AddiGen — Europe's long-duration energy storage developer

Company

Building a long-term European platform.

AddiGen is an infrastructure developer with the ambition to own and operate the assets it builds — a platform measured in decades.

Our story

Established to deliver storage at infrastructure scale.

AddiGen develops large-scale CAES and BESS infrastructure across Europe — from origination and permitting through to financing and long-term ownership.

What makes AddiGen different

Six principles, one platform.

End-to-end development capability

Origination, permitting, grid connection, commercial structuring and financing are delivered by one disciplined development platform.

Complementary technology approach

CAES and BESS are combined so the portfolio serves both short-duration flexibility and long-duration security of supply.

Backed by institutional capital

Experienced institutional investors support the platform with the strength to advance projects and make long-term decisions.

Disciplined project selection

Projects proceed only where grid need, geology and market conditions align — storage is built where the system requires it.

Capital recycling model

Equity realised from mature projects is redeployed into the next generation, compounding the platform without dilution.

Deep project knowledge

The team brings direct experience of European storage development, subsurface engineering and infrastructure delivery.

Our mission

"To build a leading European platform for long-duration energy storage, delivering the infrastructure that makes renewable power systems work."
