In the previous two articles of the How the Giants Do It series, we established that a country’s power system is nothing more than the materialized reflection of its macroeconomic architecture and geographical realities. When these factors are respected, we achieve a healthy economy and a harmonious national production mix that strengthens the overall power grid and guarantees national sovereignty in every sense.

In this article, we will dissect the Balkan region in detail. When analyzing the power systems of this complex geographical and political space, superficial observers and Brussels technocrats most frequently fall into the trap of nominal percentages and the proclaimed „green agenda“. Even some domestic experts, knowingly or unknowingly, fall into this very same trap.

However, a deep engineering and techno-economic analysis reveals diametrically opposed economic organisms operating side by side. We will demonstrate that a comparative analysis of the Balkan states provides the ultimate proof of fundamental power engineering laws: energy uniformity is a dangerous illusion, and imposing universal transition templates without respecting the physics of the local space and economic drivers leads directly to economic collapse.

Macroeconomic Architecture and Energy Demand

To understand why neighboring countries have radically different energy needs, we must return to the foundational parameter: the energy intensity of the economy. When you compare nominal dollars and euros from tourism accounts on the Adriatic coast with tons of exported copper, steel, or heavy machinery components, the engineering conclusion is clear: economic structure dictates the physics of the system.

The thesis that any economy can be digitized or overnight transformed into a service-based one without preserving its baseload generation assets is pure fallacy. Behind every coastal hotel lies light, seasonal consumption. But behind every factory that funds the budget of an industrial nation stands a brutal, non-negotiable need for a stable baseload megawatt-hour (baseload). Successful energy policy does not tolerate the tyranny of uniformity, a fact best proven by a detailed engineering anatomy of the individual systems in the region.

Regional Anatomy: A Mosaic of Specifics vs. Unification

1. Serbia: Production-Industrial Realism and the Baseload Shield

• Macroeconomic Architecture: Serbia’s economy serves as the core production and industrial basin of the region. Its Gross Domestic Product (GDP) fundamentally depends on material production—the mining complex, metallurgy, manufacturing, rubber, plastics, and construction materials. These sectors sustain the country’s foreign trade balance, but their physics demands a massive, continuous, and affordable quantum of energy. Serbia’s economic organism requires a constant baseload shield. A fluctuating megawatt-hour that depends on weather conditions is utterly useless for Serbian industry, and high import dependence coupled with higher electricity prices resulting from it would be catastrophic.
• Geographical Anatomy of the Mix: Due to the geographical availability of resources, Serbia has justifiably and sovereignly anchored its system on its lignite basin, which still covers over 60% of the country’s baseload security. This coal is our energy shield, while the remainder is balanced by stable and powerful hydro capacities.
• Price profile (Households / Economy):Thanks to its reliance on domestic resources, prices for households are traditionally kept under control, standing at around 11.9 c€/kWh (including taxes). Industry pays a somewhat higher commercial price (around 12–14 c€/kWh excluding VAT, depending on the contract and free market pressures).
• LOLE and ENS Metrics: The LOLE index is kept below 3 hours per year. The expected annual ENS tends toward zero under normal operating conditions, as stable baseload generators constantly dampen internal system fluctuations. Serbia functions as the baseload stabilizer of the region.

2. Albania: Service-Rentier Architecture and Hydro-Monoculture Gambling

• Macroeconomic Architecture: The economic structure of Albania is structurally and geographically entirely different from Serbia’s. Its GDP predominantly relies on services, trade, and, above all, the explosive growth of tourism along the Adriatic and Ionian coasts. The Albanian economy does not smelt steel or process heavy metals on the scale that Serbia does. The service and tourism sectors consume electricity for lighting, air conditioning, and IT systems. Their footprint on the grid is seasonal and cyclical—consumption peaks during the summer months, while baseline industrial demand throughout the year is minimal.
• Geographical Anatomy of the Mix: Albania represents a unique and extreme phenomenon in Europe—its domestic electricity generation is nearly 100% dependent on hydro potential, primarily through cascades on the Drin River (HPP Fierza, Koman, and Vau i Dejes). From the perspective of the Brussels administration, Albania is a „green paradise“ and an example of successful 100% decarbonization. However, from the perspective of power system calculations and grid physics, the Albanian model is a textbook example of high-risk energy monoculture.
• Price profile (Households / Economy): For households, the price hovers around 9.5 c€/kWh (a heavily regulated social tariff), but the commercial sector faces extreme volatility. Large commercial consumers and coastal hotels, pushed onto the free market, pay import-driven market prices during dry months that frequently spike above 15–20 c€/kWh, directly threatening the profitability of the tourism sector.
• LOLE and ENS Metrics: In simulations of extremely unfavorable hydrological cycles, Albania’s internal LOLE index can escalate to over 50 or 100 hours per year, while the potential ENS rises to dozens of gigawatt-hours (GWh).

