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.
The system will deliver 8 MW/6 MWh of power when operational.
Wärtsilä will support the installation with a 10-year service agreement.
The energy storage system will be installed at the Lerwick Power Station, operated by SSEN in Lerwick.
Darren Hitchin, embedded generation manager at Lerwick Power Station, said: “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.”
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 proprietary energy management platform GEMS.
