Over a 30-year operating horizon, the utilisation profile of the new storage capacity in Smederevo will be shaped less by short-term fuel cycles and more by structural demand shifts. Under a base-case scenario where diesel demand in Serbia declines gradually by 1.5–2.0 percent per year after 2030, consistent with partial electrification of transport and efficiency gains, utilisation of strategic storage remains economically defensible through the mid-2040s. In this case, average tank utilisation would still exceed 65–70 percent, sufficient to justify ongoing operating costs and maintenance investment.
In a faster-transition scenario, where diesel demand contracts by 3–4 percent annually after 2035 due to accelerated electrification of freight corridors, stricter vehicle standards, and modal shift toward rail, utilisation could fall below 50 percent by the early 2040s. At that level, storage assets retain system value for emergency preparedness but begin to resemble policy-mandated infrastructure rather than economically optimised capacity. The key stranded-asset risk does not lie in physical obsolescence, but in declining marginal utility relative to carrying costs, especially if interest rates and fuel-price volatility remain elevated.
Governance of strategic reserves therefore becomes critical. Serbia currently relies predominantly on a state-held reserve model, where public authorities finance, own, and manage physical stocks. This model maximises control and crisis responsiveness but concentrates financial and operational risk on the public balance sheet. By contrast, many EU member states operate hybrid or industry-obligated systems, where refiners, importers, and distributors are mandated to hold minimum stocks, either physically or through ticketing arrangements with storage operators.
A gradual transition toward a hybrid reserve framework could materially reduce fiscal exposure. Under such a model, the Smederevo facility could remain state-owned while portions of capacity are leased to market participants under compulsory stockholding obligations. This would improve cost recovery, stabilise utilisation rates, and embed storage infrastructure more firmly into commercial fuel flows, without compromising emergency access rights for the state.
Alignment with Serbia’s broader energy-transition roadmap is the final—and most delicate—dimension. Strategic oil storage must increasingly coexist with policies aimed at reducing fossil-fuel intensity in industry and transport. The practical solution is not premature divestment, but designing optionality. Storage sites such as Smederevo can be technically prepared, at modest incremental cost, for future handling of advanced biofuels or synthetic diesel blends, preserving relevance beyond peak fossil-diesel demand.
At the same time, policymakers must avoid over-expansion. Each additional tonne of storage built after the mid-2020s carries higher long-term utilisation risk. The rational path is therefore capacity consolidation and optimisation, rather than continuous expansion, combined with parallel investment in rail freight electrification, logistics efficiency, and demand-side reduction measures. In this framework, oil-product storage becomes a stabilising backstop during transition, not a growth asset.
Smederevo project fits best within a managed-decline paradigm: a necessary, disciplined investment that secures energy supply through a volatile transition period, while remaining flexible enough to avoid becoming a stranded symbol of outdated energy policy. The success of this approach will depend less on engineering execution—which is already largely complete—and more on governance choices made over the next decade.
