District heating

Voreppe

Veolia, a global corporation with focus on transport, waste, water and energy built and operate a new district heating network for the city of Voreppe, France.

For this solar installation, the space available for collectors was limited to a structure in midair between two buildings. Having a high solar yield was important criteria. Consequently, Veolia chose the well-designed Savosolar solution and its Savo 15 DG flat plate collectors being the most efficient in the market.

This installation in Voreppe was Savosolar’s first turn-key delivery for district heating in France. It raised interest among the district heating sector showing the potential of solar thermal as a clean heat production.

Mikkeli city, the home of Savosolar received the “Inspiring Solution Award” in 2018 Celsius City Summit for the Ristiina Village project. It is a green district heating energy concept with a clever combination of solar thermal and wood chips.

Savosolar was involved in this award winning project by delivering turn-key solar district heating installation to the Ristiina district heating plant.

Issoudun

With a size over 13,000 m2, this system is the second largest solar heating system in France and the second largest solar thermal system for industrial process heating in Europe.  Savosolar has delivered the largest part of the whole solar thermal plant including the solar collector field, civil work, piping and design and delivery of heat exchange station.

Kyotherm and its affiliate Kyotherm Solar are investment companies which specialize in the third-party financing of renewable heat and energy efficiency projects. Kyotherm Solar is selling heat from this system to a malt drying factory, which is operated by Malteries Franco-Suisses.

Cadaujac

This solar district heating system of 941 m2 in Cadaujac is an innovative and eco-friendly project, first of this type in France, develop by our customer AbSolar. The solar production is linked to a geothermal seasonal storage which lead this new neighbourhood to received 100% of renewable heat for their need in heating and hot water.

Savosolar has been responsible of the main part of the solar plant as part of an EPC contract, including the design and then the supply and installation of the solar field, the piping and the solar station with its automation system, as a turnkey solution. The 510 MWh of annual solar production allow to avoid around 100 tons of CO2 emission for such a heating need. With this project, Savosolar maintain is leading position on the French market in the supply of turnkey solar thermal plant for district heating.

This disruptive technology develops and handle by AbSolar is a forerunner project showing the possibility to reduce significantly our carbon footprint for the daily needs of heat and should help us to fight climate changes, while ensuring a mainly fixed cost of energy over 20 years for the inhabitants of this kind of residential district.
