Techint E&C participated in the inauguration of the San Alonso Thermal Power Plant, achieving a milestone in renewable energy

Published 23.7.2025

The company provided key technical diagnostic, early engineering and detailed engineering services for this biomass plant, which is driving the energy transition in Argentina.

 

On May 7, the official inauguration of the San Alonso Thermal Power Plant (CTSA) took place in Gobernador Virasoro, Corrientes. It marked the completion of a project in which Techint Engineering & Construction was involved from its initial stages. During the event, company representatives shared this milestone with Luciano Baroni, CEO of CTSA and FRESA, Manuel Sobrado, Executive Director of Grupo Insud, and other key figures in the energy sector.

With an installed capacity of 40 MW, the plant is now operational and connected to the national grid, providing renewable energy from biomass.

“Returning to the site, with the plant operational and generating energy at full capacity, is a source of enormous satisfaction,” said Sara Couso, Power Plants Principal and technical coordinator of the project.

 

A path of engineering and collaboration

Techint E&C's participation began in October 2021 with a technical survey at the Garruchos Thermal Power Plant, a neighbouring plant owned by FRESA, which shares infrastructure with CTSA. At that time, construction of the new plant had not yet begun, nor did it have a defined engineering design.

Since then, the project has been structured into three phases: technical diagnosis focused on improving the existing plant; early engineering for CTSA, which included document analysis and the preparation of a Class IV CAPEX; and detailed engineering, which required more than 121,500 hours of work.

The detailed engineering was carried out under a multi-site collaborative scheme, with professionals from Argentina, Brazil, Spain, India, Mexico and Ecuador. Carlos López Jimenez, Power Plants Manager, led the project from the Seville office, while Sara Couso coordinated the technical tasks locally.

“The most valuable thing of all is knowing that the client is fully satisfied with our work. This is undoubtedly the greatest recognition we can receive as a team,” said López Jimenez.

 

Renewable energy and commitment to the environment

The San Alonso Thermal Power Plant is considered one of the most modern of its kind in Latin America. Its operation contributes to a more sustainable energy matrix thanks to the use of biomass, a renewable fuel that is CO₂-neutral.

This type of technology uses biodegradable waste from forestry, industry and agriculture to generate thermal energy efficiently and with less environmental impact. Its implementation reduces greenhouse gas emissions and advances global commitments to combat climate change.

“The event marked the conclusion of an extraordinary project, and we are deeply proud of the work carried out by our entire team,” concluded Couso.
