World’s biggest solar thermal system currently under construction in Austria

16. March 2016

Regional capital Graz creates a total collector area of 7,000 m2 in the near future

The world’s biggest solar thermal system with expansive heat storage capacity is being constructed in Graz.  It is designed to provide Graz district heating with a fifth of its total energy demand by 2019. The plant will generate more than 3.5 million kWh of heat per year using solar energy only. The system is capable of storing thermal energy and releasing it on demand. The total costs of the investment will be around EUR 200 million. Inspiration was derived from a visit to Vojens solar park in Denmark. The project called “Big Solar” was developed by Austrian Solid in collaboration with Danish experts and Energie Steiermark.
