InfraVia Acquires Majority Stakes in Mercia Power Response and Balance Power Projects, Merging Them Into Supernova Power

Why It Matters

The merger creates the UK’s largest flexible generation platform, accelerating storage deployment essential for grid stability and the nation’s net‑zero transition. It signals strong private‑capital confidence in the UK’s mature energy market.

Key Takeaways

• Supernova targets >2 GW capacity by 2035.
• Merges Mercia Power Response and Balance Power Projects.
• Portfolio includes 262 MW gas peakers and battery sites.
• Pipeline holds over 1.4 GW battery storage projects.
• InfraVia leads investment, boosting UK flexible generation.

Pulse Analysis

The UK’s power grid is at a pivotal juncture, with renewable output set to dominate generation mixes. Flexible resources such as battery energy storage systems (BESS) and fast‑response gas peakers are critical to smoothing supply‑demand mismatches and preventing curtailment. By consolidating two seasoned operators, Supernova Power positions itself to fill this flexibility gap, leveraging existing assets while scaling new projects to meet the anticipated surge in intermittent wind and solar output.

Supernova’s strategic advantage lies in its end‑to‑end capabilities—from site acquisition and permitting to construction, operations, and financing. The combined pipeline of more than 1.4 GW of battery storage, alongside a 262 MW portfolio of gas‑peaking units, gives the platform immediate market presence and a robust revenue base. InfraVia’s majority stake brings deep capital resources and a disciplined investment framework, enabling rapid deployment and potentially lower financing costs for future projects.

For investors and policymakers, Supernova’s launch underscores the growing appetite for private‑capital‑driven solutions in the UK’s energy transition. Accelerated storage rollout will enhance grid resilience, support higher renewable penetration, and create new revenue streams through ancillary services. As the UK targets net‑zero by 2050, platforms that can deliver gigawatt‑scale flexibility on a tight timeline will become indispensable, shaping the next wave of infrastructure investment and regulatory design.

Deal Summary

InfraVia Capital Partners has acquired a majority stake in UK energy firms Mercia Power Response and Balance Power Projects, merging the two to launch the new flexible power platform Supernova Power. The platform aims to deliver over 2GW of battery storage capacity by 2035, accelerating the buildout of flexible generation assets across the UK.
