Telefónica is expanding its decarbonization by committing to the construction of a gigantic solar installation at its largest logistics center in Madrid. Its completion would allow it to save up to 25 percent of its energy bill. Telefónica commissioned the photovoltaic development company ADC Ingeniería to handle the installation and operation of the rooftop power station which will be located at its main operational center in Spain. The new facility will produce around 470,000 kWh / year.
