About us

We are ju:niz – an innovative, growth-orientated group of companies with
medium-sized roots and a clear goal: to play an active role in shaping the energy transition.

Since our first company was founded in 2009, we have developed into a leading player in the field of sustainable infrastructure projects through targeted start-ups and strategic developments. Our strength lies in the close integration of our business areas – from site acquisition and project development through to the economically successful operation of our large-scale battery storage systems.

With our battery storage solutions, we create the necessary flexibility for a stable, decentralised energy system. We relieve the strain on grids and support the integration of renewable energies into our energy infrastructure.

Our vision

We are powering the transition to renewables to create a world where people can live and work in a sustainable way.

Our namesmake

Our company name “ju:niz” was chosen as a tribute to Eunice Newton Foote, a pioneer in climate research

Eunice Newton Foote

Eunice Foote lived in the 19th century and discovered the connection between atmospheric carbon dioxide concentration and global warming. She conducted experiments to investigate the effect of solar radiation on hermetically sealed glass tubes filled with various gases. She used this experimental setup to demonstrate the absorption of solar heat radiation by carbon dioxide and water vapor. When she analyzed the results, she identified a possible cause for climate change events.
