InfraVia has launched Supernova Power by acquiring majority stakes in Mercia Power Response and Balance Power Projects and merging them into one UK-focused flexible power platform. The combined business starts with 262 MW of operating gas peaking and battery assets from Mercia, more than 400 MW of Mercia battery storage development, and 1.4 GW of battery storage pipeline from Balance. That gives Supernova Power an immediate operating base plus a multi-gigawatt development runway.

The real signal is not just scale. It is integration. UK buyers are moving beyond single-asset battery acquisitions and are backing platforms that combine development, construction, operations, energy management, and financing under one roof. That model reduces execution risk and speeds up build-out in a market where grid flexibility is becoming as valuable as generation itself.

This deal fits the broader UK and European M&A pattern. Enerdatics noted that Europe’s BESS M&A rose sharply in Q3 2025, with the UK, Germany, and Italy accounting for over 60% of traded capacity, while the UK remained a leading market for late-stage and shovel-ready storage acquisitions.  Supernova goes a step further by pairing operating flexible gas peakers with a 1.8+ GW battery-led platform, creating a more bankable route to scale.
