South-East Europe’s electricity utilities have shifted from passive state monopolies to systemically influential corporates within their national economies. They act as suppliers of baseload stability, hard-currency earners via cross-border electricity trade, and vehicles for renewable-energy deployment. The same companies also function as quasi-sovereign financial institutions supporting domestic banking and capital-market ecosystems.
Across Serbia, Croatia, Romania, Bulgaria, Greece, Montenegro, Bosnia and Herzegovina, and North Macedonia, the 2023 to 2025 period shows a consistent pattern. Operational output is stabilising after post-crisis volatility. Profitability has returned in most large utilities, while investment intensity is rising as governments push accelerated decarbonisation and grid modernisation.
Serbia’s EPS returns to net export position
Elektroprivreda Srbije has moved from the crisis period of 2021–2022 into a stronger financial and operational position. Annual production again exceeds national consumption, with Serbia re-establishing itself as a structural net exporter of electricity. Coal remains the bulk of generation, supported by large hydro plants that stabilise the system under favourable hydrological conditions.
Over the last two years, earnings have returned to positive territory and liquidity has remained stable. The utility has increasingly financed capital investments from internal cash flow rather than emergency borrowing. EPS is now treated not only as an energy company but as a strategic national balance-sheet asset linked to inflation, industrial competitiveness, household stability and sovereign borrowing credibility.
Hydrology-driven earnings in Croatia’s HEP
Croatia’s Hrvatska elektroprivreda illustrates how hydro-dependent systems can see different earnings cycles. In hydrologically favourable years, Croatia shifts from net importer to net exporter, supported by higher export revenues and comfortable system margins. When rainfall weakens, the country returns to net imports and financial results contract accordingly.
Despite that variability, HEP remains fundamentally profitable. The company continues to expand its renewable and solar portfolios while keeping a relatively measured leverage profile. Its approach is described as gradual and disciplined decarbonisation without destabilising the balance sheet.
Romania’s Hidroelectrica and Electrica performance under regulation
Hidroelectrica is cited as one of the most profitable utilities in Europe based on a very large depreciated hydro fleet. Market prices continue to monetise its low-cost generation advantage. Electrica is presented alongside it through the role of Romania’s regulatory model for distribution.
The distribution framework is described as enabling steady cost recovery through tariffs and supporting predictable EBITDA performance. The Romanian utilities are characterised as producing steady dividend streams that fund major refurbishments. They also anchor grid-modernisation programmes tied to future renewable-energy absorption.
Nuclear and lignite economics in Bulgaria
Bulgaria’s power system is described as structurally different due to a centralised holding structure and generation dominated by nuclear and lignite-based assets. Profitability remains strong and dividends to the state budget are significant. The description links financial strength even for carbon-intensive portfolios to scale, regulated frameworks and a balanced generation mix including nuclear baseload.
Volatility exposure in Bosnia’s exporters
Bosnia and Herzegovina is described as showing volatility despite system-wide export status. The country remains one of the largest net electricity exporters in the Western Balkans, but individual utilities can swing sharply between profit and loss. Deteriorating hydrology or underperformance in lignite production are cited among key drivers.
The swings are linked not only to rainfall patterns but also to export-price dynamics, domestic tariff structures and rising environmental-compliance costs. Export status alone is described as not guaranteeing financial resilience for individual operators.
EPCG’s hydro dependence in Montenegro
Montenegro’s Elektroprivreda Crne Gore is characterised as another hydro-dominated system influenced by water inflows. In strong years the company delivers healthy profits and supports the state budget. In weak hydrological periods earnings compress sharply while imports rise.
Even with that sensitivity, EPCG is described as not financially distressed. It maintains liquidity and carries significant investment programmes. The company is also described as being in the middle of a major generation and environmental-compliance modernisation phase in decades.
North Macedonia’s ESM transition programme
North Macedonia’s Elektrani na Severna Makedonija remains strategically dominant domestically while facing a structural transition challenge. Lignite continues to form a critical element of supply for ESM’s operations. The company needs to maintain reliability while reducing environmental exposure.
It is also tasked with executing one of the most demanding transition investment programmes in the region. ESM is described as system-critical and policy-driven, with its performance tied to national market stability.
PPC restructuring and shift toward renewables in Greece
Greece’s Public Power Corporation is described as among the most transformed utilities in South-East Europe. It has completed restructuring, restored profitability, stabilised leverage and resumed dividends. PPC is also characterised as positioned for a regional role rather than operating solely as a narrow national company.
The generation mix is described as rapidly shifting toward renewables and flexible gas. This change is supported by a corporate strategy and financing framework resembling major Western European utilities more than Balkan incumbents.
Regional scale: generation volumes and installed capacity
Across South-East Europe, the structural picture is described as consistent on scale indicators. The region generates well over 150 TWh annually and controls between 30 GW and 40 GW of installed capacity. Export capability is maintained when hydrology is supportive.
The regional mix includes coal and lignite systems that remain powerful but increasingly exposed to environmental and market pressures. Hydro-rich systems are described as profitable yet vulnerable to climate variability. Larger utilities are said to produce hundreds of millions of euros in annual profits that enable self-financing of capital expenditure while reducing dependency on emergency debt.
The smaller hydro-dependent utilities are described as remaining more exposed while maintaining investment commitments considered essential for long-term security. For investors, lenders and policymakers, SEE utilities are characterised as central macro-economic anchors and execution vehicles for the transition across multi-billion-euro transformation programmes.
The stated factors affecting future value include hydrological stability, disciplined tariff regulation, timely execution of renewable capacity, and credible governance frameworks capable of managing transformation programmes without destabilising national economies.
