RedCap Climate Resilience – Impofu Wind Farms, South Africa

Supporting climate resilience through strategic environmental planning for wind energy infrastructure in South Africa’s Eastern Cape.

Client

Red Cap Energy (Pty) Ltd

Project date

2017

Red Cap Energy proposed the development of the Impofu Wind Farm projects near Oyster Bay, Eastern Cape, along with a 120 km-long 132 kV overhead power line to evacuate power to Port Elizabeth. Zutari was appointed in 2017 to undertake environmental impact assessments (EIAs) for the three wind farms and the basic assessment (BA) process for the transmission line.

The opportunity

The project aimed to contribute to South Africa’s renewable energy goals while ensuring minimal environmental and social impact. The challenge was to optimise the layout of the wind farms and grid line to avoid sensitive areas and reduce risks during statutory approvals. The location within a cluster of existing wind farms also raised concerns about cumulative impacts, requiring a robust and iterative assessment approach.

What we did

Zutari led a multidisciplinary screening process to guide the layout and alignment of the wind farms and transmission corridor. This included:

  • Sensitivity mapping to identify environmental No-Go areas

  • Overlaying technical spatial data to identify feasible alternatives

  • Applying a multi-criteria decision-making (MCDM) process using pairwise comparisons

  • Conducting ongoing bird and bat monitoring to inform iterative design

  • Engaging more than 10 environmental and social specialists and engineers


Zutari also implemented a unique stakeholder engagement strategy, starting early in the project and using multiple platforms to ensure inclusive participation from well-established interest groups.
Wind farm layout and grid corridor mapping, optimised through sensitivity analysis and stakeholder engagement.

The outcome

The project was successfully guided towards a sustainable outcome that integrated environmental, social and economic factors. The advanced screening and MCDM process saved time and costs by excluding unfeasible options early. Zutari’s early involvement enabled the team to influence planning and implementation, ensuring long-term climate resilience and community benefit.

The Impofu Wind Farms project demonstrates how strategic environmental planning and collaboration can unlock the potential of renewable energy while protecting ecosystems and communities. Zutari’s approach continues to shape climate-resilient infrastructure across South Africa.

Zutari was particularly happy about being involved from the earliest possible stage, as it enabled the project team to guide the planning and implementation of the project towards a sustainable outcome.
