Landaise Electrical Works Company

What Landaise Electrical Works Company does

Landaise Electrical Works Company (SLTE - Société Landaise de Travaux Électriques) is a French family-owned electrical contracting firm founded in 1976 and headquartered in Serres-Gaston, Landes. The company delivers four integrated service lines: industrial and tertiary electrical installation, maintenance and engineering; industrial automation based on PLC programming, SCADA systems, and measurement instrumentation; renewable energy development centered on solar PV (QualiPV-certified); and HVAC/energy-efficiency work (Qualipac-certified). Service delivery is anchored in a network of 8 regional agencies across France, supported by technology partnerships with Schneider Electric, Siemens, and Omron, and gated by a dense certification stack (ISO 9001, MASE, QualiPV, Qualifelec, Qualipac, EcoVadis).

The firm serves a dual customer base — small and medium enterprises (PME) as well as large industrial accounts — across diversified verticals including agro-food, petrochemical, aeronautical, automotive, and pharmaceutical. The business model is project- and contract-based: industrial maintenance contracts, electrical installation tenders, automation integration engagements, and renewable-energy project development. Revenue mechanics depend on long-cycle industrial work and on QualiPV-driven solar PV deployment, with no disclosed customer logos, no external funding, and an ownership transition completed in 2012 to the second generation (Edouard Serres and Hélène Dutrey).

With 51–100 employees and €500k registered capital, SLTE operates as a privately funded, mid-sized regional contractor that has used organic growth and service diversification rather than M&A to scale. Pricing is bid-driven on industrial tenders and project-scoped on automation and renewable work, with regulatory certification functioning as a gating mechanism for qualified French public and large-industrial procurement.

Core offering

SLTE (Société Landaise de Travaux Électriques) provides integrated electrical contracting services for industrial and tertiary clients in France, spanning electrical studies and engineering, installation, preventive and corrective maintenance, industrial automation (PLC programming and SCADA supervision), renewable energy installations (solar photovoltaic), and HVAC / climate engineering (heat pumps and ventilation). Founded in 1976 and headquartered in Serres-Gaston in Landes, the family-owned firm operates eight regional agencies and serves SMEs and large industrial groups in agro-food, petrochemical, aeronautical, automotive, and pharmaceutical sectors.

Product overview

SLTE (Société Landaise de Travaux Électriques) is a multi-service electrical engineering company offering integrated solutions across three core business lines: (1) Industrial & Tertiary Electricity services encompassing electrical studies, installations, and maintenance; (2) Industrial Automation covering process automation, industrial computing with PLC programming (Schneider Electric, Siemens, Omron) and supervision systems (WIN CC, PCvue), and measurement/instrumentation services; and (3) Renewable Energy & HVAC solutions including photovoltaic solar plant development and operation, plus heating/cooling systems with air-to-air heat pumps, air-to-water heat pumps, thermodynamic water heaters, and ventilation systems. The company operates as a services provider rather than a software product company, delivering custom electrical and automation solutions for industrial complexes and energy production facilities.
