On 31 January 2026 a disturbance in Ukraine’s electricity grid drove a voltage collapse in neighbouring Moldova, leaving large parts of the country without power. The lights came back on later the same day, but the incident served as a reminder that Moldova’s energy system rests on fragile foundations.
Russia has long weaponised energy to interfere in Moldovan politics, leveraging Soviet-era grids, gas supplies and business relationships. In November 2024 we documented how leadership in Chișinău, Moldova’s capital, was beginning to assert itself and push back. Since then, Moldova has managed to significantly reduce Moscow’s energy hold, but its system still runs on thin infrastructure and limited redundancy in a region under wartime strain.
Now the next big challenge lies with Europe. Can the Energy Union turn geopolitical alignment into reliable, affordable electricity by financing and building the networks that make integration real?
Dismantling Dependence: Moldova Escapes Russia’s Energy Trap
Moldova has faced repeated energy disruptions in recent years, and January 2025 brought another. Russia had been in dispute with European leaders over the long-anticipated expiry of a gas-transit deal. Hoping to force a change of direction from Ukraine and put pressure on Moldova’s pro-Europe leaders, Russia broke its contractual obligations and ended gas deliveries to Transnistria (a breakaway region internationally recognised as part of Moldova but which retains de facto independence with Russian support). This forced the region’s thermal power station – which had previously supplied more than 70 per cent of Moldova’s electricity – to switch into emergency coal-fired mode and end supply to areas under Chișinău’s control. Electricity prices surged.
Within days, Brussels mobilised a €30 million emergency-assistance package, supplemented by new supply contracts with Romania, to stabilise Moldova’s grid. Meanwhile Transnistria’s de facto authorities rejected European Union help. Residents suffered power outages that affected heating and running water, and closed schools and hospitals, while thousands of industrial workers were laid off.
Transnistria had enjoyed a comfortable income from selling electricity without paying Russia for the gas feedstock. Without that revenue, and unwilling to accept EU aid, it turned to Moscow for help, which finally arrived in the form of a small loan to buy gas in Europe via a Hungarian intermediary.
As a condition of allowing the gas to transit its territory, Chișinău secured concessions that included broadcasting Moldovan state TV in the separatist region, the release of some political prisoners and the removal of several illegal security checkpoints. The emergency loan and transit agreement helped to cover household consumption in Transnistria, but was insufficient to restore electricity exports and Transnistria’s ailing industrial sector. As a result, the region suffered further economic setbacks as the year continued.
In areas under Chișinău’s control, a further two-year €250 million EU-assistance package helped recapitalise the ailing system operator, accelerate grid upgrades and compensate households for increased energy costs. On 1 September, the government relieved Moldovagaz of its role as the national gas supplier, pushing Russia’s state-backed energy giant Gazprom (which, with Transnistria, had a controlling stake in Moldovagaz) out of the market.
In September’s parliamentary elections, Moscow-aligned opposition parties offered a return to cheap energy through renewed friendship with Russia. These efforts failed at the ballot box and President Maia Sandu’s government secured a further four-year mandate. By the end of 2025, Moscow’s political ambitions had been frustrated, the separatist authorities in Transnistria faced growing economic constraints and Russia’s last real foothold in Moldova’s energy market was gone.
Fragility: Moldova’s Energy System Today
In many ways Moldova’s transition is impressive, but it rests on unstable foundations: domestic thermal generators that cover 15 to 20 per cent of peak demand, a large but under-utilised renewable-energy capacity, and imports from Romania and Ukraine.
In 2025 Moldova’s state-owned electricity wholesaler Energocom imported 90 per cent of its contracted supply. These imports are still routed through a single high-voltage line that terminates in Transnistria.
On 31 January 2026, a combination of severe cold weather and knock-on effects of war damage to Ukraine’s energy infrastructure caused that one high-voltage line to lose capacity, triggering load shedding across the network. However, in sharp contrast to earlier incidents, normal service was restored in only hours. This reflected emergency preparations made over the past year, including creating “energy islands” (parts of the grid that could be supplied via lower-voltage connectors with Romania), providing backup generators for critical services, and developing detailed plans to re-route and restore voltage across the network.
