Wind, tidal currents and swells provide France with a significant renewable energy potential, but to capture and convert these forces into electricity, manufacturers must design reliable, high-performance technologies to produce electricity at a competitive price. After several years of development and structuring, the national territory will soon have its first « industrial parks ».
Based on these experiences, how do industrialists and territories perceive the economic development of Marine Renewable Energies?

The building industry is the largest energy consumer. Therefore, the energy renovation of homes, the control of energy consumption in the tertiary sector and the optimization of agricultural and industrial equipment are key levers to achieve the carbon neutral objectives set at 2050.

20 mns presentations followed by questions-answers

Amandine Loti, TARANIS Network.

Space Workshop 1

Renewable energy projects run by citizens or communities are gaining momentum throughout France. Brittany was a pioneering territory, and the Taranis Network, which brings together Breton project promoters, invites you to discover how its companies work, how to create them and the values they carry. The example of the regional company Kerwatt, will illustrate the subject.

Sandra Tochon and François Nepveu, CEA TECH

Space Workshop 2

In France, heated greenhouses are mainly used to grow tomatoes and cucumbers. For these two crops, 560 ha of heated greenhouses are located in the Brittany and Pays de la Loire regions, more than 50% of the French park. Improving the environmental footprint of heated greenhouses and reducing the massive use of fossil fuels for their heating needs, above 400kWh / m² / year, are major issues. To meet this challenge, CEA Tech is seeking to target the sector’s new innovation needs by working on the energy and biochemical balance sheets of greenhouse production.

Space Workshop 1

Communities have an important role to play in the Energy Transition of territories. Energy management is one of the levers for achieving this transition. However, managing the energy of a housing stock that is as heterogeneous as the one of the communities is a real problem. The buildings are numerous and their typologies various (schools, administrative buildings, swimming pools, sports complexes, etc.), as many characteristics that should be mastered.
So, how to manage energy at the community level?

Erwan Le Pemp, Head of Saveol NE and Carbogreen purchase manager (Saveol energy purchase)

Space Workshop 2

Today, consumers expect products with a low environmental footprint. Savéol Energies Nouvelles is a circle of energy players gathered around Savéol, the leading Breton cooperative in tomatoes production in France. It is intended to support green market gardeners in the energy transition (wood energy, photovoltaics, energy efficiency, methanisation …) while the mobilization of public aid and funding is becoming scarce.

As part of the actions of their PCAET, the aerial mapping of the lighting of a territory makes it possible to draw up an inventory and to plan the actions aiming at reducing this pollution.

Grégoire Super, President of LIGER President, Mayor of Locminé l Marc Le Mercier, Manager LIGER, President of LIGER BioConcept.

Space Workshop 2

How can our organic waste become sustainable energy resources?
At Locminé in Morbihan, this question was clarified with the creation of a renewable energy center in 2011. The SEM LIGER produces 4 energies and 3 organic by-products by using a biomass boiler and an anaerobic digestion unit. This circular local economy is today a demonstrator of energy optimization reducing the carbon footprint of the territory. Grégoire SUPER, President of the SEM and Mayor of Locminé, will present the city’s involvement in the project. Marc LE MERCIER, General Manager at LIGER, will talk about the development of activities. Indeed, to duplicate the functional model of the SEM LIGER, SAS LIGER BioConcept  was created in 2018. Its objective? Design and support circular projects committed to a low carbon economy. To cooperate to progress, here is the motto of LBC!

Frederic Cosperec, Territorial Development Brittany Manager-EDF l Michel Henaff, Commercial Manager-CITEGESTION / CITELUM

Workshop 1

From the urban and rural territorial density to the management of the energy resource, from the climate challenge to the economic and societal challenge, the territories are confronted with the multiple challenges of the energy transition. Faced with the expectations of a more sustainable society, the concept of smart territory opens up a wide range of answers and solutions.
It is to support these emerging issues that EDF and its subsidiaries have developed responses around smart and connected territories. Dedicated to local authorities, social landlords and all economic actors as well as citizens, the EDF group’s solutions are part of a sustainable development strategy that is a great catalyst for accelerating energy transition.

Romain Coiffard, Wind Project Manager-WPD France l Antoine Monteillet, Offshore wind project manager-WPD France.

Workshop 2

While the Multiannual Energy Program should set ambitious targets for the development of renewable energies, their integration into the territories is proving to be a key success factor.
Engaged for almost 20 years, wpd strives to involve every player in the territory, and this, from the genesis of the project.
Wpd teams will present during this workshop, consultation tools put in place during the development of certain wind projects (land and sea), and how they have evolved to promote their acceptance and local integration.

Roger Le Goff-Mayor of FOUESNANT l Henri Le Gallais, president-ENAG l Laurent Meyer-ENTECH SE l Frédéric Mescoff and Eric Laurent-ENEDIS.

Workshop 1

The realization of a Smart Grid on the island of Saint Nicolas des Glénan island is the result of a community and industrial partnership. This partnership was born thanks to a strong will of the city of Fouesnant and thanks to the commitment of industrial partners of the territory.
The cooperation between ENAG, ENEDIS and ENTECH was one of the keys to the success of this project and to meeting deadlines. In the end, it is a very beautiful common experience that was conducted in the service of a magnificent project of local energy transition.
