Energy Efficiency

Energy efficiency measures have been implemented in all Merdeka operations.

The fuel consumption of the Tujuh Bukit mining operation in 2020 decreased due to the temporary diversion of heavy equipment activities from mining activities to the heap leach pad location. As for the mining in Pulau Wetar, consumption of energy was down due to reduced activity in 2020.

In addition, the Wetar Project seeks to reduce energy consumption, among others by initiating a generator energy efficiency program, by managing peak and lowest energy use, using solar panels in lighting lamps in internal ports, and in surface water monitoring equipment. Meanwhile, energy consumption in mining operations and processing plants increased in line with the increase in processed ore and products.

We are reviewing the technical and financial feasibility of our efforts to consider the use of renewable energy sources.
