The technology group Wärtsilä will provide grid balancing services and reserve power to Scotland’s Shetland Islands with the supply of its advanced energy storage system. The system is being supplied to Scottish and Southern Electricity Networks (SSEN) Distribution, which belongs to the regulated businesses of SSE plc. The system will deliver 8 MW/6 MWh of power when operational. Wärtsilä will support the installation with a 10-year service agreement, which includes maintenance for the software and hardware system components, as well as 24/7 remote support and management. The order was booked by Wärtsilä in December.
The energy storage system will be installed at the Lerwick Power Station, operated by SSEN in Lerwick, the Islands’ capital. The power station is the main generator for the local grid and the Wärtsilä energy storage solution will provide spinning reserve capacity, while also facilitating further integration of wind power into the system.
