Background

ETC Solpark is one of Sweden’s largest solar parks, with a capacity of 400 kW. The solar park is owned by ETC El and is located in Katrineholm. In 2017, a decision was made to complement the solar park with a combined heat and power plant connected to a greenhouse for tomato cultivation. The facility includes two heat sources consisting of concentrating solar collectors and a biochar boiler. These heat sources are connected to an ORC system that produces electricity and hot water for the adjacent greenhouse. The plant also includes a thermal storage tank to balance energy production over the course of the day.
