Moldova''s EU Integration and the Special Case of Transnistria

Transnistria''s Energy Dependence on Russia. The biggest challenge for Transnistria, as well as for Moldova, is the large fuel and energy dependence on Russia, mostly in the form of natural gas. For many years, gas has been supplied to Transnistria effectively for free, often in the form of a so-called "gas subsidy" (Roșa, 2021).

Why Putin Needs a Landing Force in Transnistria

The gas is conditionally free — the population of Transnistria pays for it, and the money goes to the budget of the unrecognized republic. Russia receives nothing for these supplies. Russian energy company Gazprom just keeps track of the supplies and records the debt to Moldova, which as of last September constituted $7 billion.

But over the last year, Moldova has managed to achieve full independence from Russian gas, develop alternative supply routes, unbundle the energy market, and disprove its debt to Russian majority state-owned gas company, Gazprom.

Transnistria: when buying time, make sure to use it wisely

According to Moldova''s minister of Energy, a deal on ensuring continued access by Gazprom to Moldova''s gas market after Ukraine''s decision to stop transit through its territory may be within reach. Rather than directly from Russia, gas would be imported through Turkey, Bulgaria and Romania, briefly go through Ukraine, and eventually reach Moldova, where it will likely be

6 FAQs about [Transnistria metro energy storage]

Should Transnistria buy electricity?

“The elites in Transnistria acknowledge already that we buy electricity from the region not because we have to but because the alternative is to throw the region into a humanitarian crisis,” Moldovan Energy Minister Victor Parlicov said in an interview. Still, officials are unequivocal: It’s time to end the multi-generational deadlock.

Why does Moldova import electricity from Transnistria?

Although Moldova currently once more imports 70-80 per cent of its electricity from Transnistria, it does so mainly because it is cheaper than electricity from Romania or Ukraine. But the synchronisation of its grid ensures access to alternative sources of supply, minimising the risk of energy blackmail from Russia.

Should Moldova buy Transnistria's gas?

In recent years, Brussels has given Moldova tens of millions of euros to build infrastructure and cement its connection to European energy networks, offsetting the costs of buying supplies from elsewhere. That means Moldova doesn’t have to buy Transnistria’s gas anymore, which could spell trouble for the breakaway state.

Should Transnistria end its energy monopoly?

Undercutting the breakaway region’s cash flow by ending its energy monopoly offers a chance to heal the country’s divisions and join the bloc as one nation. “Solving the energy issue with Transnistria would be a major step forward,” said Viola von Cramon-Taubadel, a German MEP and member of the European Parliament’s foreign affairs committee.

Why does Moldova rely on high-voltage cables in Transnistria?

Moldova also relies on high-voltage cables running through Transnistria, giving the region — and its Russian partners — even more leverage. “The beauty of it for the Russians was that by buying electricity from the Transnistrian region, we were basically financing the separatism in our own country,” Parlicov said. The EU has changed that calculus.

Should Transnistria be stopped?

Stopping payments to Transnistria would collapse the separatist state’s budget and leave hundreds of thousands of people there without incomes and basic services — a challenge that, for a country Moldova’s size, would be akin to the reunification of Germany following the fall of the Berlin Wall.
