How the Portuguese price is set
Portugal shares the Iberian market with Spain. Most of the time both countries have the same price; when the interconnector is full, the prices split.
Indexed retail offers pass this wholesale price on, plus the ERSE grid access tariff, the special consumption tax (IEC), the supplier's losses and margin, and VAT.
Our final price uses the 2026 access tariffs for normal low voltage up to 20.7 kVA – single rate (€0.0607 per kWh) or two-rate with off-peak from 22:00 to 08:00 (€0.0158 off-peak, €0.0835 otherwise) – plus €0.001 IEC, a sample €0.02 for losses and margin, and 23% VAT, the rate that applies to consumption above the reduced-VAT allowance. Fixed monthly charges are not included.
