A consortium led by Bechtel UK Holdings International and including Turkey’s ENKA has emerged as the only applicant meeting Serbia’s requirements for the second phase of strategic-partner selection for the Đerdap 3 pumped-storage project.
Six groups responded to the June call. The other applicants included Voith Hydro, Fresh Development with Serbia’s LDS, Channell Commercial Corporation, Global TBM and Serbia’s Moravacem. The government working group concluded that only the Bechtel-led consortium had demonstrated the required US ownership, front-end engineering management, hydropower experience and delivery of energy infrastructure worth more than €1 billion.
The decision is not an EPC award. Installed capacity, reservoir configuration, number of units and construction cost remain subject to feasibility and engineering work. Current official estimates place investment above €2.63 billion, while earlier concepts have considered configurations between approximately 1,200 MW and 2,400 MW.
Serbia has separately opened a RSD625 million, or approximately €5.3 million, tender for the general design, preliminary feasibility study, special-purpose spatial plan and strategic environmental assessment. Applications are due by 20 August.
The split between the strategic-partner process and the documentation tender is important. Bechtel and ENKA have secured the right to continue discussions, but Serbia has not committed construction funding, sovereign guarantees or a final technical design. Romania must also be involved because the plant would interact with the shared Iron Gates hydropower and navigation system.
A bankable structure would need to establish ownership, market dispatch, water rights, cross-border operating procedures and revenue sources. Wholesale arbitrage alone is unlikely to finance a project above €2.6 billion. Capacity payments, balancing revenue, ancillary services and potentially regulated availability income would be required to support long-tenor debt.
The present drought reinforces both sides of the investment case. Serbia urgently needs flexibility capable of replacing evening imports and absorbing future wind and solar surpluses. Yet the project’s design must demonstrate that adequate water and reservoir capacity remain available during precisely the dry periods when electricity is most valuable.
