Electricity consumers resorting to the universal supply service, covering the energy needs of households and small businesses shunned by suppliers for failing to be punctual with payments, will face tariff levels 12 percent over the regular market rate, according to a related ministerial decision.

The country’s five biggest electricity suppliers, in terms of retail market share, will need to share the pool of old and new unwanted customers and provide the universal supply service.

Previously, the market leader – consistently PPC – was forced to offer the service alone after suppliers chose not to submit bids to related universal service tenders.

Under the service’s new rules, the highest tariff rate among the top five suppliers will serve as the base for the 12 percent overcharge.

PPC, still dominating Greece’s retail electricity market with a 90 percent share of power meters, Protergia (Mytilineos), Heron, Elpedison – all three control 3 percent each – and NRG (1%) are the top five suppliers who, by law, must offer the universal supply service.
