This initiative can supply the mine’s power requirement during peak daylight time A solar, battery and genset hybrid system at Balama Graphite Mine in Mozambique will transfer to the mine operator, Syrah Resources, at nil cost at the end of its 10-year BOOT term. The entire solar photovoltaic array of 20,832 solar modules with a surface area of around 5.4 hectares is fully integrated into the battery system. During operational testing over 10 days, integrated power supply from the solar and battery hybrid system and diesel genset was achieved with 33% of the total power supplied via the solar and battery hybrid system and ~34% average savings in diesel consumed per kWh power generated. The solar plus battery storage system will contribute at least 35% of the Balama Graphite Operation’s average site power requirements. This will significantly reduce the mine’s diesel consumption by ~16,000 litres per day. This hybrid project can supply the mine’s power requirement during peak daylight time when the plant is operating and continuously if the plant is not operating. The mine’s diesel power generation plant will provide baseload power requirements overnight and incremental power requirements during daylight hours, dependent on solar irradiation, power availability from the hybrid system and overall site power demand. An automated power management system manages the operation of the hybrid system and diesel genset to optimise integrated power generation at the mine. ESI |
