Sienna Investment Managers (Sienna IM) has provided a €40 million bond financing to KEON, the largest independent biomethane producer in France. This financing will be carried out through three complimentary Private Credit strategies(1)  : Sienna Sustainable Infrastructure Debt III fund (SID3), Sienna Biodiversity Private Credit fund and F2E.  

Established 20 years ago, KEON is a mid-cap pioneer in methanisation, spanning the whole value chain and boasting an extensive portfolio of 11 operational biomethane plants, 4 under construction and at least 18 under development. The strategic 5-year credit line is set to bolster the acceleration of KEON’s green gas development ambitions, following a major fundraising round with a pan-European fund Marguerite in January 2022. 

This financing underscores the Sienna IM Group’s commitment to advancing the decarbonization efforts across Europe and highlights the increasing importance of diversified renewable energy sources in the transition towards a low-carbon economy. This vision for a greener future is shared by KEON.

Ronald Gaultier, Deputy Head of Infrastructure Debt Funds: “We are proud to contribute to the growth of such an experienced player in a key segment of Europe’s energy transition as KEON. This investment was structured in partnership with KEON and the advisors to properly address, at the same time, both the company’s strategic challenges and the promise made to investors. It illustrates very well Sienna IM’s strong positioning in favour of European decarbonization and European energy sovereignty”. 

Aurélien Lugardon, Chairman and founder of KEON: “20 years ago, when the KEON adventure began, the methanisation market was still in its infancy. Since then, we’ve helped to make it a pillar of the French energy mix, and above all a means of ensuring the long-term future of farming. This new funding gives us the resources to continue this transformation by becoming a fully-fledged producer of green gas. We’re putting this ambition at the service of the regions that are at the heart of all transitions: energy, agronomy and society. That’s why we’re defending a virtuous methanisation process that benefits, above all, people who make it happen and their local area.” 

Finergreen acted as the financial advisor for this transaction. Legal advisory services were provided by BCLP for Sienna IM and Jeantet for KEON.
