With this model, the electricity companies guarantee the customer that the energy consumed comes from renewable technologies
The ‘green’ energy marketed in Spain in 2021 increased by 12%, with a total of 122 million guarantees of origin issued in the year, corresponding to 122 terawatt hours (TWh), compared to 109 million the previous year , according to the statistical information related to electricity labeling published by the National Commission of Markets and Competition (CNMC).
Electricity labeling is based on the Guarantees of Origin system, the only valid tool for marketers to inform their customers on their monthly bills about the origin of the electricity they sell and its environmental impact. This mechanism prevents companies from developing misleading advertising strategies about the ‘green’ origin of their offers.
In 2021, 234 marketers participated in this system — compared to 247 in 2020 — accounting for 87% of all energy sold in Spain. In addition, during the year approximately 95% of the national production from renewable energy sources and high-efficiency cogeneration was supported by the System of Guarantees of Origin.
By contrast, the electricity of more than five million consumers, a record figure in recent years, was repaid. The reimbursement consists in the granting of certain guarantees to a specific electricity consumer and is carried out via the code identifying its point of delivery (CUPS) or, alternatively, via the NIF corresponding to several CUPS.
The administration of the System of Guarantees of Origin is the responsibility of the CNMC. It is an accreditation, in electronic format, that guarantees the volume of megawatt-hours (MWh) generated from renewable sources or high-efficiency cogeneration over a specified period of time.
The energy producers request the guarantees from the regulator and, once obtained, can transfer them to a national marketer or export them to a European marketer.
Last year was the first year that the CNMC electricity labeling was carried out. Changes have been made with this standard to update the labeling and adapt it to that of the surrounding European countries.