Further help is on the way. An alternative high-voltage interconnector is due to be completed in May 2026, with two more expected by the end of 2027 and 2029 respectively. This will provide much-needed redundancy, with total transit capacity equal to almost double Moldova’s peak demand.
To facilitate imports, in November 2025 Moldova completed the transposition of the Energy Community’s Electricity Integration Package, formally aligning national energy laws with the EU’s internal electricity-market rules. The government has enabled day-ahead trading and an intraday market, substantially improving the ability of both market participants and the system operator to proactively manage demand and pricing.
Moldova has also made impressive strides on renewable energy, with almost 1GW of installed capacity. Over 500MW of new renewables capacity was added in 2025 alone, with more than 200 suppliers now selling directly into the grid. At its peak on a single day in June, renewable energy provided 48 per cent of demand. Like many other countries, however, Moldova struggles to utilise this capacity when and where it is needed, because grids, flexibility and market participation are lagging.
Moldova’s gas supply, important for heating in cold winters, is also more diversified. The country has 21 international suppliers, including a multi-year agreement linked to Romania’s Neptun Deep offshore facility. New storage facilities and advanced-purchase requirements are further buffering Moldova against price shocks, while efficiency and electrification efforts continue.
Moldova has escaped the immediate threat of coercive energy disruption. But the bigger question remains: how can a small, import-dependent economy build an energy system that is not only independent but economically sustainable?
The EU’s Unfinished Energy Union: A Chance to Shine?
Becoming part of an integrated European electricity grid should mark a turning point for countries such as Moldova. The combined strength of European capital, technology and institutions should be more than enough to accommodate a smaller economy like Moldova seeking to contribute to the green transition. Unfortunately, it is not that simple.
European cooperation on energy has evolved slowly and unevenly. Past energy crises and the Energy Union framework highlighted the case for deeper integration, but political will has been insufficient. Energy remains a shared EU competence: while the EU can set targets and provide guidance, member states ultimately decide on investment and energy mixes. What exists today resembles a confederation of national markets that interact in beneficial but limited ways.
Europe has the world’s largest interconnected grid, leading grid companies and fast-growing renewables, but infrastructure modernisation and cross-border interconnections have been neglected. The April 2025 blackout in Spain and Portugal, triggered by a voltage-control failure cascading across borders, could likely have been avoided with upgraded grids and stronger interconnection capacity between France and Spain.
After years of piecemeal reform and underinvestment, the EU has finally realised that affordable, stable and independent energy is crucial for its competitiveness. The idea of a connected Europe has always been present, but its scope has now expanded to include Europe as a whole, from the United Kingdom to Moldova and Ukraine.
This recognition is beginning to translate into policy. The EU’s Action Plan for Affordable Energy, together with the European Grids Package, signals a more serious attempt to tackle the structural causes of high prices and fragmentation by treating energy networks as shared European infrastructure rather than a loose aggregation of national systems. The accompanying Energy Highways initiative pushes this logic beyond the EU’s borders, identifying priority corridors needed to make a connected European market work in practice. In simple terms, these are key cross-border links meant to move electricity at scale where national planning has fallen short. Moldova’s inclusion reflects a growing acknowledgement that affordability and security now depend on integrating neighbouring systems into a continental energy space.
Affordability and Resilience: The Road Ahead
Europe does not want to subsidise Moldova’s energy costs forever. Strategic independence has come with a price tag that citizens will feel directly. In June 2025, Moldovan households paid 12 per cent more for electricity than those in Romania, 66 per cent more than Bulgaria and 185 per cent more than Georgia. In a country where the median salary is roughly a quarter of the EU average, these differentials matter enormously.
