The combined entity brings together complementary strengths in battery storage development, gas peaking operations, and energy management, positioning it as a scalable platform to support the UK’s energy transition. With a combined pipeline exceeding 1.8GW of battery storage capacity and existing operational assets, Supernova Power aims to enhance grid stability and enable greater integration of renewable energy sources. InfraVia holds a majority stake in the new platform, while existing management teams retain minority ownership, ensuring continuity and expertise. The transaction reflects strong investor confidence in the growing role of flexible power solutions in the UK energy market.

(PRESS RELEASE) PARIS, 2-Apr-2026 — /EuropaWire/ — InfraVia Capital Partners has announced the formation of Supernova Power, a new UK-focused flexible energy platform created through the acquisition and integration of Mercia Power Response and Balance Power Projects. The transaction combines two complementary businesses into a single, scaled entity aimed at supporting the UK’s evolving energy system and accelerating the transition toward renewable energy.

InfraVia has taken a majority stake in both companies, bringing them together under the Supernova Power platform. Foresight Group, which has been the majority shareholder of Mercia Power Response since 2015, exits its leading position as part of the transaction.

Mercia Power Response has established itself as a key player in providing flexible power services to the UK grid, with expertise in the development, construction, and operation of gas peaking plants and battery energy storage systems. The company currently operates 262MW of gas peaking and battery storage capacity, alongside a development pipeline exceeding 400MW.

Balance Power complements this capability as a specialist developer of battery storage projects, having delivered 39 projects across multiple energy technologies. The company currently maintains a development pipeline of more than 1.4GW of battery storage capacity across the UK.

The newly formed Supernova Power platform will integrate development, construction, operations, energy management, and financing capabilities into a unified structure. This approach is expected to accelerate the deployment of battery storage assets, support further acquisitions in flexible power technologies, and enhance the reliability of the UK energy system.

The investment aligns with InfraVia’s broader strategy of supporting the energy transition by enabling the growth of renewable energy infrastructure. Supernova Power is positioned to address the challenges associated with intermittent renewable generation, particularly from offshore wind, by balancing supply and demand and providing backup capacity during periods of low generation.

InfraVia will retain a majority equity position in Supernova Power, while the management teams of both Mercia Power Response and Balance Power will hold minority stakes, ensuring continuity of expertise and operational leadership.

Graham White highlighted the importance of the partnership, noting that the combination of Balance Power’s development expertise, Mercia’s operational capabilities, and InfraVia’s financial strength creates a strong platform for growth in the UK battery energy storage market.

Ed Wilson reflected on Foresight’s decade-long involvement with Mercia, describing the transaction as a natural progression that enables further scaling and continued delivery of flexibility to the UK energy system.

Phil Thompson described the merger as a significant milestone, emphasizing the opportunity to accelerate growth and contribute more substantially to the energy transition through collaboration with InfraVia and Mercia.

Aymar de Tracy pointed to the UK’s mature energy market as a key driver for investment, highlighting the critical role of battery storage and gas peaking assets in maintaining grid stability and supporting long-term renewable energy integration.

InfraVia was advised on the transaction by Macquarie Capital and Ashurst, while Balance Power received advisory support from EY and Burges Salmon. Mercia Power Response and its management were advised by EY, Osborne Clarke, and Squire Patton Boggs.
