Namgang, South Korea

Output increase of about 20% - Small & Mini Hydro

At the end of 2016, ANDRITZ HYDRO received an order from Korea Water Resources Corporation (K-water) for the turnkey refurbishment of the existing Namgang hydro­power plant in South Korea. The project site is located some 100 km west of Busan, South Korea’s second largest city.

ANDRITZ HYDRO is the main contractor, being responsible not only for the entire electro-mechanical scope of supply, but also for the disassembly of the old turbine equipment, the necessary civil work structure for the new turbines, Electrical Power Systems (EPS) and mechanical auxiliary equipment. After refurbishment, HPP Namgang will be equipped with two Compact Axial Bulb turbines – each with a runner diameter of 2,850 mm and a power output of 9 MW. This represents an increase in power output of about 20% over the old turbines.

Along with the previous delivery of 14 Bevel Gear Bulb turbines for the “Four River Restoration Project” in 2011 and 2012, the order for HPP Namgang is an additional important reference for the Compact Hydro business unit of ANDRITZ HYDRO, further strengthening the market position of the company in South Korea.
