Independent Greeks have thrown their weight behind SYRIZA's proposal for a referendum on privatizing part of Public Power Corporation (PPC).
In a statement Thursday, the country's right-wing anti-bailout party said leader Panos Kammenos had called leftist opposition leader Alexis Tsipras to declare his support for the move.
The proposal for a plebiscite would need the support of at least 120 of 300 MPs before it could be put before Parliament. Then, it would need the votes of at least 180 MPs for a popular vote to be held.
Greece faced nationwide power cuts on Thursday as a rolling strike began against government plans to break up the country's main electricity provider.
State power distribution operator DEDDIE said one-hour cuts would be imposed from midday in various parts of the mainland as 13 production plants of the Public Power Corporation went offline.
PPC unionists have announced rolling 48-hour strikes against plans to break up the company by 2015 under privatization efforts linked to the country's economic rescue.
