Isomer Project Group was contracted by an investment fund to perform technical confirmatory due diligence on a portfolio of dairy Renewable Natural Gas (RNG) assets, including assets currently under construction and in development. The scope included a technical process review, an opinion on the status of design, engineering, and construction plans, and an operational review of the existing assets, including maintenance logs and uptime tracking data. Isomer also reviewed and commented on the portfolio financial model, providing technical input including capex spend to date and proposed budgets to complete the open projects, while also commenting on the projects' ability to generate renewable tax credits. Isomer also reviewed the developer's execution plan and conducted site visits to the existing assets as well as the projects currently under construction. A Due Diligence Report was produced in support of the project's financial closing.
