California-- Offshore Wind Energy -- Introduction, Background, History

 Introduction

California is actively developing offshore wind energy as a key component of its renewable energy portfolio. The state has set ambitious goals to deploy 2 to 5 gigawatts (GW) of offshore wind power by 2030 and 25 GW by 204513. This initiative aims to provide clean energy for millions of Californians while establishing a new industry.

Offshore wind in California will primarily utilize floating turbine technology, as the deep waters off the Pacific coast are not suitable for fixed-bottom foundations23. The North Coast, particularly Humboldt County, has been identified as an ideal location due to its world-class offshore wind resources2.

Key developments in California's offshore wind energy sector include

-The California Energy Commission (CEC) has approved a strategic plan for deploying floating offshore wind1.

-In December 2022, the Bureau of Ocean Energy Management (BOEM) held a lease auction for offshore wind areas, resulting in over $757 million in winning bids3.

-The state has passed new legislation to facilitate offshore wind procurement and streamline permitting processes4.

-Efforts are underway to develop necessary infrastructure, including port facilities and transmission planning12.

California's offshore wind initiative is expected to create jobs, attract investment, and help the state meet its climate and clean energy goals12. The industry faces challenges, including environmental considerations and impacts on fisheries and coastal communities, which are being addressed through stakeholder engagement and strategic planning14

Background 

California is actively pursuing offshore wind energy development as part of its ambitious clean energy goals. The state aims to generate 2,000-5,000 megawatts (MW) of offshore wind capacity by 2030 and 25,000 MW by 2045, which could power up to 25 million homes2. This initiative is driven by the state's commitment to achieving 100% clean electricity and reducing greenhouse gas emissions.

Key Developments

-In July 2024, the California Energy Commission (CEC) adopted a comprehensive strategic plan to guide offshore wind energy development2.

-The plan focuses on deploying floating turbines off the central and northern coasts of California, where wind resources are particularly strong13.

-Two key areas have been designated for offshore wind development:

    -Humboldt Wind Energy Area (northern California)

    -Morro Bay (central California)4

Potential Benefits

    -Renewable Energy Generation: Offshore wind could potentially produce more than 150% of California's current electricity demand3.

    -Grid Reliability: Offshore wind can complement other renewable sources like solar, providing power during different times of day and seasons2.

    -Economic Impact: The industry is projected to create over 8,000 jobs during peak development, many of which will be unionized2.

Technological Considerations

California's offshore wind projects will utilize floating turbine technology due to the deep waters off the coast4. This approach allows for turbines to be placed farther from shore, where they are less visible and can access stronger, more consistent winds.

Challenges and Next Steps

The state is working on addressing various challenges, including:

    -Environmental impact assessments

    -Transmission infrastructure development

    -Port upgrades to support the industry

    -Stakeholder engagement, including fisheries and tribal communities2

As California moves forward with its offshore wind plans, it aims to position itself as a global leader in floating offshore wind technology and clean energy production.

california offshore wind energy history 

California's offshore wind energy history is relatively recent, with significant developments occurring in the past few years. In May 2021, the Biden-Harris Administration announced an agreement to advance areas for offshore wind off the northern and central coasts of California2. This was part of the administration's goal to deploy 30 gigawatts of offshore wind nationally by 20302.

On August 10, 2022, the California Energy Commission (CEC) adopted a report establishing offshore wind goals, setting planning targets of 2,000-5,000 megawatts (MW) by 2030 and 25,000 MW by 20452. These goals could potentially power 3.75 million homes initially and 25 million homes by mid-century2.

In late 2022, the federal Bureau of Ocean Energy Management (BOEM) awarded five leases in the Morro Bay and Humboldt wind energy areas4. The California Coastal Commission reviewed and conditionally concurred with Consistency Determinations prepared by BOEM for these lease areas4.

Key Developments

    -Environmental Assessment: In May 2022, BOEM issued a Finding of No Significant Impact for commercial wind lease and grant issuance in the Humboldt Wind Energy Area2.

    -State Initiatives: California set a target of 25 GW of offshore wind by 20453.

    -Project Proposals: In April 2018, several power development companies joined with Redwood Coast Energy Authority to explore creating a large-scale wind farm off the Northern California coast3.

While California has been a leader in onshore wind energy since the 1980s, offshore wind is a new frontier for the state. The deep waters off California's coast have necessitated the use of floating turbine technology, which is now becoming available to unlock the potential of offshore wind on the Pacific Coast2.
