NorNed is a high-voltage direct-current (HVDC) subsea interconnector linking Feda in southern Norway and Eemshaven in the Netherlands. The link comprises approximately 580 km of transmission route, mostly subsea, with onshore cable sections and converter stations at each landfall. It was commissioned into commercial operation in 2008. The scheme is...

Project Timeline (17)
Oct 2022Cable Repair
Following the May 2022 cable failure, a repair campaign was carried out on the NorNed subsea HVDC cable, after which the interconnector was able to resume operation in October 2022, albeit with a reduced transmission capacity to limit stress on the cable.
Oct 2022System Restoration
After several months of outage caused by a cable failure, NorNed was brought back into service in October 2022, restoring power flows between Norway and the Netherlands at a derated capacity of 620 MW to reduce mechanical and thermal stress on the repaired cable.
May 2022Major Outage
In May 2022, a cable failure on the NorNed interconnector led to suspension of operations, halting electricity transfer between Norway and the Netherlands while the fault was investigated and repaired.
2014Grid Constraint Event
Due to limitations in Norway’s internal transmission grid, the transfer capacity of the NorNed and Cross-Skagerrak interconnectors is sometimes deliberately curtailed, with Statnett restricting the power that can flow on these links when the domestic network cannot accommodate full exports.
12 Jan 2011Operations Other
On 12 January 2011, the NorNed HVDC submarine interconnector between Norway and the Netherlands was incorporated into European Market Coupling Company (EMCC) operations, integrating the link into coordinated cross-border electricity market coupling and enabling market-based power trading between the Nordic (Nordel) and Continental European systems via the cable.
2011Major Outage
In 2011, the NorNed HVDC interconnector suffered a cable fault that took the link out of operation for approximately seven weeks, interrupting power exchange between Norway and the Netherlands until the issue was resolved.
6 May 2008First Power
The NorNed HVDC interconnector transmitted its first commercial power on 6 May 2008, marking the initial electricity transfer between the Norwegian and Dutch grids following the start of commercial operation of the 580 km, 700 MW ±450 kV subsea cable link.
5 May 2008Commercial Operations Full Power
Commercial operation of the NorNed high‑voltage direct current submarine cable began on 5 May 2008 with a capacity auction, bringing the 580 km, 700 MW ±450 kV interconnector between Feda (Norway) and Eemshaven (Netherlands) into full market-based service.
2008Onss Commissioned
The onshore HVDC converter stations for the NorNed interconnector at Feda in Norway and Eemshaven in the Netherlands were commissioned in 2008, enabling operation of the 580 km, 700 MW ±450 kV subsea link between the two countries’ transmission grids.
2007Cable Installation Complete
Laying of the NorNed HVDC submarine cable was completed by the end of 2007, with the final section of the 580 km interconnector between Norway and the Netherlands installed, enabling subsequent grid connection and commissioning activities.
