For more than a decade, securing grid access in Romania looked like queuing at a counter. First come, first served. A €5 guarantee against the connection tariff. An ATR (aviz tehnic de racordare) that, in practice, could sit on the shelf indefinitely.
That counter has now closed.
Effective 1 January 2026, Romania has shifted to an auction-based grid capacity allocation regime, with Transelectrica running the platform and ANRE setting the rules. The first auction window is already on the calendar (30 October 2026), the application cut-off is 14 July 2026, the connection guarantee has jumped from 5% to 20%, and a separate €20/kW participation guarantee is being introduced for the autumn auctions. On top of that, the political situation around an even tougher government emergency ordinance has just changed, which matters for anyone trying to plan around it.
If you are sitting on a Romanian pipeline, whether it is a 5 MW BESS co-located with rooftop solar or a 400 MW utility cluster, the next two months are a re-audit window. Here is what changed, why it matters, and what we would be checking right now.
What is actually in force as of this week
There is more than one moving piece. Pulling them apart matters, because they have different legal weights and different deadlines.
The auction methodology is live. ANRE approved the auction-based capacity allocation methodology in 2024, it came into force on 1 January 2026, and Transelectrica published its implementation procedure in October 2025. It applies to every new generation or storage facility of at least 5 MW, including capacity additions and BESS retrofits at existing sites. Auctions are annual, with 10-year allocation periods starting in the second year after the auction. Allocated capacity is reserved for the declared commissioning year plus five years; after that, it is automatically lost.
The first auction calendar (revised by Order 79) sits as follows. Transelectrica publishes available grid capacity by 30 June 2026. Capacity allocation applications must be submitted by 14 July 2026. DSOs forward applications to the TSO by 20 July. The eligibility list is finalised by 24 July. Global solution studies (covering both transmission above 110 kV and distribution at 110 kV and medium voltage) must be completed by 23 October. Daily auction sessions begin 30 October 2026.
The transition rule is the one most developers misread. Connection requests registered before 1 January 2026 keep the old regime only if both conditions hold: the solution study was submitted by 31 December 2025, AND the ATR is issued by 30 June 2026. If you cleared the first hurdle but miss the second, you fall back into the new auction system. If you did not submit the solution study by year-end 2025, grid operators are required to reimburse what you paid for the study by 1 March 2026, and you are in the auction pool.
The guarantee structure has hardened, and is still moving. ANRE confirmed on 24 April 2026 that the connection guarantee rises from 5% to 20% of the connection tariff, payable after the connection application is submitted and the solution study is approved. A separate €20/kW deposit is required to participate in the autumn capacity allocation auctions, released or executed at auction close. ANRE also signalled a €30/kW guarantee at the setting-up authorisation stage, but that piece sits on a different legal track and is now caught in political crosswinds (more on this below).
Tighter deadlines apply once you have an ATR. Developers must request signing of the connection agreement at least 45 days before ATR expiry. Missing documentation must be resubmitted at least 15 days before expiry. Extensions of the connection agreement are allowed only in 12-month increments, each requiring an additional 5% guarantee on the connection fee. Setting-up authorisations must be obtained within 12 months of signing the connection agreement, and within 18 months of the ATR date. Missing either window triggers ATR invalidation and forfeiture of the guarantee.
Why this is happening, in one paragraph
ANRE statistics tell the story bluntly. Of projects that posted the old 5% guarantee, only 12% reached a signed connection agreement, only 3% obtained building permits, and only about 1% reached all three milestones (connection agreement, building permit, setting-up authorisation). Prime Minister Ilie Bolojan stated in early April 2026 that ATRs totalling more than 78,000 MW had been issued, with another 30,000 MW in process, against a national consumption baseline of roughly 9,000 MW. Industry sources put the total pipeline closer to 81 GW. Less than 10% of allocated capacity, by the government’s own count, has translated into actual investment. The auction system, hardened guarantees, and tighter authorisation deadlines are the system’s attempt to clear that overhang without crushing serious developers along with the speculators.
The piece that got blocked this week (and what it means for planning)
On 4 May 2026, the outgoing Bolojan government adopted an Emergency Ordinance introducing a €30/kW guarantee at the setting-up authorisation stage. On 5 May, the government was dismissed via a no-confidence vote. The Legislative Council subsequently issued a negative opinion on the ordinance, and the act has not been published in the Official Gazette. As things stand, the ATR-related emergency ordinance is not in force, and an interim government cannot reissue it.
What this changes, in practical terms:
- The €30/kW setting-up authorisation guarantee, as a hard legal requirement, is on pause.
- The €20/kW auction participation guarantee and the 20% connection guarantee are advancing through ANRE’s own regulatory route (consultation closed 7 May 2026), and ANRE has signalled it will finalise these with industry input.
- The Transelectrica auction calendar (30 June, 14 July, 23 October, 30 October) sits on Order 79 and the underlying ANRE methodology, both of which remain in force.
In other words: the core auction architecture is live and on schedule. The most aggressive guarantee layer is in legal limbo. That gap will get closed, one way or another, by whichever government takes office, because the policy direction has cross-party momentum and an EU-level rationale. Plan for it to arrive in some form during 2026.
