RTE international

What RTE international does

RTE international is the international subsidiary of RTE (Réseau de Transport d'Électricité), France's state-owned national electricity transmission system operator, and provides tailored consulting, engineering, training, and maintenance services to national transmission system operators and utilities worldwide. Founded as the cross-border arm of RTE, the company has delivered more than 200 projects across 40+ countries, with active engagements in Sub-Saharan Africa (Ethiopia, South Africa) and the Balkans (North Macedonia), among others. Its customer base consists almost exclusively of state-owned TSOs and large utilities, and a meaningful share of project origination is routed through development finance institutions, notably AFD and the French National Treasury, as well as bilateral government agreements.

The company's service portfolio is organized around seven interconnected lines: Système Électrique (electrical system expertise), Conseil aux organisations (organizational consulting), Électronique de puissance et études (power electronics and studies), Ingénierie (engineering), Solutions digitales (digital solutions), Maintenance, and the RTEi Academy training platform. Specialized modules layered on top include Technical Support, Audits, SERECT Certifications for live-working laboratories, and Turnkey Projects for live-line and substation work. Underlying technology assets include the HVDC Innovation Lab for high-voltage direct current research, the CONVERGENCE software platform for steady-state and dynamic grid studies (with the DYNAWALTZ module), AI/ML applications for grid optimization and renewable integration, and proprietary live-working (travaux sous tension) maintenance methods with associated safety procedures. The company holds ISO 9001 and ISO 45001 certifications.

RTE international operates a professional services business model. Revenue streams include long- and short-term technical assistance, turnkey project delivery, training through the RTEi Academy portal, audits, SERECT accreditation, and grant-funded technical cooperation programs financed by AFD and the French Treasury. Pricing is project-specific and quote-based; the company does not disclose standardized pricing. Go-to-market is dominated by direct enterprise engagement with national TSOs and government utilities, supplemented by participation in industry events such as the Africa Energy Forum, a corporate LinkedIn presence, and the RTEi Academy customer platform. Distribution is effectively bifurcated: direct enterprise sales for commercial engagements, and development-finance partnerships for grant- and loan-backed technical cooperation programs.
