Code
The commercial relations between agents in the electricity sector is ruled by the Commercial Relations Code (Regulamento de Relações Comerciais - RRC) approved by ERSE, which currently covers both the electricity and the gas sectors, and applies across the entire national territory.
The Code covers the following main issues:
- Identification of stakeholders, activities and roles in the electricity sector
- Principles and general rules of commercial relations, including public service and universal service obligations
- Commercial relations between transmission and distribution grid operators, electricity producers and suppliers, namely for billing and payment purposes
- Customer relations (supply obligations, entering into a contract, invoicing and payment, as well as interrupting and restoring supply)
- Market scheme (contracting modalities, registration of agents, scheme of organised markets and bilateral contracting, choosing and switching supplier, monitoring framework for the operation of electricity markets)
- Commercial conditions for grid connection
- Measuring, reading,consumption and generation data provision
- Dispute settlement
The implementation of some of the rules established in the RRC depends on the approval of supplementary rules, of a more detailed and procedural nature. The approval of supplementary rules usually starts with the submission of justified proposals by regulated companies (as recipients of established obligations) and involves a prior consultation procedure, as well as seeking the opinions of ERSE’s advisory bodies.
Regulation No 827/2023 approves the Commercial Relations Code for the Electricity and Gas Sectors, repealing Regulation No 1129/2020, of 30 December. Previous Codes are made available online at ERSE’s Legal Instruments.
The Rectification Declaration Nº 830/2023, of 31 October, rectifies the Regulation Nº 827/2023, that approves the Commercial Relations Code for the Electricity and Gas Sectors.
