Power Plants and Technology
First-class technology for efficient and responsible power generation
Araucaria Energy and SPI Energy have four power plants strategically located a few kilometers from the City of Buenos Aires. Araucaria Energy operates three plants -Las Palmas, Matheu and Luján- and SPI Energy operates San Pedro, which is being converted to combined cycle with the first phase of the work already completed.

San Pedro Thermal Power Plant
Location: 164 km NW of the City of Buenos Aires
Start up: February 7, 2018
Generation capacity: 103.5 MW
SPI Energy was awarded, through Resolution 287/17, with a new PPA of 105 MW for the expansion and conversion to combined cycle of its San Pedro power plant. The expansion work is currently being carried out with the 1st phase of the work completed and enabled, totaling 50.5 MW capacity, and the 2nd phase under execution. With the completion of the works, the total installed capacity of the plant will be 208.5 MW.
This plant will operate in combined cycle with a 3 x 1 configuration consisting of 3 (Siemens SGT-800) gas turbines and 1 steam turbine.
The power plant is adjacent to the San Pedro Transformer Station, owned by TRANSBA (concessionaire of the power transmission system in the Province of Buenos Aires) directly connected to the 132 kV line through the transformer station.
Works in Progress
Expansion and conversion to combined cycle project: 105 MW. -1st phase of 50.5 MW with business license and 2nd phase under construction.
Total projected generation capacity: 208.5 MW
How the combined cycle works
The combined cycle consists of capturing waste heat from the three gas turbines and producing steam in three boilers that will feed the new steam turbine, allowing additional power generation without extra fuel.
Las Palmas Thermal Power Plant
Location: 90 km NE of the City of Buenos Aires
Start up: April 20, 2018
Generation capacity: 202 MW
The power plant has a configuration of 4 Siemens SGT-800 simple cycle gas turbines with a generating capacity of 202 MW.
It is adjacent to the Las Palmas Transformer Station, owned by TRANSBA (concessionaire of the power transmission system in the Province of Buenos Aires) directly connected to the 132 kV line through the transformer station.
Matheu Thermal Power Plant
Location: 56 km NW of the City of Buenos Aires
Start up: May 22, 2018
Generation capacity: 254 MW
The power plant consists of 4 Siemens TRENT 60 gas turbines generating 254 MW.
It is adjacent to the Matheu Transformer Station, owned and operated by Edenor (the largest power distribution company in Argentina in number of customers). It is directly connected to the 220 kV line through the transformer station.
Lujan Thermal Power Plant
Location: 68 km NW of the city of Buenos Aires
Start up: May 30, 2018
Generation capacity: 127 MW
The power plant consists of 2 Siemens TRENT 60 gas turbines with a 27 MW total generation capacity.
It is adjacent to the Lujan II Transformer Station, owned and operated by TRANSBA (concessionaire of the power transmission system in the Province of Buenos Aires). It is directly connected to the 32 kV line through the transformer station.
Our Technology
Quality, power, performance and maximum efficiency
Based on the proven capabilities of the technology we use, the power plants operate with high reliability and availability.
Siemens SGT-800 gas turbine
The Siemens SGT-800 gas turbine offers wide flexibility in fuels, operating conditions, maintenance concepts, overall solutions and rating. This turbine operates at the Las Palmas and San Pedro power plants and combines a robust and simple design with high reliability and easy maintenance, as well as high efficiency with low emissions.
Easily adaptable to the combined cycle, the turbine can operate at full load in less than 25 minutes after a hot start, making it also available as backup equipment in renewable-based power generation.
Main features:
- High electrical efficiency with low deterioration.
- Adaptable to different operating and functioning schemes.
- Requires low pressure of the gas supplied.
- High level of exhaust gases, achieving an excellent environment for cogeneration or combined cycle.
Siemens Industrial Trent 60, the most advanced gas turbine for industrial use
Used at the Lujan and Matheu power plants, the Siemens Industrial Trent 60 is the most advanced gas turbine currently available for industrial use, producing up to 66 MW with a performance of almost 42%.
The aeroderivative gas turbine with Rolls Royce Aero Engine technology has set a new benchmark in terms of power output, fuel and cost savings, with its short delivery and installation times and smooth operation.
Main features:
- Flexible aeroderivative power: start and restart in less than ten minutes with multiple start capability.
- Reduced support surface and light weight.
- Optimal performance proven by the aeronautics industry.
- Complete maintenance in less than 24 hours.
- Highest efficiency single cycle gas turbine.
