About us
Since 2012

Green Tech history

GREEN TECH specialises in the innovative, eco-responsible field of energy efficiency, energy management and production. Energy management is a comprehensive approach aimed at improving a company's energy efficiency. energy efficiency. In practical terms, companies in Réunion can sustainably reduce their electricity bills and the associated environmental impact.

Since 2012

An independent company, Green Tech was set up to help companies on La Réunion deal with energy issues, which are far from their core business.

As part of a comprehensive service, Green Tech supports its customers in their day-to-day energy management (energy management actions -EMD-, instrumentation of electrical consumption -ICE-, energy reporting, preventive and corrective maintenance monitoring) and provides technical and financial support for Energy Efficiency -EE- projects.

In addition, Green Tech is a producer of cooling and electricity, on a third-party investment basis (cooling unit production plant, self-consumption photovoltaic plant).


Green Tech's positioning is quite unique. Where service providers traditionally offer one-off support, such as an energy audit, Green Tech provides a long-term service, ensuring that performance is maintained over time, with the aim of achieving energy efficiency.

Green Tech's added value for the project owner lies not only in its technical expertise, but also in its positioning as a third-party player alongside the project owner, acting as a catalyst to facilitate the implementation of actions in favor of better energy management and compliance with regulations.

Over the years, the company has opened up to various sectors (tertiary, healthcare, industry, tourism) and other activities (instrumented energy audits, innovative and research projects, photovoltaic solar power generation, refrigeration production, etc.).

The approach
Green Tech at your side

Our Approach


The energy transition we all want to see requires a profound transformation of our energy system, and innovation is a key pillar in achieving this.


We believe that changing current working practices in the energy field and getting everyone involved are real challenges if we are to achieve greater energy efficiency.


Optimising the operation of a facility, good operating practices and the choice of and the choice of equipment are key to achieving the best results in terms of energy management.

Renewable energy

For customers who want to go even further, Green Tech helps them to deploy green energy production systems.

Monitoring sites

The current challenge of the energy transition calls for innovation in better-adapted systems to achieve higher performance. Green Tech's missions are to diagnose and propose solutions.

Hundreds of thousands of euros saved

Managing energy demand is an essential pillar for making real financial savings, and Green Tech encourages, advises and supports its customers.

Thousands of tons of CO2eq avoided

Reunion's electricity is highly carbon-intensive. By avoiding consumption and installing low-carbon means of production, Green Tech and its customers avoid emitting thousands of tonnes of CO2 every year.
