belgian greenhouseThe installation marked the worlds first HSK78G gas generator installed in a greenhouse environment. The greenhouse which has been harvesting a range of crops for over 40 years, has grown to become one of Belgium’s largest exporters with premises totalling 40,000m2. The HSK78G supplies the site with 2MW of power, 44.2% electrical efficiency and a high tolerance towards variable natural gas fuel qualities with resistance to external environmental factors.

Flexible Energy

The installation provides the greenhouse with thermal and electrical energy as well as CO2. Varegro can use this energy source to flexibly meet energy needs, the electricity can be used for lighting, the heat produced for heating and the exhaust gasses cleaned and used for CO2 fertilization. In addition, the generators heat buffer allows Varegro to influence the variable energy market and support the grid network. The electricity is sold back to the grid in a flexible manner which offers greater fuel savings for Varegro.
