U.S. Secretary of Energy Ernest Moniz (L) and Chairman of the Federal Energy Commission Jon Wellinghoff participate in a panel discussion.

Portland, Oregon-based law firm Stoel Rives announced Monday that Federal Energy Regulatory Commission Chairman Jon Wellinghoff will join the practice upon his departure from the regulator. Wellinghoff submitted his resignation on May 28, but no date has been announced for his departure.

Stoel Rives is known for its energy law practice and claims to have “close to” 100 attorneys working on energy. However, several members of the energy team recently left for firms with “a large national presence,” according to The Oregonian.

“Stoel Rives is historically strong in the energy field, but has seen a significant string of recent departures, including renewable energy lawyers Steven Hall, Bill Holmes and Teresa Hill, as well as energy finance specialist David Benson and infrastructure expert David Hattery…The firm is also looking at the retirement of one of its senior energy partners, Marcus Wood,” the newspaper reported.

Wellinghoff is known as a strong renewable energy advocate, and what he lacks in terms of an existing client roster, he ostensibly makes up for with his Washington access.
