Recommended in the long term, before investment needs in Asker

Planning work not commenced Possible location slightly west of Gulskogen/Drammen Requires AT system Oslo-Drammen

Indication: New static converter station Power requirement 60 MVA

Turnkey contract: 2032-2035

• Asker can be closed when Drammen and Hønefoss converters are operational

13 Plans in the Oslo area

• New converter station at

Necessary increase in performance on Dovre Line south Linked to new double track plots south of Hamar (Kleverud – Sørli/Åkersvika)

Concept design work completed. Location is determined

The project is in the detailed planning phase …… (more info in next entry)

• Closure of Tangen converter station (losing track access) • Closure and relocation of mobile converter station at Rudshøgda (Used elsewhere, e.g. on the )

14 Plans for the Sørlandet Line

• Refurbishment/upgrading of Kjelland converter station

Necessary increase in performance on Sørlandet Line

Concept design work has commenced

Provisional plan: New static converters Power requirement 30 MVA

Turnkey contract: 2019-2021

15 Plans for the Sørlandet Line

• Refurbishment/upgrading of Nelaug converter station The concept design work will commence in 2018 Concept development for modernisation of station in or outside existing rock caverns

Implementation: 2020-2022

• Increased performance in Leivoll converter station Planning work to commence in 2024 Preparations at the station and replacement of rotary converters

Implementation: 2026-2027

• Closure of Sira and Krossen converter stations Can be implemented when the two previous measures have been implemented

16 Plans for the Dovre Line

• Upgrading of Dombås converter station Necessary increase in performance south of Dovre Replacement of rotary converters to 2x10 MVA

Implementation: 2023-2025

• Possible provisionally increased performance at converter station Poss. replacement of rotary converters

17 Plans for the Dovre Line

• New converter station at Berkåk

Necessary increase in performance at Dovre Line north / electrification of Røros Line Planning work not commenced. Possible reuse of rotary converters (typically 2x10 MVA) Requires at least a new building and switchgear installation.

Implementation: 2026-2029 or later:

• Closure of Oppdal/Lundamo/Stavne converter station To be assessed when Berkåk is operational Also to be viewed in conjunction with the establishment of Hell converter station (ETM project)

18 Plans for the Dovre Line

• New converter station at Fåvang

Refurbishments and rationalisation on the Dovre Line Planning work not commenced, but requires at least a new building and coupling installation. Possible reuse of rotary converters (typically 2x10 MVA)

Implementation: 2030-2033 or later:

• Closure of Fåberg converter station Can be implemented when Fåvang is operational • Closure of Fron converter station Can be implemented when Fåvang is operational
