Terralayr secured major funding to scale its battery storage ambitions

Swiss-based BESS owner and operator Terralayr has received fresh funding to accelerate its battery energy storage systems goals, raising €192 million (USD 224.6M) while pressing the gas pedal down fully in Germany.

The company noted it has four battery storage systems currently connected to the grid, with ten more under construction, with a total capacity of 150 MW. An additional 200 MW is ready for construction and awaiting final decisions. German media, including finance trade paper Handelsblatt, reported that “within the next 36 months,” Terralayr plans to increase the capacity of its battery storage systems to 1 GW.

Terralayr was founded in 2022 and has raised several rounds, including its last round, a Series C of €77 million (USD 90 million), to expand both its physical assets in Germany, along with its cloud-based product called Layr, a digital battery energy market platform, which the company says offers flexibility-as-a-service. The platform virtualizes battery assets, and through aggregation and control sophistication, it can provide route-to-market, infrastructure, and tolling solutions for its own batteries, along with third parties.

In late 2025, it announced “Enhanced Trading of Flexibility” or an ‘ETF’ platform that allows competing optimizers Entrix, Suena, and The Mobility House, to trade simultaneously on a single battery asset, following a similar idea around risk-spreading benefits of Exchange Traded Funds (also known as ETFs) in financial markets.

Terralayr was also making strong progress in signing offtake deals with majors including Vattenfall and RWE.

Philipp Man, co-founder and CEO of Terralayr, said in a press release, “We are very happy to welcome Eurazeo to our shareholder base. Their backing is essential in allowing us to accelerate the build-out of much needed flexibility infrastructure in Germany. This capital raise will enable us to increase the pace of our asset growth in Germany, which is critical for the scaling of our digital platform. This will make us an even stronger partner to utilities, asset owners, flexibility traders, and other users of flexible power assets.”

Funding

Eurazeo, through its Eurazeo Transition Infrastructure Fund (ETIF), was announced as the lead of the €192 million equity financing round, which also included an €80 million upsizing option, alongside RIVE Private Investment, Creandum, Norrsken, Earlybird Venture Capital, and Picus Capital. The headline figure of €192 million is effectively in two parts: €112 million invested now, and an additional €80 million if projects progress as planned.

The announcement didn’t reveal Terralayr’s valuation.

Melissa Cohen, co-head of Infrastructure at Eurazeo, said: “Terralayr develops and manages infrastructure that addresses a fundamental need for flexibility and stability in the power grid. We believe Terralayr is well-positioned to contribute to Germany’s energy transition by developing a solid asset base, underpinned by its virtual marketplace. We are very pleased to support Terralayr’s co-founders Philipp Man and Ludwig Wurlitzer, and the entire Terralayr team in this phase of the company’s growth.”
