Respuesta rápida
The 'alquiler de contador' is a regulated daily fee (~€0.026–€0.033/day) you pay the distributor for using their electricity meter in Spain. It appears on every bill, but watch for 'maintenance' or 'protection' add-ons bundled next to it — those are private, optional services, not regulated, and typically cost €5–€15/month.

The UK Retiree's 'Silent Vampire' on the Costa Blanca
A British retiree in a 75 m² flat near Alicante thought a creeping bill was just rising wholesale prices. A forensic audit of his PDF revealed a €5.45/month 'Premium Protection' line item bundled right next to his regulated meter rental. He hadn’t noticed because it looked official, but over three years it had quietly added more than €195 he never asked for.
