Tyler O’Connor is an energy litigator in Crowell & Moring’s Washington, D.C. office, where he represents clients in the federal appellate and trial courts, arbitration, state court, and before the Department of Energy, Federal Energy Regulatory Commission, and the Department of Interior.

Tyler represents energy industry clients in civil litigation, enforcement matters, and in disputes against the government. He has successfully represented clients in bet-the-company litigation, including in multi-hundred million dollar contract disputes, in FERC and DOE enforcement actions, and in suits against the Department of Interior, EPA, and the Army. In addition to his trial practice, Tyler has co-authored numerous Supreme Court and appellate briefs on energy, environmental, civil rights, torts, and other issues.

Representative engagements include:

  • Successfully representing an independent power producer in a multi-hundred million power purchase agreement dispute with a large California utility.
  • Securing multiple TROs in state court over the course of one-month in bet-the-company litigation on behalf of a company that develops financial products for energy merchants and commodity trading firms.
  • Successfully representing a battery storage developer in a FERC dispute involving PJM’s recalibration of its methodology for compensating energy storage projects.
  • Obtaining a significant damages award on behalf of a client in a multijurisdictional dispute involving breach of contract and allegations of fraud, ultimately resulting in a favorable global settlement for our client.
  • Representing a pipeline in a non-public FERC Office of Enforcement investigation, which was resolved without any further action by the agency. 
  • Resolving claims by the Department of Energy’s office of enforcement against manufacturing clients alleging violations of energy conservation standards under the Energy Policy Conservation Act.
  • Securing victory in the Court of Federal Claims on the theory that the government effectuated a taking of a real-estate developer’s property in violation of the Fifth Amendment to the U.S. Constitution.

In addition to litigation, Tyler represents renewable energy developers in their development, financing, and disposition of solar and wind assets. He also represents corporate buyers in their negotiation of renewable power purchase agreements.

Tyler maintains a very active pro bono litigation practice. He has co-authored Supreme Court and D.C. Circuit amicus briefs on behalf of the American Bar Association and NAACP Legal Defense and Education Fund, respectively; served as co-counsel with the ACLU in securing a major First Amendment victory at the U.S. Court of Appeals for the Fourth Circuit; first-chaired a criminal jury trial in Maryland state court on behalf of an indigent client; and counsels refugees seeking asylum in the United States.

Prior to joining the firm, Tyler clerked for the Honorable Catharina Haynes on the U.S. Court of Appeals for the Fifth Circuit. Tyler received his J.D. magna cum laude and Order of the Coif in 2014 from the Emory University School of Law, where he was a member of the school’s law review.
