ONS participated as a lecturer in various international seminars sponsored by CIER, taking these opportunities to strengthen relations with other representatives of Latin America Operators, as well as to integrate the work being prepared under VLPGO with those from CIER.

In this context, stand out the II Seminar of Operation of Power Systems in State of Emergency, held in the Dominican Republic, and the 46th Meeting of Senior Executives at CIER, in Santiago, Chile.

ONS, as the Brazilian representative in the Working Group on Market Operators and Administrators of CIER, has been involved in the development of major projects such as the SIGER / Atlas, which aims at developing a data management system for regional energy integration and a geo referenced regional atlas.

Another highlight in 2011 the election of ONS General Director for the Presidency of CIER, in the period between November/2011 and November/2013, with the mission of strengthening the alliance towards the promotion of regional electric integration, especially in the scope of MERCOSUL countries.
