A development site has traditionally been evaluated on the basis of land cost, permits, transport links and labour availability. Electricity access is rapidly becoming just as important. A data centre, battery manufacturing plant, electric-boiler facility or advanced industrial project may require tens of megawatts of reliable capacity.
If the local grid cannot provide that capacity for five years, inexpensive land may have little practical value. Conversely, a less attractive location with a secured high-voltage connection can support investment almost immediately. The result is a fundamental shift in development economics: the megawatt is becoming a real-estate attribute.
This scarcity is largely the result of mismatched timelines. Digital and industrial investors can make location decisions within months, while transmission lines, substations and network reinforcements can take several years to plan, permit and construct.
Renewable developers are competing for export capacity, while batteries may need both import and export rights. As demand for connections rises, the queue itself becomes an economic asset, even in markets where connection rights cannot formally be traded.
How the asset is created
A credible grid-connection position is much more than submitting an application. It can include completed technical studies, agreed connection conditions, financial deposits, land rights for cables, reserved substation bays, funded network reinforcement and a binding energisation timetable.
Each completed step reduces development risk.
This distinction is becoming particularly important in mergers and acquisitions. Buyers need to distinguish between a nominal connection reservation and genuinely deliverable capacity. A project may appear advanced on a development pipeline while its actual connection remains uncertain if critical network reinforcement has not been financed or depends on future approvals.
Developers can also create value by securing electricity capacity before the final tenant, industrial process or technology has been selected. Industrial parks may build substations speculatively and market guaranteed megawatts as part of their infrastructure offering.
Data-centre developers are increasingly evaluating electricity availability before finalising site architecture, while renewable projects with mature connection positions can attract premiums even before construction begins because the scarce asset is often the right to inject or consume power, not the physical equipment itself.
Regional competition
The phenomenon is likely to be particularly visible around Athens, Bucharest, Budapest, Belgrade, Zagreb and Ljubljana, as well as renewable-rich transmission corridors and major logistics centres.
Greece’s growing data-centre pipeline illustrates how rapidly digital infrastructure can compete for grid capacity. Romania faces a combination of renewable and industrial growth, Hungary is expanding battery manufacturing, Serbia continues to attract industrial investment, while Croatia faces growing electricity demand linked to coastal development and broader economic activity.
For governments, this changes the meaning of investment incentives. Offering land, tax benefits and subsidies may not be enough if grid connection cannot be delivered within an investor’s global deployment timetable.
Investment-promotion agencies will increasingly need live information on available grid capacity, combined with closer coordination with transmission and distribution system operators.
Electricity infrastructure is therefore becoming part of the marketing proposition for industrial sites.
Financial and regulatory implications
Lenders are also likely to treat grid-connection status as a core project-finance risk. A delayed connection can postpone revenue generation and trigger EPC disputes even when the project itself is technically complete.
Financing conditions should therefore verify the legal status of the connection, responsibility for network construction, potential curtailment arrangements and long-stop dates for energisation.
Valuers may also need to recognise the premium attached to secured electricity capacity while avoiding the risk of assigning excessive value to speculative positions in connection queues.
Regulators face the opposite challenge: capacity hoarding.
If developers can reserve large amounts of grid capacity cheaply and transfer projects between entities, connection queues can become crowded with speculative applications. Use-it-or-lose-it milestones, financial guarantees and transparent readiness criteria can help ensure that scarce capacity is allocated to projects capable of actually using it.
Flexible connection agreements can provide another solution. Projects may be allowed to connect earlier in exchange for accepting limited curtailment during periods of network congestion.
The new development hierarchy
The hierarchy of project development is changing. Land without power is increasingly just land. Power rights without a credible project may be little more than an option.
The most valuable combination is a permitted site, a bankable grid connection and a flexible operating model capable of functioning within network constraints.
Southeast Europe’s next wave of digital and industrial investment will therefore be shaped by substations and transmission capacity almost as much as by tax policy and labour costs.
Connection rights will increasingly influence M&A valuations, project finance, industrial-site pricing and regional competitiveness.
After a decade in which the energy sector focused heavily on securing generation megawatts, the scarce asset of the next decade may be something different: the legal, technical and physical right to use those megawatts where and when they are needed.
