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

In the south of the Province of Neuquén, CTLL is located at Loma de la Lata, in the proximity of one of the largest gas fields in Latin America, which holds the same name. The plant was built in 1994. It 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 -which capacity was increased in January 2018-, a 105 MW GE (‘General Electric’) aero-derivative gas turbine installed in May 2016, and the incorporation of a 105 MW GE gas turbine in August 2017 and 15 MW from MAN gas engines in August 2021. Therefore, CTLL’s total capacity is 780 MW, representing 1.8% of Argentina’s installed capacity. From 1997 to 2023, the average annual generation was 2,390 GWh, with a record high of 5,103 GWh in 2022 and a record low of 272 GWh in 2002.
