With domestic supply and demand expected to grow in the coming decades, the prospects for the natural gas industry in Brazil are promising. However, the legal and regulatory frameworks will need to evolve to allow the country to reap the benefits of a competitive gas market. Through its Gás para Crescer initiative, the Brazilian government sets a plan to liberalise the local market further, building on previous market reforms in the country. This report is the result of a peer-review and dialogue process between Brazil and IEA member country experts and draws on European gas market reform experiences to develop practical recommendations for the implementation of gas market reform in Brazil. In particular, recommendations relate to establishment of independent transmission system operators (unbundling) and the design and implementation of operational and technical rules based on regulatory policies (network codes).
