District heating

Suur-Savon Sähkö

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.

Ystad Energi AB

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.

Etelä-Savon Energia

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.

Bad Rappenau

UNDER CONSTRUCTION

Bad Rappenau, Germany (largest flat plate collector plant in Germany)

Savosolar has been selected as general contractor to build a +20 MW solar thermal system on behalf of Bauer Holzenergie GmbH for its district heating network, which supplies households and an industrial process for drying fruits with healthy heating. Only about 1,800 pieces of Savo 16S large scale high performance flat plate collectors are sufficient to getting combined with an 8,000 m³ heat storage tank and
provide carbon free heat for the needs of all connected consumers.
Additionally, a PV system will be built on site to generate the electricity consumed by the solar pumps, thus
unburdening the local power grid.
