Heygaz secures platform financing to expand European biomethane portfolio

European biomethane platform Heygaz has closed what it describes as a first-of-its-kind corporate financing deal, with an initial tranche enabling the immediate development of more than 15 biomethane projects across the continent.
The financing provides operational flexibility to support the development, construction and commissioning of a diversified portfolio of biomethane projects, as well as the expansion and conversion of existing biogas plants to biomethane production.
Headquartered in Madrid, Heygaz operates across the full biomethane value chain, from waste collection to commercialisation of biomethane volumes in European markets.
Heygaz also maintains a pipeline of greenfield projects at advanced stages of development, with several new constructions planned for 2026 and 2027. In parallel, the company is pursuing an acquisition strategy targeting biogas plants for conversion to biomethane across Europe.
The transaction represents a key milestone in Heygaz's growth strategy, which aims to reach 1.5 TWh of biomethane capacity by 2030.
Financing has been provided by a group of institutional infrastructure debt investors and commercial banks, reflecting what the company says is strong appetite for long-term renewable infrastructure assets.
Fernando Sarasola, executive chairman of Heygaz, said: "Closing this financing marks one more milestone for our platform, confirms the robustness of our project pipeline and the strong capabilities of our team in delivering construction, operations and securing the commercialisation of our biomethane."
Pauline Fiastre of InfraVia Capital Partners added: "The support from this group of lenders allows us to accelerate the delivery of Heygaz's strategic plan and strengthens our ambition to consolidate it as a leading biomethane platform in Europe."
Heygaz was advised by DC Advisory as exclusive financial adviser, with A&O Shearman acting as legal counsel.
Technical due diligence was provided by DNV, commercial due diligence by Oliver Wyman, legal due diligence by Eversheds Sutherlands, and tax due diligence by EY.
