How to change potencia

Spanish utility companies rarely respond to customer emails. You have 3 real options:

  • Call your customer line — expect 15-30 min wait and automated menus.
  • Online — log into your "Área de clientes" (most companies allow changes there).
  • Punt de servei — fewer each year, but still possible.

Decreasing power does not require an electrician or CIE — yet most people don't know this.
