One of the world’s largest gold producers, Newmont Mining Corporation, based in Colorado, USA installed Cambridge Energy Partners’ (CEP) Nomad redeployable solar tracking system at their Akyem mine in Ghana.
The Akyem gold mine produces over 400k oz. annually and power is supplied by the local grid. Energy is one of the mine’s largest expenses and a major concern — power prices are high and the associated GHG emissions are significant.
Over the past 5 years Newmont had looked at various renewable energy projects to address it’s high energy costs, but no proposed solution could meet the minimum economic hurdles, primarily due to the mismatch between the 10-year life of mine and the 25-year life of the renewable energy system.
