Piedra Buena Thermal Power Plant (‘CPB’)

CPB is located in the port of Ingeniero White, close to the City of Bahía Blanca, Province of Buenos Aires. The plant consists of 2 steam turbines of 310 MW each, totaling 620 MW, which represents 1.7% of Argentina’s installed capacity. The boilers can be indistinctly fed with natural gas or fuel oil.

The supply of natural gas is made through a proprietary 22-km gas pipeline, which is also operated and maintained by CPB, connecting with TGS (‘Transportadora de Gas del Sur’)’ main gas pipeline system. Furthermore, CPB has two tanks for the storage of fuel oil with a combined capacity of 60,000 m3. From 1997 to 2017, its average annual generation was 2,155 GWh, with a generation record high of 3,434 GWh in 2011, and a record low of 189 GWh in 2002.
