Experience

• Achieved a favorable ruling as lead counsel in the Texas Court of Appeals before the Texas Supreme Court reversed the decision for RWE in administrative appeals challenging PUCT orders on electricity pricing during Winter Storm Uri. Named one of Law360’s “Biggest Energy Decisions in the First Half of 2024,” these cases raised novel questions about the Commission’s authority over ERCOT and involve multiple major market participants. 
• Represented Texas-New Mexico Power Company (TNMP) in securing approval to amend its Certificate of Convenience and Necessity for a 138-kV transmission line serving a rapidly expanding region in Texas. Led the contested case through trial, overcoming regulatory challenges, resulting in a favorable PUCT order in May 2024. The project enhances grid reliability and addresses increasing demand for TNMP and the broader ERCOT market.
