Sierra Leone’s energy future draws on more than one natural resource. SERL’s Betmai programme brings together hydropower, complementary solar development and transmission infrastructure in Tonkolili District.

The first hydro phase is 28.2 MW, with an estimated first-phase cost of US$110 million. The hydropower arrangement is a run-of-river weir.

A planned 12 km, 66 kV transmission connection links the Betmai powerhouse to a shared step-up substation. Hydro and solar are designed to evacuate power through that shared substation into the Transco-CLSG network.

Engineering, environmental work and community participation develop alongside the project. These connected responsibilities shape the way renewable resources become energy infrastructure.
