Ystad Arena is located in the southern Swedish city of Ystad, and is the home arena of Ystad IF HF which is one of the country’s top handball teams. On its roof, 36 collectors from Savosolar were mounted during spring 2017. The system is owned and maintained by the municipality owned energy company Ystad Energi AB, and feeds its district heating network with clean thermal energy. Ystad Energi AB is working towards the goal of becoming fossil fuel free by 2020 and currently produces ca. 160,000 MWh of thermal energy annually, of which 97-99% are based on bio-fuels.
As much as 89% of the thermal energy for the district heating network is produced by four wood chip burners between 3 and 10 MW capacity and the rest is produced from straw, rapeseed, gas and oil. Ystad Energi AB has ca. 1,850 customers, of which ca. 1,300 are single family homes.
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.
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.
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.
