2  National Context

The national overview of electricity brings data from the Brazilian electricity market and addresses issues such as installed capacity, electricity generation, number of electricity generation projects by source, extension of transmission lines, load, maximum demand, indicators of electricity supply continuity, average prices and tariffs, consumption and number of consumers associated with the largest distributors, as well as agents by type and government programs and eletric vehicle data.

The data sources used in this chapter are the institutions ANEEL, EPE, ONS, CCEE and MME. ANEEL contributes with the information on average tariffs, indicators of electricity supply continuity (DEC and FEC), and the number of electricity generation projects by source. The data related to installed capacity and electricity generation are extracted from the Brazilian Energy Balance (BEN), while the information on consumption and number of consumers is provided by the electricity sector agents directly to EPE’s SIMPLES system.

The ONS provides data on the length of transmission lines, maximum demands, energy load, and the level of generation curtailment by source and subsystem. The Electric Energy Trading Chamber (CCEE) provides data on the Difference Settlement Price (PLD) by subsystem and the Number of Agents by type. Data on electric vehicles is obtained from the Brazilian Electric Vehicle Association (ABVE). Finally, data from the Luz para Todos Program is obtained from the Ministry of Mines and Energy (MME).
