LUBRISIDER S.A.

What LUBRISIDER S.A. does

LUBRISIDER S.A. is a privately held Argentine electrical infrastructure services company founded in 1992 and headquartered in General San Martín, Buenos Aires Province. The company delivers an integrated portfolio spanning the project, construction, and maintenance of transformer stations and substations up to 500 kV; installation and maintenance of extra-high, high, medium, and low voltage distribution lines; and medium/low voltage electroduct networks. Its flagship differentiated offering is in-service regeneration of dielectric transformer oil using Fluidex technology with reactivable Fuller earth, launched in 1995 and claimed to have regenerated over 10 million liters cumulatively, restoring oil properties to new-condition specifications without requiring transformer shutdown and generating less than 0.2% residual waste.

Supporting capabilities include transformer drying and filling, physical-chemical and dissolved gas chromatographic (DGA) oil analysis, oxidation inhibitor (DBPC) control, thermographic inspection, protective relay testing, and industrial electromechanical assembly. The company serves Argentine electric distribution and transmission utilities — notably EDENOR, EDESUR, EDELAP, and TRANSENER — as well as railway infrastructure operator ADIF, global OEM Siemens Argentina, and industrial clients including PIRELLI, AGUAS ARGENTINAS, and ENARSA.

The business model is professional services revenue earned through turnkey (llave en mano) EPC contracts and recurring service agreements procured via direct enterprise field sales. The company holds ISO 9001 certification (continuously since 2008) and OHSAS 18001/ISO 45001 certification (since April 2017), both audited by Bureau Veritas. With 59 employees, LUBRISIDER operates exclusively within Argentina and positions itself as a specialized, long-tenured technical services provider rather than a software or platform business.

Revenue model

1. Engineering, Procurement, and Construction (EPC) Services: Project, construction, and maintenance of transformer stations (up to 500 kV), high-voltage transmission lines, and medium/low voltage distribution networks. Revenue is earned through fixed-price project contracts and service agreements with utilities and industrial clients. Includes turnkey (llave en mano) delivery.
2. Transformer Oil Regeneration Services: On-site regeneration of insulating transformer oil for electric utilities and industrial operators. Provides ongoing maintenance service that extends transformer life without requiring oil replacement.
3. Testing, Commissioning and Maintenance Services: Electrical testing, commissioning, and corrective maintenance services for machines and electrical equipment, including transformer drying and filling, protective relay testing, and thermographic inspection.

Core offering

LUBRISIDER S.A. provides construction and maintenance of high-voltage transformer stations up to 500 kV, in-service insulating oil regeneration, distribution line assembly and maintenance, and industrial electromechanical assembly. Its primary clients are Argentine electric utilities (EDENOR, EDESUR, EDELAP, TRANSENER) and industrial customers, with operations conducted under ISO 9001 and ISO 45001 certifications.

Product overview

LUBRISIDER S.A. is an Argentine company founded in 1992 that provides an integrated service portfolio centered on electrical power infrastructure. The core offerings are: (1) Regeneration of insulating/dielectric oils in service using proprietary Fluidex technology with reactivable Fuller earth—a flagship service since 1995; (2) Project, construction, and maintenance of transformer stations up to 500 kV including civil and electromechanical works; (3) Installation and maintenance of distribution lines across all voltage levels (Extra Alta, Alta, Media, Baja Tensión); and (4) Medium and Low Voltage (MT/BT) electroduct and distribution network development. Supporting services include physical-chemical and chromatographic oil testing, transformer drying and filling, equipment commissioning, and industrial electromechanical assembly. The company operates as a services company rather than a software product company, serving utilities (EDENOR, EDESUR, EDELAP, TRANSENER) and industrial clients throughout Argentina.

Regional players

• Isolux Corsán: Spanish-headquartered infrastructure and EPC contractor with historical Argentine operations including high-voltage transmission projects. Direct regional peer for LUBRISIDER's substation and transmission EPC work in Argentina, though historically broader in scope (also roads and concessions).

Broad incumbents

• Schneider Electric: Global electrical equipment and digital automation provider with services for substations, transformers, and power distribution. Comparable to LUBRISIDER's MT/BT distribution and substation services, though Schneider's portfolio is far broader and increasingly software-enabled.
• Veolia: Global environmental services group with industrial waste oil collection and re-refining operations. Comparable to LUBRISIDER's used-oil circularity angle, though Veolia operates at much larger scale and across multiple industrial fluid streams rather than specializing in dielectric oil.
• GE Vernova: Major OEM of power transformers and grid services provider offering transformer lifecycle, oil processing, and substation services. Overlaps with LUBRISIDER's high-voltage substation EPC and transformer maintenance scope, though as part of a much broader portfolio.
• Siemens Energy: OEM of large power transformers and provider of transformer service and grid infrastructure solutions globally, including oil treatment and diagnostic services. Comparable to LUBRISIDER's substation EPC work (LUBRISIDER has historical Siemens Argentina project references) and oil regeneration capability.
• Toshiba Energy Systems & Solutions: Manufacturer of high-voltage power transformers and provider of associated lifecycle services including oil diagnostics and field maintenance. Comparable to LUBRISIDER's high-voltage transformer services, though Toshiba operates globally as a major OEM rather than a regional specialist.
• Mitsubishi Electric Power Systems: Producer of large power transformers and transmission systems with associated service and maintenance offerings. Comparable to LUBRISIDER's substation EPC and transformer maintenance work as part of a much broader power systems portfolio.
• SGB-SMIT: European-based transformer manufacturer with global service operations including transformer oil treatment and on-site maintenance. Comparable to LUBRISIDER's transformer lifecycle and oil service offering, though at significantly larger scale and with proprietary transformer manufacturing.

Direct peers

• Hitachi Energy: Global leader in transformer manufacturing and lifecycle services, including on-site oil filtration/regeneration for utility and industrial transformers. Directly comparable to LUBRISIDER's in-service dielectric oil regeneration and substation service offering, though at vastly larger global scale.
• Fluidex: Swiss provider of the Fuller earth-based dielectric oil regeneration technology that LUBRISIDER uses. Functions simultaneously as a technology licensor/partner and as a potential direct competitor offering the same regeneration capability in other geographies.
