North Sumatera Hydro Power Tara F Khaira, MBA

Project Location

• North Sumatera Hydro Project is located in

North Sumatera Province, Indonesia

• North Sumatera is one of strategic province in Indonesia, where plantations, industry and trade have significant role on the economic developments.

• The Location could be reached by 2 hours air transport from Jakarta to Medan and 30 minutes flight from Medan to local airport. Then continue by land transportation around 1 hours to the nearest town and another 2-3 hours to project sites.

AVERAGE MONTHLY RAINFALL

• Generally rainfall occurs the whole years. • Mostly high rainy-season: September –December • Highest rainfall: September (365 mm) • Dry-season: June –July • Most driest month : July (102 mm ) • Average annual rainfall: 2325 mm “High Rainfall Area” based on Isohyet Rainfall

Map (2000 –2500 mm/yr)

FLOW DURATION CURVE (FDC)

• Average river discharge is designed at Intake Weir dependability of occurrence of 55%.

• Average annual rainfall (1977-1999): 2326.2 mm/yr High Rainfall Area.

• Favorable hydrology conditions to construct mini hydro power plants
