We are thrilled to share this Special Edition COBT. Continuing our California Series, we had the opportunity to tour the Diablo Canyon Power Plant and sit down with Maureen Zawalick, Senior Vice President and Chief Risk Officer at PG&E Corporation, and Matt Crozat, Executive Director of Strategy and Policy Development at the Nuclear Energy Institute (NEI). Our visit was particularly timely as the U.S. Department of Energy recently awarded PG&E $271 million to support extended operations at Diablo Canyon (announcement linked here), while Governor Gavin Newsom recently indicated he would leave the decision on extending the plant beyond 2030 to the next administration (story here). Diablo Canyon produces nearly 10% of California’s electricity and is the state’s only operating nuclear power plant.
In our conversation, we explore Diablo Canyon’s history and critical role in California’s power system, the remarkable shift from plans to close the plant to extending its operating life, and how rising electricity demand, electrification, AI, and data centers are reshaping the state’s energy outlook. We discuss the broader nuclear renaissance, the importance of preserving and investing in existing nuclear plants, and the role nuclear power plays in providing affordable, reliable power and grid stability.
We cover the regulatory path for Diablo Canyon beyond 2030, the benefits of long-term planning for workforce retention and uranium procurement, and the plant’s impact on electricity affordability. Maureen shares PG&E’s approach to safety and risk management, including seismic safety, water use and environmental stewardship, wildfire, cyber, AI, and the importance of culture and processes in managing risk. We discuss Diablo Canyon’s relationship with the surrounding community and the importance of public engagement and outreach.
We end by looking ahead to new nuclear technologies and SMRs, changing attitudes toward nuclear energy at both the state and federal levels, California’s nuclear moratorium, and the need for durable, long-term energy policy. We also discuss the connection between affordable and reliable electricity, manufacturing, economic competitiveness, and where businesses ultimately choose to invest and grow. It was a fascinating discussion and an incredible opportunity to see Diablo Canyon firsthand.
