The current water level at Sirinumu Dam is 116.78 million cubic metres (MCM) says PNG Power (PPL) acting chief executive officer John Yanis.
The total capacity for the dam catchment area is 340 MCM.
There is an agreement by the State owned power and water supplier if the water level drops to 100MCM where Eda Ranu will use the remaining water in the catchment area to supply drinking water to Port Moresby and its surrounding areas.
And PPL will resort to fuel generators to fill the short fall to provide electricity.
“PPL has reduced (electricity) generation at Rouna Hydro. We have not reached the system 100 MCM yet at the dam,” Yanis told Loop PNG.
“And if we do, we will extract energy from the water from upstream before the water is collected from the storage pond for drinking.”
Eda Ranu today started water rationing to its customers to preserve the remaining 35 percent of water in the dam.
Rationing will be for an indefinite period.
