The IT system Power Hub has helped the Faroe Islands save CO2 and reduce the number of power cuts.
The Power Hub system monitors the power grid and briefly switches off selected units when there is not sufficient renewable energy to supply the power grid.
Power Hub, which is a system developed by DONG Energy, helps make the most of the renewable energy sources and ensures a reliable power supply in a more environmentally friendly way. The system monitors the power grid and briefly switches off selected units when there is not sufficient renewable energy to supply the power grid.
As island communities get more and more renewable energy, their energy system becomes more vulnerable. Lack of cable connections to the mainland or to other islands may result in major power cuts when consumption is high and the wind power production is low. Therefore, many islands have to supplement their power supply with diesel generators, which are both expensive and polluting, in order to be able to stabilise the power supply if the renewable energy supply is not sufficient. This is a well-known problem in the Faroe Islands. The group of islands has one of the highest shares of renewable energy and with Power Hub, DONG Energy has helped stabilise the supply since 2013.
In the Faroe Islands, a large fish farm and a cold store have been connected to Power Hub. In less than a second, refrigerating and freezing compressors and a heat pump can be disconnected from the power grid during short intervals without any problems. The company saves money due to lower consumption and the power system avoids overload and power cuts.
