Hybridising existing mine power in Indonesia
Hybridising existing mine´s power delivers big on carbon, fuel and financial savings
- THE CHALLENGE
Remote mine with decarbonisation goal and reliable power need
- THE SOLUTION
Hybrid power package introduced to maximise efficiency
- THE IMPACT
Significant carbon, fuel and financial savings and a 10- year mine lifecycle extension
Client:Batutua Tembaga Raya (BTR) copper mine
Location:Wetar Island, Indonesia
Sectors:Mining
THE CHALLENGE
Remote mine with decarbonisation goal and reliable power need
Situated in a remote Indonesian island, BTR’s copper mine’s power requirements were currently solely met by thermal diesel power generation. Being their trusted power partner since 2015, Aggreko well understood their requirements.
Reliable and consistent power is crucial for this mine to ensure operational efficiency is fully maximised. Knowing that the Indonesian government was also pushing its mining industry to focus on the energy transition and the decarbonisation agenda, we spotted an opportunity to hybridize their current thermal power generation and facilitate the mine with decarbonisation while not sacrificing their operational productivity.

THE IMPACT
Significant carbon, fuel and financial savings and a 10- year mine lifecycle extension
As a result, the mine has been able to benefit from the latest technological upgrades and meet its sustainability objectives through their OPEX expenditure and without significant financial outlay.
Over the five-year contract duration, the mine will save up to 4.6 million litres of fuel, as well as reduce emissions by 12,340 tonnes of carbon, and reduced their overall cost by more than US$3.7 million. This is expected to extend the mine economic viability for an estimated additional 10 years. These significant savings not only benefit the environment, but ensures profitability of the mine’s continued operations and helps retain regulator and government support.
As power technologies continue to evolve, Aggreko’s energy as a service approach and ongoing investment in research and development gives the Wetar copper mine increased flexibility that will enable it to upgrade its power assets as new technologies become available.
