Summary of Offshore Wind Development Program in Brazil

Core Content

This report outlines the potential for offshore wind development in Brazil, focusing on three growth scenarios and their implications for energy production, infrastructure, and environmental considerations. It is prepared by the World Bank (WB) and the International Finance Corporation (IFC) under the Offshore Wind Development Program, in collaboration with the Ministry of Mines and Energy (MME) and the Energy Research Office (EPE). The report aims to support Brazil's energy transition by providing a comprehensive analysis of offshore wind opportunities and challenges.

Main Growth Scenarios

The report presents three offshore wind development scenarios:

#1 Base Case Scenario

• Projected Capacity: 4 GW by 2035, 16 GW by 2050
• Contribution to Total Generation: 3% by 2050
• Investment Required: US$40 billion by 2050
• Annual Installation Rate: ~1 GW/year
• Seabed Utilization: 1.2% of available seabed
• Location Focus: Primarily in the Northeast region
• Infrastructure Needs: Limited due to modest growth
• Impact: Offshore wind would be overshadowed by onshore wind, solar, and existing hydro and thermal production

#2 Intermediate Scenario

• Projected Capacity: 8 GW by 2035, 32 GW by 2050
• Contribution to Total Generation: 6% by 2050
• Investment Required: US$80 billion by 2050
• Annual Installation Rate: ~1.8 GW/year
• Seabed Utilization: 2.3% of technically feasible seabed
• Location Focus: Evenly distributed across the three target regions
• Infrastructure Needs: Transmission and port upgrades to enable development
• Impact: Offshore wind would be a significant contributor, but still secondary to other renewables

#3 Ambitious Scenario

• Projected Capacity: Not fully detailed in the excerpt
• Contribution to Total Generation: Likely higher than the Intermediate Scenario
• Investment Required: Higher than the Base and Intermediate Scenarios
• Annual Installation Rate: Higher than the Base and Intermediate Scenarios
• Seabed Utilization: Higher than the Base and Intermediate Scenarios
• Location Focus: Likely to include more regions and areas with higher wind potential
• Infrastructure Needs: Substantial investments in ports, vessels, grid, and manufacturing
• Impact: Could lead to significant job creation and economic development

Key Technical and Environmental Considerations

Wind Resource Potential

• Total Technical Potential: Over 1,200 GW (480 GW fixed, 748 GW floating)
• Regional Variations:
  • Northeast: Best wind conditions, with average wind speeds of 7–10 m/s at 100 m a.s.l.
  • Southeast: Good potential for both fixed and floating wind, with average wind speeds of 8 m/s
  • South: Largest seabed area (165,000 km²), with high wind speeds and significant technical potential (660 GW)
• Proximity to Demand Centers: All regions have favorable conditions for proximity to major cities and industrial centers

Environmental and Social Considerations

• Marine Biodiversity: The South region is almost entirely within an Ecologically or Biologically Significant Area (EBSA), increasing the need for careful planning and mitigation
• Sensitive Species: Areas with high biodiversity and migratory bird routes are identified, requiring environmental impact assessments and exclusion zones
• Marine Traffic and Ports: The Southeast region has significant shipping activity, necessitating careful port planning to avoid interference with major shipping lanes
• Marine Spatial Planning (MSP): The report emphasizes the need for a pragmatic approach to spatial planning to identify feasible development zones

Economic and Employment Impact

• Job Creation: Under the Ambitious Scenario, over 516,000 FTE jobs could be created by 2050
• National Gross Value Added (GVA): Estimated at US$168 billion under the Ambitious Scenario
• Local Content: The report highlights the importance of local content in driving economic development and job creation
• Supply Chain Readiness: Brazil has a nascent supply chain, with potential for growth in turbine manufacturing, substation components, and balance of plant (BOP) equipment

Financial and Policy Considerations

• Capital Expenditure (CapEx): Varies by scenario, with the Ambitious Scenario requiring the highest investment
• Levelized Cost of Energy (LCoE): Expected to decrease over time due to learning curves and economies of scale
• Tax and Policy Incentives: The report includes a color matrix of applicable incentives and a summary of potential tax and policy support for offshore wind
• Green Bonds and Climate Funds: Brazil has access to various green financing instruments, including climate funds and green bonds

Infrastructure and Supply Chain

• Port Infrastructure: Critical for offshore wind development, with gaps identified in both main and optional ports
• Substation Capacity: Required to be expanded to support the growth of offshore wind
• Grid Infrastructure: Needs upgrades to facilitate the evacuation of offshore wind energy to demand centers
• Supply Chain Readiness: Assessed across different components and services, with a focus on local content and supply chain development

Methodology and Analysis

• Methodology Overview: The report uses a schematic representation of the analysis steps and includes a detailed evaluation of technical, economic, and environmental factors
• Marine Spatial Plan (MSP): A key tool for identifying feasible development zones and managing environmental and social sensitivities
• Risk and Sensitivity Mapping: Provides a framework for assessing environmental, social, and commercial risks associated with offshore wind development

Conclusion

The report underscores the potential of offshore wind to complement Brazil's existing hydroelectric generation and contribute to a cleaner, more diversified energy mix. It highlights the need for strategic planning, investment in infrastructure, and the development of a robust supply chain to support large-scale offshore wind growth. The three scenarios provide a range of possibilities for Brazil's future energy strategy, with the Ambitious Scenario offering the most significant economic and environmental benefits, provided the necessary investments and planning are in place.
