1. Introduction Hydropower has long been a significant part of the energy landscape in the Balkans. With its abundant water resources, the region has the potential to harness hydroelectric power for sustainable energy production. However, the development and operation of hydropower in the Balkans are influenced by a complex interplay of factors, including geographical, environmental, economic, and political aspects. This article aims to provide a comprehensive overview of the current situation of hydropower in the Balkans, its prospects for the future, and the constraints that may impede its further development. 2. Current Situation of Hydropower in the Balkans 2.1 Existing Hydropower Installations The Balkans already have a considerable number of operational hydropower plants. As of [latest available data], a significant amount of hydropower capacity has been installed across the region. For example, countries like Albania rely almost entirely on hydropower for their electricity generation. In fact, hydropower contributes nearly 100% to Albania’s electricity supply, highlighting its crucial role in the country’s energy mix. Other countries in the Balkans, such as Bosnia and Herzegovina, Croatia, Montenegro, Serbia, and North Macedonia, also have a substantial share of hydropower in their energy production. In Bosnia and Herzegovina, hydropower accounts for approximately one – third of the total electricity generation, while in Montenegro, it is around 50%, in Serbia about 28%, and in North Macedonia nearly 25%. These hydropower plants vary in size and capacity. There are large – scale hydropower projects that have been in operation for decades, often built during the socialist era in the former Yugoslavia. These plants have relatively high installed capacities and play a major role in meeting the base – load electricity demand. Additionally, in recent years, there has been an increase in the number of small – scale hydropower plants (SHPs), especially those with an installed capacity of less than 10 megawatts (MW). In fact, as of [data year], 92% of the planned hydropower projects in the Balkans were small – scale, although many of these planned small – scale projects are yet to be realized. 2.2 Hydropower Projects Under Construction Despite the existing hydropower infrastructure, there are still numerous hydropower projects currently under construction in the Balkans. As of [recent data], around [X] hydropower projects are in the construction phase. These ongoing projects are aimed at further increasing the hydropower capacity in the region. For instance, in Albania, several new hydropower projects are being built to enhance the country’s energy self – sufficiency and potentially export surplus electricity. However, the construction of these projects is not without challenges. Some of the projects face delays due to various factors such as complex permitting processes, environmental concerns raised by local communities and environmental organizations, and financial constraints. For example, in some cases, project developers struggle to secure sufficient financing for the construction of large – scale hydropower plants, especially in the current economic climate where access to capital can be difficult. 2.3 Hydropower Projects in Protected Areas A concerning aspect of hydropower development in the Balkans is the high number of projects planned or under construction within protected areas. Approximately 50% of all hydropower projects (both planned and under construction) are located within existing or planned protected areas. This includes areas such as national parks and Natura 2000 sites. For example, in Bosnia and Herzegovina, the Neretva River, which flows through protected areas, is threatened by a large number of small – and large – scale hydropower projects. These projects pose a significant risk to the unique ecosystems and biodiversity that these protected areas are meant to safeguard. The presence of hydropower projects in protected areas has led to intense debates between proponents of energy development and environmental conservationists. While hydropower is considered a renewable energy source, the construction and operation of dams and power plants in sensitive ecological areas can have negative impacts on river ecosystems, fish populations, and wildlife habitats. 3. Prospects for Hydropower in the Balkans 3.1 Energy Transition and Climate Goals The global push for energy transition and the need to meet climate goals present significant opportunities for hydropower in the Balkans. As countries in the region strive to reduce their greenhouse gas emissions and shift towards renewable energy sources, hydropower can play a crucial role. Hydropower is a renewable and relatively low – carbon energy source compared to fossil fuels. By increasing the share of hydropower in the energy mix, Balkan countries can contribute to their national and international climate commitments. For example, the European Union’s Green Deal initiatives encourage member states and neighboring countries to accelerate the transition to a low – carbon economy. The Balkans, as a region adjacent to the EU, can align its energy policies with these goals and attract investment in hydropower development. This can also lead to the modernization of existing hydropower plants, improving their efficiency and environmental performance. 