The mine is the world’s first fully automated underground gold mine. The site’s owner, Resolute Mining Limited, aims to be a leader in mining innovation and, by investing in future-proof solutions, make its Malian operations more environmentally friendly. The move to modernise the off-grid power generation capacity to meet rising demand provided the perfect opportunity to deploy a more reliable and efficient solution that would not only deliver significant cost savings, but also dramatically reduce CO2 emissions. Wärtsilä partnered with Aggreko Power Solutions to provide four Wärtsilä Modular Block enclosures, each equipped with a high-efficiency, medium-speed Wärtsilä 32 engine. The total output of the solution is 40 MW. The solution’s very high efficiency and superior instant load capabilities make it ideal for isolated power systems. In addition, the modules are quick to install and dismantle if and when they need to be relocated. This also enables new business models such as power-as-a-service and rentals, a sector that is now moving towards gas and longer contracts.
Increased capacity from a reliable, efficient and future-proof solution
Because the current diesel generators can no longer meet the mine’s power demands for the coming years, Resolute will replace them with four Wärtsilä Modular Blocks providing 40 MW of power and being more efficient and having lower lifecycle costs than high-speed technology traditionally used in the mining sector. The high efficiency and superior instant load capabilities of the Wärtsilä engines, are ideal for isolated power systems. In addition, the modules are quick to install and dismantle if and when they need to be relocated. The Wärtsilä Modular Block also enables new business models such as power-as-a-service and rentals, a sector that is now moving towards gas and longer contracts. The customers can choose between ownership and rental whichever suits his business model best.
Easy integration with renewable energy and storage systems
This future-proof solution can meet any increase in demand by accommodating future renewable energy sources – in this case, solar power and battery storage. When complete, the new hybrid solution, for which Wärtsilä’s engines will generate over half of the power, will help to enhance Resolute’s environmental impact by reducing carbon emissions by around 20%. The Wärtsilä Modular Block solution is ideal for providing grid stability and balancing when integrating renewable energy. Thanks to its modular design, the solution can be expanded by simply adding more enclosures.