3. Croatia: Hybrid Tourism Model with an Import Buffer

• Macroeconomic Architecture: Similar to Albania, Croatia’s GDP structurally depends on Adriatic tourism, which generates extreme and sudden summer peaks in consumption due to air conditioning. On the other hand, the northern and continental parts of the country have retained light manufacturing and processing industries. This creates a hybrid energy demand—industry requires a stable baseload megawatt, while the coast demands seasonal flexibility and robustness.
• Geographical Anatomy of the Mix: Croatia has phased out coal-fired thermal capacities on its own territory. The system primarily relies on a strong but hydrologically variable hydro sector, the rapid growth of variable wind and solar plants, gas-fired capacities, and cross-border imports. Crucially, Croatia’s primary baseload shield lies outside its borders—it is its 50% co-ownership of the Krško Nuclear Power Plant in Slovenia.
• Price profile (Households / Economy): Croatia has a significantly higher, European-average price level. Households pay around 16.5 c€/kWh (thanks to state crisis mitigation packages), while industry faces prices ranging from 18 to as high as 22 c€/kWh. The high price for commercial consumers is a direct consequence of import dependence and the high costs of balancing variable renewable sources (wind/solar).
• LOLE and ENS Metrics: Due to the lack of stable baseload capacities on its own soil, Croatia experiences a moderately elevated LOLE index during critical summer months, thus functioning as an amortized importer.

4. Bosnia and Herzegovina: The Last Bastions of Lignite Realism

• Macroeconomic Architecture: Bosnia and Herzegovina (divided by entities but fully integrated electro-energetically) represents, alongside Serbia, the heavy industrial and resource basin of the Balkans. The economy directly relies on basic metallurgy (aluminum, steel), mining, and the defense industry. Such an economic organism demands a constant, uninterrupted supply of baseload energy 24/7.
• Geographical Anatomy of the Mix: The system is firmly built upon massive and stable thermal capacities utilizing domestic lignite (TPP Tuzla, Kakanj, Ugljevik, Gacko, Stanari) combined with excellent, high-accumulation hydro potential (cascades on the Neretva and Trebišnjica rivers). Thanks to this setup, BiH is the only permanent net exporter of electricity in the Balkans.
• Price profile (Households / Economy): Due to 100% self-sufficiency and large surpluses, BiH offers the cheapest electricity in the region. Households pay a mere 9.6 c€/kWh, while industry is secured by stable long-term contracts at a level of 8–10 c€/kWh. This low price for commercial consumers represents a key pillar of competitiveness for Bosnian heavy industry.
• LOLE and ENS Metrics: In ENTSO-E simulations, BiH boasts a LOLE that tends toward zero and an exceptionally stable ENS profile, while its baseload surpluses constantly extinguish energy crises in the rest of the region.

5. Bulgaria: The Nuclear and Regional Stabilization Shield

• Macroeconomic Architecture: Bulgaria features a large, industrial-manufacturing, and export-oriented economy with a massive processing, mechanical engineering, and mining sector. Its economy demands gargantuan volumes of energy to maintain its foreign trade balance and uninterruptedly supply its domestic factories.
• Geographical Anatomy of the Mix: Bulgaria possesses the most stable and sovereign mix in the region, thanks to the Kozloduy Nuclear Power Plant. Alongside this nuclear shield, the system relies heavily on the massive Marica Istok lignite basin and the rapid development of large-scale solar parks. Bulgaria stands as the electro-energetic anchor of Southeastern Europe.
• Price profile (Households / Economy): As a full EU member with a nuclear shield, Bulgaria manages to maintain one of the lowest prices in the Union. Households pay a stable 13.5 c€/kWh. For industry, the price is formed on a liquid domestic day-ahead market (IBEX) and averages around 11–13 c€/kWh, allowing Bulgarian industry to remain highly competitive in the European market.
• LOLE and ENS Metrics: Bulgaria’s national LOLE index is practically non-existent, sitting at less than 1 hour per year. Bulgaria’s nuclear-thermal megawatts are what physically, alongside the Serbian system, prevent a regional system collapse (blackout).

