In 2011, the Basic Grid Expansions and Reinforcements Plan - PAR and the Annual Plan of Expansions and Reinforcements of Transmission Facilities not Members of the Basic Grid - PAR / DIT were issued, presenting the vision of ONS on expansions and reinforcements of the Basic Grid and in Other Transmission Facilities - DIT needed to maintain the proper performance of the grid, ensuring the full functioning of electricity market and allow free access to people interested in working in this market, within the horizon 2012-2014.

In order to allow the processing of the peculiarities of the BIPS, studies that give rise to PAR and PAR-DIT are conducted by Special Groups, with the participation of all agents, including the South, Southeast / Midwest and North / Northeast, the Energy Research Company - EPE, in order to provide transparency to the process and allow the participation of all interested parties.

PAR and PAR-DIT are sent to MME so that they come to be made consistent to the planning of the expansion elaborated by EPE. The proposed expansions and reinforcements in the basic grid and in Other Transmission Facilities, after compatibilization and validation by MME, are consolidated in specific documents and submitted to ANEEL, which will lead the process of granting or authorization for development of transmission projects.

For the implementation of expansions and reinforcements in the basic grid set out in PAR for the triennium 2012-2014 it is estimated an investment of approximately R$ 10 billion, considering the costs provided by ANEEL.

In the period 2012-2014, the expansions and reinforcements correspond to an approximate total of new additions - works without concession grant defined - of transmission lines in the order of 8700 km and 23,000 MVA of transformation capacity, listed in the tables below. These values ​​are the result of adding 29 lines and 97 new transformer units:

Among the major works proposed in this PAR to the basic grid, stand out:
