What is project finance? What makes project or structured finance so relevant for large renewable energy infrastructure? What concepts are paramount when developing utility-scale wind and solar energy, battery-based energy storage, or green hydrogen projects? How are such projects structured to be bankable? These questions - and many more - are answered throughout this book, from technical, financial, and legal perspectives, thus offering real-world examples to bridge the gap between theory and practice. Now in its second, updated and expanded edition, the book details the role of each stakeholder in the development of renewable energy projects, the interconnection between all agreements, and the financial process from fundraising to financial close. It also covers due diligence, risk analysis, project investment valuation, and much more. A commented glossary enables readers to unpack the jargon used in project finance for renewable energy and investment management, while numerous creative figures and comprehensive tables aid understanding. The new edition explores the implications of a just transition to a low-carbon economy. It includes expanded chapters addressing stochastic and unforeseen changes that affect the financing of renewable energy projects, as well as new chapters on carbon markets and pricing, energy transition finance, ESG and sustainable investing, portfolio management, blended finance and decarbonization funds, and project finance applied to battery energy storage systems (BESS) and green hydrogen infrastructure. Offering a complete picture of the discipline, Introduction to Project Finance in Renewable Energy Infrastructure will be of value to professionals such as lawyers, bankers, developers, engineers, and academics interested in understanding the processes and components of project finance in renewable energy infrastructure - across both private and public-private contexts, and with mature or emerging technologies.
