Moldova’s energy system has been shaped by one central weakness: the country consumes far more energy than it can produce. With few domestic fossil fuel resources, limited traditional power generation and no nuclear plants, Moldova has long depended on imported natural gas, petroleum products and electricity. That dependence became a major economic and security risk after Russia’s invasion of Ukraine.
The country is now rebuilding its energy system around three ideas: stronger connections with Romania, a wider choice of European gas and electricity suppliers, and rapid growth in domestic renewable power. Moldova’s energy transition is therefore not only about reducing emissions. It is also about limiting political pressure, protecting consumers from supply interruptions and giving the country greater control over its economic future.
Why Energy Independence Has Become Moldova’s National Priority
Moldova normally imports around three-quarters of the energy resources it uses. It has no significant domestic production of natural gas or oil, while its electricity sector was historically tied to infrastructure located in the separatist Transnistrian region.
For many years, most of the electricity used on the government-controlled right bank of the Dniester came from the Moldavskaya GRES power station, usually called MGRES or the Cuciurgan power plant. The plant is located in Transnistria, outside the direct control of the Moldovan government, and is owned by the Russian company Inter RAO. It used Russian gas supplied through arrangements that were closely connected to the unresolved political status of the region.
This created an unusual energy system. Russian gas entered Moldova, much of it was sent to Transnistria, and MGRES used the fuel to produce electricity that was sold back to the rest of Moldova. At different times, the plant supplied between 60% and 80% of right-bank electricity demand.
That arrangement largely ended on January 1, 2025, when Gazprom stopped delivering gas to the Transnistrian region. Moldova also stopped purchasing electricity from MGRES for the right bank. Imports from Romania and other parts of the European market replaced much of that supply.
The change raised electricity costs and increased the importance of cross-border infrastructure, but it also removed one of Moldova’s deepest energy vulnerabilities. Energy policy is now closely tied to Moldova’s wider effort to join the European Union and separate its economy from Russian political influence.
Natural Gas in Moldova After the Gazprom Era
Natural gas remains important to Moldova even though the country has reduced its direct reliance on Gazprom. Gas is used in homes, industry, district heating systems and combined heat and power plants. In Chișinău and Bălți, gas-fired cogeneration facilities produce both electricity and heat, making natural gas especially important during the winter.
Moldova does not produce meaningful volumes of its own gas. It must buy the fuel from external suppliers, which leaves consumers exposed to regional market prices, currency movements and transport costs. The country also lacks large underground gas storage facilities of its own.
The main improvement has been supply diversification. The Iași–Ungheni pipeline connected Moldova with Romania in 2014, and its extension to Chișinău was completed in 2021. The pipeline allows gas bought on European markets to reach the country’s main centre of demand without depending on the traditional route through Transnistria.
Moldova can also use the Trans-Balkan pipeline in reverse. This system was originally built to carry Russian gas south through Ukraine and Moldova toward Romania, Bulgaria and Turkey. Technical changes now allow gas to move north from the Black Sea and Balkan region. Together, the Romanian connection and reverse-flow capacity give Moldova access to more suppliers and transport routes.
The state-owned company Energocom has taken a central role in buying gas from European markets and arranging security stocks. Because Moldova has no major domestic storage site, some reserve gas has been stored in facilities in Romania and Ukraine.
The remaining challenge is price. Diversified European gas is more secure than dependence on one Russian supplier, but it is not always cheap. Household support, heating subsidies and building efficiency programs will remain important parts of Moldova’s natural gas policy.
The Transnistria Energy Divide Has Not Disappeared
Ending right-bank purchases from MGRES did not remove the wider Transnistrian energy problem. The left bank still contains much of Moldova’s historical heavy industrial and electricity-generating capacity, including MGRES and the steel works at Rîbnița.
When Russian gas deliveries stopped in early 2025, homes and public buildings in Transnistria faced heating and gas cuts. Industrial production was also reduced. Gas deliveries later resumed through European market purchases financed under a separate and politically unclear arrangement.
The crisis showed that Moldova has two closely connected but differently governed energy systems. The constitutional authorities control energy policy on the right bank, while the Transnistrian administration controls major assets on the left bank. Pipelines and power lines cross the divide even when political institutions do not.
Moldova has introduced measures requiring gas reserves for essential consumers in Transnistria, but the long-term commercial model remains uncertain. Consumers in the region were accustomed to gas supplied under highly favourable conditions, while buying fuel at normal European market prices would place pressure on households and local industries.
Energy will therefore remain part of the wider Transnistrian settlement. The Moldovan government can reduce its own dependence on the region, but it cannot ignore the humanitarian, industrial and infrastructure problems created by a sudden collapse of the left bank’s energy system.
Electricity Infrastructure Is Moving Toward Romania
Moldova’s electricity network was built as part of the Soviet power system. Its strongest high-voltage routes traditionally ran east toward Ukraine and through the MGRES energy hub rather than directly west toward Romania.
