Elektroprivreda Srbije (EPS) is transitioning from a phase of strategic repositioning to a defined execution cycle, focusing on a series of hydro rehabilitation projects, utility-scale solar and storage initiatives, and a delayed pumped storage scheme. This shift forms the foundation of a multi-billion-euro transition program, characterized by a concentrated portfolio of capital-intensive assets that feature distinct financing structures, timelines, and risk profiles.
The transition strategy is supported by a capital envelope exceeding €3 billion by 2030, with over €2 billion allocated for renewable energy projects and approximately €1 billion earmarked for hydropower rehabilitation and expansion. EPS management has indicated that around €1.2 billion will be invested in renewable projects between 2026 and 2029, suggesting an accelerated investment approach rather than a gradual one.
This new phase is marked not only by its scale but also by its financing structure. EPS is moving away from a traditional state-centric capital model to a layered financing approach that includes multilateral funding, engineering-procurement-construction (EPC) backed delivery, and strategic partnerships. This evolution reflects a significant change in how the utility approaches its investments.
The hydropower rehabilitation segment is the most advanced within this portfolio, with projects already secured through financing agreements with institutions like the European Investment Bank. Key initiatives include the reconstruction of the Potpeć hydropower plant, estimated at €91 million, and the rehabilitation of Djerdap II, valued at around €90 million. These projects are categorized as low-risk investments aimed at extending operational life by up to 30 years while providing incremental capacity increases.
Additionally, the modernization of the Bistrica hydropower plant adds another €59 million to this segment. Collectively, these projects are designed to stabilize EPS’s transition strategy by ensuring that existing dispatchable capacity remains available as renewable energy sources are scaled up. Their significance lies in enhancing system reliability and flexibility amid Serbia’s integration into European electricity markets.
In contrast, the largest investment initiative focuses on solar energy and battery storage. This program entails developing a 1,000 MWac solar portfolio alongside an additional 200 MW / 400 MWh battery storage system, with a total projected value between €1.4 billion and €1.6 billion. This ambitious rollout marks EPS’s most extensive renewable initiative to date. The incorporation of battery storage highlights the necessity of balancing capacity in an increasingly volatile market environment.
The program will unfold across six sites, with construction anticipated to commence in 2026. While it matches regional renewable efforts in scale, it presents heightened execution complexity due to the integration of storage systems and coordination across multiple sites.
Another key project is the Bistrica pumped storage hydropower initiative, now gaining momentum with planned capacity of approximately 650 MW and an estimated investment between €1 billion and €1.2 billion. Preparatory works are set to begin in 2026 following advancements in spatial planning and technical documentation involving international partners such as JICA.
Unlike the solar initiative, Bistrica emphasizes its strategic role in system balancing rather than immediate financial returns. Pumped storage technology is crucial for large-scale balancing over extended periods, especially as renewable energy penetration increases. However, it faces challenges related to lengthy development timelines and environmental permitting.
EPS has not abandoned thermal capacity in its investment strategy; a proposed gas-fired power plant near Niš with a capacity of 500 MW carries an estimated value of around €600 million. This project aims to ensure system security during the transition and is linked to broader regional energy cooperation initiatives.
However, this project presents different risks compared to hydro or renewables due to its dependence on gas supply conditions and price fluctuations amidst evolving carbon regulations. While included in EPS’s official investment narrative, it lags behind other projects in terms of financing readiness.
Completed projects serve as benchmarks for assessing EPS’s cost base and delivery capabilities. The Kostolac wind farm (66 MW) represents an investment of approximately €144 million, equating to around €2.18 million per MW. Similarly, the Petka solar plant (9.75 MW), with an investment of about €12 million, falls within a cost range of approximately €1.2 million per MW.
These completed assets signify EPS’s entry into renewable generation beyond hydropower while providing operational data that will inform future larger-scale solar initiatives.
Overall, EPS’s investment portfolio reveals a structured transition strategy focused on three pillars: stabilizing existing hydropower assets for reliability, rapidly deploying solar capacity enhanced by battery storage for flexibility, and developing long-duration storage alongside flexible thermal capacity for system balance during volatility.
The concentration within this portfolio indicates EPS’s commitment to large-scale capital-intensive assets rather than diversifying across numerous smaller initiatives. This strategy simplifies decision-making but increases execution risks; delays or underperformance in any project could have significant implications across the system.
Moreover, this new financing structure introduces dynamics that emphasize bankability discipline where projects must adhere to technical standards alongside financial and environmental criteria aligned with European frameworks.
As Serbia approaches closer integration with EU electricity markets—with exposure to negative pricing and increased cross-border flows—the timing of these investments becomes crucial for both EPS’s transformation and the stability of Serbia’s power system.
The next two to three years will be pivotal as construction activities are expected to ramp up from 2026 onwards. The successful transition from planning to execution will test EPS’s ability to manage large infrastructure projects simultaneously while shaping Serbia’s energy sector trajectory into the next decade amidst evolving challenges.
