Resolute Mining - World's largest offgrid hybrid
Insights and Case Studies
Information
The Syama Gold Mine is currently powered by singular diesel generators that were no longer the most efficient compared to newer technology now available. At the mercy of diesel, notoriously a fluctuating high cost fuel, it has become an expensive solution. Furthermore, the generators had to run constantly to provide system stability that the mine needed.
After investigating the possibility of a grid connection, which was disregarded on the basis of time and cost, Resolute launched a tender with the target of achieving a 40% reduction in the cost of electricity (COE). With Resolute focused on securing a more environmentally friendly solution, the environmental impact of the power solution being offered was a key consideration.
Our pricing was structured with a combination of fixed and variable charges depending on electricity required, and evolving MW installed. It also includes an incentive programme where Aggreko shares between 25% to 50% of the resulting fuel savings if improved efficiencies for key performances indicators in the contract are achieved. This provides us with an incentive to further reduce the cost of power for Resolute, and we share that cost benefit directly with our customer.
As Aggreko had been providing and operating a 28 MW diesel power plant on the site that augments the existing diesel power station for a few years, we had both the reputation and credibility to step in and offer support.
A vast project needed a vast solution and we relished the opportunity to work with Resolute to deliver a bespoke cutting edge technical and commercial solution as part of a 16-year Power Supply Agreement (PSA).
