Kyotherm grows in Scotland, with a portfolio of biomass boilers that will produce 24 GWh/year

Kyotherm acquired between October and December 2017 a portfolio of 6 biomass boilers (wood chips) with a total capacity of 5 MW, and signed an Engineering, Procurement and Construction (EPC) contract for a 7th 1 MW biomass boiler. These installations, all located in Scotland, will provide renewable heat to hotel resorts, spas, nurseries, commercial spaces, and industrial sites. The estimated annual renewable heat production is 24 GWh/year, thus reducing greenhouse gas emissions by 5,200 tons per year and creating 4 permanent local jobs.

Kyotherm signs an Energy Performance Contract of 15 GWh/year for an industrial site

In October 2017, Kyotherm and its partner Schneider Electric signed a contract to install variable speed drives at an iron and steel plant located in Fos-sur-Mer, France. The drives will regulate the power consumption of a set of electric motors (for pumping, ventilation, dust removal) which have a total power of 11 MW. The estimated energy savings (approximately 15 GWh/year) will finance the initial investment. They will also, from the industrialist’s point of view, generate cost savings from the first year on, through a “deconsolidating” financing arrangement.

The energy savings are equivalent to the production of a 12 MW photovoltaic installation, or that of an 8 MW wind farm, with the advantages of a small land incidence (a few m3) and of a stable rate in terms of power savings.

Kyotherm, ArcelorMittal and Schneider Electric launch a waste heat recovery project in Saint-Chély-d’Apcher (France)



Three participants in Saint-Chély project 

ArcelorMittal, Kyotherm, Schneider Electric and the city of Saint-Chély-d’Apcher (South of France) launch a waste heat recovery project

The waste heat recovered from the ArcelorMittal industrial site will notably supply part of the city’s housing


Saint-Chély-d’Apcher, May 30, 2017 – ArcelorMittal, Kyotherm, Schneider Electric and the city of Saint-Chély-d’Apcher (South of France) disclose the launch of a waste heat recovery project that will allow to save 4,000 tons of CO2 emissions per year, which is equivalent to taking 2,000 new vehicules off the roads. This heat is generated by the industrial process and would be lost otherwise. The project is due to be commissioned in the first half of 2018. The investment amounts to €5.6m, it is borne by Kyotherm and benefits from subsidies from the ADEME (French national Agency for Environment and Energy Management) and from the Occitanie Region.


The waste heat recovery project

The project involves recovering heat at a temperature of 1,000°C lost by the ArcelorMittal steel annealing oven, and reusing it for the city district heating network and for the plant needs (process heat and space heating). Heat exchangers, pipes and automation devices will be provided by Schneider Electric to collect up to 4.8 MW of heat. This energy will then be distributed by a 1.2 km long network and will provide for the needs of the equivalent of 1,150 housing units.

The existing oil-fired boilers will also be replaced by a 4 MW high-efficiency natural gas heating plant. In total, the project will allow to improve the carbon footprint of a 17 GWh yearly heat consumption, by reducing the CO2 emissions by 4,000 tons per year.


Combining three complementary competences in one project

  • The operator of the industrial site: ArcelorMittal has played an important part in the initiation of this project, which illustrates its efforts and actions towards reducing its carbon footprint all the while renforcing the competitivity of its plant, the largest local industrial employer.
  • The specialist in energy management and automation: Schneider Electric, a longstanding partner of the site, is in charge of the engineering and construction of the installations, with a high added-value in terms of automation, for a smarter management of the supply and offtake of the network.
  • The energy-efficiency third-party investor: Kyotherm (via a dedicated subsidiary) has enabled this highly capitalistic project to see the light by supplying heat to ArcelorMittal on an off-balance-sheet basis at a competitive price.




Arnaud Susplugas, CEO of Kyotherm

“ The financing of this project by Kyotherm enables ArcelorMittal to recover and use its waste energy all the while keeping its financing capabilities for its industrial core business. Thanks to its long-term vision and to a good integration of the technical considerations, Kyotherm is able to provide heat to ArcelorMittal at a competitive price. This business case which favours use over ownership is particularly relevant for waste heat recovery projects. Indeed, such projects enable considerable savings in terms of operating costs, but they require a significant initial investment. In this context, Kyotherm is a natural financial partner for project developers and heat consumers, and we believe that this type of operation will develop in the years to come.”


