Calota added that believing that RADET would become efficient in the current structure is an illusion.
Bucharest mayor Sorin Oprescu has previosuly said that the merger of the two companies, scheduled for March, will solve the thermal power issues in Bucharest.
Heating distributor RADET is subordinated to Bucharest City hall, while Electrocentrale Bucuresti (ELCEN) is owned by the Economy Ministry.
ELCEN is the biggest thermal power producer in Romania (40%) and Bucharest (90%) and one of the major electric power suppliers in the country (4.8%). RADET is the biggest debtor of ELCEN.
