What Prolux does

Prolux – Engenharia de Sistemas is a privately held Brazilian electrical engineering firm founded in 2004 and headquartered in Porto Alegre (São Geraldo), Rio Grande do Sul, with additional offices in Campinas (São Paulo) and Aparecida de Goiânia (Goiás). The company specializes in energy measurement systems, substation protection and control, and turnkey engineering services for the Brazilian electrical sector, acting as a certified Schneider Electric EcoXpert partner at Master level for Power Automation, with additional certifications in Power Management and Power Services. Its portfolio is anchored on Schneider's Digital Power and EcoStruxure platform: ION-series revenue-class meters (ION8650, ION7400, ION9000) for frontier and billing measurement; PowerLogic protection relays (P1, P3, P5, P7, MiCOM P30/P40, A1/A3) for medium- and high-voltage applications; Easergy RTUs and bay controllers (T150, T300, T500, MiCOM C264, Saitel DP) for substation automation; and active harmonic filters (AccuSine PFV+/PCS+, EasyLogic APF). Software offerings center on PME for energy management and EPO (EcoStruxure Power Operation) for SCADA supervision.

Beyond hardware distribution, Prolux delivers integrated systems and services including SMF (Sistema de Medição para Faturamento) turnkey implementation, retrofit, and INMETRO-traceable calibration; SPCS (Proteção, Controle e Supervisão) solutions; ERAC (Regional Load Relief Scheme) for grid stability; SMSF (synchrophasor measurement using PMUs); and engineering services spanning feasibility studies, basic and executive projects for substations and transmission lines, owner's engineering, and connection studies to the National Interconnected System (SIN). The firm serves a diversified mix of electrointensive industrial consumers (GERDAU, Petrobras, BRASKEM, WEG, BRF, Via Varejo), generation companies (ENGIE, ITAIPU, FURNAS, ENEVA), and transmission/distribution utilities (COPEL, ISA CTEEP, ENERGISA), as well as EPC contractors (ELECNOR) and energy traders migrating clients to the free energy market.

The business model combines hardware and equipment resale (Schneider products) with project-based engineering services, multi-year calibration and maintenance contracts under INMETRO-mandated 5-year cycles, and modernization/retrofit work that migrates clients from reactive to condition-based maintenance. Revenue is quote-based and project-specific, with no publicly disclosed pricing tiers. Distribution is exclusively through direct enterprise sales across Brazil's 27 states, with no public revenue, headcount, or ownership disclosures.

Recent moves5 records

Expansion highlights4 records

Broad incumbents

• Siemens: Global industrial automation and smart-infrastructure OEM with direct presence in Brazil offering SICAM, Siprotec, and EnergyIP products overlapping with Prolux's measurement, protection, and SCADA portfolio. Competes for the same substation, generation, and large-consumer mandates.
• Schneider Electric: Global energy management and automation OEM whose ION meters, PowerLogic relays, Easergy RTUs, and EcoStruxure platform constitute Prolux's entire product stack. Comparable as the upstream technology partner that also sells direct to large Brazilian accounts, defining both Prolux's opportunity and competitive threat.
• ABB: Global electrification and automation supplier selling Relion protection, RTUs, and energy management systems directly to Brazilian utilities and electrointensive clients. Overlaps with Prolux's product lines and competes for major SMF/SPCS tenders.
• Hitachi Energy: Provider of grid automation, protection, and digital power solutions with operations across Latin America, including Brazil. Directly competes on substation automation, RTUs, and energy management software against Prolux's Schneider-based offerings.
• Eaton: Global power management manufacturer with metering, protection, and switchgear lines (Power Xpert, Edison) overlapping Prolux's portfolio. Has local Brazilian operations and competes in industrial substation and free-market migration deals.
• GE Vernova: Power and grid solutions arm of GE offering protection relays, GIS, and grid software (GridOS, EMS) globally including in Brazil. Competes in high-voltage substation, generation, and transmission projects similar to Prolux's ENGIE, FURNAS, and ISA CTEEP mandates.

Emerging players

• Rockwell Automation: Industrial automation and information platform (Logix, FactoryTalk) with growing presence in Brazilian energy and infra. Partial overlap in SCADA, automation, and energy management adjacent to Prolux's PME and EcoStruxure deployments, but stronger on discrete manufacturing.

Regional players

• WEG: Brazilian electrical equipment leader in motors, drives, and increasingly power systems, digital panels, and substations. Overlaps with Prolux on switchgear, automation, and protection tenders in Brazil, while also appearing on Prolux's customer list.

Direct peers

• Schweitzer Engineering Laboratories (SEL): US-based protection relay and automation specialist whose SEL-451, SEL-487B, and synchrophasor products are direct substitutes for PowerLogic P-series relays and SMSF systems. Competes head-to-head for utility and industrial substation protection mandates in Brazil.

Others

• Wago: Supplier of automation, interface, and control-cabinet products used inside Brazilian substations and energy cabinets. Adjacent complement to Prolux's SPCS deployments rather than a direct competitor on billing measurement systems.
