Iberdrola leads the photovoltaic self-consumption market in Spain, managing 40% of the country's self-consumption customers. As part of its commitment to accelerating the energy transition and developing new products to improve efficiency and energy savings, in 2015 the company became the first company in its sector to integrate self-consumption solutions into its range of services.Iberdrola has consolidated its position as the benchmark company with a 75% increase in its self-consumption portfolio so far this year. Through Smart Solar, the company offers services for all types of customers, from domestic consumers to major industrial customers. In addition, the company has made self-consumption available to any customer, whether or not they have their own roof. In Spain, more than two thirds of the population live in high-rise buildings.To cover this segment, in 2019 the company launched its Solar Communities, through which several users can share their own 100% renewable energy from the same photovoltaic installation. Iberdrola's collective self-consumption solutions include turnkey installations and the possibility of placing the solar panels without prior investment, handing over the roof space to the company and facilitating access to the green energy generated to people living within a radius of 500 metres.The installation of a self-consumption solar system can lead to savings on annual bills of 30% in the case of residents' associations; 50% for companies and businesses; and up to 70% in single-family homes. These savings are produced in three ways: the energy produced by the installation that the user does not have to buy, the compensation for the surplus energy not consumed, which is fed into the grid, and the savings from lower taxes.
