The solar thermal plant of Verdun will supply 8 GWh of decarbonized heat for the Lacto Serum factory nearby. With an area close to 15,000 m2, it became the largest solar thermal installation for industrial process heat in Europe, exceeding Issoudun’s plant, commissioned in 2021 by Savosolar, with a few hundreds m2.
This plant is the property of Newheat and Savosolar has been chosen to realize the solar thermal field as a turnkey project.
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.
As a general contractor, Savosolar built a solar thermal system on behalf of Fernwärme Ettenheim GmbH for the largest possible solar feed-in into the existing district heating network. 112 pieces Savo 15 SG-M large collectors generate fuel-free healthy heat, which is temporarily stored in two 100 m³ buffer storage tanks.
This also allows the operating hours of the CHP and the biomass boiler to be optimized. The scope of delivery included the fence and video surveillance system, as well as the creation of a meager meadow to enrich local biodiversity.
The construction work was temporarily interrupted due to the COVID19 restrictions. All system hydraulics were completely housed in a container. The keys were handed over in October 2020.
A PV system still to be built on the east side will generate the electricity for the pumps in the future.

A new forerunner project on the large scale solar thermal market in which Savosolar has been involved: The first solar thermal field with double glasses collectors on trackers. This innovation has been done to optimize the annual solar production with a limited available area. This new solar thermal plant is a property of newHeat and will delivered heat the network of the city of Pons, which is managed by Dalkia.
Savosolar supply on this project consist in the complete solar field field as a turnkey solution, it means, the design, the supply and the installation of the solar collectors and its trackers, as well as the piping, until the solar station. It represents 112 Savo 15 DG-M collectors, which will reduce of 210 tons per year the CO2 emissions for the city’s heat needs.
