Positioning
AddiGen develops large-scale CAES and BESS projects to support Europe's decarbonisation and renewable energy targets — building toward long-term ownership and operation of energy storage infrastructure.
AddiGen is an infrastructure developer, not a technology vendor. We understand the energy system, we develop complex infrastructure, and we are building a long-term platform — disciplined, system-led and European.
Development platform
From early-stage opportunity to long-term infrastructure — and back again.
AddiGen operates a repeatable development platform. Projects progress through a disciplined cycle, and realised capital returns to originate the next generation.
01
Originate
Identify early-stage energy storage opportunities across European markets.
02
Develop
Advance projects through feasibility, consenting and grid connection.
03
De-risk
Reduce technical, commercial and regulatory uncertainty step by step.
04
Finance
Structure projects to be investment-ready for institutional capital.
05
Partner / Sell Equity
Bring in long-term capital and delivery partners at the right moment.
06
Recycle Capital
Return realised capital to the development platform.
07
Develop the Next Generation
Reinvest in the next pipeline of storage infrastructure.
