The third-quarter net profit of Chile's largest power producer, Empresa Nacional de Electricidad SA (EOC, ENDESA.SN), dropped 18.7% on the year to 116.28 billion Chilean pesos ($232.1 million) from CLP142.99 billion a year ago.

The power generator's third-quarter revenue slipped to CLP628.95 billion, from CLP662.87 billion in the year-earlier period.

Endesa has 13,846 megawatts of installed capacity in Argentina, Chile, Colombia and Peru, and owns an equity stake in 987 MW of installed capacity in Brazil. Some 38% of Endesa's capacity is in Chile.

Endesa is controlled by power-holding company Enersis SA (ENI, ENERSIS.SN), which in turn is controlled by Spain's Endesa SA (ELEZF, ELE.MC).
