Erica guides clients and litigates in regulatory matters concerning natural gas and oil pipelines and electric utilities.

Erica uses her extensive experience to ensure that natural gas, crude oil, refined products and natural gas liquids producers are able to protect their business interests in administrative litigation and settlement proceedings before the Federal Energy Regulatory Commission (FERC) and in commercial negotiations.

Erica litigates cost-of-service and market-based rate cases and other proceedings challenging rates and tariffs filed by oil and natural gas pipelines and electric utilities. She advises clients on FERC jurisdiction and regulation under the Interstate Commerce Act, the Natural Gas Act and the Federal Power Act and helps identify regulatory solutions for business issues. Erica also advocates for stakeholders in energy policy matters before federal and state regulators.

Prior to entering private practice, Erica was a Trial Attorney at the FERC's Office of Administrative Litigation, where she negotiated and litigated natural gas pipeline and electric utility rate cases on behalf of the public interest.
