The energy ministry stated that household electricity prices fell by nine percent year on year, that the decline was the largest among comparable economies, and that the subsidy programme was the principal cause.
“Average household tariff fell 9.1% against the same quarter one year earlier.”
“Of the twelve economies in the panel, none recorded a steeper single-year decline.”
“Wholesale price movement accounts for most of the fall; the subsidy contributes an estimated third.”
