Additional information

Aggreko has signed a 16 year contract with Resolute to deliver a new hybrid power plant at the Syama gold mining complex in the south of Mali. 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 in 2023. Installation of the new power plant will be delivered in a two-stage approach: Phase 1 – Installation of three Wärtsilä Modular Blocks, based on Wärtsilä 32 engines providing a total of 30 MW of power, next to the existing power station and 10 MW Aggreko Y.Cube battery storage system for spinning reserve displacement in 2020. Phase 2 – Installation of one further 10 MW Wärtsilä Modular Block in 2022 and 20 MW of Solar power system in 2023. Once the solar system is installed, the batteries will also smooth out fluctuations in the solar power output to facilitate integration into the hybrid system.
