District heating

Guangzhou

Savosolar has been selected to deliver a tracker mounted solar thermal plant for the district heating of Nansha, Guanghzou, China. The system is combined with a geothermal seasonal storage and a chiller (not in Savosolar’s scope of supply) which allow the owner to deliver healthy energy, both heating and cooling, to its customers.

FORS A/S

FORS A/S is an energy company owned by three Danish municipalities. Their district heating plant in Jyderup has about 900 customers and produces about 5000 MWh solar thermal energy per year. For the rest of its energy production, the plant uses two gas boilers with 7 MW thermal capacity and two gas engines with 6 MW electrical capacity.

In Jyderup, the collector field is a so-called hybrid field, with both single and double glazed collectors. The single glazed collectors are in the cold end of the collector rows and increase the low temperature as rapidly as possible, while the double glazed collectors are located in the warm side of the collector rows where it is more important to reduce the heat losses. The collector field also has double stanchions which allows for two collector rows to connect to one and the same pipe and thereby save costs and thermal losses.

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.

Bad Rappenau

UNDER CONSTRUCTION

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

Summa Energy 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.
