Aggreko, a leading provider of mobile modular power and energy services, has signed a 16 year contract with mining company Resolute to deliver a new hybrid power plant at the Syama gold mining complex, located in the south of Mali, west Africa. Aggreko will install, operate and maintain a 40 MW thermal power plant and a 10 MW battery storage system, with a further 20 MW of solar power planned for 2023. Works on the power plant are due to start immediately, with the first delivery of power being targeted for Q3 2020.
The hybrid solution, which will be administered through a Power Supply Agreement, is estimated to reduce Syama’s power costs by 40%. Once all the renewable power sources are fully installed it will also reduce carbon emissions by approximately 20%.
Installation of the new power plant will be delivered in a two stages:
Phase 1 will see the installation of three Wärtsilä Modular Blocks, based on Wärtsilä 32 engines providing a total of 30 MWe, next to the existing power station and a 10 MW Aggreko Y.Cube battery storage system for spinning reserve displacement in 2020.
Phase 2 will see the installation of one further 10 MW Wärtsilä Modular Block in 2022 and 20 MW of solar power in 2023.
The initial site infrastructure layout will include space to accommodate a fifth 10 MW Wärtsilä Modular Block, enabling the mine to add additional power capacity if needed in the future to support growth or expansion plans.
The thermal element of the project is being implemented in partnership with Wärtsilä. The project is one of Wärtsilä’s early sales of its new product, and Aggreko’s first contract to deliver it.