Eurosceptics and Kremlin sympathisers will point to these figures as proof that EU integration punishes ordinary people. In fact, Moldova’s costs stem from decades of grid degradation, an investment backlog and Russian coercion. But acknowledging that Russia’s cheap gas was a trap does not make Moldovans’ bills more affordable. The country faces challenges that others, including Ukraine, are likely to confront.
The most pressing of these include:
Baseload capacity: Moldova does not have enough domestic baseload generation capacity to support domestic demand. The natural gas plant, controlled by separatists in Transnistria, may not be worth upgrading even if it can be relied upon under a future settlement, and the capital cost for a new gas or nuclear facility could be prohibitive.
Import dependency: Imports from Romania are reliable as long as a friendly government sits in Bucharest, but they are not cheap. Ukraine might play a bigger role in the future but with ongoing Russian attacks on energy systems and peace talks dragging on, it remains an unknown factor.
Renewables optimisation: Moldova could theoretically do more with its renewables. For example, it could develop large-scale energy-storage systems, add gas turbines to balance the peak load and expand smart metering, coupled with dynamic consumer-pricing systems, to encourage consumers to use electricity when it is most available. Moldova could even explore selling surplus energy to Romania for profit. This would, however, require yet more grid infrastructure and a stable economic bargain between the two administrations providing predictable returns to traders on both sides.
Transnistria: The region remains unwilling to accept EU help and relies on dwindling levels of financial support from Moscow. Its industrial backbone was built on cheap and abundant gas from Russia, which is no longer available. Modernisation could be expensive (or even unfeasible), but the social and political cost of closures would be high, too. This adds a major potential liability to Moldova’s balance sheet in the event of a future settlement or a spontaneous collapse. Economic growth in the rest of Moldova could help absorb spare labour from this region, partially offsetting this risk.
Moldova as a Testbed for Energy Innovation
Many of the issues outlined earlier relate to capital, markets and technology – areas in which the private sector has a significant role to play. Within Moldova’s new government there are leaders with private-sector investment expertise who understand this and are eager to leverage private-sector partnerships to create a more flexible and responsive system.
The introduction of a new Energy Sandbox, providing regulatory flexibility for private operators wanting to test new solutions, such as energy communities, balancing services, tariff policies and smart grids, is among the positive developments.
The first project has already started – a pilot of “vehicle-to-grid” technologies that uses electric cars as dynamic storage to help support peak electricity demand. This is not a magic bullet but, when used in combination with other storage and demand-management systems, might help Moldova to deploy its generating capacity more efficiently.
Moldova is pursuing multiple solutions that address real constraints – curtailment (when renewable output has to be wasted), imbalance (mismatches between supply and demand) and grid congestion. The country offers a low-cost, low-risk environment in which to test and iterate solutions, with a market and regulatory framework that can still be proactively shaped and a government that is a constructive partner.
Grid-flexibility providers, storage and hybrid renewables developers, demand-response and pricing specialists, and infrastructure investors with operational capability would be well suited to this opportunity. Solutions that show promise could not only access EU financing already allocated to Moldova’s energy transition, but also bigger markets such as Ukraine, which will likely need similar solutions in the years to come.
From Reform to Regional Integration?
Moldova still offers lessons – but different ones to those of 2024. It has demonstrated political resolve in the face of the Kremlin’s energy pressure and, with assistance from Brussels and Washington, dealt with upfront geopolitical risks.
It now needs to shape a system that is economically viable, based on a strategy that goes beyond the war in Ukraine and EU integration. Ideally, this would be as part of a bigger regional energy market in which Moldova could play a complementary role. This kind of future depends heavily on the will of EU and member-state lawmakers to embrace a common energy market backed by investment plans, more pooled capital, open markets, new technology and greater private-sector participation.
The same forces needed to restore German and French industrial competitiveness could also help improve prospects for countries on Europe’s periphery, bringing wider benefits for stability and growth.
As the single energy market continues to take shape, Moldova’s sandbox offers an opportunity for private investors to innovate and demonstrate the value of novel energy systems.
