3.2. Imported electricity Liberia imports electricity from neighboring Côte d''Ivoire and Guinea through the West African Power Pool (WAPP) interconnection, which involved 650 km of 225 kV transmission lines, with a transit capacity of ≤290 MW – making it the largest source of imported electricity for the country in 2020.
To overcome these challenges, Liberia has been exploring alternative solutions to reduce its dependency on imported fuels for thermal power generation. One strategy is to diversify the energy mix by increasing the share of domestic renewable energy sources, such as solar and wind power, for electricity generation.
With the solar collector''s heat storage tank temperature set at 573.1 K under extreme conditions, when the energy storage system needs to operate, both the temperature of the solar collector''s heat storage tank and the temperature of the heat transfer oil after solar thermal assistance are low, resulting in insufficient residual heat ...
