This project is located in the Rosebel mining area in Suriname, South America—one of the largest producing open-pit gold mines in South America. The equipment was first connected to the grid in November 2025 and reached full-capacity operation in December 2025. It represents Suriname‘s first large-scale centralized PV + energy storage project, employing a PV-storage-diesel microgrid model to replace diesel power generation, thereby achieving cost reduction and carbon abatement.
The PV-storage system directly supplies power for mining area production, replacing the original diesel generator sets.It is adapted to the high-temperature and high-humidity rainforest climate and supports functions including islanded operation, black start capability, and power smoothing. Following full system commissioning, it will supply approximately 36.5 million kWh of electricity annually, meeting approximately 17% of the mining area’s annual electricity demand, saving approximately 10,400 tonnes of diesel per year, and reducing carbon dioxide emissions by approximately 33,000 tonnes per year. Compared to pure diesel generation, it achieves a 30–40% reduction in electricity costs. The system ensures stable power supply and fluctuation mitigation, thereby safeguarding continuous production and equipment safety.
