Genelba Thermal Power Plant (‘CTGEBA’)

CTGEBA, located in the district of Marcos Paz, in the Province of Buenos Aires, has a strategic location since it is just one kilometer from the Ezeiza transforming station, a WEM (‘Wholesale Electricity Market’) reference node for the supply of electricity to the country’s highest demand area. CTGEBA began operating in 1999 and has two CC (‘combined cycle’), one with 684 MW installed capacity, consisting of two 223 MW gas turbines each, and a 239 MW steam turbine, repowered in October 2020. The second CC consists of a gas turbine with a 182 MW power capacity, known as Genelba Plus, installed in 2009 and repowered in June 2019, another gas turbine of 188 MW installed in 2019, and the 199 MW steam turbine commissioned on July 2, 2020, completing the expansion project started in 2017.

CTGEBA is one of the largest thermal power plants in the country, with a total installed capacity of 1,253 MW, representing 2.9% of Argentina’s installed capacity. From 2000 to 2023, its historical average annual generation was 5,294 GWh, with a generation record high of 8,594 GWh in 2021 and a record low of 3,438 GWh in 2001.
