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)
