Geita Gold Mine

Ensuring reliable power generation for remote gold mining operations in Africa.

Client

AngloGold Ashanti

Project date

With extensive experience in power generation across Africa, Zutari was appointed as the owner’s engineer by AngloGold Ashanti for two major power projects. The first was a 40 MW power plant at Geita Gold Mine in the Mwanza Region of north-western Tanzania, followed by a 30 MW power plant at Siguiri Gold Mine in north-eastern Guinea. Both projects were designed to provide stable and reliable energy for the ongoing operation of the mines.

The opportunity

Gold mining operations in remote African regions often face limited or unreliable access to grid electricity. AngloGold Ashanti required dedicated captive power plants to secure consistent and efficient energy supply, critical for maintaining productivity and safety standards at both mines.

What we did

Zutari’s involvement spanned from design and construction through to final commissioning. Acting as the owner’s engineer, we worked to reduce technical risks, ensure compliance with engineering standards, and verify that the plants met the client’s performance requirements.

Both power stations feature high-efficiency Wärtsilä 32TS dual-fuel generators. Zutari reviewed the engineering, procurement, and construction (EPC) design; conducted risk studies; and provided oversight for factory testing, construction, commissioning, and performance verification.

In addition, we carried out electrical network integration studies to ensure safe and effective connection with the existing mine infrastructure. Our scope also included the design of an overhead transmission line linking the Geita power plant to the process plant, and a fuel supply system from the depot to the power facility.
High-efficiency dual-fuel power generation systems provide reliable energy for AngloGold Ashanti’s mining operations.

The outcome

These projects overcame significant logistical and technical challenges associated with working in remote locations. Zutari’s multidisciplinary team delivered comprehensive project management and engineering support across mechanical, electrical, civil, structural, and control disciplines, ensuring successful completion and reliable long-term operation.

Beyond powering the mines, the electricity generated also supports local communities, creating lasting benefits for surrounding areas.

The Geita and Siguiri power plants demonstrate how innovative engineering, robust project management, and collaboration can deliver sustainable energy solutions in remote environments, enabling both industrial growth and community development across Africa.

The electricity from the mines also supports local communities, and it is rewarding to be part of projects that will serve African communities for years to come.
