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

CTLL is located in Loma de la Lata, in the south of the Province of Neuquén. The plant was built in 1994 and consists of three gas turbines with an installed capacity of 375 MW, a 180 MW Siemens steam turbine installed in 2011 for its closing to combined cycle and repowered in January 2018, a 105 MW GE (‘General Electric’) aeroderivative 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 765 MW, which represents 1.9% 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 2019, the average annual generation was 1,993 GWh, with a record high of 5,096 GWh registered in 2019 and a record low of 272 GWh registered in 2002.
