Wärtsilä will provide grid balancing services and reserve power to Scotland’s Shetland Islands with the supply of its energy storage system. The system is being supplied to Scottish and Southern Electricity Networks (SSEN) Distribution.
The system will deliver 8 MW/6 MWh of power when operational. Wärtsilä will support the installation with a ten-year service agreement, which includes maintenance for the software and hardware system components, as well as 24/7 remote support and management.
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. The solution will also facilitate the integration of wind turbine-generated electricity into the grid.
The project is being delivered by Wärtsilä under a full engineering, procurement, and construction contract. The system includes the company’s GridSolv Max product, a standardised energy storage solution that provides modular storage for the core hardware assets of the system, including batteries, a safety and fire system, and inverters, alongside the energy management platform GEMS. The software can integrate multiple generation sources seamlessly. The system is expected to be delivered by mid-summer 2021 and become fully operational in September.
