Diablo Canyon Power Plant Closure


Economic Future 

In June 2016, Pacific Gas & Electric Company announced the permanent closure of the Diablo Canyon Power Plant (DCPP), the last nuclear power plant in the western United States. For the last 30 years, DCPP has been the largest private employer in San Luis Obispo County; its impacts are far reaching, extending into every aspect of our economy. Beginning 2024, the closure will be the single largest economic impact in the County's history.


Economic Planning 

In 2017, the EVC is proud to have launched the economic planning of the closure of the Diablo Canyon Power Plant, the last remaining nuclear power plant in the western U.S. As the single largest employer in the County of San Luis Obispo, as well as the single largest property tax payer, the impact of the closure will likely be significant. The economic planning project on the closure is now being led by the County of San Luis Obispo and U.C. Berkeley by virtue of California Senate Bill 1090. 


Legislative Support

Senator William Monning introduced California Senate Bill 1090 to require the Public Utilities Commission to approve funding for the community impact mitigation settlement and employee retention program proposed by PG&E. SB 1090 will help address regional impacts of the DCPP closure by minimizing affects to local school districts and residents and by maintaining services for the community. The bill aims to comprehensively address the complex components associated with decommissioning the Diablo Canyon Power Plant by providing the following:

• Employee retention
• Community mitigation funding
• Greenhouse gas-free energy replacement
• The health, safety, and economic vitality of the region and the state



  • DCPP has been the single largest private employer in San Luis Obispo County for the past 30 years and currently employs approximately 1,500 employees with reported average salaries of approximately $157,000 per year.
  • The plant closure will be followed by a decommissioning process that is anticipated to take approximately ten years.
  • To date, the overall economic impact of DCPP is reported to be approximately $1 billion per year.
