Biodiversity expertise: the new ally of industrial innovation?

For its project to develop a new gas storage station on its site in Ajaccio, ENGIE has included an unprecedented component for the active and committed protection of local biodiversity and has relied on the expertise developed by Storengy.

The "Biodiversity-team" of the Loregaz Project : Guy Mogenot ENGIE GPL, Denis Leca - Biodiversity Manager - Storengy, Pierre-Yves Maestracci - Biodiversity project manager - Storengy

ENGIE innovates to secure the gas storage site...

The Loretto site in Corsica is a SEVESO gas (LPG) storage site which supplies 16,000 customers in Ajaccio. This site has undergone profound changes since 2014.  The regulations covering SEVESO sites involve calculating the danger zones created by industrial activity and ensuring that they are controlled. ENGIE has thus proposed a solution consisting in building a new station, called Loregaz, where the new storage spheres would no longer be in the open air, but placed in sand-covered concrete cylinders in order to eliminate the risk of major damage by containing the effects within the perimeter of the site. Guy Mogenot, Director of the Loregaz project at ENGIE GPL: 


« By building a new gas station in Ajaccio, we are reducing our areas of effect. From one kilometer radius involving a population of over 8,000 people, we are moving to a 170 meter radius area requiring only a few window changes to not worry anyone. »

… and innovates to protect the environment in the long term.

The most novel and engaging chapter of the Loregaz project, however, lies in the aspect of environmental preservation and active protection of the site's biodiversity. Nowadays, to be granted a prefectural operating order, a company must not only provide impact studies (technological, health, sound) but also be in compliance with the "ARC" sequence resulting from environmental protection law. This text asks manufacturers not to disturb the species in the environment in which they are established by measures of Avoidance, Reduction and Compensation.

The land hosting the new Loregaz station is home to rare and protected species of orchids and turtles.

ENGIE has therefore undertaken to offset the effects of the construction of the new storage site by managing for the next 20 years 22 hectares of land conducive to the development of identified endemic species. For Guy Mogenot "it is a very strong commitment and, every year for 20 years, we will report to the State on the activity that we carry out, in relation to these compensation measures".
In order to best manage this delicate “ARC” sequence until 2038, ENGIE has partnered with the Conservatoire des Espaces Naturels de Corse (CENC). The conservatory teams first identified the twenty hectares of compensation land around Ajaccio conducive to the development of orchids and turtles to be protected. And for 20 years, CENC teams will monitor biodiversity on behalf of ENGIE.

Industry and conservatory of natural areas, two very different worlds working together to preserve biodiversity

Guy Mogenot willingly admits it: there are worlds between him, an industrialist, and the researchers at the Conservatoire des Espaces Naturels de Corse!

« I know how to talk about calculations, I know how to talk about industrial risks, but when I had to talk about the evolution of the turtle or how we do a census, a translocation or a transplantation, I was a little lost, hence the need to identify a person at ENGIE who can decode this language and these specific practices and act as an intermediary between me and the CENC "

Indeed, the notions of performance and time for an industrialist are almost the opposite of those of a researcher in biology: one is required to provide data quickly with a high mastery index, the other must respect the natural time of the species he studies and has per force learned to accept that one cannot completely control Nature. To allow these two worlds to dialogue, ENGIE's LPG department called on Denis Leca, Biodiversity Manager who has worked for Storengy for many years.

Denis has a major role in the advancement of the Loregaz project so that the commitment imposed by the State on ENGIE (to protect biodiversity for 20 years on Corsican land qualified and quantified by the CENC) is kept in a sustainable and optimal way. His first intervention was to recreate a link between the industrial team and that of CENC biologists.

Denis Leca and Pierre-Yves Maestracci, an intern working with Denis, succeeded by dint of patience, popularization – even translation – but also by transposing administrative requests into concrete action plans, understandable by all those who have to follow them.

Hermann's Tortoise is an endangered species that is the subject of numerous protection actions, particularly in Corsica. Its decline is mainly due to forest fires and urbanization, threat factors that have been on the rise for the past twenty years.


Serapias neglecta, and  Serapias parviflora are the two species of rare wild orchids identified on the Loregaz station host site that ENGIE has undertaken to protect on the compensation land, with the support of the conservatory of natural areas of Corsica (CENC).
This expertise, which combines industry and biology, quickly proved to be the determining factor in the success of the Loregaz project. Without it, ENGIE would not have succeeded in effectively taking action to fulfill its commitment to the State.

Today, the Group must sustain its action until 2038. To do this, P.-Y. Maestracci will pursue its mission within the framework of a thesis and will thus maintain the link between industrial operators, biologists and administrations. The commitment to the protection of the environment imposed by the State on manufacturers will lead them to systematically rely on experts like Denis Leca, capable of making two disciplines work together.

Storengy, forerunner of the Group's commitment in terms of biodiversity for many years, has been able to anticipate current needs by deploying within it an interdisciplinary specialty, making it possible to understand and respond to these new strong environmental constraints.

Guy Mogenot concludes: “It is absolutely fascinating, but in the 30 years that I have been working on industrial projects, I have never encountered this kind of constraint over such a long period of time. These constraints have a cost, which must be anticipated. It would seem logical to me that this support service or these skills be more developed and deployed in the Group as a cross-functional support function in its own right”.