A major change came in March 2022, when the Moldovan and Ukrainian electricity systems were synchronized with continental Europe through ENTSO-E. Synchronization allowed Moldova to buy electricity from Romania and other European markets, although physical transmission limits still restricted the volume that could be delivered.
The most important infrastructure project is the 400-kilovolt Vulcănești–Chișinău transmission line. The approximately 157-kilometre route connects southern Moldova with the capital and allows electricity arriving from Romania to move north without passing through the MGRES node in Transnistria.
Construction of the main line was completed in November 2025. Work continued into 2026 on the Vulcănești and Chișinău substations, protection equipment, testing and final energization. Once fully operational, the line is expected to carry enough electricity to cover more than half of Moldova’s peak demand under suitable operating conditions.
Further connections are planned. The Bălți–Suceava line would strengthen supply in northern Moldova, while a Strășeni–Gutinaș connection would create another route between central Moldova and the Romanian grid. Additional projects with both Romania and Ukraine are also under discussion.
These projects are more than standard grid upgrades. They are changing the direction of Moldova’s electricity system from an east-facing Soviet network into a west-facing European one.
Domestic Power Generation Still Has a Capacity Problem
Even with new transmission lines, Moldova needs more power generation within the territory controlled by the central government. Domestic plants usually cover only part of electricity consumption, with the remainder supplied through imports.
Termoelectrica operates the main combined heat and power facilities in Chișinău. CET-Nord performs a similar role in Bălți. These plants are valuable because they provide district heat as well as electricity, but they depend mainly on imported natural gas and are closely linked to winter heating demand.
The Costești hydropower station on the Prut River provides additional electricity, but its output is limited and can change with water conditions. Smaller renewable projects have expanded rapidly, although solar and wind cannot provide the same amount of power at every hour.
Moldova therefore needs a more flexible electricity system. Imports can balance local shortages, while gas-fired generation, batteries, demand management and stronger regional trading can respond when renewable output falls.
The development of competitive day-ahead, intraday and balancing markets is also important. Moldova has been aligning its market rules with the European system and working with Romanian market institutions. A functioning power market would allow suppliers to buy electricity more efficiently and make it easier for renewable producers to sell their output.
Renewable Energy in Moldova Is Growing Faster Than the Old Grid
Renewable energy has moved from a small part of Moldova’s electricity sector to one of its fastest-growing areas. Solar capacity has expanded through residential systems, commercial rooftops and utility-scale parks. Wind farms have also grown, especially in open agricultural areas with favourable wind conditions.
Moldova entered 2026 with close to 1,000 MW of installed renewable electricity capacity. This represents a major increase from the small solar and wind market that existed only a few years earlier. A 50 MW photovoltaic park at Rădeni in Strășeni District is among the projects showing the shift toward larger renewable installations.
Installed capacity does not equal continuous production. A solar plant generates little or no electricity at night, while wind production changes with weather conditions. Moldova can therefore have a large amount of renewable capacity and still depend on imports during cloudy, calm or high-demand periods.
The growth is already changing the electricity mix. Renewable sources supplied 16.7% of Moldova’s electricity consumption in 2024. During some periods in 2025, their share was considerably higher. In June 2025, renewable generation covered around 36% of electricity consumption, and during certain hours it was able to meet the country’s full demand.
Moldova has set a target of at least 30% renewable electricity consumption by 2030, together with a goal of 27% renewable energy in total final consumption. The country completed its first competitive wind and solar auction in 2025 and is preparing further rounds.
The next stage will be more difficult than simply installing panels and turbines. Moldova needs batteries, modern substations, better forecasting and stronger transmission capacity. Without these investments, renewable plants may sometimes produce more electricity than the local network can safely accept.
Biomass Connects Energy Policy With Rural Moldova
Solar and wind receive most of the attention, but biomass has long been one of Moldova’s most important domestic energy resources. Firewood, agricultural residues, pellets and other solid biofuels are widely used for heating, especially in villages and homes that are not connected to district heating or natural gas networks.
This reflects Moldova’s geography and economic structure. The country has a large agricultural sector, significant rural communities and cold winter periods. Crop residues, orchard waste and other biological material can provide local fuel, reducing the need for imported gas or heating oil.
Biomass also creates environmental and social problems. Traditional wood-burning stoves can be inefficient and contribute to indoor and outdoor air pollution. Heavy firewood demand can place pressure on forests if supply is not managed carefully. Modern pellet boilers, efficient stoves and properly controlled biomass heating systems offer better results than uncontrolled household burning.
Agriculture may also support more biogas production. Animal waste, food-processing waste and other organic material can be converted into electricity, heat or biomethane. Moldova currently uses biogas on a much smaller scale than solar or wind, but it fits the country’s agricultural economy and could provide more stable output than weather-dependent power sources.
Oil in Moldova Remains a Transport Security Issue
Moldova has no significant crude oil production and no major operating refinery. It relies almost completely on imported petroleum products, including diesel, gasoline, liquefied petroleum gas and aviation fuel.
