Overview

Tyler O’Connor is an energy litigator and public policy leader in Crowell & Moring’s Washington, D.C. office, where he represents clients in the courts, in arbitration forums, and before the Federal Energy Regulatory Commission (“FERC”) and Department of Energy (“DOE”). His recent work includes advising companies on the Inflation Reduction Act and Infrastructure Investment and Jobs Act, representing clients in rulemakings and on Capitol Hill, and litigating energy disputes at FERC. Washingtonian Magazine named Tyler one of the “500 Most Influential People Shaping Policy in Washington D.C.” in 2023.

Prior to joining Crowell, Tyler served as the Energy Counsel to the House Energy and Commerce Committee, where he played a leading role in drafting the Inflation Reduction Act (IRA) and Infrastructure Investment and Jobs Act (IIJA). He was the lead House lawyer responsible for the Federal Power Act and Natural Gas Act and worked extensively on transmission, energy cybersecurity, and energy supply chain issues. His work brought him into frequent contact with senior administration officials, including at FERC and DOE, as well as congressional leadership. As the staffer responsible for emerging technologies, including hydrogen and offshore wind, as well as the Loan Programs Office, Tyler has been at the center of energy policy discussions.

In addition to helping clients navigate the IRA and IIJA, 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 proceedings and DOE enforcement actions, and in suits against the Department of Interior, Environmental Protection Agency, and the U.S. Army. In addition to his trial practice, Tyler has co-authored numerous U.S. Supreme Court and appellate briefs on energy, environmental, civil rights, torts, and other issues.

Tyler maintains a very active pro bono litigation practice. He has co-authored U.S. 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.

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.

In a Move Affecting the Future of Data Centers, DOE Directs FERC to Act On Large Load Interconnections

On October 23rd, the U.S. Department of Energy (“DOE”) sent a letter to the Federal Energy Regulatory Commission (“FERC”) containing an Advance Notice of Proposed Rulemaking (“ANOPR”) with principles for all large load interconnections across the US, including those co-located with generating facilities.[1] Significantly, the Secretary of Energy states that the interconnection of large loads to the transmission system “falls squarely” within FERC’s jurisdiction, thus weighing in on a dispute that has been pending before FERC for over a year. This move appears to be a reaction to the continued pendency before FERC of the colocation dockets[2] and a technical conference on colocation held almost a year ago.[3]...
