Boasting an impressive track record in renewable and clean energy power generation and electric transmission projects in the United states and internationally, Vinson & Elkins LLP showcases strength across wind, solar, geothermal, biofuels, carbon capture and storage projects. The team is often called upon by an array of investors, developers, lenders, and suppliers looking for guidance in all steps of the development, financing, acquisition and sale of renewable projects. Advising traditional energy clients  in their investments in or adoption of cleaner energy sources is a growing area of focus for the department. Houston-based John B. Connally IV  and Kaam Sahely , who splits his time between Houston and Austin, jointly head up the department. Sahely is regularly engaged by investors and developers in relation to large-scale projects and transactions involving renewable and sustainable energy assets.

Michael Joyce, whose areas of expertise cover wind, solar and storage issues, and Lauren Collins, who has helped develop some of the most complex renewable energy financing transactions in the market joined the Los Angeles office. Recent arrivals also include Aaron Prince in New York and Austin-based Sean Moran, who brings together knowledge in technology and power generation matters. Peter Marshall is a key attorney in Dallas for private equity funds and financial sponsors, while Danielle Patterson in Houston devotes her time to the energy and infrastructure sectors, advising on M&A, and project development.
