Second-phase selection for Đerdap 3 pumped storage
A consortium led by Bechtel UK Holdings International and including Turkey’s ENKA has been identified as the only applicant meeting Serbia’s requirements for the second phase of strategic-partner selection for the Đerdap 3 pumped-storage project. The announcement advances the group to continue in the strategic-partner process.
Serbia received responses to a June call from six groups. Other applicants named in the process include Voith Hydro, Fresh Development with Serbia’s LDS, Channell Commercial Corporation, Global TBM and Serbia’s Moravacem.
A government working group concluded that only the Bechtel-led consortium demonstrated the required US ownership, front-end engineering management, hydropower experience and delivery track record for energy infrastructure valued at more than €1 billion. The assessment was tied to eligibility requirements for moving into the next stage.
Scope remains subject to feasibility and engineering work
The selection decision does not constitute an EPC award. Key project parameters including installed capacity, reservoir configuration, number of units and construction cost are described as remaining subject to feasibility and engineering work.
Current official estimates place investment above €2.63 billion. Earlier concepts considered configurations ranging from approximately 1,200 MW to 2,400 MW.
The strategic-partner step is separated from a parallel documentation tender opened by Serbia. Bechtel and ENKA have secured the right to continue discussions, but Serbia has not committed construction funding, sovereign guarantees or a final technical design.
Documentation tender and cross-border coordination requirements
Serbia has opened a tender worth RSD625 million, or approximately €5.3 million, covering general design, preliminary feasibility study, special-purpose spatial plan and strategic environmental assessment for Đerdap 3. Applications are due by 20 August.
The documentation tender operates alongside the strategic-partner process rather than replacing it. Serbia’s approach also requires involvement of Romania because the plant would interact with the shared Iron Gates hydropower and navigation system.
A bankable structure would need to address ownership arrangements, market dispatch, water rights, cross-border operating procedures and revenue sources. Wholesale arbitrage alone is described as unlikely to finance a project above €2.6 billion.
Revenue stack considerations amid drought conditions
The source material indicates that capacity payments, balancing revenue and ancillary services could be required to support long-tenor debt financing. It also notes that potentially regulated availability income may be part of the financing framework.
The present drought is cited as reinforcing both sides of the investment case. Serbia is said to need flexibility able to replace evening imports and absorb future wind and solar surpluses.
The project design is expected to show that adequate water and reservoir capacity remain available during dry periods when electricity is most valuable. This requirement links operational performance assumptions to reservoir availability during drought conditions.
