The public consultation procedure was introduced by the Energy Services Regulatory Authority (ERSE), when its activity began in 1997. Meanwhile, since 2002, the public consultation was legally established in Decree-Law nr. 97/2002 of the 12th of April
which approved ERSE's statutes.
According to this practice, all the changes in the codes are preceded by a public consultation process which involves the participation of the stakeholders including regulated companies, consumer representatives and institutional entities. The documentation for each public consultation is available on ERSE's Internet page. ERSE may include in the process a public hearing to get comments and suggestions, namely from the operators of the energy sector.
This practice of ERSE is, nowadays, common at the european level, and it is assumed that the high participation by stakeholders in the public consultations prove its role as an important tool to check strength and transparency to the regulatory decisions.
