During the year 2017, Nexus Energía exclusively supplied to all its customers electricity of renewable origin, certified through guarantees of origin. The energy company has extensive experience in renewable energy. It is a leader in representing photovoltaic producers with a market share of 40% and almost 18,000 plants represented.

"Nexus Energía takes renewable energies in its DNA and we want to continue to be a benchmark in the energy transition of the sector, both in Spain and internationally," says Joan Canela, Group CEO, who expects growth in its renewable portfolio thanks to the new opportunities that are opening up in the generation market.

The leadership in the energy transition towards a clean model "will continue to be one of the pillars of the group's image" according to Alberto de Alvarado, Group Marketing Director who explains that "we detect a growing demand from the final customer, both companies and individuals. "The Group already has an energy company, Esfera Luz, whose guarantees of origin "come in their entirety from photovoltaic plants chosen by the customers themselves".

The Guarantee of Origin System is a system of certification of renewable energy backed by the CNMC (National Commission of Market and Competition). This independent body issues certificates of renewable origin, guaranteeing that the electricity supplied was indeed green. The certification process is done once the year is closed and the guarantees of origin are usually available during the month of April of the following year.

While it is true that all of the electricity produced in the Iberian Peninsula is mixed in the transport and distribution network, renewable energy certificates are a finite asset. The CNMC can only issue certificates for the total renewable production generated this year. This is a way of giving value to the production of renewable energy since if the demand for certified green energy is greater than production, its production will have to be promoted against polluting technologies.
