Elektroprivreda Srbije is moving from a prolonged period of strategic repositioning into what increasingly resembles a defined execution cycle, with a cluster of hydro rehabilitation projects, a utility-scale solar and storage platform, and a long-delayed pumped storage scheme now forming the backbone of a multi-billion-euro transition programme. What has emerged over the past three years is not a broad pipeline of dozens of projects, but a concentrated portfolio of capital-intensive assets, each carrying distinct financing structures, timelines and risk profiles.
At the centre of the shift is a capital envelope that EPS has framed at more than €3 billion by 2030, with over €2 billion directed toward renewables and approximately €1 billion allocated to hydropower rehabilitation and expansion. Within a shorter horizon, management has pointed to roughly €1.2 billion in renewable investments between 2026 and 2029, signalling that the next investment cycle will be front-loaded rather than gradual.
What distinguishes this phase is not just scale, but structure. EPS is no longer relying solely on balance-sheet-driven investments. Instead, the pipeline reflects a layered financing model combining multilateral funding, EPC-backed turnkey delivery, and strategic partnerships, marking a clear departure from the utility’s historically state-centric capital model.
The most advanced segment of the portfolio sits in hydropower rehabilitation, where projects are already anchored in financing frameworks agreed with institutions such as the European Investment Bank. The reconstruction and extension of Potpeć hydropower plant, with a total investment of €91 million, alongside the rehabilitation of Djerdap II at around €90 million, represent the lowest-risk segment of the current pipeline. These are not greenfield projects but lifetime-extension investments, delivering incremental capacity increases while extending operational life by up to 30 years.
A third component, the modernization of the Bistrica hydropower plant, adds another €59 million to the rehabilitation portfolio. Collectively, these projects form a stabilizing base for EPS’s transition strategy, ensuring that existing dispatchable capacity remains available as intermittent renewables are scaled up. Their importance lies less in capacity expansion and more in system reliability and flexibility, particularly as Serbia prepares for deeper integration with European electricity markets.
In contrast, the largest single investment initiative is the solar and battery storage programme, structured as a 1,000 MWac solar portfolio with an additional 200 MW / 400 MWh of battery storage. With an estimated total value of €1.4–1.6 billion, this platform represents the most ambitious renewable rollout ever undertaken by EPS. The inclusion of battery storage is critical, reflecting a recognition that capacity alone is insufficient without balancing capability, especially in a market environment that is increasingly exposed to price volatility and negative pricing dynamics.
The programme is structured as a multi-site development, spanning six locations, and is expected to enter its main construction phase in 2026. While the scale is comparable to regional renewable programmes, its execution complexity is significantly higher. The integration of storage, coordination of multiple sites, and alignment with grid infrastructure introduce risks that are materially different from standalone solar projects. As a result, while the project is clearly investable, it remains operationally complex and not yet fully de-risked.
Alongside this programme sits the Bistrica pumped storage hydropower project, a long-discussed asset that is now gaining tangible momentum. With planned capacity of approximately 650 MW and an estimated investment value of €1–1.2 billion, Bistrica is positioned as Serbia’s primary long-duration storage solution. Preparatory works are expected to begin in 2026, following progress on spatial planning and technical documentation, including involvement from international partners such as JICA.
Unlike the solar programme, Bistrica is defined by its strategic system role rather than immediate financial returns. Pumped storage remains one of the few technologies capable of providing large-scale balancing over extended periods, and its value will increase as renewable penetration rises. However, the project is inherently exposed to long development timelines, environmental permitting challenges, and complex civil engineering risks. It therefore occupies a middle ground between conceptual planning and fully bankable execution.
Thermal capacity, meanwhile, has not disappeared from EPS’s investment logic. A proposed 500 MW gas-fired power plant near Niš, with an estimated value of around €600 million, illustrates the utility’s approach to maintaining system security during the transition. Positioned as a flexible generation asset, the project is tied to broader regional energy cooperation, including potential involvement from Azerbaijan.
Yet this project carries a different risk profile from both hydro and renewables. Its economics depend on gas supply conditions, price volatility, and the evolving regulatory environment around carbon emissions. While it remains part of the official investment narrative, it is notably less advanced in terms of financing structure and project development, placing it behind other assets in execution readiness.
Completed projects provide a useful benchmark for understanding EPS’s cost base and delivery capability. The 66 MW Kostolac wind farm, with an investment value of approximately €144 million, implies a cost of around €2.18 million per MW, reflecting both first-of-kind costs and site-specific infrastructure requirements. Similarly, the 9.75 MW Petka solar plant, at roughly €12 million, aligns with a cost range of about €1.2 million per MW, offering a more conventional solar benchmark.
These completed assets are modest in scale but significant in signalling EPS’s entry into renewable generation beyond hydropower. They also provide early operational data that will inform the much larger solar rollout now planned.
Taken together, the EPS investment portfolio reveals a layered transition strategy built on three pillars. The first is the stabilization and extension of existing hydropower assets, ensuring system reliability. The second is the rapid deployment of solar capacity supported by battery storage, providing new generation and flexibility. The third is the development of long-duration storage and flexible thermal capacity to balance the system during periods of volatility.
What is striking is the degree of concentration within the portfolio. Rather than diversifying across numerous smaller projects, EPS is effectively betting on a handful of large, capital-intensive assets. This approach simplifies strategic direction but amplifies execution risk, as delays or underperformance in any single project could have system-wide implications.
At the same time, the financing structure introduces a new dynamic. The reliance on multilateral lenders, international partners, and structured project delivery suggests a gradual shift toward bankability discipline, where projects must meet not only technical and strategic criteria but also financial and environmental standards aligned with European frameworks.
As Serbia moves toward closer integration with EU electricity markets, including exposure to negative pricing and increased cross-border flows, the timing of these investments becomes critical. The ability of EPS to deliver on its announced pipeline will determine not only its own transformation but also the stability and competitiveness of the Serbian power system.
The next two to three years will therefore be decisive. With construction expected to accelerate from 2026 onward, the transition from planning to execution will test EPS’s capacity to manage large-scale infrastructure projects in parallel. The outcome will shape the trajectory of Serbia’s energy sector well into the next decade, as the utility attempts to balance legacy assets with an increasingly complex and capital-intensive future.
