About Rachael

Rachael Marsh draws on her years of experience as an attorney at the Federal Energy Regulatory Commission (FERC) to advise stakeholders in the energy industry on matters with a nexus to FERC and other federal and state policymakers, including on issues related to the energy transition. She represents companies in controversies and rulemaking proceedings before FERC and helps clients anticipate and understand potential FERC actions.  Rachael also is highly experienced in FERC settlement negotiations.  Her clients include pipeline companies, independent power producers, utilities and renewable power companies.

Rachael served as a FERC attorney from 2014 through 2021. She was involved in nearly all aspects of the Commission's substantive work, including as a trial attorney in the Office of Administrative Litigation, an attorney-advisor in the Office of the General Counsel and most recently as lead legal advisor to former Chairman Neil Chatterjee. She was instrumental in shaping and advancing a suite of reforms supporting the energy transition, including landmark rulemakings on battery storage and distributed energy resources. Rachael also served as the Chairman's chief reviewer and advisor on a broad range of legal issues, including market design and other matters in the PJM footprint; natural gas pipeline rate matters in the western United States; utilities in the US Southeast; bankruptcies; and high-profile enforcement matters.
