Mandy Kimbrough

Mandy Kimbrough’s practice primarily focuses on advising participants in the competitive electric market in ERCOT. In her twelve years of practice, Mandy has developed deep expertise regarding the detailed rules that govern the Texas wholesale and retail electricity markets. She represents power generation companies, wholesale market participants, and retail sellers of electricity before the Public Utility Commission of Texas (PUCT) in contested cases, rulemakings, and projects. She also provides regulatory advice to parties involved in mergers, acquisitions, asset purchases, and other transactions involving power generation facilities, wholesale sales businesses, and retail sales businesses in Texas. Mandy’s clients include large and small wholesale and retail market participants and investors in those companies. She routinely advises clients with respect to a wide range of regulatory compliance issues in the ERCOT market; assists clients with regular reporting requirements; provides clients with regular updates on changes to applicable regulations; and performs regulatory due diligence and obtains necessary regulatory approvals, both at the PUCT and at the Railroad Commission of Texas (RRC) (typically for natural gas pipelines associated with power generation facilities). She also represents clients in appellate matters, and, prior to entering private practice, clerked for Judge Priscilla Owen of the U.S. Fifth Circuit Court of Appeals.
