Katherine "Katie" Hantson is an attorney in Holland & Knight's Washington, D.C., office and a member of the firm's Public Policy & Regulation Group. Ms. Hantson focuses her practice on helping energy companies identify and secure federal funding and financing, including through the Infrastructure Investment and Jobs Act (IIJA) and the Inflation Reduction Act (IRA).

Ms. Hantson has nearly 15 years of public and private sector experience drafting, implementing and influencing energy policy and legislation. She also has significant knowledge of policy issues impacting U.S. manufacturers, including research and development of new technology, supply chain, tariffs and tax credits.

Prior to joining Holland & Knight, Ms. Hantson was an attorney on the government affairs and policy team of a Fortune 50 U.S. original equipment manufacturer (OEM). In that role, she engaged state and U.S. federal government entities on behalf of the company's onshore wind, offshore wind, wind turbine blades, hydropower, hybrid controls and electric grid businesses. 

Ms. Hantson spent nearly a decade working on defense energy policy at the U.S. Department of the Navy. As a senior attorney in the Department's Office of the General Counsel, she drafted and provided legal advice on first-of-its-kind energy policies that resulted in:

  • 1 gigawatt of new renewable energy production capacity installed on Navy and Marine Corps land
  • more than $600 million in third-party financed energy projects at Navy and Marine Corps bases
  • more than 77 million gallons of biofuel procured for use in Naval ships and aircraft
  • 200 electric vehicles leased to serve Navy and Marine Corps bases in California

During her time with the U.S. Department of the Navy, Ms. Hantson worked in the Office of the Chief of Naval Operations, Energy and Environmental Readiness Division, where she managed the Navy's installation and expeditionary energy investments. She also ran the Marine Corps' Experimental Forward Operating Base (ExFOB), a semiannual demonstration to evaluate and equip Marines with new technology to reduce battlefield energy and water consumption.

Ms. Hantson began her legal career at a consulting firm based in Washington, D.C., where she helped energy and clean technology companies secure U.S. Department of Energy funding and financing available through the American Recovery and Reinvestment Act (ARRA).
