Ralph Izzo, executive chair of the Public Service Enterprise Group Inc. (PSEG) board of directors, will join TerraPower’s Board on January 1, 2023. An internationally recognized leader in the energy industry and public policy arena, Izzo brings more than 30 years of experience at the state and federal levels to guide and advise TerraPower’s work solving the world’s toughest challenges through nuclear innovation.

“I am delighted to welcome Ralph to the TerraPower Board as we seek to lead our country’s movement toward net zero with our advanced nuclear technologies,” said Chris Levesque, TerraPower President and CEO. “His commitment to supporting clean and reliable energy sources and his expertise as a utility executive will enhance our ability to broadly deploy NatriumTM plants[1] and bring additional innovative nuclear technologies to market.”

“I am excited to join TerraPower’s Board and be part of developing and deploying their technologies that are critically important in our worldwide efforts to mitigate climate change and assure growing economies energy security, all while maintaining reasonable energy costs,” added Ralph Izzo.

Izzo will step down as executive chair of PSEG’s board of directors on December 31, 2022. Prior to this role, Izzo led PSEG’s shift toward clean energy and re-commitment to maintaining its nuclear fleet during his 15-year tenure as chairman of the board, president and chief executive officer. Izzo also served as president and chief operating officer of Public Service Electric and Gas Company (PSE&G), an operating subsidiary of PSEG, where he is currently a member of PSE&G’s board of directors. Since joining PSE&G in 1992, Izzo has held several executive positions within PSEG’s family of companies, where he is credited with creating a company culture committed to tackling climate change, building reliable energy infrastructure, educating customers on energy efficiency, reducing PSEG’s carbon emissions, and leading the company’s net zero by 2030 commitment.

Izzo serves on numerous corporate, local and collegiate boards of directors and advisory boards, where he provides his innovative energy, engineering and corporate expertise. He is also the former chair of the Nuclear Energy Institute and a member of the U.S. Department of Energy’s Fusion Energy Sciences Advisory Committee.
