Storage Offensive with Signal Effect: Terra One Secures €150 Million Investment from Aviva Investors for Energy Transition Projects

Berlin (Germany) - Berlin-based company Terra One has secured up to €150 million in mezzanine financing from Aviva Investors. With this capital, the battery storage specialist aims to enable investments of up to €750 million.

The financing puts Terra One in a position to implement several ready-to-build projects in Germany. According to the company, the agreement marks a strategically important step toward accelerating the expansion of large-scale battery storage. The planned storage systems will have a total capacity of around 3 GWh – enough, according to Terra One, to supply approximately 20 percent of German households with electricity for one hour.

„This financing is a milestone for Terra One and for the energy transition in Europe,” said CEO Tony Schumacher. The hybrid financing structure provides the scalability and flexibility needed to establish the company as a leading independent storage provider.

Aviva Investors, a global asset manager, is strengthening its position in the sustainable infrastructure sector through this investment. “We're investing in Terra One because the company has proven its ability to deliver projects quickly, reliably, and to the highest standards,” said Adam Irwin, Director of Infrastructure Equity at Aviva Investors.

The transaction was supported by Elgar Middleton Infrastructure & Energy Finance LLP and the law firm Hogan Lovells.
