A reliable electricity supply is essential to the local community living on the Shetland Islands, a subarctic archipelago in the Northern Isles of Scotland. The Lerwick Power Station is the main generator for the grid, with an obligation to deliver uninterrupted power to the island community.
The introduction of energy storage will enhance the islands’ security of supply and reduce operating hours on the diesel generators. Wärtsilä’s 8 MW / 6 MWh energy storage system and GEMS Digital Energy Platform are enabling an increased integration of existing renewable power into the power system, which will help lower CO2 emissions. A combination of flexibility solutions is setting the Scottish archipelago on a path towards a cleaner energy system.
