Vallibel Power Erathna said a 7.2 MegaWatt, Denawakaganga mini hydro project run by subsidiary Country Energy (Pvt) Limited, started commercial operations on February 14, 2012.
On March 01, Country Energy has issued new shares and the parent's share has fallen to 84.5 percent from 89.3 percent. A 6.2 million rupee 'deemed disposal gain' has been recognized as other income.
On December 15, 2011, Kiriwaneliya mini hydro Power project also run by Country Energy has started commercial operations.
But Vallibel Power Erathna said power generation fell 22.5 percent last year due to drought.
A tariff paid by the state power utility had also fallen. State run Ceylon Electricity Board pays some mini hydro firms on a formula based on its own costs in the past year.
In 2011 thermal generation fell with strong rainfall. But from mid 2011 rains failed. The tariff rises in the following year in such conditions.
