Hungary's capacity for hydroelectricity was 57 MWs in 2015, and the country's two largest hydroelectric dams, Tiszalök and Kisköre, are built on the River Tisza. However, due to unsuitable geographical conditions and civil resentment, hydroelectricity is not prevalent in Hungary. The country's greatest hydroelectric project was the Gabčíkovo–Nagymaros Dams, which was built together with Slovakia during the Communist era. However, the project became widely hated in Hungary due to environmental concerns and is now a source of dispute between the two countries.

The Gabčíkovo–Nagymaros Dams: Hungary's greatest hydroelectric project
Hydroelectricity is not common in Hungary due to geographical limitations and civil resentment. The country's hydroelectric capacity was just 57 MWs in 2015. Despite this, Hungary has embarked on several hydroelectric projects, the most notable being the Gabčíkovo–Nagymaros Dams.
The Gabčíkovo–Nagymaros Dams were intended to address several issues, including regular flooding, the need for a clean source of electricity, and the improvement of inland navigation on the Danube River. The plan involved diverting part of the Danube River into an artificial canal at the Hungarian village of Dunakiliti to a hydroelectric power plant near Gabčíkovo, which would have eight turbines with a capacity of 720 MW.
However, the project faced strong opposition from biologists and the general public. Biologists were concerned that the construction of the dams would damage the treasured scenery of the Danube Bend and the underground water reserves that over a million Hungarians rely on, especially in the Budapest region. As a result of an intensive campaign, the project became widely unpopular in Hungary, seen as a symbol of the old regime.
Despite the opposition, construction of the Gabčíkovo dam continued in Slovakia, and it now produces 2600 GWh of electricity annually, making it Slovakia's largest hydroelectric plant, supplying around 8% of the country's electricity consumption. The non-existence of the Nagymaros dam has created obstacles for inland navigation on the Danube due to low water levels. Hungary has requested that Slovakia manage regulation works on the problematic stretch of the Danube that was supposed to be addressed by the Nagymaros backwater.

The Tisza Dam
Hydroelectricity is not prevalent in Hungary due to unsuitable geographical conditions and civil resentment. The country's capacity for hydroelectricity was 57 MWs in 2015. Hungary's greatest hydroelectric project was the Gabčíkovo–Nagymaros Dams, which was built to eliminate regular flooding, provide a clean source of electric power, and allow year-long navigability of the river. However, the project was widely opposed due to environmental concerns and the potential damage to the treasured scenery of the Danube Bend and the underground water reserves. As a result, no major hydroelectric projects are currently supported by the Hungarian government.
One of the hydroelectric dams in Hungary is the Tisza Dam, also known as the Kisköre Dam. It is a gravity dam located on the Tisza River near Kisköre in Heves County, Hungary. The Tisza River is one of the major rivers of Central and Eastern Europe and was once known as "the most Hungarian river" as it flowed entirely within the Kingdom of Hungary. Today, it crosses several national borders, including Ukraine, Romania, Hungary, Slovakia, and Serbia.
The Tisza River is part of the Danube River catchment area and is the longest tributary of the Danube, with a length of 966 kilometers. It contributes about 13% of the Danube's total runoff and drains an area of approximately 156,087 square kilometers. The Tisza River Basin, covering an area of 157,186 square kilometers, is the largest sub-basin of the Danube River Basin.
The Tisza River is of significant importance to the countries it traverses, and international cooperation has been established to ensure integrated water resources management. The ICPDR (International Commission for the Protection of the Danube River) plays a crucial role in coordinating and implementing the River Basin Management Plan for the Tisza River Basin, with the long-term goal of improving water status and flood risk prevention.

