Sri Lanka has run a Chinese built 300 MegaWatt power plant fully on coal with a full load connected to the national power supply on Friday night for the first time as part of its testing regime officials said.
"Today we ran the plant fully on coal," power minister Patali Ranawaka told reporters Friday.
On Friday night the plant had also been successfully connected to the grid at full load for the first time, officials said.
The plant can generate up to 315 MegaWatts of power but can export between 285MW to 300MW the grid after using part of the energy for its own operations such as running a coal crushing plant and its cooling systems.
Ranawaka said coal prices were also rising and at current prices the cost of generating a unit of power from coal was 6.40 rupees.
But diesel prices are also rising and the cost of liquid thermal generation was also rising.
Coal is mostly sold on long term contracts and utilities in many countries usually manage cost rises better than liquid fuels.
