The licensing procedure for electricity storage systems and general conditions of the agreement for restricted access to the network

The DGEG Order applies to storage facilities that use previously allocated injection capacity in the following situations:

1. where there has been a change in the technology of a photovoltaic solar power plant that has not been built but has an injection capacity reserve title (“TRC”);
2. in the case of a standalone or co-located storage system that uses:
   • renewable energy plant(s) with a TRC that was previously awarded through the general access modality;
   • small production units (i.e. power plants with an installed capacity of 1 MW or less) with a pre-existing registration;
   • self-consumption production units with an installed capacity greater than 1 MW and an injection capacity greater than 1 MVA

The Order also establishes the technical standards applicable to these storage facilities, as well as the obligation to provide system services.

Regarding the directive approved by the ERSE, it establishes the general conditions of the agreement to be entered into between the owner of a power plant or storage facility (or the corresponding representative) and the network operator, when projects are authorised with restrictions on the maximum power to be injected into the network.
