Electricity (luz)
Supply is 230V and homes are billed on a contracted power level (potencia, in kW) plus consumption. To open or change a contract you need your NIE or passport, a Spanish bank account for direct debit (domiciliación), the property deeds or rental contract and the CUPS number printed on any previous bill. You can choose the regulated PVPC tariff or a fixed-rate contract from a free-market supplier such as Iberdrola, Endesa, Naturgy, TotalEnergies or Repsol. If the property has been empty a long while, an electrician's boletín may be required before reconnection.
