The technology group Wärtsilä will partner with low carbon energy company SSE to deliver a 50 MW energy storage system in Salisbury in Wiltshire. The battery will be the first connected directly to the transmission network by SSE’s new solar and battery division and will support access to clean, reliable energy by balancing the intermittency of renewables. The order was booked to Wärtsilä’s order intake in April 2022 and the system is expected to become operational in September 2023.The project will include Wärtsilä’s GridSolv Quantum, a fully integrated, modular and compact energy storage system, as well as the GEMS Digital Energy Platform, Wärtsilä’s sophisticated energy management software.Wärtsilä is currently installing similar sized energy storage systems across the UK, demonstrating their commitment to supporting more renewable energy and helping the UK reach its net zero targets. Energy storage capacity will need to dramatically rise to 18 GW by 2035 to manage the transition, according to modelling from Wärtsilä.The energy storage system will support the UK’s national grid with reliable services such as wholesale market trading, crucial for balancing renewable energy generation throughout the day. The UK’s energy storage pipeline has doubled within the past year, demonstrating the growing importance of energy flexibility as the UK scales up its renewable capacity. By supporting SSE to scale up its significant ambition in energy storage systems, Wärtsilä is enabling more British energy consumers to access secure renewable energy, reducing costs while lowering carbon emissions.
