The Batoka Gorge Hydro Electric Scheme is a transformative project aimed at harnessing the power of the Zambezi River to deliver clean and sustainable energy to Southern Africa. Positioned about 47 kilometres downstream of Victoria Falls, the scheme is a cross-border initiative that required exceptional technical expertise and strong collaboration between multiple stakeholders.

The Challenge

Developing a hydro electric project of this scale across two countries presented unique challenges. The project demanded a robust design, accurate risk assessment and financial viability while ensuring environmental and social considerations were met. The Zambezi River Authority needed a trusted partner to provide comprehensive advisory services covering technical, financial and legal aspects.

Our Role

Tata Consulting Engineers worked alongside Ernst and Young Advisory Services and Webber Wentzel to support the Zambezi River Authority. Our responsibilities included:

Innovative Solutions

Our team introduced design improvements that enhanced efficiency and reduced costs. We recommended increasing the capacity of turbine generator units, reducing the number of units from six to four in each powerhouse. We also proposed layout changes such as a saddle spillway and surface powerhouse design to minimise scouring of the plunge pool and shorten the construction timeline. These measures are expected to deliver an additional benefit of about 120 million US dollars through early commissioning.

Impact

The Batoka Gorge Hydro Electric Scheme will provide reliable renewable energy to millions of people, strengthen regional power networks and contribute to economic growth. Our advisory services ensured technical robustness, financial viability and timely execution for one of Africa’s most significant infrastructure projects.
