When we start taking measurements at the Power Supply Coupling Point (PAC), or rather, at the power input, we suspect problems related to the quality of the energy supplied. It is natural for many engineers, technicians, consultants and electrical experts to have some very coherent doubts, such as:
What is PRODIST?
Where does PRODIST apply?
What are the PRODIST modules?
There are many questions! And our initial measurement problem addresses only part of it, module 8 of PRODIST. This article aims to gather basic and essential information for those who need to understand the distribution procedures, their modules, and where each of them is applied.
What is PRODIST?
PRODIST These are the procedures for distributing electrical energy in the National Electrical System. They standardize the technical activities related to the operation and performance of electrical energy distribution systems and are made up of 11 distinct modules, of which we provide a summary of each one and to whom it applies.
What does PRODIST regulate?
The current ANEEL Normative Resolution No. 1,000 of December 7, 2021 establishes the rules for the provision of public electricity distribution services, setting out the rights and duties of all entities somehow connected to the grid. PRODIST is a complement to this resolution, standardizing and regulating technical, service, and commercial procedures, with annual reviews since 2008.
PRODIST Modules
PRODIST 1
Module 1 : PRODIST Glossary of Technical Terms;
Module 1 of PRODIST presents the list of the main terms, acronyms and expressions contained in the PRODIST modules, with their respective definitions, facilitating and standardizing understanding.

PRODIST 3
Module 3 : Connection to the Electric Power Distribution System;
Module 3 of PRODIST establishes detailed instructions and additional requirements on the regulation of connection, including distributed generation, to the electricity distribution system set out in the Rules for the Provision of the Public Electricity Distribution Service. It also provides details on the request for projects, connection budgets, and studies in specific situations.
Access Procedures: Conditions for connecting the unit to the network. | Technical and Operational Criteria: Design conditions for connection to the grid | Project Requirements: Substation and memorial projects |
Implementation of New Connections: Inspection and Approval by the distributor. | Operation and Maintenance Requirements: Guidelines for connection security. | Contracts: Defining the appropriate distribution contract. |
In particular, section 3.1 of Prodist module 3 provides instructions regarding Distributed Generation, which is a current trend. To comply with PRODIST in terms of microgeneration, pay attention to the guidelines in this module. This module provides forms and modules for those seeking approval for on-grid systems.
