Approximately half of Gotlands electricity supply is generated by renewable sources located on the island. The challenge for Gotland is to handle this large share of variable renewable energy production. In good, normal, conditions this causes no problems but in the event of weather related operational disturbances Gotlands DSO needs to be able to remain control of the balance between production and consumption.
In this regional setting the issue is not limited to the need for flexibility and other system services. The demo will also have to take into regard the subject of power quality and security of supply. To ensure that solutions are well adapted to local conditions meetings have been held with consumers and additional analyses of context specific needs will be necessary.
