Linyang Energy Storage's 40 MW/120 MWh Mauritius BESS Project (Phase I) Successfully Connected to the Grid

On October 24, local time in Mauritius, Phase I of Linyang Energy Storage’s 40 MW/120 MWh grid-scale battery energy storage project in Mauritius was successfully connected to the grid. As the largest grid-side energy storage project currently in Mauritius, this marks a significant step forward in Linyang Energy Storage’s large-scale project delivery in African island markets, bringing a proven Chinese energy storage solution to the global energy transition.

Phase I comprises a 20 MW/60 MWh battery energy storage system (BESS) featuring a modular design that streamlines on-site installation, commissioning, and testing. On October 25, local time, the project successfully completed full-power charge and discharge tests, with the system operating stably and all key performance indicators meeting design requirements. The system features millisecond-level response, black-start capability, and grid-forming functionality, enabling it to provide voltage and frequency support when required by the grid. Linyang Energy Storage’s overseas products have obtained international certifications and test qualifications, including IEC 62133 and UL 9540A, supporting reliable, long-term operation in Mauritius’ challenging island environment, characterized by high salinity, humidity, and severe tropical cyclones. The successful grid connection and full-power testing demonstrate the system’s reliability under demanding environmental conditions and lay a solid foundation for Linyang Energy Storage’s further expansion into African island markets.

Throughout project execution, Linyang Energy Storage leveraged its global supply chain coordination and engineering delivery capabilities to maintain control over the process from equipment shipment to grid connection, demonstrating its expertise in large-scale energy storage system integration. During grid connection and testing, the BESS worked in coordination with the power grid and successfully completed a series of stringent technical tests. Following grid connection, the system will participate in peak shaving and frequency regulation through charging and discharging, enhancing grid flexibility and facilitating the integration of renewable energy. By mitigating the impact of intermittent power generation on grid stability, the project will also help address the challenges of accommodating additional renewable energy capacity and maintaining reliable grid operations in the future.

The Central Electricity Board (CEB) of Mauritius is working toward its target of generating 60% of the country’s electricity from renewable sources by 2030. As an island power system without external grid interconnections, Mauritius remains heavily reliant on fossil fuels. The growing integration of renewable energy is increasing the need for frequency regulation, renewable energy integration, and reliable power supply during evening peak demand. Energy storage has therefore become a priority resource in CEB’s efforts to enhance grid flexibility. The 120 MWh BESS supplied by Linyang Energy Storage is now entering operation with the completion of Phase I grid connection. With its millisecond-level response and grid-forming capabilities, the system provides real-time support for the island grid, serving as an operational asset in CEB’s efforts to build a cleaner, more stable, and more efficient energy system.

The successful grid connection of the Mauritius project not only demonstrates Linyang Energy Storage’s capabilities in system integration and engineering delivery under challenging island conditions, but also establishes a strong foundation for further expansion into island and coastal energy storage markets worldwide.

Looking ahead, Linyang Energy Storage will continue to drive innovation and deliver reliable energy storage solutions that support the global energy transition.
