In the Province of Neuquén, CTLL is located at Loma de la Lata, near what used to be one of the largest gas fields in Latin America known by the same name. Commissioned in 1994, it has a 780 MW capacity, 1.8% of Argentina’s installed capacity, and consists of three 125 MW GE GTs, a 180 MW Siemens ST installed in 2011 for its closing to CCGT and repowered in January 2018, two 105 MW GE aero-derivative GT, installed in May 2016 and August 2017, and 15 MW from MAN gas engines commissioned in August 2021. From 1997 to 2024, the average annual generation was 2,475 GWh, with a record high of 5,103 GWh in 2022 and a record low of 272 GWh in 2002.
After suffering a failure in 2023, GE GT05 was reinstated at the end of January 2024, failing again in August 2024. Therefore, it operated with a used power turbine until December 2024, when the repaired turbine was installed. Pampa is taking the appropriate steps with GE to minimize the economic impact of these failures resulting from the breach of availability commitments under PPA.
