Wartsilato Offer Grid Balancing and Backup Electricity to Scotland's Shetland Islands

Wärtsilä will facilitate installing a ten-year service arrangement, which covers servicing of software and hardware system parts, and 24/7 remote support and management.

FREMONT, CA: The Wärtsilä Technology Group will provide grid balancing and backup electricity to Scotland’s Shetland Islands by supplying its integrated energy storage system. The machine is being supplied to Scottish and Southern Electricity Networks (SSEN) Distribution, which is part of SSE plc’s managed sector, one of the biggest utilities in the United Kingdom. The machine can produce 8 MW/6 MWh of electricity when it is operational. Wärtsilä will facilitate installing a ten-year service arrangement, which covers servicing of software and hardware system parts, and 24/7 remote support and management. The order was booked in December by Wärtsilä.

“As the electricity distribution network operator responsible for ensuring homes and businesses in Shetland receive a safe, secure and reliable supply of electricity, we’re investing in Lerwick Power Station to support full duty operations of the station until Shetland is connected to the GB electricity system. A reliable supply of electricity is essential to the local community and the North Sea oil companies operating out of Shetland, which is 200 kilometres from the northern tip of Scotland. The Wärtsilä energy storage system will enhance the islands’ security of supply, while at the same time lowering our carbon footprint,” said Darren Hitchin, Embedded Generation Manager, Lerwick Power Station.

The energy storage facility will be constructed at the Lerwick Power Station, owned by SSEN in Lerwick, the island’s capital. The power station is the chief generator for the local grid. The Wärtsilä energy storage solution would have spinning backup space, thus encouraging the further incorporation of wind power into the system. The energy supply will match the grid and save on the rotating reserve, aiming to save electricity and minimize CO2 emissions. The approach would also promote the incorporation of wind turbine-generated power into the grid, thereby adding more flexibility to the entire energy sector.

“Wärtsilä and SSEN maintain a long-lasting business relationship over the past two decades. We are very pleased to continue this cooperation by deploying our advanced energy storage system at Lerwick Power Station, which makes us part of Shetland Islands’ energy system. The GridSolv Max energy storage solution will support the power station’s spinning reserve functionality and can provide black start backup,” commented Bent Iversen, Senior Business Development Manager, Wärtsilä Energy.
