More than 51,000 households were left without gas and 1,500 apartment buildings had no winter heat in Moldova's Moscow-backed separatist enclave, authorities said on Monday, as Moldova and Russia traded blame for an escalating energy crisis.

"Russian propaganda tries to create a story in which Moldova becomes a ‘problematic actor,’ although the government has proposed clear solutions to avoid the crisis," Moldovan government spokesperson Daniel Voda said on Jan.

The head of Moldova’s breakaway region Transnistria has urged residents to burn firewood for heating and warned that blackouts cannot be avoided, after Moscow stopped supplying gas via Ukraine.

The move was connected with, but not required by, the expiration at the end of 2024 of Russia’s contract with Ukraine for transit of natural gas to Europe. The looming energy crisis is likely to have a strong negative effect on Moldova’s ruling pro-European Party of Action and Solidarity (PAS) in parliamentary elections due in the second half of 2025.

Russian energy giant Gazprom said on Saturday it would suspend gas exports to Moldova from 0500 GMT on Jan. 1 due to unpaid debt by Moldova, which is bracing for severe power cuts.

Moldova has accused Russia of triggering an energy crisis after tens of thousands of homes in its eastern breakaway region of Transnistria were left without heating, gas or electricity following the end of a Ukraine gas transit agreement last week.
