Romania begins auctioning scarce grid capacity, adding new costs to electricity investment

Romania is introducing competitive auctions for electricity-grid access connection capacity, turning access to transmission and distribution networks into an explicitly priced investment requirement. The change may affect project valuations, financing costs and the market for existing electricity assets. National transmission operator Transelectrica will hold the first competitive capacity-allocation sessions on October 30, offering 1,566 MW of future capacity in designated network zones, subject to additional network development.

Published opening prices range from approximately €136,000 to €719,000 per MW, depending on location, connection year and network classification; winning bids may be higher. The capacity on offer is concentrated in 2032–2037, underlining the long waits facing some categories of new electricity projects. Romania is moving away from the traditional first-come, first-served approach for qualifying projects and towards a system in which developers must show both willingness and financial capacity to pay for scarce network access.

The change reaches beyond grid engineering for infrastructure investors. A project’s connection rights, the contractual security of those rights and the date electricity can physically enter the network are becoming central to its financial value. These factors are increasingly relevant to project development and investment decisions.

Capacity availability and prices vary by zone and year

Transelectrica’s published allocation schedule covers 2028–2037, but the latest assessment shows no capacity available through the new auction mechanism before 2032. The operator is offering 412 MW in 2032, 80 MW in 2035, 862 MW in 2036 and 212 MW in 2037. The 2036 allocation is the largest, representing approximately 55% of the total capacity on offer.

These figures cover capacity made available through identified additional network development works. They do not mean that Romania has prohibited all new electricity connections before 2032. Existing connection approvals, other applicable connection procedures and projects outside the auction mechanism must be considered separately.

The new system divides the electricity network into 10 allocation zones, each with its own capacity volumes and opening prices. The lowest published starting price is approximately €136,000/MW for capacity in Zone D in 2036. The highest is approximately €719,000/MW for a different network-category allocation in Zone D in 2037.

The prices show how network-capacity economics can differ, but they are not directly comparable options for the same project. At those respective opening prices, a hypothetical 100 MW development would face a capacity-allocation cost of approximately €13.6 million or €71.9 million, before additional connection expenditure. This calculation illustrates possible financial exposure, not the actual cost of a specific eligible project.

Developers must fund their own substations, connection lines, installation works and other applicable infrastructure separately. The winning bid is an additional cost for securing capacity under the allocation mechanism, not an all-inclusive construction budget. The project’s total costs therefore extend beyond the amount paid in the auction.

Guarantees add financial requirements for bidders

The new mechanism also imposes stricter financial requirements. Qualifying developers had to provide a participation guarantee of €20,000/MW when submitting applications. For a 100 MW project, that amounts to €2 million in committed financial security before entry into the competitive bidding process.

Under Transelectrica’s procedures, unsuccessful bidders can recover their participation guarantees. Successful participants recover theirs after completing the prescribed contractual steps. They must also provide an additional financial guarantee equal to 1% of the allocation contract value before finalising their capacity-allocation agreements.

Failure to sign the required agreement and provide the prescribed guarantee by the applicable deadline can lead to the loss of allocated capacity and enforcement of the participation guarantee. The requirements are intended to deter applications from developers without sufficient financial resources or credible implementation plans. They also create additional liquidity needs for legitimate investors.

For project-finance banks, the auction adds an expenditure category to be assessed alongside land acquisition, environmental approvals, construction, equipment procurement and conventional connection costs. The challenge is particularly significant for projects expecting commercial operation six to eleven years in the future. Long development periods expose investors to higher financing costs, regulatory changes, equipment-price fluctuations and uncertainty about future electricity-market revenues.

A project that appears profitable before connection-rights expenditure may become economically unattractive once the auction price and additional development costs are included. The new costs must therefore be considered before a project reaches financial close. Investors also face the timing implications of committing funds well before construction or electricity delivery.

Romgaz and private developers submit applications

The initial application phase attracted 12 projects representing 491 MW, according to published Transelectrica application data. Applicants include Romanian state-controlled energy producer Romgaz, which submitted proposals for two photovoltaic projects with storage, each rated at 20 MW, and a 100 MW standalone storage installation near Iernut. Other applicants include companies linked to Turkish investment groups.

Energy Capital Group, associated with the Güris group, submitted a 51 MW storage project. Hessmaier, linked to the FIBA group, registered several proposed generation and storage developments. The applications span different technologies, locations and intended commissioning dates, and show that established energy companies and private investors are examining the new framework.

