The operating profit dropped 69.4% year-on-year to ARS 26 million amid lower sales and increased costs. The sales revenues fell 5.4% year-on-year due chiefly to lower revenues from the spot market.

Endesa Costanera SA announced earnings results for the year 2008. The company reduced its loss to ARS 40.9 million in 2008 against a ARS 48.9 million loss in 2007. The loss was due to increased financial expenditures and devaluation of the Argentine peso against the US dollar, while the company's operating profit grew to ARS 82.4 million in 2008, up from ARS 37.3 million in the previous year. The better operating result was attributed to a 2.9% year-on-year rise of Argentina's electricity demand and to the 1.4% year-on-year increase of the company's power output. The net sales rose 12.6% to nearly ARS 1.479 billion due to increased revenues from domestic sales, generated from increased power generation and higher spot market prices.
