Diana Liebmann
Partner
Haynes and Boone, LLP
Diana Liebmann’s legal advocacy and regulatory experience have helped clients through multiple restructurings of the electric power markets in Texas, to create the rules for the evolving ERCOT market. Diana understands the risks inherent in certain transactions under constantly changing market rules and dynamics. She has represented clients in analyzing and structuring power supply arrangements for both wholesale and retail sales, including assisting LNG facilities with structuring power transactions. Diana works on both utility-scale generation project development and with smaller projects including end use consumers on-site and back-up generation. She was instrumental in developing the current postage stamp transmission pricing mechanism in the Competitive Renewable Energy Zone proceedings to obtain access to markets for their generation, and in interconnecting on-site generation both with ERCOT and transmission and distribution utilities.
Diana’s broad transactional experience and in-depth focus on the details of wholesale and retail power regulation and market structure give her the ability to effectively guide clients with respect to structuring transactions, compliance, and in the investment and deployment of capital in electricity markets. Diana is valued as a leading energy lawyer by Chambers USA, Chambers and Partners, and is described as a “utilities guru” with a “great understanding of the Public Utility Commission.” She has become a go-to lawyer for regulatory matters relating to the Public Utility Commission of Texas, the Electric Reliability Council of Texas, the Southwest Power Pool, the Federal Energy Regulatory Commission and in various other state commission, regional entity and North American Electric Reliability Corporation proceedings.
