Royal Decree 244/2019, of April 5, which regulates the administrative, technical and economic conditions of self-consumption of electrical energy, establishes these conditions for the modalities of self-consumption of electrical energy defined in article 9 of Law 24/ 2013, of December 26, of the Electrical Sector.
This law defines self-consumption the consumption by one or more consumers of electrical energy from production facilities close to the consumption facilities and associated with them.
The following types of self-consumption are distinguished:
a) Supply modalities with self-consumption no surplus. When the installed physical devices prevent the injection of any excess energy into the transportation or distribution network. In this case there will be only one type of subject, which will be the consumer subject.
b) Supply modalities with self-consumption with surpluses. When the generation facilities can, in addition to supplying energy for self-consumption, inject surplus energy into transportation and distribution networks. In these cases there will be two types of subjects: consumer and producer.
