Across Romania, 113.7 GW of renewable projects hold valid Technical Connection Approvals (ATRs). In Dobrogea and Banat, however, Transelectrica says the existing infrastructure can no longer accommodate additional capacity without further investment. The two statements are not contradictory. The first describes an administrative pipeline; the second describes a local, physical constraint on the grid. bvb.ro

This is the useful question behind the 113.7 GW figure: how many of these MW have a verifiable path to the grid, and who controls each bottleneck along that path? An ATR is neither energy production nor secured financing, nor a guarantee that a power plant will be commissioned on its declared date. It is a necessary connection stage, but only one of several.

ANRE’s snapshot as of 1 July 2026 includes 1,672 renewable projects of at least 1 MW. It is not an account of all connection demand in Romania: by the reporting definition, it excludes projects below 1 MW and should not be confused with installed capacity or with the energy that can be produced at a given hour.

A MW’s path: four thresholds, one physical test

ANRE’s data make it possible to read the pipeline as a sequence of thresholds. Each removes some uncertainty, but no administrative threshold alone is equivalent to a power plant injecting energy into the system.

Stage	Aggregate capacity	What it confirms	What remains unconfirmed
Valid ATR	113.7 GW	Approved export capacity and technical connection conditions	Financing, construction, all permits, a certain commissioning date and unrestricted operation
Connection contract	55.4 GW	A contractual commitment in the connection process	Completion of works and permitting
Contract plus building permit	33.8 GW	Completion of an important permitting threshold	Completed construction and the physical availability of export capacity
Contract, building permit and establishment authorisation	11.2 GW	The most advanced administrative subset in ANRE reporting	A guaranteed completion rate or a plant already connected

The final category represents around 9.9% of capacity with ATRs. This proportion shows that the pipeline narrows sharply as contractual obligations and permits arise; it does not show why each project stops. The gap may include recent projects, financing or permitting delays, capacity changes, land issues, delayed operator works, extensions or withdrawals. Aggregated data do not allow these causes to be broken down by project.

There is, however, positive information rather than merely a limitation: ANRE identifies 216 projects that have all three administrative thresholds and an estimated commissioning schedule between 2026 and 2035, totalling 10,759 MW. Almost 96% of the 11.2 GW at that final administrative stage therefore also have an estimated commissioning year in the reporting. The estimate is not confirmation of delivery, but it is more informative than the mere existence of an ATR.

What the 113.7 GW figure cannot tell us

It cannot demonstrate that the remaining projects are fictitious. But neither can it rule out withdrawal, financial deadlock or the retention of a project as an option in an attractive area. A stock statistic — how many MW are at a given stage on a particular date — does not show how long each project remains there, or how many leave the system through withdrawal, expiry, transfer or capacity reduction.

This is the decisive gap in the debate: without the age of ATRs, expiry dates, contractual deadlines and series of withdrawn or delayed projects, the public cannot distinguish between a project naturally in its first years of development and one that has been stalled for years. A regulator or operator seeking to demonstrate that the mechanism clears the pipeline must publish outflows, not only the list of projects that remain.

The map matters more than the total

A MW does not connect to “Romania”; it connects at a specific point on the transmission or distribution grid. What matters there is the capacity of lines and transformers, simultaneous generation in the area, local demand, flows between regions, interconnections and the system’s safety conditions. This is why two projects with the same technology and capacity can have radically different paths to connection.

Transelectrica has identified Dobrogea and Banat as regions already congested for the integration of new capacity under existing conditions. The company estimates that investments under way and planned for these two regions could add around 5,000 MW by 2027. This is projected capacity, conditional on the completion of the works, rather than confirmed spare capacity today. bvb.ro

What is publicly known: congestion is acknowledged in these two regions, and there is an estimate of future capacity. What is still insufficiently transparent in the aggregated data: how many MW have been requested, offered, contracted and connected in each area; what specific investment makes them possible; and the physical and financial status of that investment.

