Finland Moves to Prioritise Flexibility in Grid Connection Queue
Finland's plan to rank flexible projects ahead of others in its grid queue aligns with Denmark's June reform and reflects Nordic pressure to manage surging renewable connection applications.
Finland will prioritize flexible projects in its electricity grid connection queue, an official told Montel, departing from the first-come, first-served approach that has left transmission operators across Europe processing backlogs of speculative applications. The shift would put Finland alongside Denmark, which formally ended its own first-come, first-served regime on Monday (2026-06-29).5
Denmark moved first, and explicitly. Copenhagen authorized grid operators to select projects in the national interest ahead of others in the queue, citing a surge in connection applications in recent years as the justification for the rule change. Montel reported the decision, which gives Danish operators discretionary powers over which projects advance that they previously lacked.5
The scale of Europe's queue problem makes the logic difficult to dispute. In Germany, 500 gigawatts of battery projects have applied for grid connections, more than twenty times the country's current installed battery capacity, according to the Economist. First-come, first-served generates an obvious perverse incentive: applicants file early to secure their position regardless of whether they intend to build, and grid operators must process each submission.2
Prioritizing flexibility means favoring assets that can respond rapidly to grid conditions, such as storage, dispatchable demand, and fast-ramping generation, over those that simply arrived first. For Finland's transmission system, that distinction is most acute when solar output peaks at midday then drops sharply in the evening, a daily imbalance that flexible assets are designed to manage.5
Finland's energy minister has also taken a public position in the broader Nordic dispute over grid revenue rules. In June (2026-06-08), the minister told Montel that Finland backs Sweden in its row with the European Commission, while stating the Commission "goes too far" in its proposal requiring transmission system operators to earmark 25% of their unused congestion rents for reinvestment.4
Sweden's stance has been blunter. Energy minister Ebba Busch paused all interconnector projects to other EU states during the week of May 11 (2026-05-11), including a 1 gigawatt link, while Stockholm negotiates with Brussels. A source close to the Swedish government told Montel on Tuesday (2026-05-19) that talks covering new capacity and energy storage rules remain unresolved. Finland's queue reform is proceeding while that dispute continues to cloud the wider framework for Nordic grid governance.1
Grid investment across Europe is accelerating regardless. Italy's Terna is spending €18 billion between 2024 and 2028. France's RTE plans €100 billion between 2025 and 2040. TenneT, which operates in the Netherlands and Germany, has committed €200 billion by 2034. ENTSO-E estimates the total required to meet EU electrification targets by 2050 at €800 billion, the Economist reported.2
But capital commitments alone cannot resolve the mismatch between how quickly projects apply for connections and how fast infrastructure can be built. ENTSO-E has warned that European transmission operators may be forced to reduce renewable energy penetration if data-centre load growth is not properly managed, a signal that queue design carries implications for grid stability, not just for administrative order.3
Finland is also developing domestic thermal storage using sand, a technology its advocates say cuts emissions by 70% without rare earth materials, oilprice.com reported on August 1 (2026-08-01). Under a merit-based queue, dispatchable assets of that kind would logically rank ahead of variable generation projects that do not actively support grid balance.6
For power traders, the practical question is how quickly Finland's reform changes which projects reach the grid and when. PV Magazine has warned that European electricity markets could face greater volatility in the third quarter of 2026, citing high solar output and limited flexibility resources as widening the gap between midday generation and evening demand. If Finland's change accelerates the connection of storage and flexible load, that gap narrows, but the specific criteria by which projects will be ranked have not yet been published.6
