Haynes and Boone, LLP is among the leading Texas firms in Energy: State Regulatory & Litigation (Electricity), according to the Chambers USA 2021 rankings (Chambers and Partners).

Chambers USA ranked Haynes and Boone’s Energy Regulatory Practice among the Top 13 in the state, saying the Haynes and Boone team provides: “in-depth service to clients across regulatory and litigation matters in the electricity sector, including issues arising from transactions. Has had a number of recent successes in court. Maintains a high profile for its industry advocacy before regulatory bodies, with recent engagements including ERCOT and PUCT proceedings. Additional capabilities include advising on matters before the TCEQ and EPA.”

Haynes and Boone Partner Diana Liebmann, the head of the firm’s Power and Renewables Practice and the administrative partner for the firm’s San Antonio office, was one of eight lawyers that Chambers USA ranked Band 1 in Texas in Energy: State Regulatory & Litigation (Electricity).
