Our business

Altergie is expert in developing, implementing, financing and managing sun power facilities.

A sun power plant performance essentially relies upon some decisions taken at a very early stage: at the survey and design phase. Fully aware of these implications, Altergie is expert in every phases of projects development from pre-feasibility & feasibility studies:

  • Site selection and land use rights securisation
  • Compliance with urban planning by-laws
  • Environmental studies
  • Technical studies
  • Energy capacity studies
  • Power system connection or integration studies
  • Legal and financial structuring

Altergie seeks to optimize its technical, financial and environmental performances on all its assets in the long term. In all our projects, we ensure a substantive local dimension through partnerships with local communities allowing decentralized power generation to serve broader objectives such as improving public resources, contributing to environmental management, restoring agricultural practices, etc…

Altergie ensures coordination, coherence and continuity between each stakeholders and acts for its own account or for the account of third parties.

Altergie thoroughly focuses on large scale ground facilities and emphasizes on already artificialized land to install its facilities. (former quarry, motorway leftovers…)

Altergie also develops roofed sun power stations on farm buildings through a partnership with Solewa, agrivoltaic facilities in partnership with REM-TEC and floating solar PV plants in partnership with TotalEnergies.

Our expertise

Solar energy for local development

Developing solar plants

La phase de développement d’un projet The development phase of a PV project follows these four stages:
• Identifying potential sites
• Design & surveys
• Regulatory approval and permits
• Secure demand with an offtaker agreement

Production of photovoltaic electricity

Altergie manages renewable power assets:
• Production monitoring & control
• Corporate and business management
• Suppliers and equipment guarantees

Designing and surveying the Belvezet project : 

The solar photovoltaic plant in Belvezet (Gard- 30) was designed and developped by Altergie. Set up on local authority land, it features a total power output of 20MWc thanks to 78 700 solar panels covering 32 hectares. It is able to generate about 29 GWh of electrical power per year, representing the annual consumption of about 20 000 inhabitants.
This project results from and broad consultation between the municipality of Belvezet, states services and Altergie. It illustrates best-practice achievements on sustainable development components.
At the first steps, the municipality of Belvezet, landowner of a vast area, showed a strong political will to include the PV project in a global environmental effort to create a protected area of biodiversity over 600 hectares.
A biodiversity management charter was enacted ensuring the management of open areas and the restoration of agro-pastoralism on communal land. A grazing agreement on a total of 75 hectares was contracted with a local farmer to maintain or restore the grounds and respecting the soils and local biodiversity.
Thorough naturalist studies have been conducted ahead of the construction phase and are now still been carried out during the exploitation phase of the facility.
In addition to the plant capacity to provide a local and clean electricity power, this implementation reflects every stakeholder’s commitment to
associate renewable energy with broader efforts in favor of biodiversity and local development.

Agrivoltaïsm

The ambitious development objectives of the sun power sector in France lure some actors to considerably large areas of arable land to settle their PV plants. Altergie seeks to tackle this issue, not by supplanting land usage, but instead by using new sun power technologies allowing actual benefits for the agricultural crops. Therefore, Altergie has entered a partnership with Rem-Tec, a world leader in agrivoltaism technologies, which manage agrivoltaism facilities with PV modules and single-axis or bi-axis trackers above agricultural crops. These trackers are controlled by a smart connected monitoring software with agronomic data in order to actively manage and adjust shade, essential to crop growth..

Floating PV plants

Artificial water bodies such as former quarries represent a large potential for implementing floating PV plants. Various technologies are now been offered in this newly-emerging market.

Because of technological hazards for this type of projects, Altergie has partnered with TotalEnergies to target this specific market segment. New projects are now at a development stage.
