part of the request for a Production License to be made by the producer to the Directorate-General of Energy and Geology (DGEG), as set out
in Decree-Law No. 172/2006 of 23 August, with additional legislation in Decree-Law No. 215-B of 8 October.

However, the conditions for the construction of elements for connection of the production facilities to the network are established through an agreement between the parties.
For connections to installations using VHT, the network operator is required to create access conditions.
The respective expenses are the responsibility of the applicant. The construction conditions shall be agreed between
the applicant and the network operator.
Due to reasons relating to network quality of service, reliability and safety, RNT users (VHT producers and clients)
are required to comply with the provisions of the
