In Royal Decree 900/2015 the Government banned shared self-consumption. The Generalitat of Catalonia appealed part of the Royal Decree for invasion of powers in February 2016, and now the Constitutional Court has partially given it a reason.
The Generalitat of Catalonia presented a conflict of powers before the Constitutional Court against various articles of the Royal Decree, of which the TC has only accepted that the decree encroaches on Catalan powers in a section of article 4 and articles 19, 20. , 21 and 22, which overrides. This new ruling gives the green light to shared self-consumption and is closer to the change in the energy model that must be encouraged by 2020-2030, because the European law already explicitly recognizes the "right of all citizens". to generate, store, consume and sell its own renewable energy under fair conditions. "
This Royal Decree, moreover, was in opposition to the European Directive 2010/31, which stipulates the obligation of public administrations to take measures to ensure that all public buildings are built under parameters of maximum energy efficiency from 2018 and , from 2020, all buildings. Given that Spain is a country where most people live in communities, shared self-consumption is an essential tool for this energy model change.
After this sentence, theoretically anyone can share a self-generation system with a neighbor, but for practical purposes it is still prevented by the configuration of the electrical networks of the self-consumption systems, because it is not regulated that several consumers share the same power generation system.
There is still much to be done, but this ruling by the Constitutionalist indicates that we must continue in this direction in order to reach a new energy model, in which shared self-generation has an important role.
