Our 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 in 2024, the closure will be the single largest economic impact in the County’s history.


Economic Planning 

In partnership with the local government, educational offices, chambers of commerce, and businesses, the EVC is managing the economic planning project with two phases: 

PHASE 1: Regional Economic Analyses, that includes economic impacts of the closure on our local communities
(June 2018 - January 2019).

PHASE 2: Economic Strategic & Implementation Plan, develop a strategy to offset the closure’s negative impacts , increase the region’s resiliency, and help diversify the region’s economy.


Stakeholders must work collaboratively to mitigate closures impacts on citizens and local businesses. This economic planning project is structured as a public/private partnership. The EVC is committed to managing this important economic planning effort on behalf of the region with input from the community. 

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 


Our Mission 

The EVC mission is to stimulate the economic vitality of San Luis Obispo County, generate jobs, increase investment in the community and promote the start-up, growth and attraction of businesses.

“The success of our region’s resiliency through economic changes hinges on the success of our collaboration and shared ownership of our regional challenges and opportunities.” Michael Manchak

The EVC has an active role in helping the region focus on the future and establish an Economic Strategy, building off of the efforts we set forth in the County’s Economic Strategy which was last updated in 2015. 


Economic Strategizing 

San Luis Obispo County and its cities are planning for the changes due to the Diablo Canyon closure. We are also looking to establish long-term solutions that diversify the economy beginning in 2019. The EVC played a vital role in planning and implementing the County’s 2011 economic strategy, and we are engaging with stakeholders by planning for the future. This economic planning effort will advance our previous countywide strategy by building off of our current clusters of industry and help us to identify new ones.

  • 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.
  • In its role, the EVC will oversee a consulting firm (VITAL Economy, Inc.) to help the community mitigate the negative impact to our local economy. The consultant was selected from over twenty firms who submitted qualifications. The consultant selection committee was comprised of representatives from private business, education, local government, chambers, and the EVC.
