Liz focuses her practice on electricity regulation and represents clients before the Federal Energy Regulatory Commission (FERC). With a passion for the complexity and ever-changing nature of the issues facing the electric industry, Liz advises clients regarding the Federal Power Act and related federal and state statutes.

Liz assists regional transmission organizations (RTOs) throughout complex FERC rulemaking proceedings and other matters.
