Hexing has officially signed an agreement with De-Janees Concepts Ltd to jointly launch a 2 MW solar medium-voltage microgrid project in Saki, Oyo State, Nigeria. Equipped with a 3 MWh energy storage system, the project is planned for future expansion up to 10 MW. Upon completion, the project will deliver at least 22 hours of clean and stable electricity daily, initially benefiting 4,000 households as well as critical facilities such as schools, hospitals, and gas stations.
The implementation of this project underscores Hexing Electrical’s determination to provide clean energy solutions for communities, while marking an important milestone in its expansion into the African renewable energy market.
Engr. Isaiah Fatokun, Managing Director and CEO of De-Janees Concepts Ltd, and Ye Wenjun, Vice President of Hexing Electric Group for Africa, attended the signing ceremony for the Saki microgrid project.
Meeting Saki’s Urgent Power Needs
Situated in the Oke-Ogun region, Saki comprises 15 sub-communities with a population exceeding 500,000. Despite hosting over 100 gas stations, large hotels with hundreds of rooms, multiple schools, and a police station, the area has long been plagued by persistent power shortages and an unstable electricity supply.
The project will be implemented in three phases. The first phase, scheduled for completion and commissioning by December 2025, will deliver 2 MW of solar power through the Sango feeder to supply electricity to 4,000 households. The project will ultimately expand to 10 MW with the potential to upgrade to 30 MW in the future, aiming to cover more off-grid communities.
At the signing ceremony, Engr. Isaiah Fatokun, Managing Director and CEO of De-Janees Concepts Ltd, stated that the project aligns with Nigerian President Bola Tinubu’s “Renewed Hope Power Agenda,” aimed at driving economic growth, revitalizing local businesses, enhancing education, and significantly improving the overall quality of life for Saki residents.
Full-Scenario Medium-Voltage Microgrid Solutions
Hexing’s medium-voltage microgrid system is designed primarily for small grids with connection voltages of 40.5 kV and below. It integrates distributed PV systems, energy storage systems (ESS), coordinated control units (CCUs), power loads, monitoring devices, and protection equipment into a unified, intelligently managed system. These components work in synergy to form an integrated generation, distribution, and consumption microgrid, achieving precise local energy balance.
For the Saki medium-voltage microgrid project, Hexing Electrical provided a full-scenario solution encompassing solar PV modules, grid-tied inverters, energy storage systems (ESS), prefabricated substations, pole-mounted circuit breakers, and a smart energy management platform. Utilizing an 11 kV on/off-grid hybrid architecture, the project features core capabilities such as multi-energy coordinated control, medium-voltage equipment access, intelligent dispatching, and black start, ensuring stable and efficient operation even under weak grid conditions.
Key Equipment Components
The system adopts a hierarchical control architecture to achieve multi-energy coordinated control. At the local level, device-level PID control is implemented, such as PV MPPT tracking and battery SOC balancing. At the centralized level, the EMS provides intelligent, full-scenario microgrid management and delivers customized solutions, ensuring optimal system operation and highly efficient service delivery.
Through this hierarchical optimization structure, Hexing Power’s medium-voltage microgrid system combines precise device-level control with intelligent system-level management, supporting seamless grid-connected and off-grid switching functions such as pre-synchronization, parallel closing, and anti-reverse power protection. This architecture significantly enhances renewable energy consumption capacity, providing solid technical support for building a safe, clean, and sustainable modern energy system.
Multiple Control Strategies
Project Development and Government Collaboration
The project is spearhead-developed by De-Janees Concepts Ltd, approved by the Nigerian Rural Electrification Agency (REA), and funded by the World Bank. Ibadan Electricity Distribution Company (IBEDC), the local distribution utility, will provide grid access through its existing distribution infrastructure.
“This collaboration is more than just the delivery of our medium-voltage microgrid solutions; it is a concrete demonstration of Hexing Electrical’s vision as a ‘Global Expert in Green Energy and Clean Water Solutions,’” stated Ye Wenjun, Vice President of Hexing Africa. “We look forward to joining forces with our partners to light up Africa, bringing light and hope to more people living in darkness.”
The project has now entered the execution phase, with civil engineering works and equipment transportation progressing in parallel, and grid connection is expected within the next ten months. Upon completion, the project will significantly enhance energy security for the Saki community, stimulate local economic development, and improve the quality of life for residents.
Hexing Electrical will continue to drive development through innovation, utilizing green technology to light up every corner of the world in need of power.
