It also said it will have to reduce the power plant’s capacity to comply with environmental standards.
Romgaz took over Iernut thermal power plant in February 2013, in exchange for writing off debt owed by the power plant.
Following the move, Romgaz has become the second company in Romania to benefit from a government ordinance allowing natural gas and electricity producers to use own gas to generate energy.
Iernut, which has an installed capacity of 800 MW, covers around 5% of the local electricity market.
