Brazil’s electricity market is huge and vast. It is the largest in Latin America and tenth largest in the world, with an installed capacity of 121,000 megawatts (MW). Brazil’s National Interconnected System (SIN) connects the entire country and, if superimposed over Europe, would enable Lisbon to sell energy to Moscow. It is one of the cleanest energy matrices on earth, with renewable energy contributing 47% of total energy production. Finally, it is a unique and evolving model with 2014 marking the tenth anniversary of the system of auction concessions launched as part of the 2004 reforms that followed the energy crisis of 2001. The “Brazilian model” has matured considerably over the past decade and is now respected globally for fostering competition. 2012, however, saw some major regulatory changes, which disrupted the electricity market and dampened the country’s economic outlook.
