Trialog

What Trialog does

Trialog is a French engineering and consulting firm specializing in interoperability standards for smart grid, electric mobility, and IoT cybersecurity ecosystems. Founded in 1987 and headquartered in Paris (25 rue du Général Foy, 75008), the firm serves utilities and Distribution System Operators (DSOs), EV charging infrastructure operators and station manufacturers, automotive OEMs, and smart city initiatives across Europe, the Middle East, Asia, and Africa. Its core technology focus is a narrow but deep stack of communication protocols — G3-PLC (ITU-T G.9903), OCPP, ISO/IEC 15118, and DLMS/COSEM — augmented by an in-house Privacy and Security Plan methodology. The company is a founding and executive member of the G3-PLC Alliance, an active contributor to the Open Charge Alliance and IEC standardization work, and the coordinator of multiple EU Horizon 2020 research projects including PDP4E, Interflex, and PRIDE.

The firm monetizes through four revenue streams: engineering and consulting services (often delivered within EU-funded R&D consortia), modular training programs (G3-PLC, DLMS/COSEM, OCPP, ISO 15118) delivered by named technical experts, licensed software tools (ComboCS CCS tester, OCPPvs simulator, EVCC and CSMS software stacks, G3 Lab Tools), and standards validation and certification support. Pricing is custom-quoted; training is delivered to groups of up to 10 attendees in English or French at the Paris office or on client sites. The go-to-market is enterprise field sales supplemented by event-driven thought leadership (European Utility Week, EVS32, Nordic Edge Expo), EU consortium participation for pipeline generation, and standards-body membership as a credibility channel.

Trialog operates TriLab, an internal innovation laboratory founded in October 2018 that researches digital twins, blockchain for eMobility, LoRaWAN, augmented reality, and semantic interoperability. The firm has supported Enedis's Linky smart meter program since 2007 (35 million G3-PLC meters deployed), partnered with Renault on V2G and Plug&Charge demonstrations, and participated in projects such as ENERGICA (Kenya, Madagascar, Sierra Leone), demonstrating a deliberate geographic and vertical broadening. Trialog is privately held as a French Société par Actions Simplifiée (SAS) with €722,000 share capital and no disclosed external investors.
