More informationMore information

Praised by clients as a ‘go-to firm in this area’, Mayer Brown’s regulatory offering in the electric power space is often sought out in relation to the firm’s transactional capabilities, where it assists clients with the sale and purchase of assets such as generating projects and public utilities. The practice also handles FERC proceedings under the leadership of Mark Williams in Washington DC. Williams specializes in FERC-regulated M&A proceedings, which also form a key area of focus for DC-based Heather Feingold. Tray Smith left the firm in September 2023.
