Our Partners

Greengate Biogas is being jointly developed by CIP’s CI Advanced Bioenergy Fund I, Atlas Renewables Ltd and Energex Partners Ltd.

CIP is the world’s largest dedicated fund manager within greenfield renewable energy investments and a global leader in offshore wind. The funds managed by CIP focus on investments in offshore and onshore wind, solar PV, biomass and energy-from-waste, transmission and distribution, reserve capacity, storage, advanced bioenergy, and Power-to-X. 

Since its inception in 2012, CIP has raised EUR 28 billion and is managing 12 funds which build upon 5 different fund strategies.

CIP’s CI Advance Bioenergy Fund I (CI ABF I) is a dark green fund focusing on investments in advanced bioenergy infrastructure in Europe and North America. Investments are based on sustainable feedstock such as waste wood, agricultural biowaste, and household and industrial biowaste. The offtake products include green gas and green fuels, such as biomethane. The CI ABF I reached first close with EUR 375 million in commitments in April 2022. The fund reached final close in October 2023 with commitments of EUR 750 million.

CIP in Ireland


In 2023, CIP acquired 50% of Statkraft A/S’s offshore wind portfolio in Ireland. The JV was awarded an ORESS 1 contract through North Irish Sea Array (NISA), a fixed-bottom offshore project among the first commercial scale offshore wind projects in Ireland. In 2024, CIP has acquired a majority stake in Irish solar developer Elgin Energy.

Want to Supply Us With Feedstock?

Greengate will be processing over 600,000 tonnes of feedstock (manures and organic waste) in each of its plants which we envisage will be supplied by farmer led feedstock co-ops. We are keen to hear from farmers around Ireland who may be able to provide supply.
