Who We Are

The firm’s renewable energy group comprises more than 80 lawyers across offices in New York, Los Angeles, Washington, Mexico City, São Paulo, Moscow, Warsaw, Dubai, Istanbul and London. Chadbourne’s renewable energy team includes the industry’s top tax equity advisor, some of the industry’s leading energy regulatory lawyers, several of the industry’s top renewable energy finance lawyers and one of the leading biofuels lawyers.

The 2011-2013 editions of Chambers Global ranked Chadbourne number one for US energy, renewables and alternative energy. In addition, The Legal 500 (2012) distinguished Chadbourne’s strengths in the US, Poland, Russia and the CIS, Ukraine and the United Kingdom. In 2013, Chambers USA ranked us number one in the US renewables market based on peer reviews and year-round polling of corporate law departments. Previously we received the Chambers USA Award of Excellence in Energy Projects: Power (including Renewables) for our cutting-edge work on conventional and renewable energy projects.

Our vast project experience, coupled with our regulatory and financial know-how, delivers value to our clients in all aspects of renewable energy development. Examples in specific industries include:


Chadbourne is one of the leading law firms in the development and financing of wind power projects and for capital market and corporate transactions within the wind power industry. The firm is committed to expanding the wind power sector and we have been actively involved in more than a third of the installed wind capacity in the United States. As one of the most seasoned teams in this business, we have negotiated the first sale leaseback of a wind farm, the first federal loan guarantee for a wind project from the Department of Energy and the first two prepaid service contracts on wind farms. We have been counsel on the vast majority of US wind tax equity deals involving Treasury cash grants.


Solar energy is one of the fastest-growing segments in the renewable market today. Chadbourne represented most of the major developers during the first wave of solar energy growth in the 1980s. As a result, the firm has a long-standing history as a leader in the solar energy field. We are now at the center of the resurgence in the solar energy market, where we use our skills and extensive experience to help clients with the development, financing and tax structuring of solar projects and solar companies.

Chadbourne lawyers prepared a “Guide to Federal Tax Incentives for Solar Energy,” the manual on tax issues in solar projects that has been widely circulated in the industry and is available on the website of Solar Energy Industries Association.


Chadbourne’s experience with geothermal acquisitions, projects and corporate financings dates back to the 1980s. Since then, we have worked for many prominent geothermal companies on projects in the western US, Indonesia, the Philippines, Kenya, Nicaragua and Guatemala. The firm has acted as counsel in a series of sale-leasebacks of US geothermal projects and has handled the first portfolio “partnership flip” deal in the geothermal sector. We also handled the initial public offering of the first foreign geothermal company to list on the New York Stock Exchange.


Chadbourne lawyers have extensive experience in developing and financing both US and international hydroelectric projects. Internationally, the firm has acted for developers in Uganda, Chile, Bolivia, Mexico, Colombia, Peru, Venezuela, Brazil, Ecuador, Panama, Honduras, Switzerland, Bosnia, Canada, Nepal, the Philippines and Tajikistan. We have also represented the developer in two leading hydroelectric projects in the US.


Chadbourne has been active in the growth of the biomass industry as we have worked on a wide range of biomass projects both in the US and in the Caribbean basin. We have advised clients on projects involving hog fuel and black liquor boilers at paper mills and power plants that burn municipal solid waste, bagasse, rice hulls, peat, poultry litter, wood and other forms of biomass. Our team also has a deep understanding of the industry’s political issues. Chadbourne lawyers have lobbied Congress and the Treasury Department on various matters tied to gasification of waste fuels.

Biofuels & Ethanol

Our renewable energy team is recognized as a leader in the biodiesel industry, and we have significant experience with reviewing and negotiating construction contracts, ethanol marketing agreements and feedstock agreements. Our strong reputation is consistently validated through publications such as Ethanol Producer, Latin Lawyer, Fuel, Project Finance International, BioFuels Journal and Infrastructure Journal.

Landfill Gas

Chadbourne lawyers are at the forefront of the expansion in the landfill gas industry. We have been involved in more than 130 landfill gas projects. Our lawyers are committed to growing this industry, and we have lobbied on two occasions to extend tax credits for landfill gas projects.


Along with the rise of solar, wind and other intermittent source power providers, utilities increasingly require that these intermittent energy producers include energy storage solutions in projects to ensure operability during peak hours. Chadbourne lawyers advised on some of the first energy storage projects in the US and continue to build on this experience around the world.
