The technology group Wartsila will supply a 7.8-megawatt energy storage system to a leading gold mining company to help achieve its climate targets and decarbonisation goals at a mine in Suriname. This is the first utility-scale energy storage system to be built in Suriname and Wärtsilä’s first energy storage project in the country. The facility is expected to become operational in late 2022.The integrated energy storage system will improve efficiency at the gold mine’s power station by reducing the need for emergency back-up spinning reserve, therefore lowering fuel consumption. The project is estimated to reduce the mine’s emissions by 5,600 metric tonnes of CO2 equivalent per year. This optimised energy system will extend to improvements across the lifetime of the engines and reduce operation and maintenance costs.The facility will include Wärtsilä’s GridSolv Quantum, a fully integrated, modular and compact energy storage system, as well as the GEMS Digital Energy Platform, Wärtsilä’s advanced energy management system. GEMS will control and optimise the portfolio of both the existing generating sets and the new energy storage system. GEMS will also evaluate opportunities to integrate renewable energy assets at the facility to further decarbonise mining operations, further reduce operations costs and provide clean electricity to surrounding communities.
