Goseong Green Power Plant
South Korea, Changwon
2018 – today

Every two years in South Korea, a new plan is prepared to ensure the East Asian state's energy needs are met. As part of the 6th Basic Plan for Long-term Electricity Supply and Demand (BPE), the Goseong Green Power Plant is built in Changwon with a nominal capacity of 1,000 MW. It is the largest privately owned power plant in South Korea.


A Herrenknecht EPB Shield was ordered for the construction of the power plant. The tunnel boring machine (TBM) with a diameter of 8,190 mm excavates a 770 meter long tunnel. Factory acceptance of the TBM takes place at the Herrenknecht subsidiary in Nansha, Guangzhou. The first 100 meters of the new tunnel have already been built successfully.


Environmental protection and maximum quality are already at the center of attention during construction of the new coal-fired power plant, which is 15% more efficient than other power stations of its kind: the ordered Herrenknecht TBM was largely built using professionally remanufactured machine components already proven in other projects. For a completely refurbished tunnel boring machine, the energy savings from remanufacturing are about 80 percent. Compared to a new machine, about 99 percent fewer materials are needed. A huge saving that conserves resources, lowers CO2 emissions and thus significantly improves the environmental balance.
