Hello, County of San Luis Obispo County Board of Supervisors and Staff:
I've attached three files to support Californians for Green Nuclear Power's (CGNP's) Comments during the public comment period for the 29 September 2026 Public Meeting.
Those three files include the text from a 17 September 2026 San Francisco Chronicle Travel section article touting the Diablo Canyon lands as a tourist destination. The other two items were distributed to the public at the Diablo Canyon Lands conservation meeting.
CGNP attended the Diablo Canyon Lands conservation meeting on 23 September 2026 at the downtown SLO public library. CGNP has concerns that public access for the Diablo Canyon Lands could create land use conflicts and serve as a barrier to extended Diablo Canyon operations beyond 2030. CGNP continues to learn about actions taken to support the doctrine-based opposition of California Senator John Laird and California Assembly Member Dawn Addis.
As the earliest advocate for Diablo Canyon extended operations, independent nonprofit CGNP appreciates the longstanding support of the San Luis Obispo County Board of Supervisors for extended Diablo Canyon operations at least to 2045. Per a 2013 Cal Poly SLO study, Diablo Canyon generates at least a billion dollars in direct and indirect economic activity each year.
The massive Iberian Peninsula blackout on 28 April 2025 illustrated the danger of insufficient synchronous grid inertia from Spanish nuclear power plants - and excess low-quality power from solar and wind generation. Unfortunately, at least eleven people who were depending on reliable electric power died as a consequence of the blackout. The economic harms from lost productivity and damaged production equipment are measured in the equivalent of billions of U.S. dollars.
Diablo Canyon's safe, reliable, abundant, and zero-emission power is cost-effective. In a CPUC filing CGNP made on 28 September 2026, we showed the net cost of Diablo Canyon's power during the initial record period from September, 2023 to December, 2025 was a mere 1,7 cents per kilowatt-hour, a cost comparable to power from a large hydroelectric dam. Diablo Canyon typically annually produces more power than five Hoover Dams.
The County's best bet for ratepayers and the environment is to keep Diablo Canyon running well beyond 2045.

RE: Proposed Clean Energy Innovation Hub and DCPP Parcel P -
Subject: Proposed Clean Energy Innovation Hub and DCPP Parcel P
Dear Karen: I appreciated our short conversation earlier today regarding the future of Parcel P at the Diablo Canyon Lands Conservation Planning Project meeting at the SLO County Library.
As I informed you, I'm a tenacious advocate for the extended operation of Diablo Canyon Power Plant (DCPP.) In 2022, the American Nuclear Society awarded me a Presidential Citation for my pro-DCPP advocacy. In 2025, Rebecca Tuhus-Dubrow wrote a book titled Atomic Dreams: The New Nuclear Evangelists and the Fight for the Future of Energy https://www.amazon.com/Atomic-Dreams-Nuclear-Evangelists-Future/dp/1643753150 The chapter that highlights my advocacy is Chapter 14 - The Guy in the Headband. I would like to see DCPP continue to generate clean, firm power for its design lifetime which is about a century.
Per https://cms.calpolypartners.org/wp-content/uploads/2026/04/rfp.pdf I understand that you are the point of contact for a proposed Clean Energy Innovation Hub which would presumably exist at Parcel P. I believe that such a project is mutually incompatible with DCPP extended operations. You may be aware that the original DCPP site plan was for six reactors, not two. During the 2025 Gifford Fire in eastern San Luis Obispo County, two of the three 500 kiloVolt lines feeding the state's AC backbone from DCPP were turned off out of an abundance of caution during the wildfire. The remaining line was able to carry the equivalent of about 1 1/2 reactors of power to the AC backbone. That fact implies that the three 500 kiloVolt lines could carry the power from about 4 1/2 reactors to the AC backbone. Thus, the DCPP site has the capability for significant nuclear power expansion.
DCPP supplies the equivalent of five Hoover Dams of clean firm power each year to the California power grid. DCPP's power also possesses important properties such as the greatest amount of synchronous grid inertia to maintain grid frequency stability. Thus, DCPP supplies an essential grid reliability service to the California power grid.
I'm requesting clarification regarding the plans for the proposed Clean Energy Innovation Hub in the event that DCPP continues to generate power, which I believe is the best and highest use for Parcel P.

Gene Nelson, Ph.D. CGNP Senior Legal Researcher and President
