John is co-head of Allen & Overy’s global energy practice and senior partner in the firm’s over 65 attorney U.S. projects and infrastructure team. His industry reputation illustrates a unique market perspective to deliver real world, practical solutions for a balanced mix of tax-equity, bank, private capital and other finance clients, along with sponsors, borrowers and developers.
Over the years, his creative approach to structuring often formed the foundation for many of the renewable market firsts. These have further paved the way for the current expansion of the industry towards all things energy transition. It also has increased opportunities for electric vehicle financing and their infrastructure, hydrogen and carbon capture, RNG and other advanced fuels, and energy transition manufacturing.
John attacks problems with a creative perspective that, when combined with his eidetic memory, allows him craft and execute the industry’s largest, most complex and cutting-edge transactions. His radically blunt feedback avoids wasted effort on the path to closing.
Based on his personal experience working on precedent setting projects, he compiled the best-selling book “Renewable Power Financing: Tax Credit Reference Guide,” providing industry-leading resources to structure and model these deals as well as pathways to mitigate risks and get them over the finish line. He does not waste time theorizing or writing; he is doing.
John is ranked Band 1 by Chambers and Partners USA for Nationwide Projects: Renewables and Alternative Energy (2017-2023) and Chambers Global for Projects: Renewables & Alternative Energy (2017-2022). He is recognized as a leading lawyer in Project Finance and in Energy: Renewable Power/Alternative Power in US Legal 500 (2023).
