If you live in Texas, chances are good you were personally affected by power outages on the ERCOT grid during the February 2021 winter storm.  The same is certainly true for any business involved in the power or natural gas markets.  Now that the dust has settled a bit and the search for solutions (and compensation) is well underway, this session will address the ERCOT outages and the fallout from every angle: what happened over those five days in February, why it happened, and what’s now happening in the aftermath from a regulatory, legislative, and litigation perspective.  

Diana Liebmann—a partner and Chair of Haynes and Boone’s Power and Renewables Practice—will draw on her deep knowledge of ERCOT and other power regulatory issues to discuss the outages, the financial impacts that rippled throughout the energy sector, the proposed legislative and regulatory solutions that followed, and areas to watch moving forward.  Andrew Guthrie—a partner in Haynes and Boone’s Appellate Practice Group with significant energy litigation experience—will discuss the ever-expanding areas of litigation that have emerged from the outages in both the power and natural gas spaces.

Andrew’s clients appreciate that he brings this skill to their cases, whether in briefs to the appellate court or arguments to the jury. But Andrew also knows that once that attention is earned, substance is paramount. So he works with clients to identify and communicate their most important arguments in a clear, thorough, and ultimately effective way.

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.
