A senior climatologist in the committee that studied a proposal to produce artificial rain for hydropower generation has urged the Government to conduct a thorough cost-benefit analysis and environmental impact study before taking the project beyond its trial stage.

The Ceylon Electricity Board (CEB) and the Sri Lanka Air Force (SLAF) this week signed an agreement to facilitate the rainmaking initiative with technical expertise from the Thai Government. The project is expected to benefit Sri Lanka in periods of drought to avoid buying expensive power from independent power producers, Power and Energy Minister Ravi Karunanayake was quoted as saying.

“There were nine island-wide power system failures from 2006 to 2010 but there were none since 2010 till the last incident,” said Athula Wanniarachchi, President of the CEB Engineers’ Union (CEBEU).

“This is due to the successful implementation of automatic system restoration methods adopted by the CEB in 2010.”
