Self-consumption energy sharing models

E-REDES, in accordance with the provisions of the previous version of the Electricity Self-Consumption Regulation (RAC), presented ERSE with a proposal for a pilot project to test two rules for sharing energy in self-consumption, complementary to the rules for sharing through fixed or proportional coefficients that had been defined, and based on hierarchical algorithms and dynamic fixing of energy sharing.

Remove Margins

Remove Top margin of the component

Remove Bottom margin of the component

Following this proposal, ERSE approved the E-REDES Pilot Project on self-consumption energy-sharing models in September 2022, defining that the self-consumption projects participating in the pilot project would be approved by ERSE, and since then 6 projects have been approved.

With the new version of the RAC (Regulation no. 815/2023), the sharing models being tested in the pilot project are now part of the regulation and are defined as the Hierarchical Sharing Model (Article 31) and the Dynamic Sharing Model (Article 32). It should be noted that the regulation only introduces guidelines for these sharing models, leaving room for ERSE to approve the conclusions and proposals of the ongoing E-REDES pilot project.

Thus, according to article 46 of the RAC, collective self-consumption (ACC) or renewable energy communities (CER) that are interested in joining these sharing models now must do so by participating in the pilot project.

To do so, they must follow these procedures:

Dynamic sharing

Sign up via the collective self-consumption management reserved area (for EGACs with ACCs and RECs that are already certified and active) in the Energy/Sharing coefficients menu;

Hierarchical sharing

Sending an e-mail to the e-mail address projetopiloto.autoconsumo@e-redes.pt with the following information:

Type of installations that are part of the ACC or CER;
Identification of the collective self-consumption management organisation (EGAC);
Sharing model to be tested (hierarchical or dynamic).

It should be noted that participation in the pilot project is only possible for ACCs and CERs duly licensed by the DGEG and in operation.

For hierarchical sharing:

The model and format of the data to be communicated by EGAC for the purposes of setting up the hierarchical structure and the sharing methods to be applied within each group and between groups are defined in Collective Self-Consumption - Hierarchical Sharing and are characterised in the Coefficients, Constitution and Type of Sharing files.

For dynamic sharing:

The model and format of the data communicated by E-REDES to EGAC and to be communicated by EGAC to E-REDES, for the purposes of energy sharing, as well as the deadlines for communicating energy data and coefficients are defined in Collective Self-Consumption - Dynamic Sharing and are characterised in the Coefficients files per pair of installations and Data made available to EGAC.
