The Wishaw Battery Energy Storage System is a 50 MW / 100 MWh grid-scale battery in Wishaw, North Lanarkshire, Scotland, developed and operated by Zenobē. It was the first battery in Scotland to connect directly to the transmission network and was commissioned as part of efforts to strengthen security of supply and support high levels of renewable generation on the grid. Wishaw formed the first operational asset in Zenobē’s planned portfolio of large-scale storage projects in Scotland.

The facility was built to help manage transmission constraints caused by the rapid uptake of renewable generation, particularly wind, and to reduce costs for consumers by increasing the time wind farms can generate power. As part of National Grid ESO’s Constraints Management pathfinder project, Wishaw provides flexibility services and helps reduce renewable curtailment, storing enough energy to power over 500,000 homes for two hours and passing on an estimated £41 million in savings to consumers over 15 years.

Zenobē delivered the project with partners including Fluence, Centrica, H&MV, and Santander UK, and has framed Wishaw as a key milestone in its investment of roughly £750 million in Scottish energy storage capacity. The site’s operation contributes to broader efforts to integrate more renewable energy and enhance grid flexibility as Scotland and the UK pursue decarbonisation goals.
