“[A] really good grasp of the litigation side of the practice.”

Chambers USA (Energy: Electricity Regulatory & Litigation)


Daniel heads up the Firm's energy markets and regulatory practice. He supports clients in the energy sector so they can operate confidently both in their day-to-day business, and when they are involved in transactions, subject to litigation or under investigation.

As a recognized authority on energy law, he is frequently called upon to advise and represent clients on regulatory issues across a broad spectrum of the energy industry, including the natural gas, oil pipeline and electric power industries. He regularly counsels clients on energy-related litigation, M&A transactions, project financings and contract negotiations.

Compliance and regulation are key considerations in the energy sector, and Daniel frequently represents clients before various federal and state agencies, including the Federal Energy Regulatory Commission (FERC) and the North American Electric Reliability Corporation (NERC). He has served as lead counsel in numerous FERC adjudicative and settlement proceedings.

Daniel regularly counsels clients in non-public and public audits, investigations and enforcement proceedings, and was a founding member of the Firm's Energy investigations, prosecutions, and enforcement team. He has also assisted clients in numerous judicial proceedings before federal and state courts.

Daniel developed and continues to manage the White & Case NERC Database (whitecase.com/nerc), a repository of summaries of NERC reports and notices which helps to facilitate industry compliance.
