How does the hybrid power control system work?
The Balama Solar Power Station operates as a critical component of a larger hybrid energy infrastructure designed to supply the Balama Graphite Mine. The hybrid system integrates three distinct energy sources: the 11.25 MW solar farm, an 8.5 MW/8.5 MWh battery storage system, and an existing 15.4 MW diesel-fired thermal power source. Together, these components form a combined 35.15 MW hybrid power station. The synchronization of these sources allows for a more stable and efficient power supply to the mining operations.
System Integration and Synchronization
The core function of the hybrid control system is to synchronize the variable output of the solar farm with the storage capabilities of the battery system and the reliability of the diesel generators. The solar farm, developed by Solarcentury, generates electricity during daylight hours. This energy is not only used immediately but also stored in the 8.5 MW/8.5 MWh battery system. The battery storage plays a crucial role in balancing the load, storing excess solar energy for use during peak demand or when solar irradiance is lower. This stored energy is then synchronized with the existing 15.4 MW diesel-fired thermal power source. The diesel generators provide a baseline power supply and serve as a backup when solar generation and battery reserves are insufficient. This integration ensures a continuous and reliable power supply to the Balama Graphite Mine, reducing the dependency on any single energy source.
Impact on Diesel Consumption
One of the primary objectives of this hybrid configuration is to reduce the reliance on diesel fuel. The integration of the 11.25 MW solar farm and the 8.5 MW/8.5 MWh battery storage system is expected to result in a 35 percent reduction in diesel consumption. This significant decrease in diesel usage not only lowers operational costs for Syrah Resources but also contributes to a reduction in greenhouse gas emissions associated with the mining operations. The hybrid system allows for optimized energy management, where solar power is prioritized during peak sunlight hours, battery storage is utilized during transitional periods, and diesel generators are employed as a supplementary source. This strategic approach to energy management enhances the overall efficiency and sustainability of the power supply for the Balama Graphite Mine.
Ownership, Financing and BOOT Arrangement
The project operates under a Build-Own-Operate-Transfer (BOOT) arrangement, a financing model that structures the lifecycle of the asset between the developer and the primary offtaker.
