Our impact

French biogas assets platform with Evergaz - Evergaz SA, France


As part of its strategic partnership with Evergaz SA, Meridiam acquired a co-controlling stake (28%) in Evergaz SA in 2018.

Evergaz SA provides biogas plant operation and management services and engineering services to biogas projects in Europe.

Evergaz SA is a shareholder in biogas projects in Western Europe: in France (directly or through BMP), in Germany and in Belgium (2 biogas cogeneration units). In 2020, Evergaz expanded its activities to Natural Gas Vehicle (NGV) charging stations. Please refer to the “Evergaz biogas asset companies” asset sheets.
Evergaz also owns a 20% stake in the C4 group, a company owning a portfolio of 10 brownfield biogas power plant in Germany, for a total production capacity of 14 MWe.

With the support of Meridiam, Evergaz is now an integrated developer, asset owner and operator of biogas facilities with a strong lead in France and a unique pan-European positioning.

Thanks to its integrated strategy, Evergaz can optimize value creation at every step of the biogas supply chain. It can rapidly adapt to new industry trends, build strong partnerships, and uniquely leverage knowledge sharing and economies of scale to develop new projects efficiently or seize acquisitions opportunities.
