'No rainfall until the end of April'

A Public Utilities Commission of Sri Lanka briefing note on Sri Lanka's power supply situation for March makes the following observations:

Even with full availability of thermal power plants, about 550 MW of hydro power contribution is essential to meet the night peak demand.

Based on past trends, there will be no rainfall until end of April. Hence, daily major hydro dispatch level is required to be kept below about 6 GWh/day in average, to ensure the availability of hydro reservoirs until end of April.

Under this condition, the loss of thermal generation capacity the system can withstand without requiring power cuts will be 560 MW in January. Due to demand growth, this will reduce to 500 MW in February and 350 MW in March.

Hence, it is required to ensure that unit 1 of the coal power plant resumes generation in January 1, 2017.

Also, it is required to ensure the continuous fuel availability for oil fired power plants, in terms of, Sufficient imports of low Sulphur furnace oil and availability of fuel transportation to West Coast power plant.

Continuous furnace oil supply from Sapugaskanda Refinery.

Sufficient production/ imports of Naphtha and Diesel / Auto Diesel and availability of fuel transportation to power plants in Kalanithissa.