What to re-audit this week if you hold a Romanian pipeline
This is not legal advice, and projects vary enormously. But these are the questions every developer with a Romanian asset should be running through right now.
1. Where does each ATR sit on the 30 June 2026 cliff? For requests filed before 1 January 2026 with solution studies submitted by 31 December 2025, the question is whether your ATR will physically be issued before 30 June 2026. If not, you are in the auction pool. Move documentation now, not in May. If your ATR was already issued, focus shifts to the 12-month and 18-month authorisation deadlines.
2. Has your operator already reimbursed solution study costs? For pre-2026 requests without a December 2025 study, operators were required to reimburse by 1 March 2026. If that did not happen, raise it now. It is both a cash item and a documentation trail for future ANRE complaints.
3. Are your guarantees correctly sized for the new regime? A 5% guarantee on a connection tariff is no longer the operative number. Stress-test cash forecasts at 20%, with an extra 5% per 12-month extension, and budget €20/kW for auction participation if you intend to bid in October. For a 100 MW project, the auction deposit alone is €2 million.
4. Do you have a credible authorisation timeline? The 12-month signing window and 18-month setting-up authorisation window are now hard. Where environmental permits, AACR clearance for wind projects, or CFISD/CSAT approvals are the bottleneck, you need a documented mitigation plan. ANRE has consistently signalled that procedural delays outside the developer’s control are not, by default, a basis to extend.
5. Which auction zone are you actually in? Transelectrica will publish available capacity per zone on 30 June 2026, with global solution studies updated by 23 October. Capacity is not fungible across zones. The N-1 security criterion is being applied more strictly under the new regime, which means tender starting prices will reflect both N and N-1 reinforcement costs. The cheap zones of 2024 are not necessarily the cheap zones of late 2026.
6. Is your SPV structured for the new disclosure environment? The government published a list of more than 1,400 ATR holders. ANRE statistics on zero-turnover, zero-employee SPVs are now part of the public conversation. SPVs are perfectly legitimate vehicles, but the optics and the audit posture have changed. Make sure your project narrative, financing letters, EPC engagement, and land control documentation are organised and presentable.
7. For storage specifically, are you correctly classified? The auction regime explicitly covers BESS additions of 5 MW or more, including retrofits at existing generation sites. Co-located storage that was originally tucked under a generation ATR may need to be reassessed under the new framework, particularly if the storage component pushes the site across reinforcement thresholds.
The strategic picture for Romania
It is easy to read this as a Romania-specific story about speculative actors and regulatory cleanup. The more useful reading is that Romania is doing what mature European markets did several years earlier, and is doing it on a more compressed timeline.
The country has a 5 GW storage target by end-2026, was one of the few European PV markets to grow in 2025, has Aurora Energy Research projecting double-digit IRRs for BESS entering the market in 2026, and is sitting on grid congestion that is now expensive for everyone in the queue. Cleaning the speculative pipeline is not an attack on the renewables sector. It is the mechanism by which serious capital can actually find a path to commissioning.
Markets that go through this transition tend to emerge with fewer projects, larger projects, better-financed sponsors, and predictable timelines. That is what Romania is buying with the noise of the last six months. For developers and investors with real projects, real balance sheets, and real EPC partners, the new framework is broadly good news, even where it is uncomfortable in the short term.
Momentum Energy’s View
We have been close to the Romanian pipeline reform for the entire arc, from the August 2024 ANRE methodology, through the October 2025 Transelectrica implementation procedure, the Order 79 calendar revisions in late 2025, the March and April 2026 consultations, and the political turbulence of the last fortnight. Three observations seem worth flagging.
First, the auction architecture itself is not the risk. It is well-designed, aligned with how Spain, Great Britain, and other mature European markets have moved, and gives developers a clearer signal about cost and capacity than the old queue ever did. The 30 June and 14 July 2026 deadlines should be treated as fixed. Plan around them.
Second, the political layer is genuinely uncertain, but the direction is not. Whoever forms the next government will inherit an 80+ GW phantom pipeline and a binding 5 GW storage target. The €30/kW setting-up guarantee, or something close to it, will return. Developers who are betting that the reform fades are, in our view, mispricing the policy. The CfD auctions, the EU subsidy schemes, and the ANRE methodology are all pulling in the same direction.
Third, Romania remains, on the numbers, one of the most attractive places in Europe to deploy storage and well-structured renewables capital in 2026 and 2027. Double-digit modelled IRRs, a renewables build-out generating real merchant volatility, a country target that requires a 5x to 6x increase in operational storage in roughly 18 months, and a regulatory framework that is finally moving toward EU-grade predictability. The combination is unusual, and it favours operators who are organised enough to navigate the auction process competently. The opacity that protected weaker projects under the old regime is precisely what made the market harder for serious capital. Removing it is, on balance, good for everyone with a real project in the ground.
The week ahead is, very practically, a re-audit week. Pull your ATRs, check your deadlines against the 30 June and 14 July dates, recalculate your guarantee exposure at 20%, and map your zones against Transelectrica’s pending capacity publication. The developers who do this work now will be the ones bidding cleanly in October. The ones who do not will be reading about the auction outcomes in late November and wondering what happened.