Philippe Chapus, project manager, ArcelorMittal

“Energy efficiency has always been one of the priorities of the ArcelorMittal site in Saint-Chély-d’Apcher, which is dedicated to the production of so-called “electrical” steels, which are used in high efficiency electric motors and generators. Waste energy (from industrial furnaces for instance) is captured from our new continuous annealing line. The entire local team promoted and drove this project. It would neither have been possible without a strong involvement of the management of ArcelorMittal and of local authorities, nor without the innovative technical and economic solution brought by Kyotherm and Schneider Electric. It will reduce the plant’s environmental footprint by cutting its energy consumption for the transformation of steel by more than 10%, and it demonstrates ArcelorMittal’s willingness to adapt to its natural environment.


Fabien Chêne, commercial director, Schneider Electric

“As a global energy management specialist, Schneider Electric offers high added value solutions and services to help its clients define their sustainable development strategy and implement their energy efficiency program. The Saint-Chély-d’Apcher heat recovery project fully corresponds to Schneider Electric’s energy efficiency strategy, from the design to the realisation of virtuous facilities in terms of reduction of carbon footprint. This project is the first step towards a comprehensive energy efficiency program that we wish to develop with ArcelorMittal.”


Pierre Lafont, mayor of the city of Saint-Chély-d’Apcher

“The city of Saint-Chély-d’Apcher and its history are closely linked with the one of the plant, which has left its mark on the local economic and social life for a century now. The joint history of the plant and the city has taken an important step on September 20, 2013 when ArcelorMittal inaugurated its high value-added electrical steel production line, making Saint-Chély-d’Apcher the world capital for electrical steel production for power generation.

Strengthened by its history, Saint-Chély-d’Apcher is also looking to the future, concerned about the well-being of the coming generations and about the preservation of its amazing heritage. We have therefore already taken our first step into the energy transition by developping a biomass-fueled district heating network. The connection of the plant and the recovery of its waste energy are therefore welcomed as a new opportunity to work towards towards the construction of a sustainable city, and to write a new page of our commun history.”

Commissioning of two district heating networks (biomass and geothermal) in France

Two Kyotherm subsidiaries have begun supplying heat to their clients at the beginning of 2017, through two renewable energy district heating networks.


Start of the pre-heating on behalf of the Villages Nature theme park, located in Marne la Vallée

Construction works on the “Villages Nature” tourism park are progressing towards the inauguration planned for the Summer 2017. Most buildings have already been completed, and Société Géothermale de Val d’Europe, the Kyotherm subsidiary in charge of the heating of the park, has begun providing those buildings with heat in January.

The 1850m deep geothermal doublet fully meets expectations and needs, with a 20-MW available heat power. In the future, it will also be connected to the Disneyland Paris parks, through the Val d’Europe territorial community. The Marne la Vallée geothermal district heating network will lead to a reduction of CO2 emissions of 15.000 tons per year.

The design and construction of the geothermal plant and of the 26-km district heating network have been conducted by Engie Réseaux, a leading company on the French energy services market, particularly when it comes to renewable heating networks.


Commissioning of the biomass heating network of the Ecole des Roches, in Verneuil-sur-Avre

The 13 buildings of the Ecole des Roches, as well as its swimming pool, are now heated thanks to a biomass heat plant and its distribution network. This has been the case since January 20, 2017, when these facilities were commissioned.

Through its 85%-owned dedicated subsidiary (alongside with AgroNergy), Kyotherm has funded this project and will provide, instead of fuel oil which was used before, renewable heat to this school campus for a 15-year period, thus avoiding 850 tons of CO2 emissions per year.

The design and construction of the boiler-house and of the 2-MW heating network were conducted by AgroNergy, a company specialized in turnkey constructing and operating of firewood and biomass heat plants.

Kyotherm will attend the Journées de la Géothermie on September 20-22th, 2016 (booth number 21) in Strasbourg

Kyotherm will attend the Journées de la Géothermie on September 20-22th, 2016 (booth number 21) in Strasbourg.

