Argentina's Pampa Energía aims to extend its Loma La Lata thermal power station, located in the country's Neuquén region. The construction works will take the project to 652 MW on completion.
El Cronista newspaper said the new installations at the plant must be finished by mid-2015.
At present, Loma La Lata has an installed capacity of 537 MW.
Since the end of 2010 the plant has worked as a combined-cycle station, which required an investment of $1bn. Before that, the station featured three 125 MW turbines.
