Wärtsilä To Deliver 68 MW Energy Storage System In Shetland - CleanTechnica

Wärtsilä is set to deliver a 68 MW, 2-hour duration lithium iron phosphate (LFP) battery energy storage system (BESS) to Zenobē in Lerwick, Shetland, marking the first UK deployment of Wärtsilä’s Quantum2 technology. The system aims to enhance energy security and reduce emissions by providing critical infrastructure services, including grid backup and restoration if the interconnector to mainland Scotland fails. This will enable the diesel-fired Lerwick Power Station to shift into standby mode, reducing carbon emissions by an estimated 2.2 million tonnes over ten years. The battery system will not be directly paired with renewable generation but supports increased renewable integration by stabilizing the grid. The project incorporates advanced grid-forming inverters, which can independently maintain grid voltage and frequency, enabling more resilient and renewable-friendly grid operation compared to traditional grid-following inverters. Wärtsilä’s GEMS Digital Energy Platform will manage the battery’s real-time performance, optimizing
