Provisional plan: Establish new converter station4 static converters Power requirement 60 MVA

Turnkey contract: 2022-2025

• Closure of existing converter station

11

Plans in the Oslo area

• Upgrading of Jessheim converter station

Necessary increase in performance for increasing Intercity traffic

This measure will also facilitate regeneration

New static converter in existing or new building

Turnkey contract: 2027-2030

12

Plans in the Oslo area

• New converter station at Drammen

Recommended in the long term, before investment needs in Asker

Planning work not commencedPossible location slightly west of Gulskogen/DrammenRequires AT system Oslo-Drammen

Indication: New static converter stationPower 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 Hamar

Necessary increase in performance on Dovre Line southLinked 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 Bergen Line)

14

Plans in the Oslo area

• Refurbishment/upgrading of Kjelland converter station

Necessary increase in performance on Sørlandet Line

Concept design work has commenced

Provisional plan: New static convertersPower requirement 30 MVA

Turnkey contract: 2019-2021

15

Plans for the Sørlandet Line

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

Implementation: 2020-2022

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

Implementation: 2026-2027

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

16

Plans for the Sørlandet Line

• Upgrading of Dombås converter stationNecessary increase in performance south of DovreReplacement of rotary converters to 2x10 MVA

Implementation: 2023-2025

• Possible provisionally increased performance at Oppdal converter stationPoss. 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 LinePlanning 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 stationTo be assessed when Berkåk is operationalAlso to be viewed in conjunction with the establishment of Hell converter station (ETM project)
