EPS shifts from planning to execution as €3bn transition plan concentrates on a few major projects

Elektroprivreda Srbije (EPS) is moving from a prolonged period of strategic repositioning into what increasingly looks like a defined execution cycle. Rather than spreading capital across dozens of smaller initiatives, the utility’s transition programme has taken shape around a concentrated set of capital-intensive assets—each with different financing structures, timelines and risk profiles—raising both the stakes and the scrutiny for investors.

A €3bn envelope framed for renewables and hydropower rehabilitation

At the centre of EPS’s shift is a capital envelope framed at more than €3 billion by 2030. Within that total, EPS has directed over €2 billion toward renewables, alongside approximately €1 billion allocated to hydropower rehabilitation and expansion. In the near term, management points to roughly €1.2 billion in renewable investments between 2026 and 2029, indicating that the next investment cycle will be front-loaded rather than gradual.

Financing structure changes: multilateral funding and partnerships

What distinguishes this phase is not only scale but structure. EPS is no longer relying solely on balance-sheet-driven investments. The pipeline instead reflects a layered financing model combining multilateral funding, EPC-backed turnkey delivery and strategic partnerships—signalling a clear departure from the utility’s historically state-centric capital model.

Hydro rehabilitation leads with bankable frameworks

The most advanced segment sits in hydropower rehabilitation, where projects are anchored in financing frameworks agreed with institutions such as the European Investment Bank. The reconstruction and extension of Potpeć hydropower plant totals €91 million, while the rehabilitation of Djerdap II is estimated at around €90 million—both positioned as lower-risk lifetime-extension investments that extend operational life by up to 30 years while delivering incremental capacity increases.

A third element, modernization of the Bistrica hydropower plant, adds about €59 million. Together, these projects are described as forming a stabilizing base for EPS’s transition strategy by keeping dispatchable capacity available as intermittent renewables are scaled up—less about expansion for its own sake than about system reliability and flexibility amid Serbia’s move toward deeper integration with European electricity markets.

Solar-plus-storage becomes EPS’s largest single bet

The largest initiative is EPS’s solar and battery storage programme: a 1,000 MWac solar portfolio paired with 200 MW / 400 MWh of battery storage. With an estimated value of €1.4–€1.6 billion, it is described as the most ambitious renewable rollout ever undertaken by EPS.

The inclusion of battery storage reflects an acknowledgement that generation capacity alone is insufficient without balancing capability in a market increasingly exposed to price volatility and negative pricing dynamics. The programme will be executed across six locations and is expected to enter its main construction phase in 2026.

While comparable in scale to regional renewable programmes, EPS’s approach is said to carry materially higher execution complexity because it integrates storage, coordinates multiple sites and aligns with grid infrastructure. As a result, even though the project is considered investable, it remains operationally complex and not yet fully de-risked.

Bistrica pumped storage gains momentum but remains timeline-sensitive

Alongside solar sits Bistrica pumped storage hydropower—a long-discussed asset now gaining tangible momentum. Planned capacity is approximately 650 MW with an estimated investment value of €1–1.2 billion. Preparatory works are expected to begin in 2026 after progress on spatial planning and technical documentation, including involvement from international partners such as JICA.

Bistrica’s role is framed primarily as strategic system support rather than immediate financial returns. Pumped storage is described as one of the few technologies capable of providing large-scale balancing over extended periods, with value expected to rise as renewable penetration increases. However, it faces inherent exposure to long development timelines, environmental permitting challenges and complex civil engineering risks—placing it between conceptual planning and fully bankable execution.

Gas capacity remains part of system-security logic

Thermal generation has not been removed from EPS’s investment logic either. A proposed 500 MW gas-fired power plant near Niš carries an estimated value of around €600 million and illustrates how EPS intends to maintain system security during the transition. The project is linked to broader regional energy cooperation discussions that include potential involvement from Azerbaijan.

Its risk profile differs from hydro and renewables: economics depend on gas supply conditions, price volatility and an evolving regulatory environment around carbon emissions. It also appears less advanced on financing structure and project development than other assets in terms of execution readiness.

Completed wind and solar projects offer cost benchmarks

EPS’s completed projects provide a reference point for understanding its cost base and delivery capability. The 66 MW Kostolac wind farm required approximately €144 million in investment value, implying about €2.18 million per MW—reflecting first-of-kind costs alongside site-specific infrastructure requirements. The 9.75 MW Petka solar plant totals roughly €12 million, corresponding to about €1.2 million per MW for a more conventional solar benchmark.

While these completed assets are modest relative to planned scale changes ahead for EPS, they signal entry into renewable generation beyond hydropower and generate early operational data that can inform the much larger solar rollout now planned.

Concentration improves focus but amplifies execution risk

Taken together, EPS’s portfolio reflects a layered transition strategy built on three pillars: stabilizing existing hydropower through rehabilitation; deploying solar capacity supported by battery storage; and developing long-duration storage alongside flexible thermal capacity to balance the system during volatility.

The portfolio’s concentration stands out: rather than diversifying across many smaller projects, EPS effectively relies on a handful of large infrastructure bets. That can simplify strategic direction but also amplifies execution risk—delays or underperformance in any single project could have system-wide implications given their centrality to reliability during Serbia’s market evolution.

Execution timing becomes critical as EU market integration deepens

The financing shift toward multilateral lenders, international partners and structured project delivery introduces another dynamic: projects must meet technical goals while also satisfying financial and environmental standards aligned with European frameworks—an added discipline that may shape how quickly assets reach bankable status.

As Serbia moves toward closer integration with EU electricity markets—including exposure to negative pricing signals increased cross-border flows—the timing of these investments becomes critical. With construction expected to accelerate from 2026 onward, the next two to three years will test whether EPS can manage multiple large-scale projects in parallel while balancing legacy assets against an increasingly complex—and capital-intensive—future for the Serbian power system.
