Greece’s retail electricity market is operating with nearly €3 billion in overdue customer debt, a burden that regulators say raises credit risks for suppliers and indirectly increases costs for consumers who pay their bills on time.
According to the annual report of the Regulatory Authority for Waste, Energy and Water (RAAEY), overdue obligations owed by households and businesses to electricity suppliers totaled about €2.98 billion in 2025, down 22% from €3.4 billion in 2024.
Low-voltage customers, including households and small businesses, accounted for the largest share of the debt, at roughly €2.1 billion, or about 80% of total arrears. Medium-voltage customers owed €683.79 million, while high-voltage customers owed €214.3 million.
Household debt totaled €710 million. Commercial, industrial and other small businesses accounted for the largest category, with about €819 million in overdue obligations. Businesses connected to medium voltage owed €577 million, while large companies connected to high voltage owed €55 million.
“The total amount of debt, which approaches €3 billion, demonstrates the scale of the phenomenon and its significance for the sustainability of suppliers, the management of credit risk and, ultimately, the overall functioning of the retail market,” RAAEY said in its report.
