"Asia Generation revenue increased by 18 million dollars to 212 million dollars, primarily due to higher volume in Pakistan and an outage at Ras Laffan in Qatar in 2006, partially offset by lower volumes in Sri Lanka," a company statement said.
"Gross margin decreased by 5 million dollars to 58 million dollars, primarily due to lower volumes in Sri Lanka and higher planned maintenance costs at Barka in Oman."
Technical problems with AES Corp's Kelanitissa unit, an Independent Power Producer (IPP) that operates a combined cycle base load plant, had kept it off the grid at the height of the dry season in recent weeks.
Generators at the Ceylon Electricity Board's Kelanitissa thermal complex had been frequently tripping during the last two months due to problems with fuel supply.
The CEB grid had also been subject to frequent failures.
However, the power utility has now got all its troublesome thermal generators on line.
The CEB runs a mix of hydro and thermal generators with a target of about 20 million units to be generated from thermal to conserve its hydro storage.
The utility has been forced to buy power from private power producers owing to a severe shortage of generating capacity.
