Though consumers have benefited from tolerable electricity tariffs over the last six months, courtesy of subsidies, the termination of indexation clauses in electricity bills has led to inflated nominal charges as tariffs incorporate the risk suppliers need to take when predicting the next month’s wholesale price levels ten days in advance.
New market rules introduced last August require suppliers to set and announce their electricity tariffs for each forthcoming month by the 20th of the preceding month.
The risk faced by suppliers through this new retail electricity market model has driven their nominal tariffs 20 percent higher, on average, compared to the previous system of floating tariffs with indexation clauses, triggered whenever wholesale prices exceeded certain limits.
Had the indexation clauses been maintained, power utility PPC, the dominant market player, would have recorded an average nominal retail price of 40.86 cents per KWh for the past six months, 28 percent below its average of 52.25 cents per KWh under the new system requiring the company to forecast wholesale price levels for each forthcoming month.
Market officials, including ESPEN, the Greek Energy Suppliers Association, had warned the new market model requiring wholesale electricity price forecasting would push up nominal retail prices, especially during times of market volatility, as is the case at present.
