For years, it was the largest solar heating plant in the world, and still ranks among the largest. The solar panels cover up to 50% of the annual heat production. The latest extension included a new 75,000 m3 water reservoir for heat storage. The water is heated by the sun through the solar panels during the summer and stored for use in the winter.