Transmission and distribution are not the same path

The Electricity Transmission Grid, operated by Transelectrica, links major generation and consumption areas and supports the operation of the system nationally. Distribution grids deliver electricity to end consumers and may likewise be the local constraint for a project. The 2026 allocation mechanism considers available capacity in both the transmission grid and the distribution grid; this means that a single national figure cannot replace analysis by area and grid node. transelectrica.ro

There is another material distinction. A project’s actual connection — the installation linking it to the grid — is not the same as the grid reinforcement or development needed for the area to absorb new capacity. Transelectrica’s procedure separates investments already included in operators’ plans from the additional development works needed to create the conditions for connection. In other words, a project may have a technical solution, while its timetable depends on infrastructure that still has to be designed, permitted and built. transelectrica.ro

The 30 October auction: what it tests before it delivers results

As of this analysis’s reference date, 2 October 2026, the first auction session had not yet taken place. As an exception for 2026, the procedure provides for sessions to begin on 30 October 2026. Consequently, there are not yet official results on allocated MW, prices, winners, signed contracts or works begun. transelectrica.ro

The auction does not, by itself, “unlock” the grid. It determines who receives capacity under the allocation mechanism and on what terms, including where capacity must be created through additional works. Its initial test is one of selection and information: it will show where demand exists, how much capacity can be offered, for which commissioning years and what infrastructure becomes a condition of access.

The rules impose a financial cost on participation. For 2026, the participation guarantee is €20,000 per MW requested. For a hypothetical 100 MW project, this means €2 million tied up as a participation guarantee. Separately, for relevant projects above 1 MW, the financial connection guarantee is 20% of the connection fee, excluding VAT. The two guarantees should not be confused: they have different calculation bases and apply at different points in the process. transelectrica.ro

This filter may make cheap capacity reservation less attractive. It does not automatically follow that it will select only sound projects: for small developers, local projects or new technologies, the same rule may raise the barrier to entry. The net effect must be measured after the first allocations, including through projects that withdraw, meet deadlines or forfeit guarantees.

Connected projects exist, but the data do not yet tell the whole story

The discussion of the pipeline should not create the impression that nothing is being built. On 20 August 2026, Transelectrica announced that more than 2,500 MW of new generation and storage capacity had been connected since the beginning of the year. This signals physical delivery, unlike the number of ATRs. However, the release does not provide a breakdown sufficient to turn the figure into an account of large-scale renewables, storage, transmission-grid connections or distribution-grid connections. bvb.ro

The correct conclusion is less spectacular, but more useful: Romania simultaneously has a very large administrative pipeline, capacity that is actually connecting and regional bottlenecks requiring works. The public-policy question is not whether one of these realities cancels out the others, but whether their pace converges.

The dashboard that would make the mechanism verifiable

After the 30 October 2026 session, the assessment should not stop at a press release on the winners. The following data should be published quarterly, using a stable and comparable methodology:

Public indicator	Who should publish it	Positive signal	Risk signal
MW requested, offered and allocated, by area and commissioning year	Transelectrica, using distribution-operator data	Differences explained by capacity and timetable	High demand, unclear supply or unallocated capacity without explanation
Existing capacity versus capacity created through additional works	Transelectrica and distribution operators	Every allocated MW has associated works and a deadline	Capacity available today is mixed with infrastructure promises
Physical and financial progress of reinforcement works	Transelectrica and distribution operators	Progress reported by project, with a revised deadline and reason for deviation	Only broad estimates of future capacity
Expired, withdrawn, transferred or extended ATRs and contracts	ANRE, based on operator reporting	Clear series of entries into and exits from the pipeline	Only the total stock is published, without project dynamics
MW connected on time and months of delay, separated by cause	ANRE and grid operators	Delays are transparently attributed to the developer or the operator	It is impossible to see who controls the bottleneck

The real performance standard is not how many MW entered a list, but how many MW became operational assets on time in the area for which they were allocated. Until then, the 113.7 GW remain an important signal of investment interest and pressure on the grid — not a forecast of the energy Romania will actually have available.

Frequently asked questions

Does an ATR guarantee that a project will be built?

No. The ATR sets the technical connection conditions and the approved export capacity. It does not confirm financing, the receipt of all permits, completion of works, compliance with the commissioning deadline or unrestricted operation.

Does the gap between 113.7 GW with ATRs and 11.2 GW at an advanced administrative stage mean the rest are speculative projects?

This conclusion cannot be drawn from aggregated data. The difference may include recent projects, permitting and financing delays, project changes, delayed grid works, extensions or withdrawals. A judgement requires data on age, expiries, withdrawals and delays for each project.

What is being auctioned on 30 October 2026?

The mechanism allocates grid capacity for connection, assessed through the overall study for the transmission and distribution grids. In some cases, access may depend on additional development works needed to create the technical conditions for connection.

Why is the national MW total not enough?

Because connection takes place at a specific point on the grid. Capacity depends on lines, substations, transformers, flows, demand and simultaneous generation in the area. One region may be congested even if capacity or projects exist elsewhere in the country.

What is the most relevant indicator after the auction?

MW connected on time, by area, together with the grid works on which they depended and delays separated between those attributable to the developer and those attributable to the operator. This measures the transition from an administrative entitlement to functioning infrastructure.