The Danube: a river of woe between Slovakia and Hungary
The Danube is the second-longest river in Europe, flowing through Central and Southeastern Europe and connecting ten countries, including Germany, Austria, Slovakia, Hungary, Croatia, Serbia, and Romania. With its majestic beauty and historical significance, it has inspired music and played a vital role in the settlement and economic growth of the region. However, the Danube has also been a source of conflict and environmental disputes, particularly between Slovakia and Hungary.
The river serves as a natural border between the two countries, and its management has been a point of contention. The Gabčíkovo–Nagymaros Dams project, intended to provide flood control, hydroelectric power, and improved navigation, became a symbol of discord. While Slovakia completed the Gabčíkovo Hydroelectric Power Station, Hungary halted construction on its side due to environmental concerns and civil resentment. This dispute led to legal proceedings and highlighted the differing priorities and challenges faced by the two nations.
The Danube's course through Slovakia and Hungary has significant geographical variations. In Slovakia, the river flows through the Slovakian Lowlands, while in Hungary, it enters the Little Alfold plain, where it slows down and deposits large amounts of sediment, forming islands and affecting navigability. The river then passes through the Visegrád Gorge, with steep banks adorned by Hungarian fortresses, castles, and cathedrals. These contrasting landscapes impact the river's behaviour and present unique challenges for its management.
The environmental consequences of damming the Danube have been a significant concern. Biologists worried that the Gabčíkovo–Nagymaros Dams would harm the treasured scenery of the Danube Bend and underground water reserves that over a million Hungarians rely on. Studies have shown mixed results, with some areas experiencing improved groundwater levels and quality, while others face challenges due to low water levels and the non-existence of the Nagymaros dam impeding inland navigation.
The Danube River Protection Convention, established by the International Commission for the Protection of the Danube River (ICPDR), aims to address these complexities. The commission includes both Slovakia and Hungary and seeks to promote sustainable and equitable water management, balancing the diverse needs and impacts along the river. While the Danube has been a source of conflict, it is also an opportunity for collaboration and the development of equitable solutions that respect the river's environmental and cultural significance.

The Rhine-Main-Danube Canal system of inland navigation
The Rhine-Main-Danube Canal, also known as the Main-Danube Canal, RMD Canal, or Europa Canal, is a navigable waterway in Bavaria, Germany. It connects the Main and Danube rivers, providing a route between the Rhine delta in the Netherlands and the Danube Delta in south-eastern Romania and southwestern Ukraine. The canal is 171 kilometres long and was completed in 1992, creating a 3,500-kilometre waterway that passes through 15 countries. The canal has 16 locks, each about 190 metres long, 12 metres wide, and 30 metres deep. It rises to a height of over 406 metres above the Swabian Alps, south of Nuremberg.
The idea of a canal linking the Danube and Rhine basins dates back to 793 when Charlemagne ordered the construction of the Fossa Carolina, also known as the Karlsgraben, connecting two rivers in Bavaria. The modern canal project faced several challenges, including competition from railways and environmental concerns. The canal carries cargo traffic that would otherwise require 250,000 truck trips or 3,000 freight trains annually. It has also facilitated the spread of various species of invertebrates and fish between the Danube, Main, and Rhine rivers.
The Rhine-Main-Danube Canal system includes the controversial Gabčíkovo–Nagymaros Dams, which were intended to prevent flooding, provide a clean source of electricity, and enable year-long navigability of the river. The project faced opposition due to concerns about its environmental impact and became a symbol of the old regime in Hungary. The dam's non-existence has caused obstacles to inland navigation on the Danube Pan-European corridor due to low water levels.
Hungary has not pursued major hydroelectric projects due to unsuitable geographical conditions and civil resentment. The country's capacity for hydroelectricity was 57 MWs in 2015, with the Gabčíkovo–Nagymaros Dams complex being its greatest hydroelectric project. The Gabčíkovo Hydroelectric Power Station in Slovakia, part of the original plan, produces 2600 GWh of electricity annually, supplying around 8% of the country's electricity consumption.

Hungary's two largest hydroelectric dams: Tiszalök and Kisköre
Hungary's capacity for hydroelectricity was 57 MWs in 2015, and its greatest hydroelectric project was the Gabčíkovo–Nagymaros Dams. However, due to environmental concerns and civil resentment, no major hydroelectric projects are supported by the Hungarian government.
The Gabčíkovo–Nagymaros Dams complex was built in conjunction with Slovakia, which continued construction despite Hungary's withdrawal from the project due to civil resentment and environmental concerns. The dam was intended to prevent flooding, provide a clean source of electricity, and enable year-long navigation of the river as part of the Rhine-Main-Danube Canal system.
Tiszalök and Kisköre are two of Hungary's largest hydroelectric dams. The Tiszalök dam is located on the Tisza River, a tributary of the Danube River, and has a capacity of 24 MW. The dam was completed in 1970, with two turbines and a length of 390 meters. The Kisköre dam, also situated on the Tisza River, was finished in 1975 and has a capacity of 48 MW. With a length of 550 meters, the Kisköre dam features three turbines.
The Tiszalök and Kisköre dams are important sources of renewable energy for Hungary, contributing to the country's energy mix and helping to reduce reliance on fossil fuels. While Hungary may not have the most favourable geographical conditions for hydroelectricity, these dams showcase the country's commitment to exploring diverse energy sources.
