Question to the Department for Energy Security & Net Zero:

To ask the Secretary of State for Energy Security and Net Zero, what proportion of firms operating battery cell capacity across British battery energy storage systems are Chinese- (a) owned and (b) financed.

The Department works very closely with industry and across government to manage foreign involvement in energy infrastructure. The largest grid-scale battery owners in GB are all UK-based companies - and battery operators include UK, European, Singaporean and US companies - though there has not been a detailed assessment of the ownership and finances of this sector. We continue to take a long-term, strategic and proportionate approach to managing relations with China and will co-operate where we can, and challenge where we must.