6. Greece: A Radical Experiment in the „Green Agenda“ and Gas Dependence

• Macroeconomic Architecture: Greece is a giant of the service-tourism model. During July and August, millions of tourists and extreme heatwaves push power consumption to the grid’s breaking point. Air conditioning and light consumption demand brutal amounts of energy in short time windows, while baseline industrial demand remains secondary.
• Geographical Anatomy of the Mix: Greece is a textbook example of political dictation from Brussels. It executed a rapid and aggressive decarbonization process, shutting down nearly all its moore powerful domestic lignite mines and power plants (Megalopoli and Ptolemaida). The system was shifted onto massive imported natural gas, wind farms, and vast solar capacities.
• Cenovni profil (Domaćinstva / Privreda): Greece pays the most expensive price for its transition in the Balkans. Households face prices exceeding 22–25 c€/kWh (depending on state subsidies and fluctuations), while commerce and industry pay brutal tariffs ranging from 24 to as high as 28 c€/kWh. These prices are a direct consequence of tying the electricity mix to volatile market prices for natural gas and the high costs of balancing the grid.
• LOLE and ENS Metrics: The Greek system is highly vulnerable. Under summer Dunkelflaute conditions, Greece’s internal LOLE spikes to dangerous levels, and the system is frantically saved by emergency imports.

7. North Macedonia: Chronic Import Dependence and Transition Vacuum

• Macroeconomic Architecture: The Macedonian economy is import-dependent and caught in a perpetual transition vacuum. Historically reliant on light and heavy industry (such as metallurgy), it currently suffers from a lack of domestic production to cover basic economic and industrial needs.
• Geographical Anatomy of the Mix: The Macedonian system is in a state of technological agony. Its main baseload pillar, REK Bitola (lignite), suffers from a critical shortage of domestic coal and aging equipment. The state is forced to import coal by trucks from its neighbors just to keep the plant running, while simultaneously experiencing an unregulated boom in private solar plants that the grid struggles to balance.
• Price profile (Households / Economy): Households pay a regulated price of around 11.6 c€/kWh. However, because domestic production does not meet demand, industry is entirely exposed to the free market and imports. Macedonian enterprises pay a high price of 15–18 c€/kWh, directly choking domestic small and medium enterprises and deterring foreign investors.
• LOLE and ENS Metrics: North Macedonia has one of the worst LOLE and ENS profiles in the region, literally surviving because it sits on a crucial transmission corridor and maintains good connections with the neighboring strong systems of Serbia and Bulgaria.

8. Montenegro: An Energy Balance via Subsea Cable

• Macroeconomic Architecture: Following the shutdown of the Podgorica Aluminum Plant (KAP) and the Nikšić Steelworks, Montenegro almost completely liquidated its heavy industry, transforming itself into a service-tourism economy. Consumption is highly seasonal—the coast „swallows“ energy in the summer, while the interior remains quiet during the winter.
• Geographical Anatomy of the Mix: The system is functionally boiled down to three points: the single thermal power plant, TPP Pljevlja, which covers over 40-50% of baseload security, and two large hydro power plants (HPP Perućica and HPP Piva), alongside newer wind farms (Krnovo, Možura). When TPP Pljevlja undergoes regular maintenance, or during a hydrological drought, Montenegro instantly loses its energy self-sufficiency.
• Price profile (Households / Economy): Montenegro maintains a stable pricing policy for both categories. Households pay around 9.9 c€/kWh, while commercial electricity is held at a similar, well-balanced level of around 10–11 c€/kWh. The reason for this is unique: Montenegro is the only country in the region where rates for citizens and industry are harmonized, thanks to smart balancing between the domestic TPP Pljevlja and energy exchanges via the subsea cable.
• LOLE and ENS Metrics: Montenegro’s LOLE exhibits sharp seasonal fluctuations, but thanks to the subsea cable to Italy and its connection with Serbia, Montenegro represents a well-nested system.

