Recently, the 7.5 MW / 15 MWh photovoltaic-storage-diesel microgrid project constructed by China Energy Storage Technology in Conakry, Guinea, has completed trial operation and has been officially delivered to the client and put into operation.

This microgrid project integrates photovoltaic power generation, an energy storage system, and diesel generator sets, forming a complementary power supply mode. The system possesses dual capabilities of grid-connected and independent operation, allowing for flexible switching based on actual electricity load to enhance power supply stability and anti-interference capability. The project is expected to provide approximately 8.6 million kilowatt-hours of clean electricity annually, equivalent to saving about 2,700 tons of standard coal and reducing carbon dioxide emissions by over 7,200 tons.

The microgrid project adopts an operation strategy of "self-generation for self-consumption, with adjustable surplus electricity." This mode not only enhances the power supply security and regulation flexibility for the client's own project, with an expected annual electricity cost saving of over USD 725,000 for the client, but also provides independent power security in the event of a main grid failure, helping to ensure the continuity of production activities and playing a positive role in the overall advancement of the project.
