Electricity Sector in Argentina

The electricity sector in Argentina constitutes the third largest power market in Latin America. It relies mostly on thermal generation (54% of installed capacity) and hydropower generation (41%). The country still has a large untapped hydroelectric potential. The prevailing natural gas-fired thermal generation is at risk due to the uncertainty about future gas supply.

Faced with rising electricity demand (over 6% annually) and declining reserve margins, the government of Argentina is in the process of commissioning large projects, both in the generation and transmission sectors. To keep up with rising demand, it is estimated that about 1,000 MW of new generation capacity are needed each year. An important number of these projects are being financed by the government through trust funds, while independent private initiative is still limited as it has not fully recovered yet from the effects of the Argentine economic crisis.

The electricity sector was unbundled in generation, transmission and distribution by the reforms carried out in the early 1990s. Generation occurs in a competitive and mostly liberalized market in which 75% of the generation capacity is owned by private utilities. In contrast, the transmission and distribution sectors are highly regulated and much less competitive than generation.
