About us

What does residential electrification involve, and why has it become one of the major energy transformations? We review the main key aspects of a change that is revolutionising the way energy is consumed and managed in the home.

Portugal has become a key country for Iberdrola thanks to its commitment to renewable energy, energy storage through pumped-storage hydropower and sustainable electrification.

Electrical transformer substations are infrastructures that transform the electrical energy transported at medium voltage into low voltage for consumption by end users.

The earthing system is an invisible but essential element for ensuring electrical safety at home, at work or in industrial environments. Although it often goes unnoticed, its correct installation can make all the difference in the event of a fault or current deviation. Here we explain what an earthing system is for, its main components, how to identify it and the key aspects of its maintenance and verification.

The International Day of Light, celebrated every 16 May since 2015, is a global initiative supported by UNESCO aimed at highlighting and celebrating the importance of this resource in the development of all areas of human life. At the Iberdrola Group, as a corporation that promotes electrification on a global scale, we join this celebration to raise awareness of the value that this unique resource brings to people everywhere.
