When it comes to financing innovative energy projects overseas, Katy Gottsponer has a track record of putting together megadeals.

The Vinson & Elkins partner recently advised Chilean hydroelectric power generator Alto Maipo SpA in developing and financing a $2 billion project featuring two hydropower facilities, with most of the machinery below ground to protect natural habitats near the site. She advised Transelec S.A., the primary electric transmission provider in Chile, in financing a transmission line delivering energy to the Caserones copper mine. Gottsponer also handles natural gas projects in the United States and is secretary of the Energy Bar Association. — Jenna Greene
