SSE + Wärtsilä

A 50 MW / 100 MWh energy storage system helping the UK to decarbonise

Wärtsilä’s partnership with low carbon energy company SSE, one of the UK’s largest utilities, marks an important step in the UK’s path towards net zero. To help scale renewable energy capacity, Wärtsilä is delivering a 50 MW / 100 MWh energy storage system to SSE in Salisbury, Wiltshire. The system is the first to be directly connected to the transmission network by SSE and supports access to clean, reliable energy by balancing the intermittency of renewables.

The Salisbury energy storage system will provide grid services such as wholesale market trading, which will help balance renewable energy generation throughout the day. The facility will utilise Wärtsilä’s GridSolv Quantum, a fully integrated, modular, and compact energy storage system, as well as Wärtsilä’s sophisticated energy management software, the GEMS Digital Energy Platform.

This is what we are achieving

50 MW

and 100 MWh of energy storage capacity 

258 MW

in total - in the UK, utility-scale energy storage projects

Battery storage has a key role to play in helping the UK to decarbonise by ensuring we make the most of the increasing levels of renewable energy coming onto the grid. SSE is investing £24bn over this decade (circa £7m a day) in low carbon infrastructure of this kind and we are delighted to be working alongside Wärtsilä to provide the balancing and flexibility services we need to help the UK get to net zero
