For this first period, the Superintendence of Operations Abroad has set forth the priorities as follows:

Interconnect new sources of energy in Latin America with the Brazilian power system;

Promote the energetic integration between Brazil and the countries of Latin America; and

Prospect opportunities for investment in power energy in other countries to benefit the Brazilian economy by generating new markets for the goods and services suppliers segment.

The Superintendence of Operations Abroad has been developing negotiations with several countries in Latin America and Africa:

Angola and Namibia – Feasibility Studies of the AHE from Baynes, located in the Cunene River, in the border between the two countries;

Argentina – AHE Binacional de Garabi;

Costa Rica – Technical Cooperation Agreement under analysis;

Nicaragua – Appraisal of AHEs from Boboke and Tumarim;

Peru – Analysis of feasibility for use of 15 AHEs, totalizing 20,000 MW;

Uruguay - New transmission lines expanding the already existing electric interconnection between the southern part of Brazil and Uruguay;

Venezuela – Studies for interconnection with the purpose of having an electric interchange between the two countries.

With Bolivia, Colombia, China, Ecuador, El Salvador, Guinea Bissau, Guyana, Morocco and Nigeria the contacts are in their initial phase.
