Sierra Leone, one of the countries with the lowest electricity access rates globally, has long faced challenges from limited power infrastructure and unreliable electricity supply. Only five of the 16 regional capitals receive partial electricity supply from diesel generators and hydropower facilities, while rural electrification remains severely constrained.
Sungrow, the globally leading PV inverter and energy storage system (ESS) provider, has commissioned the RESPITE Solar-plus-Storage Project in Sierra Leone.
This marks the West African nation’s first major national-scale power generation project completed and connected to the grid in nearly a decade. The project features a total energy storage capacity of 35MWh and integrates eight units of Sungrow’s PowerTitan Series ESS.
Backed by the World Bank, the RESPITE project represents a milestone in Sierra Leone’s power development journey. Like many energy projects in low-income countries, it faced structural barriers such as weak grid conditions, limited electricity affordability, and insufficient commercial viability, creating challenges in attracting commercial financing.
With Sungrow’s globally recognized bankability and proven reliability of its energy storage and inverter solutions, the project successfully addressed financing challenges and gained confidence from the World Bank.
This project is expected to increase Sierra Leone’s national electricity access rate from 16 percent to 36 percent, significantly improving power availability and delivering stable electricity to households, schools, healthcare facilities, and commercial and industrial users.
Sierra Leone Overcomes Challenges
Sierra Leone presents one of the most challenging operating environments for energy infrastructure given its fragile national grid and daily power outages of up to 18 hours. Leveraging Sungrow’s PowerTitan advanced black start and independent off-grid capabilities, the project team implemented an emergency response strategy.
It switched from grid-connected commissioning to off-grid operation. Through the system’s black start capability, it can automatically switch to black start mode and establish a microgrid without external grid support, using solar power to support onsite loads and create a stable electrical environment for commissioning.
Supported by standardized emergency procedures and a localized global spare parts network, Sungrow provides comprehensive support across installation, commissioning, and grid connection, delivering reliable value for efficient project execution and timely grid integration.
It utilizes advanced technologies and global project deployment expertise to help Sierra Leone overcome energy challenges and accelerate its transition toward sustainable clean energy.
