Green Tech supports its customers on Reunion Island in the following areas

Support for energy demand management (EDM)

+262(0) 262 010 317

Day-to-day support, at site or park level

Tracking / Identification

monitoring energy consumption, identifying and implementing energy efficiency actions (optimizing settings, changing equipment, changing usage) and detecting any deviations.

Follow-up / Organization / Maintenance and support

follow-up and organization of preventive and corrective maintenance, assistance in the event of operating anomalies, identification and implementation of energy efficiency actions.

→ Help with grant applications.

CEE, ADEME, Region, FEDER, BPI France, EDF... There are many ways in which you can help reduce your electricity consumption or, more generally, contribute to the energy efficiency of your sites.

Project assistance (AMO) for energy-related projects


support for design offices, organization and monitoring of work, acceptance, fine-tuning and optimization.

Instrumented energy audit

+262(0) 262 010 317

As the first step in managing energy consumption, an energy audit enables you to define an effective action plan with a rapid return on investment.


→ installation of measuring equipment (1 week to 1 month) in order to carry out an "inventory" of the installation

Identification & assessment

→ identification and assessment of potential savings (cost and savings potential)

Support & implementation

→ support for the implementation of selected actions

Instrumented audit (15 days in summer, 15 days in winter on each site) on 6 tertiary buildings belonging to Sodiac with the aim of identifying the share of the main uses in the site's consumption and the potential for savings on electricity consumption.

BUNGALOW programme

The CEE Bungalow programme focuses on the energy savings inherent in the operation of tertiary buildings, particularly those in the hotel sector (which are particularly energy-hungry) in Réunion 974 and Mayotte 976.


Instrumented audit with assistance in setting up actions and raising awareness among site users. The Kabardock is a concert hall on Réunion Island, in the town centre of Le Port.

Photovoltaic production

+262(0) 262 010 317


As an expert in energy management, Green Tech offers self-consumption power plants (after optimizing consumption).

sizing of the plant according to residual electricity demand, third-party investment, operation and monitoring of production over its lifetime


In some cases, self-consumption is not appropriate, so Green Tech offers power plants that sell electricity back to EDF.

plant sizing, third-party investment, operation and lifetime production monitoring

Self-consumption PV installation at Hyper E. Leclerc les Terrass in Saint-Joseph

Green Tech is an integrator and investor in self-consumption PV installations. All the parties involved (Green Tech, Leclerc and CBO) work together to optimise PV production.


Self-consumption photovoltaic installation at Hyper E. Leclerc La Réserve in Sainte Marie

Green Tech is an integrator and investor in PV power plants. Thanks to self-consumption photovoltaics, the shop consumes less electricity from the EDF grid.

Photovoltaic installation for resale in Le Port

This project is currently under construction following a call for tenders issued by the CRE (Commission de régulation de l'énergie). The electricity produced will be fed into the grid and used by EDF to power buildings (homes and businesses) in the surrounding area.

Tertiary Decree

+262(0) 262 010 317


Green Tech offers assistance with the Tertiary Eco Efficiency Scheme (DEET), also known as the "Tertiary Decree".

Declarations on the OPERAT platform are compulsory for all commercial buildings or premises with a floor area of 1,000 m² or more.

There are reporting obligations, but also targets to be met by 2030, 2040 and 2050.

Depending on the customer's needs, the actions will be :

→ the implementation of a strategy for declaring CPEs (Reporting Functional Entities) between landlords and tenants

→ creation of a user account for access/declaration on the OPERAT platform, and EFA declarations

→ data analysis to define the "best strategy" for declaring consumption in the light of consumption, possible sub-activity, usage intensity indicators, etc.

→ The declaration of consumption by the EFA (Reporting Functional Entity) for the reference year,

→ Annual monitoring to declare the year's EFA consumption and update the EFA.
