About 3E

Founded in 1999 as a spin-off from the nanotechnology research center IMEC, 3E is a provider of software and consultancy services for the renewable energy sector. The company was established in Brussels, Belgium, by Luc De Gheselle and Werner Coppye. 3E offers solutions and guidance for sustainable energy projects throughout the entire project lifecycle.

The company's business model is split between consultancy services and software products, with a strategic goal to maintain a balance between the two revenue streams. Its client base includes project developers, asset managers, operators, investors, and policymakers. 3E has an international presence, with headquarters in Brussels and offices in locations such as London, Paris, Cape Town, and New Delhi, and a track record of projects in over 40 countries.

3E's core software offering is SynaptiQ, a SaaS platform designed to monitor, analyze, and optimize the performance of renewable energy assets, including solar, wind, and storage. This platform utilizes AI and physics-based digital twins to identify production losses, provide actionable recommendations, and improve financial returns. In addition to its software, 3E provides expert advisory services that cover technical, engineering, and strategic decision support for renewable projects.
