IN Brief:
- InfraVia has merged Mercia Power Response and Balance Power into a new UK platform called Supernova Power.
- The combined business starts with operating gas peaking and battery assets, battery development sites, and a multi-gigawatt storage pipeline.
- Supernova Power is being positioned as an integrated platform covering development, construction, operations, energy management, and financing.
InfraVia has merged Mercia Power Response and Balance Power into a new UK flexible power platform called Supernova Power, bringing together operating response assets, battery development sites, and a larger project pipeline under a single structure. The transaction gives the new platform a mixed base of operational capacity and longer-dated battery build-out.
Mercia Power Response enters the combination with a 262 MW portfolio of gas peaking and battery storage sites, alongside a development portfolio of more than 400 MW of battery storage. Balance Power adds more than 1.4 GW of battery storage pipeline and a project track record spanning 39 schemes across multiple energy technologies. The structure therefore combines near-term operating and construction capability with a much broader pipeline of storage-led projects.
InfraVia has said Supernova Power will span development, construction, operations, energy management, and financing, giving the platform the scope to move beyond a pure development model. That is significant in a market where battery projects increasingly depend on control, route-to-market, asset management, and financing as much as on connection and EPC delivery.
The deal also reflects a continuing shift in UK flexibility markets toward scaled platforms that combine build pipelines with operational capability. As battery deployment deepens and the grid leans further on fast-response assets, integrated portfolios are becoming more central to how capital is being deployed into storage and flexible generation.
