Co-Generation Power Plant Ecoenergía (‘EcoEnergía’)

EcoEnergía is a co-generation power plant located in TGS (‘Transportadora de Gas del Sur’)’ General Cerri Complex in Bahía Blanca, Province of Buenos Aires. The plant, consisting of a steam turbine with a power capacity of 14 MW, was commissioned in 2011. The plant sells electricity in the Energía Plus market. From 2011 to 2017, EcoEnergía’s average annual generation amounted to 84 GWh, with a generation record high of 102 GWh in 2016, and a record low of 20 GWh in 2011.

It is worth highlighting that this power plant consists in unconventional renewable electricity generation through the use of the residual heat from exhaust gases (450ºC) coming from three gas turbines located at the Fiat compression plant in TGS‘s General Cerri Complex. For its functioning, a set of ducts were installed to collect the effluent gasses from the 3 gas turbines, a gas recovery boiler, a steam turbine, and a 33 kV 10km-long medium voltage line to transport the generated electricity to Chañares Substation.
