It appears that in both 2022 and 2024, Sri Lanka experienced a decline in hydroelectricity contribution to national electricity generation, necessitating the import of thermal oil to meet power demands.
However, in 2024, there's a shift towards higher contribution from Non-Conventional Renewable Energy (NCRE) sources and a focus on coal over thermal oil, likely resulting in reduced electricity generation costs compared to 2022. This shift in energy sources reflects efforts to optimize cost efficiency and sustainability in the electricity generation sector.
