Eurazeo has led a major equity financing round into terralayr, committing capital through its Eurazeo Transition Infrastructure Fund to accelerate the build-out of grid-scale battery storage and digital flexibility infrastructure across Germany.

The €192 million round includes an €80 million upsizing option and was completed alongside RIVE Private Investment and existing shareholders. The investment positions terralayr to expand one of Europe’s fastest-growing segments of the power market at a time when renewable penetration, electrification and industrial power demand are placing unprecedented pressure on grid stability.

Grid Flexibility Moves to the Centre of Germany’s Energy Transition

Germany’s power system is undergoing structural change. Rapid renewable deployment, rising electricity demand from data centres and heavy industry, and heightened energy security concerns are increasing the need for flexible capacity that can stabilise the grid and manage volatility.

Battery energy storage has emerged as a core solution to this challenge. Grid-scale storage enables excess renewable generation to be absorbed, frequency services to be delivered and power to be dispatched when supply-demand imbalances arise. As a result, the addressable market for flexibility and storage services is expected to expand sharply over the coming years.

Eurazeo’s investment reflects a growing investor consensus that flexibility infrastructure is becoming as critical to the energy transition as generation assets themselves.

terralayr’s Integrated Asset and Platform Model

Founded to address the fragmentation of Europe’s flexibility markets, terralayr develops, owns and operates grid-scale battery energy storage systems while simultaneously running a proprietary digital platform, LAYR.

The LAYR platform virtualises battery assets and provides route-to-market services not only for terralayr’s own portfolio but also for third-party storage operators. This integrated model allows flexibility to be aggregated, optimised and commercialised across multiple market segments, including balancing, ancillary services and wholesale power markets.

By combining physical infrastructure with a software-led marketplace, terralayr is positioning itself as a system-level enabler rather than a single-asset developer.

Capital to Accelerate Asset Build-Out and Platform Scaling

The newly raised capital will be deployed to accelerate the construction of grid-scale battery projects across Germany while scaling the LAYR platform in parallel. The strategy is designed to ensure that digital market access expands in step with physical capacity, reinforcing liquidity, utilisation rates and long-term asset economics.

According to Eurazeo, the investment supports continuity and sustainability in Germany’s power supply by strengthening the infrastructure required to manage intermittency and demand growth.

For terralayr, faster asset deployment is also critical to attracting utilities, flexibility traders and industrial users that require reliable, multi-gigawatt-scale flexibility solutions.

Eurazeo Closes Out Its Transition Infrastructure Fund

The transaction marks the ninth and final investment of the Eurazeo Transition Infrastructure Fund. The portfolio spans renewable generation, data centres, electric vehicle charging, waste management, water infrastructure and offshore services across Europe.

Eurazeo described terralayr as a natural fit for the fund’s mandate, given the company’s role in enabling the decarbonisation of power systems while reinforcing energy security and grid resilience.

Investor and Founder Perspectives

Melissa Cohen, Co-Head of Infrastructure at Eurazeo, said the firm views terralayr as well positioned to address a fundamental system need within the power sector, combining a growing asset base with a digital marketplace that underpins flexibility and stability.

Philipp Man, Co-Founder and Chief Executive of terralayr, said Eurazeo’s backing enables the company to accelerate the deployment of much-needed flexibility infrastructure in Germany, while strengthening the platform that connects asset owners, utilities and market participants.

Flexibility Infrastructure Becomes Strategic Asset Class

The Eurazeo–terralayr deal highlights a broader shift in energy investment priorities. As renewable penetration rises, value is increasingly migrating from generation alone toward system-level capabilities such as storage, flexibility and digital optimisation.

For investors, grid-scale batteries and flexibility platforms are moving from niche infrastructure into strategic assets essential for power system reliability. For policymakers and utilities, they represent a prerequisite for scaling renewables without compromising stability.

With this financing, terralayr enters its next growth phase as Germany’s energy transition moves deeper into the infrastructure and systems layer.
