We currently operate an installed capacity of 4,944 MW. By adding the next 295 MW expansions, our total installed capacity would amount to 5,239 MW. In only 15 years, we have maintained a policy of continuous growth and investment in the energy sector. Pampa contributes to the electricity market by operating eight thermal power plants, three hydroelectric power plants, three wind farms and a cogeneration plant.44
Wind Farm Engineer Mario Cebreiro
In May 2018, we inaugurated the Mario Cebreiro Wind Farm, which contributes 100 MW of renewable energy to the national grid. It demanded an investment of AR$3,000 million.
The wind farm, located just 20 kilometers away from Bahía Blanca, province of Buenos Aires, is composed by 29 wind turbines, each one with a total diameter of 126 meters. For the installment of these wind turbines, highly sophisticated works were undertaken on platforms and foundations similar to other wind farms of the same characteristics around the world.
The generators, coupled to the axis of the turbine (87 meters tall), generate electricity in 33 kV. Several internal collector circuits were installed and connected to two transformers of 132 kV. Consequently, the energy is delivered to the substation of Bahía Blanca, property of TRANSBA, located on the opposite side of provincial Route 51 (Ruta Provincial 51), in front of Mario Cebreiro Wind Farm.
This Wind Farm was the first from of such magnitude to be commissioned under Renovar 1.
In March 2019, we launched the wind farm “Parque Eólico Pampa Energía II”. It contributes 53MW of renewable energy to the national grid, and it demanded an investment of more than US$70 million.
This wind farm is our second wind energy project. It is located in an area named Corti, just 20kms away from Bahía Blanca city, province of Buenos Aires. The farm is composed of 14 wind turbines, each with a total diameter of 136m.
The generators attached to the turbine axis, with a height of 117 meters, generate electricity in 33 kV. Different internal collector circuits were installed and connected to a 132 kV transformer. Consequently, the produced energy is delivered to the electric substation Corti, owned by TRANSBA.
The second wind farm of the Company, located in a neighboring zone to Mario Cebreiro Wind Farm, was awarded under Resolution 281 to commercialize its energy in the Renewable Energy Term Market (MATER). Its power generation aims to serve large users, through contracts between private parties.
In July 2019, we inaugurated the wind farm “Parque Eólico Pampa Energía III” in the area of Coronel Rosales, contributing 53MW of renewable energy to the national grid. It demanded an investment of nearly US$70 million.
This is our third wind energy project in the area, along with wind farms Mario Cebreiro and Pampa Energía II. It operates with 14 wind turbines, each one of them built with a total diameter of 136m.
The generators attached to the turbine axis, with a height of 126 meters, generate electricity in 33 kV. Different internal collector circuits were installed and connected to a 132 kV transformer.
The third wind farm of the Company, was awarded under Resolution 281 to commercialize its energy in the Renewable Energy Term Market (MATER). Its power generation aims to serve large users, through contracts between private parties.

The plant has a privileged location, near to one the largest oil fields in Latin America also called Loma de la Lata. From 1997 to 2019, the average annual generation was 1,993 GWh, with a record high of 5,096 GWh registered in 2019 and a record low of 272 GWh registered in 2002.
In June 2019 we acquired the thermal power plant Ensenada Barragán along with YPF (50% each), located on a petrochemical area in Ensenada, province of Buenos Aires. The plant operates two open cycled gas turbines and has an installed capacity of 567MW.
Necessary operations are being carried out to convert the plant into a Combined Cycle, in order to increase the installed capacity up to 847 MW and achieve a higher level of efficiency, since it will generate 50% more electricity with the same level of fuel (gas) consumption.
Once the Combined Cycle operations are completed, it is estimated that Ensenada Barragán will become one of the most efficient thermal units within the country power grid.

The Genelba Thermal Power Plant is located in Marcos Paz, province of Buenos Aires, and has a total installed capacity of 1,243 MW. It has a combined cycle (composed by two gas fueled turbines and one steam turbine) and two gas fueled turbines. According to CAMMESA, Genelba´s plant was recognized as the most reliable combined cycle power plant in Argentina in 2008, 2009, 2010 and received the National Quality Award in 2013.
The plant consumes natural gas as fuel, produced in our own gas fields, and transported by TGS through a duct of 8km long and a 24” diameter, with a pressure of 60 bar.
We are currently expanding its capacity in 176MW by closing the second combined cycle of the plant.
Genelba Thermal Power Plant has an Energy Management System based on the international norm ISO 50001:2011, with an energy policy that states: “Genelba will assume the commitment to act carefully with energy efficiency, being reliable and responsible with energy consumptions regarding Power Generation Process activities and working with production systems that ensures the efficiency and reliability of the installations”.
This Thermoelectric Power Plant is located in the Industrial Park of Pilar, province of Buenos Aires. It was opened on August 31st 2017 and demanded an investment of US$100 million, generating 350 new jobs during its construction.
In addition to the installation of the plant, we built a gas pipeline and a new 132 kV underground line, both 3 kilometers long.

EcoEnergía is a co-generation plant, located inside Complejo General Cerri of TGS (Transportadora de Gas del Sur) in Bahía Blanca, province of Buenos Aires. It has a main steam turbine of 14MW, and started its commercial operations in 2011. The plant commercializes its energy in the Energía Plus market. From 2011 to 2019, EcoEnergía’s historical average annual generation amounted to 89 GWh, with a generation record high of 108 GWh in 2018, and a record low of 20 GWh in 2011.
It is worth mentioning that the plant generates non-conventional renewable energy through the use of residual heat of exhaust gases (at 450°C), which come from three gas turbines located at the compression plant in TGS´s General Cerri Complex. A set of ducts were installed to collect the effluent gases coming from the three gas turbines, a gas recovery boiler and a steam turbine. A 10km long, medium voltage (33kv) line was also installed to convey the generated electricity towards Chañares substation.
