Collective self-consumption

Collective self-consumption means a group of at least two self-consumers organised in condominiums of buildings under horizontal ownership or not, or a group of self-consumers located in the same building or area of apartments or houses, in close proximity, industrial, commercial or agricultural units, and other infrastructures located in a delimited area, which have a UPAC.

See the Self-consumption and CER Manual and learn more about the legislative guide for collective self-consumption.

In this context, the management of self-consumers is guaranteed by:

Collective Self-Consumption Management Entities (EGAC).
Renewable Energy Communities (CERs).
Citizens' Communities for Energy (CCE).

In the collective self-consumption regime, the commercial relationship is ensured by these entities, namely the relationship with the network operator for the purposes of paying the Network Access tariffs for self-consumption through the public network and also the relationship with the aggregator of surplus production for sale on the market.

In turn, the network operator is responsible for providing the data resulting from the calculation of the energy to be shared by the Consumption Facility or Self-consumption Facility associated with collective self-consumption, and for invoicing the applicable amounts under the legislation and regulations in force, in accordance with the Self-consumption of Electricity Regulation.

Collective self-consumption process

Collective self-consumption has three distinct phases in which there are various interactions between DGEG and the network operator:

As far as the Registration, Recording and Certification phases are concerned, the Collective Self-Consumption process follows the same procedures as Individual Self-Consumption. Visit the Individual Self-Consumption page and find out more about the topic.

Contracting

After certification by the DGEG and assignment of the collective self-consumption registration number, the EGAC establishes a contract for the use of the networks with the DSO, under the terms of the RARI and the RRC, when the configuration of the facilities participating in collective self-consumption results in the possibility of self-consumption through RESP.

In this context, EGAC will have to contact the network operator to sign the Network Use Contract, within the scope of the Electricity Self-Consumption Regulation, which you can consult here.

The Network Use Contract provides for the general conditions of the Network Use Contract (CUR), which can be consulted on ERSE 's website, as well as the specific conditions, made available by the network operator in a draft contract, which can be obtained by contacting apoio.autoconsumo@e-redes.pt.

Data

Energy data is made available to the different participants in the collective self-consumption process, as defined in the Electricity Self-Consumption Regulation, which you can consult here.

IC/IPR/IA holders, suppliers, EGACs and CERs will have access to data on a daily or daily/monthly basis, according to the image below.

Invoicing

The billing activity, with regard to access to the network (RESP), could be one of the following scenarios:

The energy consumed in the community's consumption facilities - produced by UPACs using the RESP - will be billed to EGAC.
Energy consumed in the community's consumption facilities - produced by UPACs without using RESP - is not invoiced.
The energy consumed in the community's consumption facilities - not produced by the UPAC but using RESP - will be billed to the Supplier.
EGAC is therefore responsible for paying the network operator the network access tariffs to be applied to self-consumption through RESP, as defined in the Collective Self-Consumption Regulation.
EGACs will be invoiced according to the calculations per Consumption Facility, taking into account the voltage level of the network to which the UPACs that supplied the energy consumed are connected, and invoices will be issued on a monthly basis and files will be sent with the respective details.
