Norway is the structural anchor of European energy security. It is the largest producer of both oil and gas on the European continent (excluding Russia), supplies more than half of Nordic oil imports and around half of EU gas imports, and is a structural net exporter of electricity to neighbouring Nordic markets and beyond. The hydropower base is the largest single source of dispatchable flexibility in the Nordic system and functions as a seasonal battery for the wider European grid. This position has expanded over the past two decades through interconnector buildout and rising offshore production, and it makes Norway central to the energy security picture not only of the Nordics but of the EU and the UK.
The flip side is that the same integration that delivers European energy security also transmits European price shocks into Norway. The political tension this generates has become a binding constraint on further interconnector buildout. The current Norwegian government has resisted renewing ageing cables to Denmark; Sweden halted work on the Konti-Skan Connect renewal in May 2026 on similar grounds.
Norway’s institutional position is also the most asymmetric in the region. Norway participates fully in the internal electricity market through the EEA and in ENTSO-E and Nord Pool. Norway is not in the EU and is therefore not bound by the EU Gas Security of Supply Regulation, the EU oil stocks regime, or the EU solidarity mechanism. The 2022 Norway–EU bilateral gas partnership and the 2023 Energy Dialogue provide a forum for supply cooperation but contain no crisis activation procedures. Norway’s own mandatory oil readiness obligation was reduced from 90 to 20 days of consumption in 2007, against IEA recommendation, and has not been revised since.
Key challenges
Single-point exposure of strategic export assets. The Hammerfest LNG plant on Melkøya is the only export route for any Norwegian Barents Sea production. The 21-month outage following the September 2020 fire is the documented precedent. The Mongstad refinery and the major offshore export terminals carry analogous concentration risk, sharpened on the oil side by the closure of the Slagen refinery in 2021.
Oil stockholding that no longer matches the country. The 20-day requirement was set when Norway had two operational refineries and a production base that was assumed to make large domestic reserves unnecessary. Norway remains significantly dependent on imports for diesel and jet fuel, and the obligation has not been revised to reflect either the changed refining footprint or the product-level vulnerabilities exposed by recent global disruptions.
No gas emergency coordination with Nordic neighbours. Norway holds no bilateral gas emergency agreement with any Nordic country. The EU solidarity mechanism does not apply. In a crisis scenario involving disrupted Norwegian output, whether from infrastructure failure, industrial action, or hostile action against offshore assets, no agreed procedure currently governs how Norway communicates with Nordic gas authorities, what information is shared, or on what timeline.
A north-south grid that does not move power as fast as the country produces it. Norway's hydropower base is the largest single source of dispatchable flexibility in the Nordic system, but the transmission infrastructure connecting northern generation to southern demand centres and to the interconnectors that carry power to Denmark, Germany, and Great Britain has not kept pace. The result is persistent congestion on the north-south corridors, large and sustained price differentials between bidding zones, and a situation in which Norwegian generation capacity that is theoretically available to the wider Nordic system cannot always be delivered when it is needed. The political reluctance to expand cross-border interconnection capacity compounds this: the same north-south bottleneck that limits domestic distribution also limits the export capacity that could, in a regional shortage, backstop neighbouring systems.
Recommendations
Recommendation 1. Negotiate bilateral gas emergency agreements with Denmark and with Finland, covering notification thresholds, activation procedures, and emergency volume commitments, complementing rather than substituting for the EU bilateral framework.
Recommendation 2. Adopt explicit security-by-design standards for the offshore production base, with redundant export routing for the Barents Sea basin and pre-agreed repair vessel access arrangements for the gas pipeline network covering both North Sea and Norwegian Sea assets.
Recommendation 3. Develop a Nordic-endorsed investment case for Norwegian north-south transmission expansion. The Norwegian TSO Statnett has long-run grid development plans that identify the required corridors, but the investment has consistently lost out to the political cost of higher prices in producing regions.
