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’) aeroderivative gas turbine installed in May 2016, installed in May 2016, the incorporation in August 2017 of a 105 MW GE gas turbine, and a 15 MW steam turbine repowering carried out in January 2018, its total capacity thus amounting to 765 MW, which represents 2% 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 2018, the average annual generation was 1,852 GWh, with a record high of 4,748 GWh registered in 2018 and a record low of 272 GWh registered in 2002.