Oil products accounted for about 39% of Moldova’s final energy consumption in 2023, making them the largest single source of energy used directly by consumers. Transport represented roughly three-quarters of final oil-product demand.
Road transport is the main reason. Cars, buses, trucks and agricultural machinery depend heavily on imported fuel. Diesel is especially important for freight, farming and commercial activity. Moldova’s rail system also remains largely dependent on fossil fuels rather than electric traction.
Petroleum supply is therefore an energy-security issue even though oil is not a major source of electricity. Disruption at regional refineries, border crossings or transport routes can quickly affect fuel availability and prices.
Moldova has also been slower than European rules require in creating formal emergency petroleum stocks. Authorities have worked on a system that would divide stockholding obligations between a central body and private importers. Building reliable reserves would help the country respond to temporary disruptions, but it requires financing, storage capacity and effective monitoring.
Electric vehicles could gradually reduce oil demand, particularly in Chișinău and other urban areas. However, Moldova’s vehicle fleet, household incomes and charging infrastructure mean that gasoline and diesel will remain important for many years.
Coal Has Only a Marginal Place in Moldova’s Energy Mix
Coal is not a major pillar of Moldova’s modern energy system. The country has no large commercial coal-mining industry, and coal contributes little to electricity production on the government-controlled right bank.
Small quantities of coal may still be used in industry or heating, but Moldova does not face the same coal-transition problem as countries with large mines and coal-fired power fleets. Its fossil fuel challenge is based mainly on imported natural gas and petroleum products.
Coal has occasionally appeared in emergency planning for Transnistria. MGRES was built with the ability to use more than one fuel, and operating part of the plant with coal was discussed when Russian gas supplies were interrupted. Such use would be an emergency response rather than a central part of Moldova’s national energy strategy.
The limited role of coal gives Moldova one advantage in its energy transition. It does not have a large coal workforce or mining region that must be economically replaced. However, this does not make decarbonization simple because the country remains highly dependent on other imported fossil fuels.
Moldova Has No Nuclear Power Plant
There are no nuclear reactors operating in Moldova, and the country does not have a large nuclear power program under construction. Its electricity system is relatively small, while the cost, technical requirements and regulatory structure needed for a conventional nuclear plant would be difficult to support.
Moldova still uses electricity generated by nuclear energy indirectly. Romania’s power system includes the Cernavodă nuclear station, and electricity purchased from the Romanian market may come from nuclear, hydro, gas, coal, wind or solar generation. Moldova also imports power through a regional system connected with other European nuclear-producing countries.
National energy planning documents have mentioned the possible long-term study of small nuclear technologies. Small modular reactors are sometimes presented as more suitable for smaller grids than traditional large reactors. At present, however, this remains a future option rather than an active Moldovan nuclear construction program.
For the coming decade, interconnection, renewables, storage, efficiency and flexible gas generation are much more important to Moldova than domestic nuclear power.
Energy Efficiency May Be Moldova’s Cheapest Energy Resource
Moldova’s energy debate often focuses on where gas or electricity will come from, but the condition of buildings is equally important. Many homes, schools, hospitals and public buildings lose large amounts of heat through poorly insulated walls, roofs, doors and windows.
This raises household bills and increases the volume of imported gas and electricity required during winter. It also makes price shocks more damaging for lower-income families.
Building renovation can reduce these risks. Insulation, modern windows, heating controls, efficient district heating networks and heat pumps can lower demand without reducing comfort. Heat pumps are particularly useful when they replace direct electric heaters, old gas boilers or inefficient solid-fuel systems.
District heating remains important in Chișinău and Bălți. Modernizing pipes and cogeneration plants can reduce losses and improve fuel efficiency. Smaller towns and rural areas may require different solutions, including heat pumps, efficient biomass systems and local renewable electricity.
Efficiency also supports energy independence. Every unit of energy saved is one less unit that Moldova must import, store, subsidize or transport through vulnerable infrastructure.
The Future of Moldova’s Energy System Runs West
Moldova’s energy transition is moving in a clear geographic and political direction. Romania is becoming the country’s main energy gateway, providing access to European gas markets, electricity exchanges and technical support. New transmission lines will strengthen that relationship and reduce the importance of routes controlled through Transnistria.
Domestic renewable energy will continue to grow, but solar panels and wind turbines alone cannot solve Moldova’s energy problems. The country also needs storage, flexible generation, modern power markets, efficient buildings and stronger emergency fuel reserves.
Natural gas and oil will remain important, especially for heating, transport and industry. The difference is that Moldova is trying to buy these fuels through competitive European markets rather than relying on a single politically dominant supplier.
The central question is no longer whether Moldova can return to its former energy system. It is whether the country can complete the infrastructure and market reforms needed to replace it. Its progress since 2022 shows that a small, import-dependent country can change its energy direction quickly when security, economics and national sovereignty all point toward the same goal.