Techno-Economic Matrix of Balkan Power Systems

The following table summarizes the findings of this engineering analysis, clearly proving why a standardized, uniform energy mix across different territories is an impossible mission:

Metrics of Sovereignty and Pricing Realism

The comprehensive engineering analysis of the Balkan region yields an undeniable techno-economic dual axiom:

First, a low LOLE index, an expected ENS that tends toward zero, and complete independence from emergency imports are the exclusive privilege of systems that possess a strong, dispatchable, and stable baseload generation capacity (baseload). Power systems that have retained their structural realism—such as Serbia, Bosnia and Herzegovina, and Bulgaria—possess the necessary physical inertia and capacity to cushion internal fluctuations, thereby guaranteeing long-term national security and the stability of the entire region. This must be kept in mind when gradually retiring existing baseload capacities due to aging and regulatory pressures tied to decarbonization, ensuring that appropriate low-carbon replacement capacities in the form of nuclear power plants are developed in time.

Conversely, systems with a weak, degraded, or prematurely dismantled baseload generation are structurally condemned to critical spikes in their LOLE index, dangerous ENS risks, and a chronic, dramatic dependence on imports, which as a rule results in higher prices for industry. Whether driven by a high-risk hydro-monoculture or an aggressive „green agenda“ imposed by Brussels decrees, these vulnerable systems cannot survive by relying solely on local weather conditions. Their survival on the grid directly depends on the technical space, interconnections, and the stable baseload megawatt-hours generated by their sovereign neighbors.

Second, the structure of the production mix directly dictates the economic cost of an economy’s survival. Systems with strong baseload generation built on domestic resources (lignite, nuclear energy) succeed in securing stable and predictable prices for industry (between 8 and 13 c€/kWh), which directly protects domestic manufacturing and jobs. In contrast, import/transition systems and energy gamblers (such as Greece, Croatia, Albania, and North Macedonia) that have abandoned baseload security in favor of gas dependence or variable sources expose their commercial sectors to significantly higher prices ranging from 15 to as high as 28 c€/kWh. I must restate that while this might be justified for economies based on services, tourism, and hospitality, it is never viable for economies with pronounced industrial manufacturing.

This price disproportion clearly proves: abandoning baseload security under the guise of uniform transition templates brings not only technical instability (high LOLE and ENS) but also a direct loss of an economy’s competitive edge. For an industrial nation, moving from a sovereign baseload megawatt to a variable import-dependent model is not environmental progress—it is an energetic and economic trap.

The Superiority of Interconnection over Brussels Decrees

All analyzed states are part of the single synchronous zone of Continental Europe (ENTSO-E). It is precisely this superb cross-border technical connectivity and the solidarity of transmission grids—where the Serbian transmission system operator EMS plays a leading regional role alongside the Bulgarian system—that allows high-risk systems like the Albanian, Montenegrin, or North Macedonian ones to survive their structural shortcomings.

This provides direct evidence for the core thesis of this series: The salvation of the regional grid lies not in the administrative standardization of production mixes by Brussels, but in preserving sovereign technological profiles supported by high-capacity technical interconnection.

If Brussels were to force Serbia and Bosnia and Herzegovina into a rapid, mandatory decarbonization process—shutting down their thermal capacities before stable replacement assets (such as nuclear power plants) are constructed—the region would permanently lose its baseload stabilizer. In a scenario where the entire Balkans relies exclusively on variable and weather-dependent sources (wind, solar, and hydrological cycles), the first regional drought or winter Dunkelflaute (a prolonged period with no wind or sun across Central and Southeastern Europe) would trigger an immediate systemic collapse (blackout) of the entire Balkan peninsula.

Conclusion: A Lesson in Sovereignty

A comparison of the power systems in the Balkans unequivocally confirms that successful energy policy does not tolerate the tyranny of uniformity. What serves as a natural environment for a service-oriented, tourism-heavy, and specifically positioned nation like Albania or Montenegro (with a conscious acceptance of high LOLE risks balanced by imports or strategic interconnectors) is an economic noose around the neck for an industrial nation like Serbia.

Serbia must remain faithful to its own economic structure. As demonstrated in previous analyses, successful and secure systems do not operate on erratic market trends and passive administrative governance. Our command chain must be centralized, and the development of the energy mix strictly regulated through clear state quotas, technological priorities, and mandatory preliminary state verification for every new project. Only through an energy policy that is deeply sovereign and loyal to its own engineering physics can Serbia guarantee long-term national security and sustainable economic development.