3.2 Technological Advancements Advancements in hydropower technology offer promising prospects for the Balkans. New technologies are being developed to improve the efficiency of hydropower plants, reduce their environmental impact, and enable the development of smaller – scale and more decentralized hydropower projects. For instance, the development of fish – friendly turbine designs can help mitigate the negative impacts of hydropower plants on fish populations, allowing for a more sustainable form of hydropower development. In addition, pumped – storage hydropower technology has the potential to play a crucial role in the Balkans. Pumped – storage plants can store energy during periods of low electricity demand (by pumping water from a lower reservoir to a higher one) and release it during peak demand. This can help balance the intermittent nature of other renewable energy sources such as solar and wind power, which are also being increasingly developed in the region. With the expected growth in solar and wind power installations in the Balkans, pumped – storage hydropower can enhance the stability and reliability of the electricity grid. 3.3 Regional Energy Market Integration The integration of the Balkan energy markets into the broader European energy market presents opportunities for hydropower development. As the region’s energy markets become more interconnected, there is a greater potential for the export of hydropower – generated electricity. For example, during periods of high water availability and excess hydropower generation, Balkan countries can export electricity to neighboring countries, thereby increasing their revenue and contributing to regional energy security. Furthermore, regional energy market integration can lead to the sharing of best practices in hydropower development, operation, and management. It can also attract foreign investment in hydropower projects, as international investors see the potential for returns in a more integrated and stable energy market. 4. Constraints to Hydropower Development in the Balkans 4.1 Climate Change Climate change is a significant constraint to hydropower development in the Balkans. The region is already experiencing the impacts of climate change, including more frequent and severe droughts, changes in precipitation patterns, and rising temperatures. These changes directly affect the availability of water resources, which are essential for hydropower generation. In recent years, countries like Albania, North Macedonia, and Serbia have faced severe droughts that have led to reduced water levels in rivers and reservoirs, forcing hydropower plants to reduce their electricity generation. As climate change progresses, these drought conditions are expected to become more frequent and intense, posing a serious threat to the long – term viability of hydropower projects in the region. Additionally, changes in precipitation patterns can lead to more erratic river flows, making it difficult to plan and operate hydropower plants efficiently. 4.2 Environmental Concerns The environmental impacts of hydropower development have become a major concern in the Balkans. The construction of dams and power plants can cause significant damage to river ecosystems. Dams can disrupt the natural flow of rivers, alter sediment transport, and isolate fish populations, leading to a decline in biodiversity. In addition, the flooding of large areas of land to create reservoirs can destroy habitats for wildlife and displace local communities. The high number of hydropower projects in protected areas has drawn particular criticism from environmental organizations. These projects are often seen as a violation of the conservation objectives of protected areas. As a result, there has been increased public opposition to hydropower projects in some parts of the Balkans, which can lead to delays or even cancellation of projects. For example, in Albania, the proposed hydropower projects in the Vjosa River, which was earmarked to become Europe’s first wild river national park, faced significant opposition from environmentalists and local communities. 4.3 Financial and Technical Constraints Hydropower development requires significant financial investment, which can be a major constraint in the Balkans. The construction of large – scale hydropower plants, in particular, involves high upfront costs for infrastructure development, equipment purchase, and project planning. Many Balkan countries, which may already be facing economic challenges, struggle to secure the necessary financing for such large – scale projects. In addition, there are technical challenges associated with hydropower development. The aging infrastructure of some existing hydropower plants in the Balkans requires significant investment for modernization and upgrade to improve efficiency and meet current environmental and safety standards. However, the lack of technical expertise and resources in some countries can impede these efforts. Furthermore, the development of new hydropower projects, especially those in remote or mountainous areas, may face technical difficulties in terms of construction, operation, and maintenance. 5. Conclusion Hydropower currently holds a significant position in the energy landscape of the Balkans, with a substantial existing capacity and ongoing construction projects. However, the future of hydropower in the region is a complex interplay of promising prospects and formidable constraints. The drive towards energy transition and climate goals, along with technological advancements and regional energy market integration, offers opportunities for further development and modernization of hydropower. Nevertheless, climate change, environmental concerns, and financial and technical constraints pose serious challenges. To overcome these challenges, Balkan countries need to adopt a more sustainable and integrated approach to hydropower development. This includes investing in climate – resilient hydropower infrastructure, addressing environmental impacts through better planning and technology, and finding innovative financial solutions. By doing so, the Balkans can maximize the potential of hydropower as a clean and renewable energy source while minimizing its negative impacts on the environment and society.
