With new spending and regulations coming down the pike in the U.S., as well as the war in Ukraine continuing to complicate the picture, Jenner & Block is investing in its energy practice, adding a veteran litigator and practice leader from Skadden, Arps, Slate, Meagher & Flom.

The firm this week announced the addition of John Estes III, the former head of the energy regulatory group at Skadden whom Jenner leaders described as a “FERC legend” for his work on enforcement cases involving electricity, natural gas and markets.