Success of the drilling of the geothermal wells in Marne la Vallée

The drilling of the first geothermal well for project Villages Nature in Marne la Vallée has been completed in July 2015. The Dogger, a reservoir of hot and abundant water, has been reached at a depth ranging between -1,827 meters and -1,847 meters. A temperature of 80,7°C has been measured in this reservoir which displays the expected physical characteristics (notably a high porosity at production level). The  drilling of the second well has been completed in September 2015 and proved that the exepected flow rates can be reached with limited pumping power.

This geothermal drilling was financed by Société Géothermale de Val d’Europe, a 34% subsidiary of Kyotherm, which it assists operationally. The EPC contractor of the drilling is GDF Suez Energie Services (Engie).


Drilling machine on the Villages Nature site

Kyotherm considers that a geothermal doublet in that region will be able to produce for more than a century a carbon-free energy at a low marginal cost,  supplying more than 5,000 Equivalent Residential Units at the same time and providing a real environmental, economic and social benefit to the region.

Press release


Paris, February 12th – Kyotherm, Omnes Capital, Cofely Réseaux and Storengy team up for the design, construction, financing and operation of the geothermal heating network of the future eco-touristic destination Villages Nature.

By teaming up with robust financial partners and renowned experts in the field of geothermal energy, Villages Nature will benefit from a renewable energy that stems from a local source in the undergrounds of Marne-la-Vallée: an energy solution that is ecological, innovative as well as consistent with the ambitions of the Villages Nature project in terms of sustainable territorial development.


A renowned group of experts with complementary know-hows

The four partners have created a dedicated company – Société Géothermale de Val d’Europe – in order to build and operate the geothermal heating network under a 25-years concession agreement.

Main investors are Omnes Capital and Kyotherm, with Kyotherm managing the dedicated company. Both actors have provided equity to the project, and are supported by long-term investors that are sensitive to the challenges of sustainable development and of the energy transition. The total cost for building the heating network and the geothermal plant amounts to €41.3m.

Cofely Réseaux and Storengy, both GDF Suez subsidiaries, are minority shareholders in the company. Cofely Réseaux is in charge of the design, the construction and the operation of the geothermal doublet and the heating network. Cofely Réseaux relies for that on Storengy’s expertise in the field of underground operations.


A 100% renewable energy solution

The four partners will provide Villages Nature with a 100% local and renewable energy solution that meets the ambition of this unique eco-touristic destination. The supply of geothermal energy to Villages Nature consists in extracting water at 76 degrees from a 1,25 miles deep aquifer cavity. Brought up by the production well, the geothermal heat will be distributed according to a precise distribution network designed for a sustainable use that limits thermal losses. The geothermal heat will first cover the heating and hot sanitary water demand from all flats, cottages as well as entertainment installations. The residual heat, which temperature will then have reduced to approx. 30 degrees, will supply the Aqualagon, a 9 000 m² covered water park, as well as its 2 500 m² external lagoon, and will eventually be restituted to its natural environment through the injection well.

The use of geothermal energy, a clean energy that does not emit any greenhouse gases, will allow to avoid the release of 9 000 tons of CO2 per year in the atmosphere.


Commissioning of the heating network and geothermal plant in 2016

  • July 2014 – Summer 2016: construction phase
    • Preparation of the drilling site
    • Drilling on the 1 800 meter deep Dogger aquifer
    • Construction of the 18km heating network
    • Construction of the building for the geothermal plant
  • Summer 2016: commissioning of the 18km heating network and of the 13.5 MW geothermal plant


Arnaud Susplugas, CEO of Kyotherm and of Société Géothermale de Val d’Europe:

“This geothermal heating network project in Marne-la-Vallée is the proof that producing renewable energy can be economically competitive. The cost of capital usually represents over 50% of the global cost of a renewable MWh. Resorting to project financing for these energy infrastructures has allowed to obtain a very attractive cost of capital. In the end, the price of the renewable MWh is competitive compared to fossil energies, which corresponds to Kyotherm’s ambition and vision.”




Kyotherm is an investor specialized in the financing and management of renewable heat or energy savings projects. Its team has an extensive expertise in geothermal energy, having notably financed four heat production projects relying on geothermal energy in partnership with energy service companies. Kyotherm aims to be a shareholder having an active role in the management of the project throughout the all duration of the project.
