Loma de la Lata Thermal Power Plant (‘CTLL’)

CTLL is located in Loma de la Lata, Province of Neuquén. The plant was built in 1994 and consists of three gas turbines with an installed capacity of 375 MW, a 165 MW Siemens steam turbine installed in 2011 for its conversion to combined cycle, a 105 MW GE (‘General Electric’) aero derivative gas turbine installed in May 2016, and the incorporation in August 2017 of a 105 MW GE gas turbine, its total capacity thus amounting to 750 MW, which represents 2.1% of Argentina’s installed capacity. CTLL has a privileged location due to its proximity to one of the largest gas fields in Latin America, also named Loma de la Lata. From 1997 to 2017, the average annual generation was 1,714 GWh, with a record high of 3,864 GWh registered in 2017 and a record low of 272 GWh registered in 2002.

Moreover, in January 2018 the 165 MW steam turbine increased its capacity to 180 MW, thus reaching a total installed capacity of 765 MW at CTLL.
