District Heating Graz Liebenau
On the roof of the skating hall of the Stadium in Graz Liebenau, a solar thermal system with 1407 m² collector surface was built on
The utility Stadtwerke Radolfzell was interested in solar thermal for its heat generation portfolio.
Liggeringen was the first solar thermal plant for the company. They want to gain experience with the technology in order to decide about more solar plants in the future. Liggeringen was the perfect opportunity for solar thermal, as it runs mainly on biomass in winter and solar thermal is a perfect match for summer.
The solution with 3 large thermal buffer storages of 240 m³ in total allows solar only summer time operation as the buffer is sufficient for several days with low irradiation.
SOLID gave support for higher-level controls implementation, not only for solar thermal. SOLID also supports the customer for his long term strategy in use of renewables.
