Wind and Solar Resource Assessment and Financial Modelling at South African Ports

This study presents a detailed assessment of renewable energy potential and financial feasibility for wind and solar projects near South African ports. The study demonstrates how ports or its Special Economic Zones (SEZ)—which are strategic gateways for trade and Power-to-X (PtX) infrastructure—can harness local wind and solar resources to unlock PtX opportunities.

Key insights include:

• Resource Assessment & Financial Modelling: The study builds on the Environmental Screening Report and delves deep into identifying viable wind and solar resource zones near major ports and conducts techno-economic modelling to test project viability.
• Elevating PtX Pathways: Integrating the findings with the broader PtX landscape, the study supports the development of green hydrogen and derivative fuels (like green ammonia and e-fuels) that can be produced and shipped via port infrastructure—establishing a critical link between renewable generation and PtX value chains.
• Empowering Just Energy Transition: The study contributes to South Africa's strategic planning efforts that prioritize sustainable infrastructure, inclusive stakeholder engagement, and the alignment of port-based energy projects with South Africa’s burgeoning defossilization and industrial modernization goals

Why This Matters

Ports are not just trade hubs—they’re gateways for South Africa’s green energy evolution. This study equips policymakers, project developers, and investors with data-driven insights to:

• Design renewable energy and PtX projects that are both technically sound and commercially viable.
• Strengthen South Africa’s role in the growing global PtX economy.
• Advance equitable and sustainable development through strategic, port-based infrastructure.
