Every developer sitting on a Romanian solar or wind pipeline right now is holding an asset whose value depends on a single variable: when it gets a grid connection. Not the permit. Not the PPA. The connection date. And for the first time in years, three separate processes, the EU Grids Package in Brussels, Romania’s own connection queue overhaul, and Transelectrica’s interconnection build out, are moving on the same timeline, all pointing toward 2027.
That convergence is why this matters now, not as background policy noise, but as the single biggest input into how you underwrite, sequence and price a Romanian renewables pipeline over the next 18 months.
What’s Actually in the EU Grids Package
The European Commission presented the European Grids Package on 10 December 2025, built around two legal instruments: a revision of the TEN-E (Trans-European Networks for Energy) regulation and a new permitting directive. On 26 June 2026, the Council reached its general approach, and the file now moves into trilogue negotiations with the European Parliament, with a final agreement targeted for late 2026 or early 2027.
The substance is significant for anyone with capital tied up in a connection queue:
Coordinated planning. A new “central scenario” methodology, built jointly by the Commission and member states, will identify cross-border and national grid bottlenecks across electricity, hydrogen and gas networks, replacing today’s patchwork of national plans that rarely talk to each other.
Congestion income redirected to grids. Member states agreed to reinvest a rising share of unspent congestion income into cross-border projects: 10% starting 1 January 2028, climbing to 25% by 2031. It’s a smaller commitment than the Commission originally proposed (the Council stripped out a plan to centralise these funds under Brussels), but it still puts real money behind interconnector build out.
Faster permitting. Digital one-stop-shop portals, “overriding public interest” status for grid and renewable projects, and tacit approval clauses if authorities miss statutory deadlines.
Emergency repair funding. A new category specifically for rapid replacement of critical interconnector components, a direct response to recent sabotage and cyber incidents affecting subsea and cross-border links.
The scale of the underlying investment gap is what makes the politics so charged. The Commission’s original 2023 estimate put grid investment needs at roughly €584 billion by 2030. The European Investment Bank notes that annual EU grid spending has already roughly doubled over the past decade to around €70 billion in 2025, while EIB grid financing itself nearly tripled between 2023 and 2025, to €11 billion. Industry bodies like Eurelectric are now calling for investment to double again on top of that. Whichever multiple ends up in the final headlines, the direction is unambiguous: Brussels is trying to unlock a step change in grid capital, not an incremental increase.
Why 2027 Is the Year That Decides It
Two numbers explain the urgency. Across 16 European countries, roughly 1,700 GW of renewable capacity is currently stuck in connection queues, about six times Germany’s entire installed capacity. And on current trends, 80% of the EU power system is expected to miss the bloc’s 2030 interconnection target of 15% of installed capacity.
That is the backdrop against which the Grids Package trilogue will conclude, most likely in late 2026 or early 2027, right as Romania’s own reforms hit their first real test. It is also why “the EU Grids Package” and “grid connection queue Romania” are no longer separate stories for pipeline holders. The EU-level rules on permitting speed and congestion-income reinvestment will directly shape how fast Transelectrica can execute the interconnection projects that ultimately determine when a given ATR (grid connection approval) turns into an energised project.
Romania Is Rewriting Its Own Connection Queue
Romania has been running its own parallel reform, and it is arguably further along than the EU-level process.
For years, ANRE operated a first come, first served system that let developers reserve capacity with minimal financial commitment. The result: according to Romania’s transmission operator, only about 12% of projects that received guaranteed connection offers ever went on to sign a connection agreement. The rest sat in the queue, blocking capacity that serious developers couldn’t access.
That is now changing. ANRE Order 53/2024 and subsequent amendments, effective from 1 January 2026, require generation projects over 1 MW to post a grid bond (initially 5% of connection tariff costs, later guidance points to deposits around EUR 20 to 30 per kW), enforce chronological, fully-documented queueing of solution studies, and impose binding deadlines: 12 months to secure authorisations after contract signing, 18 months from initial permit, with automatic loss of connection rights and forfeiture of guarantees for missed deadlines.
The centrepiece is a shift from first come, first served to competitive capacity auctions, Romania’s first auction is currently planned for October 2026, having already slipped once from an initial January 2026 target. Around 70 ATRs issued after August 2024 are under active monitoring for non-compliance; regulators estimate their cancellation could release roughly 3.5 GW of capacity back into the market.
For pipeline holders, the practical read is this: Romania is actively cleaning speculative capacity out of its queue and replacing it with a system that rewards developers who can actually finance, permit and build. That is disruptive in the short term for anyone relying on legacy reservations, but it materially improves the odds that a real, well-capitalised project gets a genuine connection date rather than sitting behind speculative filings indefinitely.
Transelectrica’s Interconnection Build Out
The queue reform only matters if the physical grid can absorb the capacity, and Transelectrica’s investment plan is scaling to match. The transmission operator’s ten-year development plan through 2029 carries a price tag of roughly EUR 1.16 billion, including around EUR 300 million in EU grant support. Its 2026 investment budget alone rose to 914 million lei, over 30% higher than 2025, funded in part through the EU’s Modernisation Fund and Romania’s National Recovery and Resilience Plan.
Concrete projects underway include upgrading the Reșița, Timișoara, Săcălaz, Arad corridor from 220 kV to 400 kV, a new Oradea to Józsa 400 kV line into Hungary, a new interconnector strengthening the Romania-Serbia link, and continued integration of renewable-rich Dobrogea and Moldova regions with the national backbone. Transelectrica’s stated ambition is to roughly double bilateral cross-border transmission capacity to around 5 GW. On the connection side, the operator has already signed contracts for 3 GW of wind capacity through 2026, with a further 3 GW holding technical approvals in the same window.
The Case for Romania
Put the three threads together and a fairly objective pattern emerges, not a promotional one. The EU Grids Package is set to accelerate permitting and channel more congestion-income funding into cross-border links right as Romania’s national reforms are forcing genuine capital discipline into its own connection queue, right as Transelectrica is executing a funded, multi-year interconnector programme rather than a paper plan.
None of this is risk-free. Romania’s auction has already slipped once, trilogue negotiations in Brussels could still change the final shape of the Grids Package, and tighter guarantee requirements raise the entry cost for smaller developers. But relative to markets where queues remain congested with no reform in sight and no funded build out to relieve them, Romania is one of the few places in the EU where policy, regulation and physical infrastructure investment are currently moving in the same direction at the same time. For pipeline holders whose returns depend on connection timing, that alignment, not the headline megawatts in the queue, is the number worth watching into 2027.
Momentum Energy’s View
We build and manage solar projects in Romania every day, which means we live inside this connection queue rather than watching it from a distance. What we’re seeing on the ground matches the policy signal: ANRE’s tighter documentation and guarantee requirements are already separating serious, fundable projects from speculative filings, and Transelectrica’s investment pace has visibly picked up over the past 18 months, not just on paper but in the substations and lines we work around daily.
Our read for pipeline holders is straightforward. The next 12 to 18 months, through Romania’s first capacity auction and the final shape of the EU Grids Package, will determine which projects convert into energised assets and which stay stuck. Sequencing, documentation quality and grid-readiness now matter as much as siting and permitting once did. We work with developers and investors to stress test pipelines against exactly this kind of regulatory shift, and we’d rather have that conversation early, while there’s still time to adjust, than after an auction result locks in the outcome.
If you’re holding Romanian pipeline and want a clear-eyed view of how these reforms affect your specific projects, we’re happy to talk.
