Cisokan hydropower plant project needs $800m in investment
The Jakarta Post
State-owned electricity company PLN needs to invest US$800 million for a hydropower plant project located in Upper Cisokan, West Bandung, West Java.
“The funds will come from loans and internal PLN funds,” said Ahmad Daryanto Ariyadi, PLN major development unit (UIP) general manager for Java's central area I (JBT I), as reported by kompas.comon Tuesday.
At present, the main access road for the project was still under construction and was expected to be completed by mid-2019, Ahmad said, adding that the power plant was scheduled to operate by 2024 or 2025 with a capacity of 1,040 megawatts (MW).
The hydropower plant will use pumped-storage hydroelectricity (PSH) technology, in which the turbine is rotated using water pumped from a lower elevation reservoir to a higher elevation reservoir. The rotation of the turbine produces power.
Ahmad explained that the Upper Cisokan Hydropower Plant would be the first plant in Indonesia to use pumped-storage technology, although it has been widely used in Europe.
He said with the technology, the Upper Cisokan power plant would not rely heavily on conventional water resources because the turbine of the plant could pump the water to a higher elevation reservoir during the day.
“During the night – during periods of high electrical demand – the turbine will produce electricity, while in the day time, the turbine will pump the water up from the lower elevation reservoir to the higher elevation reservoir,” he added. (bbn)
