December 2011 defined by:
A southwestern Norway Elspot/Elbas area (NO2) limited by the
300 kV line Mauranger-Samnanger
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
66 kV line Klyve-Sima
66 kV line Bu-Granvin
22/66 kV transformer Granvin station
22/11 kV transformer Hakestad (Ulvik) station
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 Sima-Klyve
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 Samnanger-Mauranger
300 kV line Fardal-Aurland
66 kV line Granvin-Bu
66/22 kV transformer Granvin station
11/22 kV transformer Hakestad (Ulvik) station
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 NO3.
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.
