Innovative thinking drives cost savings at Gold Fields Ghana

Wednesday, 12 July 2017

Gold Fields’ Tarkwa mine in Ghana is saving an extra US$90 000 + in energy costs per month thanks to Emmanuel Bosomtwe, Electrical Engineer, and the Business Improvement and Electrical Engineering teams.

Electricity at the mine village was unreliable and very expensive but Emmanuel and the two teams collaborated to devise a more cost-effective solution. Instead of a costly traditional power line feed, it now uses a mix of electricity from Gold Fields Ghana’s recently commissioned gas turbines and Ghana’s main electricity provider. The team saved even more by doing all the installations themselves.

The result? The village now spends about 50% less on electricity per month.

Initiatives such as these support Gold Fields’ commitment to using energy more efficiently and reducing our carbon footprint. “This is a great example of how collaborative effort that seeks continual improvement can save energy costs and thus reduce All-In Sustaining Costs (AISC),” comments Tsakani Mthombeni, Vice President: Group Head of Carbon and Energy.

Well done Emmanuel and the rest of the team:

Eugene Swanepoel, Electrical Superintendent (CIL plant)
David Larbi, Engineering Business Improvement Analyst
Olo George Omana, Projects Electrical Engineer
Roger Adamah, Projects Superintendent
Kofi Ako, Junior Management Accountant (CIL)
Elliot Twum, Engineering Manager
Augustine Wireko Asubonteng, Finance Manager (Damang)