Applications do not amount to completed investments, financing commitments or awarded connection rights. Nor can the 491 MW of initial requested capacity be compared directly with the 1,566 MW offered across different zones and years to determine whether individual auctions are oversubscribed. A project may need capacity in a location or year where the relevant allocation is unavailable, even if capacity exists elsewhere in the system.

The allocation process is scheduled to run on successive working days until November 12, with separate sessions for the relevant allocation years. The key issue is whether technically suitable capacity can be matched with projects willing to pay the required price and accept the resulting implementation timetable. As bidding begins, final prices, winning allocations and successful contracts have yet to be established.

Existing connection rights may affect asset valuations

Competitive allocation creates a distinction between projects with established grid-access arrangements and those still seeking connection capacity. An operating installation with secure injection rights and proven physical access to the electricity system may have a different risk profile from an otherwise comparable development that needs a future auction award. That difference could become more apparent in acquisitions, refinancing and project-portfolio valuations.

Investors acquiring electricity assets will increasingly need to check the legal validity, technical scope and contractual restrictions of their grid-connection arrangements. Relevant matters include permitted export capacity, the connection date, the validity of technical approvals, required reinforcement works and conditions governing changes in ownership or project configuration. Connection approvals should not be treated as freely transferable financial instruments: their value depends on the applicable legal framework, contractual provisions and technical obligations.

Even so, scarcity creates the potential for a commercial premium on projects able to demonstrate reliable, enforceable and timely network access. Investment funds may shift towards acquiring advanced projects with completed permits and credible grid rights rather than large early-stage development pipelines. For banks, a valid connection position could become more important in collateral assessment and project due diligence, although it cannot replace a bankable revenue model.

The market may consequently place greater value on demonstrated deliverability than on announced installed capacity. A future connection that depends on several network reinforcement projects also creates technical and scheduling dependencies beyond a developer’s immediate control. Banks may require more detailed independent-engineering assessments and stronger contractual protection before accepting proposed commissioning dates.

Grid access reshapes financing and development decisions

Infrastructure lenders generally assess repayment capacity using construction expenditure, projected electricity revenues, operating costs, debt-service obligations and downside scenarios. The cost of network capacity must now be included in the capital budget before financial close. The timing matters because committing substantial funds years before construction or electricity delivery extends the period without operating income.

Investment committees will need to distinguish the price paid to secure an allocation from the cost of physical connection, the cost of financing the development period and the probability of completing the project on schedule. The auction could also create demand for specialist advisory services in grid-rights due diligence, capacity-allocation strategy, engineering assessment and project restructuring. Developers may need to reconsider planned connection locations, capacity sizes or ownership structures when auction costs exceed what their underlying projects can support.

Romania’s approach provides a regulatory case study for the wider Southeast European electricity market. Serbia faces substantial pressure on transmission connection capacity and growing uncertainty over the timing of access for new projects, but it has not introduced an equivalent general competitive auction regime for transmission connection rights. The Romanian experience illustrates how scarce grid capacity could increasingly affect the financing and valuation of electricity investments.

For Serbia’s independent power producers, acquisition targets and infrastructure lenders, the practical issue is the cost and reliability of securing a deliverable grid connection. Montenegro faces a different challenge because its electricity system and domestic investment market are smaller. In Montenegro, the timing and technical conditions of grid access can strongly influence the economics of individual projects.

A competitive capacity-pricing system may not suit every network or market structure. Romania’s framework nevertheless provides a reference for assessing transparent allocation, financial guarantees and the management of speculative connection applications. Comparable questions arise in Bulgaria, Croatia and North Macedonia, where developers must reconcile investment plans with limited network availability and evolving technical requirements.

For regional investors active in several electricity markets, connection rights may become a substantial and unevenly priced part of infrastructure expenditure. Romania’s first capacity auction marks a structural change in the relationship between electricity infrastructure developers and the transmission network. Investment discussions have historically focused on technology costs, financing conditions and expected electricity-market revenues; the competitive allocation system adds a measurable cost for obtaining network access at a particular location and date.

The system’s effectiveness will depend on whether the auction attracts credible projects, establishes commercially sustainable prices and helps turn planned network reinforcement into operational capacity. High opening prices and distant connection dates could strengthen financial discipline in the development market, but could also discourage otherwise viable investments. The first results will show whether developers accept the costs and whether the available allocations match actual demand.

For lenders and infrastructure investors across Southeast Europe, the Romanian reform provides an early indication of a broader change in electricity investment economics. Grid connection is becoming a separately priced investment requirement that can determine whether an electricity project is financially viable, rather than simply a technical milestone before construction. As competition for network access intensifies, an electricity asset’s value will depend not only on how much power it can produce, but also on when and where that power can reach the market and under what enforceable conditions.
