Berlin, 6 May 2025 - Partnership announcement: ENGIE and terralayr

How can solar and wind power be used exactly when it’s needed?

Battery storage (BESS) is the answer — a key to a stable, sustainable energy system.

We’re excited to partner with ENGIE, one of the top 3 European / top 5 global leading green energy providers, on a new chapter in battery storage marketing.

Together, we’ve signed a short-term tolling framework agreement — or, as we say: virtual battery slice (or some lovingly call a Mini Toll).

ENGIE can now flexibly access our storage capacity from just a single day to several months or even years.

➡️ What is a Mini Toll or virtual battery slice?

It’s a dynamic tolling model: ENGIE secures operational rights to battery capacity for a fixed time and price — starting from just 24 hours. Their strength in structuring, trading, and portfolio optimization allows them to scale the use of our batteries precisely to market needs.

➡️ Why it matters:

Our cloud-based LAYR platform aggregates batteries across Germany into a virtual flexibility pool. ENGIE can rent virtual battery slices tailored to their needs — without physically connecting to each system.

This is how we make battery storage radically more accessible, modular, and scalable — to help stabilize renewables and power the grid 24/7.

Thank you especially to the amazing ENGIE team especially Martin Daronnat and Daniel Scheu

Together, we’re driving the energy transition — one battery (slice) at a time.
