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.
Savosolar was happy to sign its so far largest delivery contract with Grenaa Varmeværk in 2018. Savosolar’s highly efficient Savo 15 premium collectors are installed right next to an existing solar collector field which had been commissioned in 2014.
In this turn-key project Savosolar acts as the main contractor enlarging the solar fraction of the district heating network. Its operator, Grenaa Varmeværk, is producing about 146,000 MWh of heat per year. By using solar thermal it has managed to keep their customers´ heat price among the lowest in the whole of Denmark.
The new solar field with Savosolar collectors will increase the overall solar yield and ensure lowest energy production costs also in the future.
Savosolar delivered -once again- the largest solar thermal installation in Finland. This system is located way North in Tupos, Liminka – less than 200 km from the Arctic Circle.
The heating load of Tupos district heating is usually covered by wood pellets. Yet during summer time, the load is often so low, that the substantial wood pellet burner cannot be properly used and an oil burner got used, instead. The special challenge here has been to design a very efficient solar thermal system that could replace the oil consumption in summer to run the district heating network almost completely fossil-free.
Savosolar has been selected as general contractor to build the largest solar thermal system in Finland to date, on behalf of Suur-Savon Sähkö Oy for its district heating network in Puumala, which supplies households with healthy heating. In this hybrid installation the solar thermal system is producing both, high-temperature heat to district heating supply pipe and also low-temperature heat to improve heat pump plant COP.
